Award bios on qemu

edit

How did you run the award bios in qemu? Which version exactly? On Windows or Linux? This is very interesting :-) Gelip (talk) 23:36, 6 January 2014 (UTC)Reply

User:Gelip: Linux. I dumped the ROM with flashrom -r bios.bin and ran it with qemu -bios ./bios.bin. Funnily enough, the end result depended on whether I enabled KVM or not: with KVM it booted relatively cleanly (I could get even into setup, though the screen was overwritten with garbage and the emulator had a tendency to halt emulation without even a possibility of rebooting the VM), while without KVM I got a "BIOS ROM checksum error", with the BIOS falling back to the boot block. Not sure how it depends on kernel or QEMU version. Cannot remember the exact versions either — it was probably QEMU 1.4. When I try the same thing now (1.7.0), both methods give me a checksum error.
I am quite lucky to have a BIOS which displays anything at all, actually. The best I got from other BIOSes is some debugging messages on the serial port. Keφr 17:17, 7 January 2014 (UTC)Reply

OK, thx. I found other working IWILL P55XB2 bios in Bosch emulator 2.6.2 for Win. Working POST, CMOS Setup and MS-DOS e.g game Electro Man Gelip (talk) 22:08, 8 January 2014 (UTC)Reply
