Future Domain SCSI BIOS - FORMAT DRIVE WITH BAD SECTOR MAPPING

AH = 06h
AL = interleave
(0 = default, 1 = consecutive sectors, 2 - 255 = vendor unique)
DL = hard drive ID
DH = defect list info (see #00237)
ES:BX -> defect table A, B or C (see #00238,#00239,#00240)

Return:
CF set on error CF clear if successful AH = status code (see #00234)

Notes: Block addresses must be in ascending order (for table B, cylinder is most significant, byte from index least significant; for table C, cylinder is most significant, sector number least significant). Table B defect bytes from index of FFFFFFFFh indicates that the entire track shall be reassigned. Table C defect sector number of FFFFFFFFh indicates that the entire track shall be reassigned. The TMC-950 does not support any Future Domain BIOS calls; instead, it provides a full CAM implementation (see INT 4F/AX=8100h)
