[Qemu-discuss] QEMU with real bios

[Maksim Ratnikov]

Good day. I have a task to run at QEMU real BIOS for Q35 motherboard.  And now I have some problems.

For example: QEMU hang up at this code (GDB log):

0x00000c19 in ?? ()
1: x/i $cs*16+$eip
0xf0c19:    add    -0x7c9a,%ax
(gdb) 
Watchpoint 1: $eax

Old value = 1979000527
New value = -664136
Watchpoint 8: $eip

Old value = (void (*)()) 0xc19
New value = (void (*)()) 0xc1d
Watchpoint 9: $eflags

Old value = [ PF SF ]
New value = [ PF AF SF ]
0x00000c1d in ?? ()
1: x/i $cs*16+$eip
0xf0c1d:    add    $0x4,%si
(gdb) 
Watchpoint 6: $esi

Old value = -294404
New value = -294400
Watchpoint 8: $eip

Old value = (void (*)()) 0xc1d
New value = (void (*)()) 0xc21
0x00000c21 in ?? ()
1: x/i $cs*16+$eip
0xf0c21:    loopw  0xf0c19

I don't know why....
Can you help me  or may be somebody doing something like this?
