Hi admkukuh, thanks for your report. It was stuck in the moderation queue because of the big images (not suited for a mailing list). Hence, I'm forwarding it without the images. It's amazing to see that the DOS port still works :) Did you also have to modify the stock BIOS to enable flashprog to read? Or was it only necessary to write? We could add a DEP (depends) entry to our list of known boards, I guess.
