SCSI Feature

The system board features a single-chip Fast SCSI-2 host adapter that adds
SCSI I/O capability to the system. The device consists of all the components
found on the state-of-the-art SCSI host adapters such as an onboard
microcontroller, bus master interface controller, and SCSI controllers. In EISA
mode, this device can transfer at a full 33 MB/second burst transfer rate.
2.4.1

Using SCSI

There are four points to remember when using the SCSI feature of your system.
1. Open jumpers JP1 and JP2.
2. Set jumper JP8 to pins 2-3 to select IRQ11. Refer to the list of jumpers
at the end of this chapter.
NOTE:
3. Use the SCSI connector CN1 before CN3.
CN3 does not work if CN1 is not used.
4. When installing the SCSI drivers in the EISA Configuration Utility (ECU),
the option "Extended translation for device > 1 GByte" under BIOS
Configuration, should be set to Enable for fixed disks with greater than
1 Gbyte capacity in DOS environment. Set it to Disable for other software
environments.
NOTE:
In this system, you can select only IRQ10 or IRQ11.
For best system performance, use IRQ11.
Refer to the SCSI manual for more information.
