[net.micro.pc] PC AT BIOS

gary@catnip.UUCP (Gary Quiring) (04/10/86)

I have several patches for AMI AT BIOS.  I would like to save the bios
out to disk using debug but I don't know where the bios resides in memory.
I think it's at F800:E000 - FFFF but I'm not a hardware guru.

        I don't know what the AMI AT is, but if it's the usual AT
        (NOT XT) clone with a 32k BIOS that doesn't include any
        BASIC, then something like F800:0000-7FFF or
        F000:8000-FFFF should do the trick.  The address range
        that you mention is not possible in real mode.
