May you post your bios? What version of ATOM-15 are you using?

Hello ! Sorry for digging up this old thread, but this is the only place I found mentioning this model of card with ATOM-15 !

After successfully reading my card's ROM (with amdvbflash_dos_4.68) and patching it, lbios wouldn't load it (under FreeDOS - I couldn't get the HP USB / Win98 boot disk to boot) so I didn't want to risk bricking my card.

Attached, the patched and unpatched rom files with output from ATOM-15 1.6.

This is absolutely not critical, but it would be even better if I could access BIOS setup and show off my custom boot logos on the cab's screen :)

I could never get Lbios to work at all. If Lbios works with the original unmodified BIOS but not with the Aomt-15 one, i'd be worried, but otherwise you're probably fine. Which is not me taking responsibility for your actions, lol. Just saying :)
