CSSCSI.SYS

The IBM PCMCIA SCSI card comes with device driver CSSCSI.SYS, which is the card services enabler. After card services and socket services are loaded CSSCSI.SYS activates the card upon insertion. The actual SCSI adapter device driver, FD16-700.ADD, will now be able to detect an SCSI adapter and load successfully during the boot process.

BASEDEV=CSSCSI.SYS IO=x IRQ=y

Parameters

CSSCSI.SYS is installed using a BASEDEV= statement in the CONFIG.SYS file and has two parameters:

IO=x

where x can be either port address 140 or 170

IRQ=y

where y can be interrupts 3, 5, 10, 11, 12, 14, or 15

The device driver CSSCSI.SYS supports two PCMCIA SCSI cards in one machine and allows you to specify two parameters for each card. The driver accepts an 10 port address and Interrupt Request channel for each card. If you specify parameters for two cards separate them with a comma. Please refer to the example below:

BASEDEV=CSSCSI.SYS IO=140 IRQ=5, IRQ=11 

In the above example the first SCSI card would be assigned 10 address port 0x140 and Interrupt Request Channel 5, and the second SCSI card would be assigned the default 10 address port 0x170 with Interrupt Request Channel 11. If no parameters are specified in addition to the device driver, the default assignments are 10=140 IRQ=5, and 10=170 IRQ= 11, respectively.
