Ronald,
I am having difficulties with the VIA Epia M 6000 and LinuxBIOS snapshot 
2158 dated 9 January 2006.
The board has just one IDE disk attached.
Here are the POST codes I observe :
... A few codes going fast
FE, stays here for 4 seconds while IDE disk is being spinned
97
80
88
FF
00 Hangs here. At this point, the RUN LED of the POST card keeps 
blinking very fast.
NB : Board runs fine with the original BIOSes, as well as the ones I 
downloaded from VIA Web site.
Screen remains black, inactive all the time.
I have followed the instructions in the EPIA-M HOWTO, in particular 
capturing the ACPI dsdt and generating the file dsdt.c.
You will find below a copy of the dsdt -tc step which generated errors 
and warnings.
dsdt was captured on original BIOS version 1.35 from VIA (Phoenix BIOS).
I have also captured the video BIOS and added as indicated in the 
documentation (video.rom.bin first). I am attaching my Config.lb and 
Makefile
Can you let me know if there is anything I can do to fix the issue ?
Thanks for your help and best regards

Flashing BIOS
Did it with the Willem programmer, in fresh new chips, so that I could 
safely play with LinuxBIOS
