Int 13 Fn 06 - Future Domain Scsi BIOS - Format Drive With Bad Sector Ma [d]
AH = 06h
AL = interleave
(0 = default, 1 = consecutive sectors, 2 - 255 = vendor unique)
DL = hard drive ID
DH = bits 7-5 drive LUN
bit 4 defect list is available
bit 3 defect list is complete (erase drive's defect list)
bits 2-0 defect table format
(000=use defect table A, 100=use defect table B,
101=use defect table C)
ES:BX -> defect table A, B or C (see below)
Return: CF set on error
AH = status code (see AH=01h)
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)
