Hi! Linuxbios is working prety well now on my Epia mII 10k, but a few problems:
1. I can't get VGA to work. I've extracted it from a original-bios booted system with dd if=/proc/kcore of=video.bios.bin bs=1 count=65536 skip=790528 and then appended it to my filo payload like the HOWTO says I've to do, and modified the config file with all the options in EPIA howto, but nothing shows up on my monitor (tft screen, has it something to do with?)
2. If I boot up my mobo without the PCMCIA/CF module on, it boots properly but, if I put it on and try to boot, linux bios does somethings and then reboot, forever. any known bug about this?
thanks!
Here is the complete log of my bootup process, from bios to log-in... I can't understand so much of the bios part :(

It has something to do with VGA, I had similar problems (have been back to them so they are most likely still there). The Unsupported int number would change for me. If I powered down (hold power button down) the machine it would start up properly the next time. It wasn't something that ALWAYS happened, but fairly often it would.

Ralph Brown's Interrupt List is not very helpful either: http://www.ctyme.com/intr/int-b8.htm
Looks rather like a bug elsewhere..

Hm. The problem happens earlier. int 0x15 is something that the VGA BIOS would probably install, but this does not seem to work. Thus there's a hardcoded response handled in src/mainboard/via/epia-m/mainboard.c (v1) function handleint21()
Looking at above code, int0x15 gets called with eax=0x5f01 (besides lots of other values) - a case that is not handled in handleint21() at all.
There needs to be some way to call into interrupts set up by the executed option rom, or otherwise functions like handleint21() will have to be added and changed for every minor release of a vga bios update.

There's a potential hint in src/arch/i386/lib/idt.c:biosint():
// cases in a good compiler are just as good as your own tables. switch (intnumber) { case 0 ... 15: [..] #ifdef CONFIG_PCIBIOS case PCIBIOS: [..] #endif case MEMSIZE: [..] #ifdef CONFIG_INT21HANDLER case 0x15: [..] #endif default: [..] }
It looks like this case construct was done for readability, but in fact some kind of interrupt lookup table is needed to handle things correctly.

guilty as charged. I tried to make it readable but had no idea that we would need a table. Ignorance on my part.

Not in this case as David explained. I actually assumed there was some problem with 16<-->32bit jumping if an option rom is allowed to set up it's own int-handler or something. This question will come back when we want to have raid controllers or scsi adapters installing their own int 13 for booting from attached disks though.
