1. Introduction
The Plop Boot Manager is a small program to boot different operating systems.
The boot manager has a builtin ide cdrom and usb driver to access those
hardware without the help/need of a bios.
You can boot the operating systems from harddisk, floppy,
CD/DVD or from USB.
You can start the boot manager from floppy, CD, network and there are many more ways to start the boot manager.
You can install the boot manager on your harddisk. There is no extra partition required for the boot manager.
The Plop Boot Manager was written by Elmar Hanlhofer.
If you need help, post it to the
forum
or send me a message with the
contact form.
The current version is plpbt-5.0.10.zip.
Overview of install/start modes
| Hard disk installation |
The boot manager will be installed as primary boot manager to your
hard disk. No extra partition and required. The
boot manager will be in the first
sectors of your hard disk before the first partition begins.
|
Start from external media
Floppy
CDROM/DVD
USB drive
|
Its not required to install the boot manager to your hard disk. You
can start it from those media and use the boot manager with some
limitations.
|
Start from other boot managers
LiLo
Syslinux
Grub
Grub4Dos
Grub2
Windows boot.ini
Windows BCD
|
You can still use your prefered boot manager and additionally use features
from the Plop Boot Manager (like boot the usb drive,...).
The boot manager can run in hidden mode, so you have for example an entry
in your prefered boot manager to boot the usb drive and when you use this
entry then it starts
immediately without any additional menu. This can be useful for the usb boot function.
|
| Start from network |
With help of pxelinux its possible to start the boot manager from the
network.
|
| Start from your bios as option rom |
You can store the boot manager as option rom in your bios. There
is no need for any hard disk or anything else to start the
boot manager. It can be used as PNP part of your bios or
the boot manager can hook the INT19 to take control as first boot device.

6. Harddisk installation
There are many ways to install the boot manager to the harddisk. If you want
run the boot manager without harddisk installation then see
Running from Windows boot menu, LILO, GRUB, Syslinux, Floppy, CD.
Warning Linux users: Install LILO or GRUB to the boot sector of your Linux instead
of the Master Boot Record (MBR). The Plop Boot Manager is not a Linux loader and cannot start
Linux without LILO, GRUB, Syslinux and similar!
The install program
There are 2 versions of the install program. Basically both versions do the same.
The only difference is that plpinst.com creates a backup file
plpback.bin to restore harddisk sectors for a complete
boot manager uninstall.
The second version plpinstc.com skips the backup part. You have
to use the second version for installation from write protected media like CD's or
if you install from network or any other boot manager.
The install programs are installing the boot manager always on the first harddisk of your
computer.
Install program menu
1. Full boot manager install
With this option you install the boot manager to your harddisk.
If you have an installed operating system, then the install program creates a
profile for you to boot this operating system.
With the installation from floppy, the install program makes a backup of the sectors
where the boot manager will be installed. The install program writes the backup to
the floppy disk. With this backup it's possible to remove the boot manager completely
from your harddisk. If you use the CD installation, then it's not possible to
restore the sectors. In this case the uninstall routine creates a new MBR to boot
the current operating system. The partition table data won't be changed.
2. Write mbr loader only
A small program (the loader) is required in the MBR to start the boot manager.
Operating systems like Windows XP are writing during the installation their own
small program into the MBR. If you install Windows XP after the boot manager, then
Windows XP will start instead of the boot manager, because the loader is overwritten
with the program from Windows XP. To setup that the boot manager starts before Windows
XP you have to use Write mbr loader only.
3. Boot Manager update
With this, you can update the boot manager. But only updates with boot manager v5 are working.
4. Complete uninstall
Warning, this option is only available with the installation from floppy.
The install program takes the backup that was saved on the floppy disk and writes it back
to the harddisk.
Warning, if you changed anything with the partition table, then do not use this option!
5. Short uninstall
With this option, the program writes a new MBR to start the current operating
system. The partition table will be unchanged.
6. Set Boot Manager screen to textmode
Configures the Boot Manager to start in textmode.
7. Change destination harddisk
Set destination harddisk to install the boot manager.
8. Boot Manager hotkeys
See Hotkeys.
9. Reboot
The computer will be restarted.
