The Adaptec initialization routine may be executed by jumping to address
C800:CCC.  Depending on which controller you have, a 2002, 2010, or 2070
(the 2070 is RLL the 2002 and 2010 are MFM).

For the ACB-2002A or ACB-2010A:

Enter all numbers in HEX.

Step pulse rate: 3 with jumper A-B installed (13 us)

ECC correction span: should be 8

For the ACB-2070A:

Enter all numbers in decimal:

Step pulse rate: 3 (13 us)

I hope this helps, I can't figure out which controller you have from my
manuals as they only reference the 20xx numbers.

Good luck, Steve
