Actually i tried GDB and failed to build the image.. I got section overlap error and was not able to solve it. What i didnt understand is Why coreboot can't run a VGA ROM which seabios can? What is the big difference while executing VGA ROM in coreboot and seabios? >From the log you can see seabios emits some warning messages(fail handle_155fXX) but still it continues to run the VGA ROM, where x86emu or realmode hangs with error messages in seabios fail handle_155fXX:23(86): a=a0005f38 b=000008c1 c=00000003 d=0000c000 ds=a000 es=c000 ss=a000 si=00000000 di=00000003 bp=000077cc sp=000077be cs=c000 ip=3115 f=0002 Real mode Real mode stub @00000500: 422 bytes Calling Option ROM... oprom: INT# 0x8e41a854 oprom: eax: 8a000885 ebx: 0e21e039 ecx: 00028101 edx: 2989b606 oprom: ebp: 58000a58 esp: c0010004 edi: c668404c esi: c2650304 oprom: ip: e6b0 cs: 8831 flags: 00002900 Unexpected Exception: 6 @ 10:f6fdd07d - Halting Code: 0 eflags: 00010012 eax: 00007776 ebx: 00008831 ecx: 0010ef73 edx: 001059b1 edi: c0010004 esi: 8e41a854 ebp: 00002900 esp: 0000774a > -- > Thanks, > Joseph Smith > Set-Top-Linux > www.settoplinux.org > > > ------------------------------------------------------------------------------- > DISCLAIMER: This e-mail and any attachment (s) is for authorised use by > the > intended recipient (s) only.