Harddisk install using Floppy with a disk image
A floppy disk image is a file that contains every sector of the floppy disk. You cannot copy
the image file on a floppy disk like a common file. It's required to use a special program that
writes sector per sector of the image file to the floppy disk sectors. There are many programs available to
do this.
Download the current boot manager plpbt-5.0.10.zip.
Extract it to get the floppy disk image. You find the disk image in the install directory.
The name of the file is plpbtin.img
How to create the floppy:
DOS: You can use diskimg.com
with diskimg -d a -w plpbtin.img
Windows: Write the disk image with the program rawwritewin to the
floppy disk
Linux: dd if=plpbtin.img of=/dev/fd0
Harddisk install using CD with an ISO file
Download the current boot manager plpbt-5.0.10.zip.
Extract it to get the iso file. You find the iso file in the install directory.
The name of the file is plpbtin.iso
Notice: The CD installer makes no backup for a complete uninstall.
See The install program.
Windows:
You can use Nero, or the free program
CDBurnerXP, or any other program
that can burn ISO images.
Use the option like burn ISO on CD or
burn ISO Image. Then choose the boot manager ISO and burn it.
Linux:
cdrecord
is the linux program to burn ISO images to a CD.
Burn the ISO with cdrecord:
cdrecord -v dev=<devicename> <iso image>
Example:
If you access your CD burner with /dev/hdd
cdrecord -v dev=/dev/hdd plpbtin.iso
Harddisk install using DOS
Download the current boot manager plpbt-5.0.10.zip.
Extract it to get the install program. In the install directory there are 2 install programs
(plpinst.com and plpinstc.com)
for using under DOS.
plpinst.com creates a backup file plpback.bin
for a complete boot manager uninstall. plpinstc.bin makes no backup. Use
plpinstc.com for write protected media like CD's.
Harddisk install using the Windows boot menu (2K, XP, VISTA, Win7)
Download the file plpgenbtldr-0.7.zip
and extract it.
Create a directory like c:\plop. You can use any directory you want.
Copy plpinstc.com and plpgenbtldr.exe to your c:\plop directory.
Rename plpinstc.com to plpbt.bin.
As administrator/with administrator rights open a command shell and change to c:\plop
Then start plpgenbtldr
This program searches for the file plpbt.bin In the current directory.
plpgenbtldr generates the file plpbtldr.bin.
Adding to the boot menu. Windows 2K and XP is different to Windows VISTA and Windows 7
Windows 2K, XP
add the line below to your c:\boot.ini
c:\plop\plpbtldr.bin="Install Plop Boot Manager"
Windows VISTA
open notepad as administrator and create a file c:\boot.ini
add those lines
[boot loader]

|
3. Setup
3.1. Partitions
You can manage your partitions here. The install program creates an entry for all
primary partitions it finds. The names are from HDA1 up to
HDD4. HD means harddisk.
HDA stands for harddisk A and
is the first harddisk. The numbers 1-4 are the numbers
of the primary partitions.
Notice for linux users: HDA has nothing to do with the devices in linux like
/dev/hda.
Edit label
You can change the label for the partition. This label is used in the boot manager.
The maximum length is 16 chars.
Select Device
Here, you choose the harddisk of the partition.
HDA = Harddisk 1
HDB = Harddisk 2
HDC = Harddisk 3
HDD = Harddisk 4
Partition ID
There are 2 ways to set the ID of a partition.
1. Enter partition ID
You can enter the hexadecimal value for the partition.
2. Select ID from list
This list has the mostly used partition ID's. If the requested ID is not in the list,
then use Enter partition ID.
View/Edit/Copy data
This is used to change the values of partitions in the MBR.
BP means boot manager partition. This values are stored
in the boot manager.
P1-P4 this are the current values of the primary partitions
in the MBR.
You can edit the hexadecimal values in the partition table. You can select a
row with s (select) and paste the values to the row
where the cursor is with p. With this
function, you can import partition values to the boot manager or change values in the MBR.
This can be very useful in emergency cases.
Clear partition data
Clearing the data means clearing of the partition data in the boot manager. The data on the
partition itself is unchanged.
Reset changes
Use it if you changed something and you want to restore the whole values of the partition
in the boot manager. This is possible until you close the partition edit window.
3.2. Profiles
Profiles are used to start different operating systems from different harddisks and partitions.
It's also possible to detect changes in the MBR made by other software and import or forget the changes.
