adlo-epia.patch This is for ADLO. Since it includes changes specific to EPIA, it should not (entirely) go into CVS. Note that this includes serial debug patch by hcyun, and EPIA doesn't work without it. Perhaps a timing problem?
standalone patch with stuff specific to EPIA probably would be better.
as for timing isuses you may want to play with ide driver.
pirq-EPIA.bin This should be put at util/ADLO/pirq. It was taken from LinuxBIOS, not Award BIOS (I think it makes sense). Of cource, VGA BIOS is also required and it must be taken from your box.
Actually it is not clear if this particular stuff is needed at all. Initally we were using it to get Win2k to work, but later on it came out that windows boots without this stuff anyway. Perhaps it would be needed to get FreeBSD to boot.
