IOW it's just a ROM-based BIOS extension.  I _want_ one of
those.  And having such a card around for other ROM firmware
extension purposes would be cool, too.  Unfortunately the ROM
contents is copyrighted, because otherwise that BIOS extension
upgrade would eliminate the need for the awful kludges like Disk
Manager on a lot of older systems.