If you have an operating system installed and you install the boot manager, the installer creates
a profile to boot the current operating system.
Edit label
You can edit the label of the profile. This label is shown in the main menu. It's useful to use a
label to see what operating system is going to boot. The maximum length is 16 chars.
Show in main menu
With this option you select if the profile is shown in the main menu or not. Only visible profiles
can be booted. It also has effects on the default profile in the
boot manager setup.
Linked partitions
You select from which harddisk, partition and bios device number you want to boot with this profile.
You can also select what partitions or cleared partitions should be used for the MBR.
Configure partition entries
There are 3 states for a partition entry
1. a selected partition
Press enter to choose a partition from a list with all partition of this harddisk
available from Partitions.
If another software change this entry in the MBR, the boot manager detects this change at the
next startup. You can choose if you want to import the new values or forget them.
2. don't touch
The partition entry in the MBR will not be changed from the boot manager. That is the default setting.
If a software changes this entry in the MBR the boot manager cannot detect this change.
3. cleared
The boot manager set's this entry to 0 in the MBR. An operating system cannot detect that there is/was
a partition.
WARNING: if the boot manager has not stored the values of the partition in "Partitions" then you lose the
partition values in the MBR and you cannot access the data on the partition. It's possible to restore
those values, but it's better, easier and safe to store the values in Partitions.
Partition programs will say this is unallocated space! Do not partition this
space! You can lose data if you do it wrong.
Linked partitions - hotkeys
b set boot partition.
You select, what partition you want to boot with this profile. The boot manager set a bios drive
number automatically. It's possible to change it with another key.
c clear partition.
You set this entry to "cleared" and the boot manager cleares this entry in the
MBR when you boot this profile.
d don't touch.
You set the entry to don't touch and the boot manager
does not change this entry when you boot this profile.
e edit boot flag.
The boot flag has the bios drive number used by the boot sector routine. In some cases it's required to change
this value.
r remove boot flag.
Here, you remove the boot flag from the profile.
l set logial partition.
You can set to boot from a logical partition 1-4 of an extended partition. Change the logical number by pressing "l".
L1 = first logical, L2 = second, ...
Clear profile data
You can clear the profile data in the boot manager. The data in
Partitions are not changed.
Reset changes
Use it if you changed something and want to restore the whole values of the profile in the boot manager.
This is possible until you close the profile edit window.
3.3. Boot manager
Startmode
The boot manager has two modes to start. With the user interface menu
and hidden.
For the hidden mode, you have to set the bootcounter and you have
to select a default
profile. The default profile boots after the countdown.
The user can not see that there is a boot manager in the background. If you want to
go into the boot manager, then press ESC.
Boot countdown
You can enable and disable the countdown.
If the bootcounter is enabled, the boot manager waits the given time and starts
after the countdown the last used profile or the default profile, depending on your settings.
Edit boot countdown
Choose between 1 and 99 seconds.
Select at start
At start, the boot manager set the bar to the selected option. This works for the
hidden start mode too.
You have the following options
1. Last booted profile
2. Default profile
3. Floppy
4. CDROM
5. USB
Default profile
You can select the default profile from a list of all visible profiles.
Show floppy boot
Show the floppy boot option in the main menu.
Show cdrom boot
Show the cdrom boot option in the main menu.
Show usb boot
Show the USB boot option in the main menu.
Force USB 1.1
Use USB 1.1 controller even if there is a USB 2.0 controller.
Mode 1: Ignore the EHCI Controller
Mode 2: Setup EHCI Controller and set all ports to the companion host. Some controllers
need this option to force usb 1.1.
Use Mass Stor Dev
Use Mass Storage Device. Boot the X mass storage device that was found. Other devices are ignored.
Textmode after boot
You can select the textmode during the startup of an operating system.
Choose between "don't change" or 80x50.
Graphicmode
Select the screen resolution in the boot manager. Choose between textmode 80x50 and
graphicmode 640x480, 800x600, 1024x768, 1280x1024.
Zoom animation
Enable and disable the window animation.

Select the boot manager font or the bios font.
Starfield
Enable and disable the starfield animation.
Masterpassword
Setup the master password. Disable the boot manager password protection with an empty password.
Setuppassword
Setup the setup password. Disable the boot manager setup password protection with an empty password.
