8.1Built-In Self Test

The FFD performs a self-test during power up. If the test fails, the green LED flashes at a rate of 1 Hz. If you encounter this problem, please contact your dealer or technical support.

8.2Common Problems

The following sections describe common problems and their causes.

8.2.1Installing Your SCSI Host Adapter

A SCSI host adapter is basically a standard PC board, regardless of the bus system used. For example:

To install a standard Adaptec 1542CF:

1.Check the default values of the board and verify that they do not conflict with other devices in the PC.

2.Check the I/O-address range, the IRQ(s), DMA channel, and the BIOS address for conflicts. When using a memory manager, exclude the selected BIOS address space from its memory pool. When selecting all resources, enter them in your list of resources.

3.Install the host adapter in the PC and power it ON. If you did not un-install the BIOS, a BIOS boot message similar to the following is displayed:

Adaptec AHA-2940 Ultra/Ultra W BIOS v1.23

<<< Press <Ctrl> <A> for SCSI Select (TM) Utility >>>

SCSI ID: LUN NUMBER #:# 0:0 – DEC DSP3085S-B SD16 – Drive C: (80h)

SCSI ID: LUN NUMBER #:# 1:0 – M-Systems FFD 350/FMAX 5D – Drive D: (81h)

The boot-up message lists all devices on the SCSI bus that are powered ON. Additionally, it indicates if any of the devices are disks that are supported by the BIOS.

4.Power OFF the PC and install the SCSI device(s). If you have more than one internal device:

•Set up a unique SCSI ID (not 7) on each of the devices.

•Select one of these devices to be at the end of the cable.

5.Make sure that the chosen device has its termination enabled and disable termination on all other devices. Termination is either enabled through one or more jumpers, or by installing or removing some resistor packs on the device’s PCB.
