Kevin,
SeaBIOS initializes my VGA correctly the first time through, but if I
do ctrl-alt-delete, the screen is no longer updated. Do you have any
suggestions as to how to fix it?
Here's the snippet:
Attempting to map option rom on dev 02:00.0
Option rom sizing returned f5000000 fffe0000
Inspecting possible rom at 0xf5000000 (dv=014110de bdf=200)
Copying option rom (size 63488) from 0xf5000000 to c0000
Checking rom 0x000c0000 (sig aa55 size 124)
Found option rom with bad checksum: loc=0x000c0000 len=63488 sum=7e
The last line is the only new one. The others are exactly the same.
This is another difference, but it is apparently unrelated to VGA:
powerup iobase=1f0 st=50
powerup iobase=1f0 st=50
ata_detect ataid=0 sc=55 sn=aa dh=a0
The first time, st=0.
Thanks,
Myles
