Low-Level PC Formatting Using Debug Commands

I just ran across this and thought it might be of interest for anyone doing a low level format on a PC (not AT) type controllers. It was taken from a February 13, 1989 issue of Tech Times that appears to be a ComputerLand Confidential publication (this is a copy.) My usual procedure was to unassemble C800:5 or C800:6 and G=????:? the address that was a jmp instruction. I've never used the :800 or tried to format a Xebec controller. ******************* Company Debug Command Adaptec -G=C800:CCC DTC -G=C800:5 Omti -G=C800:6 Western Digital -G=C800:5 or -G=c800:800 Xebec Series of commands -l322 -l321 -o322 0 -l321 -o320 04 -0320 00 -o320 00 -0320 00 -0320 05 -0320 07 (use 17 if embedded servo dr) At this point, the LED on the drive should come on to indicate that the drive is formatting. When the light goes off, coninue: -l321 -l320 The last entry should get 00 status back, indicating a successful format.
