INT 13 - Future Domain SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer. A host adapter connects the SCSI bus to the computer's own bus. See also ESDI, IDE. CONTROLLER - GET SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer. A host adapter connects the SCSI bus to the computer's own bus. See also ESDI, IDE. PARTIAL MEDIUM CAPACITY
AH = 1Ah
CH = track (bits 8,9 in high bits of CL)
CL = sector (01h to number of sectors/track for drive)
DH = head
DL = hard drive ID
Return: CF set on error
AH = status code (see #00234 at AH=01h)
CX:DX = logical block number of last quickly-accessible block after
given block
Notes: sends SCSI(Small Computer Systems Interface) A system-independent expansion bus typically used to connect hard disks, tape drives, and CD-ROMs to a computer. A host adapter connects the SCSI bus to the computer's own bus. See also ESDI, IDE. Read Capacity command with the PMI bit set to obtain the
logical block address of the last block after which a substantial
delay in data transfer will be encountered (usually the last block
on the current cylinder). No translation to 512 byte sectors is
performed on the result if data is stored on the disk in other than
512 byte sectors.
the TMC-950 does not support any Future Domain BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. calls; instead,
it provides a full CAM implementation (see INT 4F/AX=8100h)
