ASPI Driver for DOS

This chapter describes the ASPI (Advanced SCSI Programming Interface) driver installation for DOS and some other useful utility programs under this ASPI environment:

1.The ASPI driver, ASPIBME.SYS, provides the basic communication interface for the host adapter device driver and DOS operating system. It supports up to six coexisting host adapters, and the ASPI interface for Sytos (Plus), ARCserve/Solo tape subsystems, fixed disk, removable cartridge, MO, Floptical, CD-ROM, CD-Changer and scanner.

2.The DISKDRV.SYS is for installing valid DOS partitions as logical drives with those SCSI devices not controlled by BIOS INT 13H. It supports Fixed disk, Removable Cartridge, Re-writable Optical Disk (MO) and Floptical. It also enables you to recognize data formats used by other adapter manufacturers.

3.TFDISK.EXE is a DOS compatible disk partition utility program. It allows you to choose several popular translation modes to port your DC- 820B partition to other manufacturers’ adapters. This provides you great flexibility for drive portability to other adapters.

4.CHKDRIVE.EXE is a utility for checking the physical drive and its logical status.

5.ASPICD.EXE is the device driver for CD-ROM and CD-Changer devices.

DOS uses the ASPI driver as a software interface to communicate with SCSI devices. The peripheral driver will talk to ASPI interface instead of host adapter hardware. Under this architecture, multiple devices can share the host adapter without conflict. The ASPI driver is typically installed under the following situations:

nMultiple adapters coexist (up to six)

nSCSI devices not controlled by BIOS INT 13H n install removable media

n interface to Tape, CD-ROM and other SCSI devices