9. Configure the Boot Manager binary plpbt.bin with plpcfgbt
plpcfgbt-0.8.zip is a tool to configure
the binary version plpbt.bin of the boot manager. This program is available for Windows and Linux. You start the program from
a command shell. If you run the program without parameters then you will see the help information.
Usage: plpcfgbt [OPTIONS] file

-forceINT: This forces the boot manager to hook the INT 19h/INT 18h. If you have a PNP bios, then the
boot manager does not use the PNP bios feature of the boot device sequence. The boot manager will be started before any
boot devices is tried (when INT 19h mode is used) or the boot manager is the last program that is started when all boot devices
failed to boot (when INT 18h mode is used).
-INT18: Hook INT18h instead of INT19h. INT19h is the default mode.

Difference plpbtrom.bin and plpbt.bin
The only difference is that plpbtrom.bin gives the control of the boot
process back to the bios with a far return if you press esc. plpbt.bin
makes a reboot with int 19h.
You can configure plpbtrom.bin like plpbt.bin with plpcfgbt.
You can enable/disable a hotkey to stat the boot manager.
How to test a ROM
You can test your rom file with the free virtual machine qemu.
qemu -hda harddisk.img -option-rom plpbt.rom
If you have no harddisk image file then take one from the qemu download page
or use a floppy image.
qemu -fda floppy.img -option-rom plpbt.rom
How to flash an AMI bios
Do this at your own risk! This can damage your pc.
Download the Ami bios flash utility and save your current bios.
AMI Homepage
Its a DOS program, run the following command from a DOS floppy to save your bios
afudos /obios.rom
-
Use the Windows tool MMTools
to replace the network rom with the plpbt.rom.
Load the file bios.rom
Find the network option rom. It has the id 20, the name PCI Option ROM
and the RunLoc number VendorID:DeviceID of your network card. Maybe there are other option roms
in your bios. Take care that you choose the network option rom.
Click on it that its marked.
Click at the Replace Tab
Load as Module file the plpbt.rom file.
Press the Replace button
Press the Save ROM as and give it the name mybios.rom
Now comes the dangerous part. Flashing the bios.
I suggest to set the bios to the default settings and save it. Then boot from a dos floppy and run
afudos /imybios.rom
Do not turn off the pc during flash. After the flash has completed, go to the bios and do again a reset to the
default settings.
If all is ok, you should be able to configure the bios and start the boot manager during the boot process.
How to flash an AWARD bios
Do this at your own risk! This can damage your pc.
Download the Award bios flash utility aflash. You should find it at
your Motherboard homepage in the bios section.
Run it from a DOS floppy and save your current bios to a file. Give it the name bios.rom.
Search the file cbrom in the web. There are different version, not all will work
with your bios file, so you have to test it with different versions.
Run cbrom bios.rom /d
This should list all parts of the bios rom. I cannot give you the command to replace the rom. None of the
cbrom programs where able to display the content of my bios rom file.
You have to test it by your self.
When you updated the bios rom file, then flash it.
I suggest to set the bios to the default settings and save it. Then boot from a dos floppy and run
with awdflash.
If all is ok, you should be able to configure the bios and start the boot manager during the boot process.
12. Disable the USB driver under DOS
If you run DOS and the Plop USB driver is loaded, then you can disable the USB driver
with
plpdisd-0.1.zip. When you
disable the driver, then you are able to load other DOS usb drivers.
You can run
plpdisd from
config.sys
DEVICE=\plpdisd.exe
It's also possible to run it from the autoexec.bat or command line.
13. Hidden partition / Cleared partition
There is a important difference between "hidden" and "cleared" partitions.
Hidden Partition: Operatings systems, backup soulutions and so on
can see them but they ignore them. I would say, this is a pseudo hidden partition.
Cleared Partition: No program (except the boot manager) knows that
there is/was a partition defined in the MBR.
This is really hidden.
It looks
like unallocated space for every program. That means no other program can
access the data on that partition (with some work and searching the harddisk
there are still ways to
access the data). There is a risk, if you repartition
the harddisk, you will overwrite your invisible partition and all data
on it if you do it wrong.
14. Hide a partiton
This is an example: A partition should be visible in one profile and hidden (and not cleared) in another profile
Lets say you want to have the second partition on HDA (HDA2) on one profile visible
and on another hidden (and not cleared).
