So there are two issues: a) DOS isn't supported and b) the floppy as a boot device isn't supported. That will make it a very difficult sell for mobo manufacturers. Can you imagine me buying a Linux PC with LinuxBIOS and it crashing. How am I going to repair it then?

So I've been following the developments of this board a little. If I'm
not mistaken, the board now works right?
If that is the case then I only have a few questions. I have a project
where it would be nice to not have to get LinuxBIOS working on our own
boards (which we are in the process of doing). Though we need a flash
root directory, I guess I can have a CF in an IDE connector but was
hoping that with this board it was possible to use a DoC type solution.

I have just subscribed to this mailing list.
I am new to linuxbios and this project seems to have good prospectives.
I have just built romimage for Intel Clearwater motherboard and tried to
flash it into the bios, but Intel flash utility (phlash) refused to do
I failed to find any procedure or documentation for this motherboard on
how to make this motherboard work with linuxbios.
All i have right now is sources, which i have been examining during the
past several days. They seem to compile ok, so i want to flash at this
I know that common practice is to use disk on chip, but this motherboard
has zif flash socket instead of dip one.
Please, tell me how to flash romimage into flash.
Thank you in advance.

In the UK they cost about GBP20 - so I guess that's about EUR30 / USD30 in
the rest of the world...

Because they do not have a large enough capacity. Standard BIOS chips are
2megabits (= 32 kilobytes), which is not neough to hold a Linux kernel.

The main thing which DoC does which you can't do with standard Flash Roms is
to format them as a Silicon Disc, and put a file system into them.

Yes, but they're too small.

You can program a Flash Rom chip on your motherboard - no external programmer
needed - that's how you upgrade the BIOS even if you're not doing anything

I own a via EPIA mobo that I use for GPS/music playing in my car.
It currently takes about 50 seconds to boot into my program
I am wondering if linux bios would help me in accelerating the boot time
Hi, I was wondering if there were avaiable prepackaged binaries for
Linuxbios ROMs. I don't want rpm of course (!) but I think that a
linuxbios image configured to boot from hda(1?) for a specific
motherboard (the pcchips one seems to be quite popular) may be very
useful; perhaps there are many configuration parameters, but I guess
resoanable defaults can be set and one would recompile everything only
if specific customizations are needed.
bye, thank you
Thanks a lot! I will try it! :)

The difference is mknbi/mkelf that come standard with etherboot when
the process the linux kernel start the kernel in 16bit mode and run
it's BIOS code, mkelfImage simulates the effect of the 16bit BIOS
code by reading LinuxBIOS tables or making the needed BIOS calls
itself, and then it enters Linux at it's unofficial 32bit entry
mkelfImage can take either a bzImage or a vmlinux.
