    Post a link to the BIOS file. If it's a Phoenix BIOS, it should be pretty easy to cut the 1024kB ROM out of it.

    Perhaps the BIOS does not know how to access the CMOS? Have you already reset the BIOS to setup defaults?

    Also even when you get that error message, does the BIOS finish POST and try to boot off a floppy, CD/DVD or hard drive? What I'm wondering is if you could do the normal crash recovery now with the full BIOS with the platform data.

    Thank you for your prompt answer.
    I actually tried to look inside my file with an hex editor but it seems somehow compressed (checked file BIO0076T.COM in double archive)

    If maybe you could have a look at it, that would be really nice :)

    Model: Toshiba Tecra S11

    Sorry, it appears that no one has cracked the Toshiba COM format yet.
