PLoP Boot Manager as a ROM module?

[qiet72]

Hi,

Do you have any plans or know if it is possible to convert PLoP Boot Manager to a BIOS ROM module just like they do with the Etherboot/GPXE project?  The idea is to have PLoP Boot Manager code placed permanentely into the BIOS - replacing the network boot code would be a good candidate.  The question is: is it small enough to fit there?  I would guess it would have to be under 64K in size for that to work.

the boot manager is available as option rom

Hi,

Thanks for the info.  I also noticed the info in the boot manager status section - I should have checked the webpage first.
The version I have plpbt-testqiet72-3.zip does not seem to have the rom module - only the floppy/iso/kernel binary files.
Do you have a link to the latest test version (September?) with the option rom module?

One more question: can you configure the rom version like you can with plpbt.bin?

at the moment i did not create a new rom with the latest test version. i hope i can do it during the weekend. the next version of plpcfgbt will configure the option rom too.

Great!  I should have some time in the weekend for testing if you need me.  I'll keep an eye on the forums.

Hi,

Unfortunately, most of my test laptops are Phoenix bios'es and I don't have the tools to insert your rom module.  I guess I will just have to settle for floppy/iso methods.

Good news,

I have finally found a flash rom I can play with: a 3Com network rom chip that I can flash via the linux flashrom utility.  So I should be able to play around with the rom version of your boot manager.

Any news regarding making the configuration program work with configuring the rom files?

cool

Any news regarding making the configuration program work with configuring the rom files?

the config program is the last program that i update.

Hi,

I successfully replaced the pxe rom code in the 3com network adapter with your rom module.  I verified that the code was the same "./flashrom -p nic3com -v plpbt.rom" but apparently the code does not work.  I can execute plpbt.rom by enabling the bios option "Boot From LAN First" but when the code executes, it just shows a blinking cursor and hangs.  Luckily I can recover by disabling the bios option and re-flash with the original network pxe rom code.

I was thinking, when I had to flash the rom, the rom file had to be exactly 65536 bytes in size.  The rom file I got from you is only 43155 bytes, so i padded it with "dd if=/dev/zero bs=1 count=22381 >>plpbt.rom". Does the rom module need to have a signature like 55AA in the end?

[Elmar]

please post the original rom

[qiet72]

Here you go.  The rom is 3Com's mba software which provides a pxe/tcp/ip/rpl/novell stack.  It's works fine if the romchip is flashed with this software.

i think the problem is that my rom is an isa rom and you need a pci rom. i will update the boot manager rom to a pci rom

[gzk101]

Is there any  NIC with pci can use your rom? or it's only for BIOS?

hi,
now its possible to create an ISA and PCI option ROM
see http://www.plop.at/en/bootmanager.html#plprom

Look at this ,plz.

C:\a>plpbtrom -vendorid=0x1022 -deviceid=0x2000 plpbtrom.bin a.bin
a.bin created

C:\a>bromcfg a.bin
PMODE/W DOS Extender v1.33

BROMCFG 1.02 - BootRom Configuration

Load a.bin (43008 bytes) ...

Check ROM:
ROM-Signature: Ok!
ROM-Size: 43008 Bytes
ROM-Checksum: Ok!
Pointer to PCIR: not found! - Pointer to $PnP not found!
No PCIR header (ISA-ROM)
No $PnP header (ISA-ROM)

Change configuration (Y/N)?n

No pcir header ? Why?

Sorry for my poor English.

[Elmar]

ups, thanks for the info
i fixed it, you can download the new plpbtrom version

Now OK.Thank you.

btw,Would you mind to add a switch such as "press HOTKEY to enter plop boot manager " to this rom?

[Elmar]

btw,Would you mind to add a switch so as "press HOTKEY to enter plop boot manager " to this rom?

[Elmar]

internet resources suggests asus customise its bioses in such way that is unlikely to flash it
directly inside bios?
