For Tomcat IV (or S1564D) boards the only choices are versions 1.0 (or
1.01 which only differs by a single spelling correction of one message)
and 1.02. The former one does not set up the onboard parallel port
correctly. The latter one breaks the MP-table. It also refuses to boot
from devices containing no DOS-compatible partition table even though
partitioning was never part of BIOS even back to the original PC/AT.
We may be able to use OpenBIOS one day, but for now I just know to avoid
Tyan like hell.
