I pushed it just a bit farther. I downloaded dmidecode.exe from http://www.bttr-software.de/ports/ and added it to my FreeDOS floppy. It probably help that FreeDOS supports long file names because dmidecode is 9 characters (8 being the normal DOS limit). The message is the same on the laptop: Open DMI pipe failed! But on my P4 ICH4 desktop, it works now. Also, after reading: http://www.flashrom.org/Laptops I am less enclined to try. I did install latest BIOS with Toshiba flash program... the file being 512.25Kb, which suggest a 128 bytes header to study... not feeling like trying.
