[ATI widescreen model]
After a failed bios update this thing comes up with that t***er error,
flashing coreboot gets it running (booting usb/ssh into the machine).
However, none of the 1002,7145 vgabios option roms (there a two in the
original bios) gets either LVDS or VGA running.
To make a long story short, I'm looking for a T60/ATI coreboot image
which works _or_ a so called 'dirty' vga-bios extracted from ram
(apparently the bios 'patches' some variables on startup).
Since it won't boot I can't get it out of this machine and my other T60
is a 4:3 intel graphics :-(
Hints welcome, regards

(retrieval via kernel or extracting from mem)
they describe various methods of extracting, maybe one will work with
your machine.
Any help appreciated

Got my hands on another machine with a X1300 chipset, extracted the vga
bios from ram, changed the pci id to match X1400 (basically the same
bios code), stuck it into coreboot, told seabios to ignore the checksum.
Hey, presto it's alive again :-)
