I have a copy of the original VGA(file made my the perl program) and flash

I have read all the documents on the linuxbios website more than twice.
You need to enable two CONFIG options in your Mainboard Option.lb
When I enable those I get errors. Some kind of undefined erros.
I have just started reading up on LinuxBIOS and am keen to use it on my
EPIA-M powered Linux server (for... speed! - ok, and coolness-factor)...
and wondered why GRUB isn't listed (or suggested) as a payload option...
seems an obvious choice to me (not knowing the inner workings of
LinuxBIOS), also, has anyone started working on a keyboard based config
utility such as is found by pressing F2 or similar at bootup in
I have added some changes to the decompression options. All work on
abuild, little or no testing has been possible. It's really just some
CONFIG_PRECOMPRESSED_ROM_STREAM means that linuxbios need not run any
programs in the makefiles to compress the rom stream. The rom stream is
already compressed; linuxbios needs to include code to uncompress it
properly. It is an error to set this variable, and not set one of the
variables mentioned below; this error is only caught at compile time
(Sorry! This is called "Why we need to change the Config system". )
CONFIG_COMPRESSED_ROM_STREAM now means that the rom stream is nrv2b
compressed. This name is deprecated, I have tried to remove every usage
of it in the tree, and this name WILL GO AWAY soon.
CONFIG_COMPRESSED_ROM_STREAM_NRV2B now means that the rom stream is
nrv2b compressed. If CONFIG_PRECOMPRESSED_ROM_STREAM is not set, the
makefile will try to run nrv2b on the file.
CONFIG_COMPRESSED_ROM_STREAM_LZMA now means that the rom stream is lzma
compressed. The lzma uncompresser is not tested.If
CONFIG_PRECOMPRESSED_ROM_STREAM is not set, the makefile will try to run
lzma on the file.
I have tested all combinations of these options in a build, and they all
properly build a linuxbios rom image. I have not yet tested them on a
board, but almost no targets use them; I hope not to cause trouble.
Also, due to other issues, I have moved the destination of all
decompressers to the 16 MB boundary. This Is A Hack. But, the other way
(at the end of linuxbios, usually 2M) ran into trouble on OLPC and would
have run into trouble on other systems. We need streaming decompressers.
It is an error to:
set CONFIG_PRECOMPRESSED_ROM_STREAM and not set one of the others, or
to set more than one of CONFIG_COMPRESSED_ROM_STREAM,
CONFIG_COMPRESSED_ROM_STREAM_LZMA. This error is only caught at compile
time. Again, sorry.
All this builds. Few platforms save OLPC use it. I doubt this change
will break much if anything.
I don't know if this already went out to the list cos I've just signed up and I haven't gotten a copy of it back yet so I'm reposting...
Basically, has anyone tried using Grub as a payload... I haven't delved much into this yet but seems to me I would have to rebuild a new LinuxBIOS image and flash it if I want to change where the kernel is loaded from (partition or filename) or any other build-time options.
Also, has anyone thought about putting in some kind of configuration utility as is found by pressing Delete or F2 or whatever on regular BIOS'?

I have a epia board with a VT8231 and the via C3 processor. I can install
linuxbios and get it to boot with serial port output using filo. The vga
bios is 49kb. Where do i insert the VGA bios is it at the begining of the
flash chip starting at address c0000 ? Can I boot linux bios without
fallback and just the normal and vga? Is it even possible to get this vga
working in linuxbios? How does the vga boot process work, I don't
understand why one would need to insert the vga bios into the flash chip.
Couldn't one just jump to the vga bios instead?
can somebody bring a monitor or two?
I can't bring outlet strips -- mine are all rated at 120v.
my enet switches may not work -- power warts all rated at 120v
usb and ps/2 keyboards would be good -- can somebody bring one or two?
