Nice work so far. I just applied the patch, followed the instructions in Nick's HowTo and flashed linuxbios to my Epia-M10000 (1). The only thing I see on the serial console is:
LinuxBIOS-1.1.8.0Fallback Fr Okt 28 19:21:21 CEST 2005 starting... Enabling mainboard devices
I used the default epia-m Config.lb (attached) with filo. Loglevel is 8. The board has 256MB of single sided DDR memory.
Should I increase the loglevel to 9 to get more information? Or any other ideas?
One thing I don't really understand in the HowTo is, that you change:
cat fallback/linuxbios.rom > linuxbios.rom to cat /video.bios.bin fallback/linuxbios.rom >linuxbios.rom
in the Makefile. This means, that the video bios is at the beginning of the ROM file. Is that correct?
In the next step I have to get the original BIOS back on the chip. Since I do not own a Bios-Savior, a friend with a programmer has to do this. I think he has to know the format of the ROM-File which flash_rom uses when dumping the BIOS. I assume this is Intel-Hex Format, right?