-
Use an empty entry in partitions. Give it
the label "hidden hda2".
-
Select the device HDA.
-
Go to "VIEW/EDIT/COPY DATA".
-
Move the cursor to P2 and press "s". Now move up to "BP" and press "p".
-
Press ESC and go to "Partition ID". Choose "Select from list". Choose the hidden version
of your partition.
-
Press ESC and save your changes.
-
Go to "profiles".
Now you can assign the
"visible" version of your partition to one profile and the "hidden" to another profile.
15. USB info
-
Only USB mass storage devices are supported. The USB support
allows to boot from
usb harddisk, usb sticks and usb cardreaders. USB floppys and CD/DVD drives are not working.
-
There is no USB HUB implementation. It's required to connect your USB device directly
to the USB port of your computer.
-
The USB implementation works on many computers. If it does not work on yours, please contact me.
Maybe we can fix it.
Current status see Bootmanager Status.

Download demoinstall.wmv
(demoinstall.zip). The quality is not the best but you see all required steps.
I hope its useful.
17. Windows XP and Windows Vista dual boot with hidden (cleared) partitions
The goal is to install Windows XP on the first partition
and Windows Vista on the second partition. I want that no windows has
access to the partition of the other Windows. There should be a third partition
that will be used as shared partition. Both Windows have access to this partition.
There are many ways to do this. I will describe one way.
It works only with the Harddisk installation!
What should be the result
- Windows XP on partition 1
- Windows Vista on partition 2
- A shared partition for both Windows as partition 3
- No Windows has access to the other Windows partition
- Realized with the Plop Boot Manager (harddisk installation)
Basic conditions
- The harddisk is not partitioned
- No boot manager is installed
The description
Install Windows XP
At first install Windows XP. Create with the Windows installer
a partition with the size you want. I use a 10GB partition. Install
Windows XP on this partition.
Setup Partitions
When you installed your Windows, go to the Disk Management
and create a second primary partition for Vista and
a third primary partition for the shared data.
Install the boot manager
Now comes the boot manager part. Boot from the boot manager install floppy or CD.
Install the boot manager to the harddisk and then reboot.
Configure the Windows XP profile
The boot manager created a profile called "os harddisk 1" to boot Windows XP.
It also imported the 3 primary partitions. The names are HDA1, HDA2 and HDA3.
Now go to setup and profiles. Select os harddisk 1.
Give it the new label windows xp.
Select linked partitions. Press enter at the first slot
of HDA and select HDA1.
At the second slot press c to set it to cleared.
You can leave the third slot as don't touch or select
HDA3. See the difference at configure partition entries.
Configure the Windows Vista profile
Now leave the configuration of Windows XP and go to an empty profile in Profiles.
Give it the label windows vista. Set show
in main menu to yes.
Now select linked partitions. Press at the first slot
c to set it to cleared.
At the second slot press b to set the boot flag.
Press enter and select HDA2. On the third slot choose the same
as for windows xp (don't touch or HDA3).
Install Window Vista
Go back to the main menu. Now you see windows xp and windows vista. Move to windows vista
and press Enter.
This writes the profile settings to the harddisk. The booting will fail, because Vista
is not installed. Now boot the Windows Vista install DVD. In the installer you should see
at the partitions screen at first an unallocated space (there is xp installed) and 2
primary partitions. Select the first primary partition to install Windows Vista. when the
Windows Vista installation has been finished, it's possible, that Vista
is booting immediately and the Plop Boot Manager does not come. In this case use
Write mbr loader only from the Plop Boot Manager install floppy or CD.
Now you should have two bootable Windows on your harddisk and they don't know from each other.
You can share data between both with the shared partition.
Windows Vista on the second harddisk
It's similar to the previous description, if you want to install Windows XP on the first harddisk and
Windows Vista on the second harddisk. The second harddisk is HDB in the boot manager.
So install Windows Vista to the first partition of the second harddisk. Set in
the vista profile/linked partitions the first slot of HDB to
HDB1 and press b.
The boot manager will set the boot flag to 81h. This should be
ok for your installation.
18. Dualboot Windows XP and Windows 7
Here are short instructions for a complete new installation of
your pc with dualbooting WinXP and Win7. It doesn't matter if you use 32 or 64
bit versions.
