If the MMIO space regions of the video cards sit right before the

convince me that this is the kind of problem we are having here.
Unfortunately, looking at the lspci outputs that are in
https://bugzilla.novell.com/show_bug.cgi?id=425480 it seems to me that the
MMIO regions are quite far away from each other.
on my ich9 based system the e1000e BAR1 regions are back to back with
both the vga memory map and the audio mem, either of which could be the
mangler, but more likely vga device (say X maybe) since it is mapped
directly in front of the e1000e BAR1 space.
Yup on my laptop these were far away and I wondered what could mangle
things that badly.
Well I'm out of the race, my attempts to re-write my eeprom using an
eeprom from an equivalent laptop
have totally failed and my BIOS won't boot anymore - so my laptop is == a brick.
I'm really sorry to hear that, I wonder if the laptop has an "emergency
bios update" mode like many PCs used to through a jumper. Dave A., let
us know if you make any recovery progress.
I plan to try some random writes tomorrow to my BAR1 space and see if my
flash gets erased.
