(... am I getting this right, flashrom uses the ISA bridge to write to flash part?)
Hi Roger,
thanks for your report.

Erase verification apparently worked.

Programming didn't return any immediate problems either.

Now it explodes. This is very strange.

That should have worked. Can you try to update to the very latest flashrom from svn and write the old image back? I hope that survives the verify. Please also send a log of the write attempt with latest flashrom from svn. Maybe it has some useful info.

Correct. On that board, the flash chip is attached to the ISA bridge. Later boards have a LPC bridge to which the flash chip is attached.

Yes. You are right. I was burning a coreboot image, and rebooting and coreboot seemed to execute without issues besides the usual stuff relevant to coreboot code.
I'll checkout svn flashrom sometime and post back my results. I also have to re-enter this fat thing into the motherboard rom again. :-/ (zif is too tight of a fit and usb pic programmers cost way too much.)

Ah. Thanks for helping to demystify this stuff for me.
