Boot Managers / PLoP Boot Manager and installing Windows XP On Toshiba G20
« Last post by Frixi on March 07, 2019, 15:35:58 PM »

I have a problem. I was get the Polp manager i was burned on cd.
Its works , i can boot it from cd, but after i switch the USB drive option its start work but nothing happen.
I tried with make my win iso with rufus, but the machine cant find it.
Then i tried with easy2boot usb and same this. In test mode i see my isos on it ,so i think the problem is on the laptop.
I tried it with all 4 USB slot.
Its TOSHIBA Qosmio G20, and have 2 SATA ( :S ) HDD in. ATM WIN7 on, but its very slow with it. I try magic back to WIN XP.
I tried with nLite integrate SATA drivers to windows iso, but after i used F6 method , some work and then a BIGBLUESCREEN :(
I try on it 2 days but i my ideas are ended.
I'mt not sure I can use regular Plop (just Plopkexec), since my laptop apparently has a built-in USB hub. Do you know if it's possible to boot Windows's BOOTMGR from plopkexec? Though I don't seen to need GRUB in the case of Linux, simply because I'm using Plopkexec.
Well, you did as I would have done.

Just remembering from the documentation that Plop needs BOOTMGR for booting Windows or GRUB in case of Linux, may you confirm that both Windows and Linux have their loaders installed on respective partitions  ? I guess yes, just brainstorming.
I'm actually using Plop over PXE boot, served off a Raspberry Pi. I've tried booting from the external drive using the "boot from USB" menu option, as well as by trying to boot any of the hdb partitions. Booting HDA partitions only boots the main drive in the laptop.

I am no sure to be the one fixing your problem, but a least helping to make the case more obvious.
Firstly, are you talking about Plop Linux booted from its live-CD, or do you make use of a permanent install of the Plop boot manager on your system ?

Secondly, do we agree that you chose "booting from USB" from the menu, when trying to launch your operating systems from your external HDD ?

As the title says, I've tried to use Plop to boot both Windows 10 (BIOS, not UEFI), and Ubuntu (same), and no matter what I try, Plop won't detect it nor boot from it. It only detects the built-in ssd of my laptop. Using Plopkexec, however, I am able to load Ubuntu manually (it's also not automatically detected, so I need to manually run kexec). I can give more information, but as I don't know what is and isn't helpful, so let me know.

Boot Managers / Re: Option ROM seems to have no effect. Asus Pundit-S

4. Then I flash the file via aflash.
5. Reboot, System comes up, without plop :(

After having flashed your enhanced BIOS, have you been thinking about switching the boot device order, in the Award BIOS setup ?

I guess that once you inserted the Plop option rom in place of the genuine boot-from-the-network module, nothing may happen until you would actually instruct the BIOS... to boot from the "network" (i.e. to chain to the Plop rom).

I know that the thread is old, but I would be interested to share observations and results with you, as a P4S8L motherboard owner. I try to install the Plop option rom to the same Bios as yours. The goal here is to give USB booting capability to the machine and make of it a very nice platform for Lakka retro-gaming distribution.

Hope to see you online in the future.
Boot Managers / Re: directions on how to build rom

The RHCF used to be a first class resource with regard to BIOS modding and flashing, providing lot of advices and BIOS customization tools to be downloaded. Sadly, the forum does not exist any more. Its knowledge is gone, but some of the tools are still available at the domain <>, which the forum used to make its main binaries repository. For instance:

Thanks to Google, it is possible to retrieve a few more direct downloads whose hyperlinks vanished:

There might be other file of interest. Unfortunately, the folder is setup for not displaying its content: either you know (or guess) the full URL, either you stay out.

Hope this may help you to push Plop into the BIOS of your machine.

I've followed these instructions:;f=52;t=000063
Good day, Elmar! I've just tested your Plop Boot Manager 5.0.15 as a part of coreboot+SeaBIOS opensource BIOS
by adding your plpbt.img floppy to my fresh coreboot.rom build with the following command:
Code: [Select]
./coreboot/build/cbfstool ./coreboot/build/coreboot.rom add -f ~/Downloads/plpbt.img -n floppyimg/plpbt.lzma -t raw -c lzma
I am happy to tell you that Plop Boot Manager seems to be working great - at least successfully boots Linux from USB flash drive! :)

However, I am really concerned by that Plop Boot Manager source code is not open:
it could be hard to justify keeping a closed source proprietary software as a part of opensource BIOS
for security considerations: theoretically any closed source software could contain the backdoors,
and having it as a part of BIOS is a permanent security risk that I would like to avoid if possible.

Elmar, please could you release the source code of Plop Boot Manager?

Also I've just learned that you are going to release a new Boot Manager soon.
Don't know if it would be open source, but it would be really nice if you could
at least liberate the source code of plpbt-5.0.15 which came out almost 6 years ago

P.S. if you became curious about this opensource bios, please visit the coreboot board status page, to check
if your motherboard is supported , or maybe you could get one? personally I am using AMD Lenovo G505S laptop :
it has a powerful quadcore A10-5750M CPU without AMD PSP hardware backdoor (an equivalent of Intel ME backdoor),
supports 16GB of RAM and could be found in good condition for just $100-$150. Great choice for security conscious people

Best regards,
Mike Banon,
