* VARCem Virtual ARchaeological Computer EMulator.

* Implementation of the DTK PII-151B and PII-158B cards.
*
* These are DP8473-based floppy controller ISA cards for XT
* class systems, and allow usage of standard and high-density
* drives on them. They have their own BIOS which takes over
* from the standard system BIOS.
