ca67ee41c5 Fix CBIOS Bug 
- Corrects the dynamic disk buffer allocation routine in CBIOS and ASSIGN.COM.  They had the DPB assignments inverted causing slightly wrong buffer allocations for RAM and ROM disks.

Credit to Andrew Lynch for discovering this issue.

1945c0f52d CBIOS default drive assignment cleanup 
Improved the way that the default drive is assigned in the scenario where you are booting to a ROM-based OS.  This should allow removal of either the RAM drive or the ROM drive without causing unexpected consequences.

Supports double-buffered disk i/o to read/write to/from any memory bank specified.

NOTE:  Disk I/O will be temporarily slower than normal because all I/O is being forced thru double-buffering for testing.
