Nope ... "pcilib ... cannot find any working access method". I think my original dump's probably fine, there's just some relocation trickery going on which will have to wait for one of the devs.
Thanks for the suggestion of flashrom. The page you linked to is a nightmare, though ...

I've uploaded an archive with about 20 different EGA and VGA card BIOS, photos and some drivers and docs.

I've uploaded an archive with stuff for the "Vendex HeadStart Explorer" ... since I can't figure out how to map the ROM drive I'll have to leave that one for the experts.

I'm looking for the distribution floppies/CD 1 for the earlier Headstart with CD-ROM that ran PC-GEOS
I have a machine, but the previous owner put DOS on it.
I have the other CDs in the set and the manuals.

Recently, a hitherto unknown BIOS version for the Olivetti M21(M24) was seen in an Ebay auction, and it was dumped.

PR is up with my other PC stuff smile

I'll be starting on adding the online available 486 motherboards and their BIOS versions to at.cpp soon. One caveat that comes up in a few archives is that from certain revisions on the BIOS requires being put into a flash chip instead of EEPROM to perform "an ESCD update at boot that fails on write-only chips".
It would be great if we could have a 486 machine in at.cpp that has a memory map modified to suit that requirement.

Different flash chips have different commands, so that's not quite as simple as you'd like.

Good point, so it'd make sense to document the flash type along with the other mainboard information.

Cutest error message ever:

This is after adding the AEG Olympia Olyport 40-21 BIOS, it's a re-branded Zenith SuperSport 286 which expects some kind of ROM shadowing.
