It will only be compatible with the older BIOSes for the A: drive. The rest
has to be calculated by multiplying the drive with 16 instead of 8, so if
you read the DIB of drive B:, one way or another, it will always give the
incorrect result if you use an older BIOS.
But now I see why it's not a good idea to combine the updates. I didn't know
the 'media-ID' was a required setting...
