* drive offsets (this is in GROUPS OF 256 SECTORS!)
* can be used to logically partition 1 physical drive into up to
* 4 logical drives.
* I always use a least an offset of 1 to allow for possible os9 boot
* track on the drive, also if it's a used PC drive, the first few
* cyls are where all the errors are :-)

* note the name here. DI1024, DIS512 and DI256 are DISTO DRIVERS of various
* sector sizes. TC1024, TCC512 and TCCCHD are the equivalents for the TC3 host
* adapter. DBHSHD for 256 byte/sector st506 style external controllers which
* require handshaking on each byte of a data transfer (i.e. adaptec). DIDBHS
* for the same thing with a DISTO host adapter.