Take care, all data on your pc will be deleted!
Boot the Win7 install DVD. Remove all partitions from the harddisk. Create a partition for Win7.
The install program will create 2 partitions. One with about 80MB for the Win7 boot files and a
second partition with the Win7 files. Create an additional partition for WinXP. Now you see
3 partitions. Install Win7 to the second partition. After the Win7 installation is complete, install the Plop
Boot Manager. After the Boot Manager installation go to the Boot Manager Setup, then Profiles, then
"OS HARDDISK 1". Change the name to "Win7". Go to linked partitions and press enter on the first position of HDA
and select HDA1, on the second select HDA2 and on the third press "c" for cleared. Now leave the profile settings
for Win7. Use now an empty profile to create the WinXP profile. Give it the name WinXP, visible in main menu "yes".
In linked parttitions select for HDA on the first position HDA3, press "b" to set the bootflag on the first position.
On the second press "c" to set it cleared. On the third press "c" to set it to cleared too. Go to the main menu
and press enter on WinXP. You will be not able to boot this partition because XP is not installed currently.
If you get the message about invalid boot signature, then press "n" to abort. Now boot the WinXP
install CD. You should see now only one partition. Install WinXP there. After the installation
completed then start the Plop Boot Manager install CD and use "Install mbr loader only". Reboot, the boot manager
will tell you about partition changes. Press "y" to import the new values. Now you should be able to boot
both systems.
19. Using the Boot Manager as USB harddisk driver for DOS
I know this is very special. Maybe it's useful for some people. You have to configure
the plpbt.bin with plpcfgbt to use int19h
instead of booting the operating system.
plpcfgbt int19h=on plpbt.bin
Now you have to start plpbt.bin with a boot manager
like grub,
syslinux or what ever during boot time
(supported boot managers see here). Choose USB and the boot manager
will install the usb driver and go back to your boot manager. If you start DOS you will
have access to your usb drive as last harddisk. But remember, the usbdrive is only as "read only" device available.
If it works for you then use plpcfgbt int19h=on stm=hidden cnt=on cntval=1 dbt=usb plpbt.bin
To disable the usb driver from DOS see plpdisd.
20. NOD32 Virus report
This problem was fixed but with the new NOD32 versions it's back. It's a false report.
21. FAQ's - Frequently asked questions
I booted DOS from USB and I cannot write on the drive
Are there plans to add write support in the future
The boot manager detect's my usb cdrom, but booting hangs
My USB keyboard does not work when I booted from USB
Can I use my PCMCIA Card to boot from USB
I want to install the boot manager from my USB device, but I cannot choose my internal harddisk
I use plpbt.bin and it forgets my settings
I can not boot from my SATA CD/DVD drive
-
I booted DOS from USB and I cannot write on the drive
My drivers have no write routines implemented. You want to
know why? My intention was to have USB drivers for UHCI, OHCI
and EHCI controllers in my tiny boot manager. The space to install
the boot manager without the need of a partition is very limited.
So there was no space left for write routines.
-
Are there plans to add write support in the future
It's in my mind, but there are no fix plans.
-
The boot manager detect's my usb cdrom, but booting hangs
USB CD/DVD drives are not supported.
-
My USB keyboard does not work when I booted from USB
USB keyboards are not supported by my drivers. When you boot Linux or Windows,
then your keyboard will be available when those operating systems are taking
control over the USB hardware.
-
Can I use my PCMCIA Card to boot from USB
No, PCMCIA is not supported.
-
I want to install the boot manager from my USB device, but I cannot choose my internal harddisk
The problem with installing on the internal (in this case the second) harddisk
with the installer
is, that the installer imports the partitions from the usb device and
thinks this are the partitions of the first harddisk. When the boot
manager boot's later from the real harddisk then the imported partitions are
not correct. You see the problem? Sure it would be possible to add an option to
handle this situation, but there are so many other ways to install the boot manager, that
there are no plans to add this feature to the installer (except, many people request this feature).
-
I use plpbt.bin and it forgets my settings
You have to configure plpbt.bin with plpcfgbt. All changes you make within
the boot manager menu are only valid until you reboot. The changes are not saved.
-
I can not boot from my SATA CD/DVD drive
SATA CD/DVD drives are not supported. Only IDE CD/DVD drives are working.
