BC 7300 Series On-Board
Symbios SCSI Adapter
SCSI Device Installation
The board is equipped with an integrated Ultra Fast/Wide SCSI adapter. This adapter is enabled or disabled via the Chipset option of the BIOS Setup utility and via a hardware jumper (see the Quick Reference Guide for jumper settings).
The SCSI adapter is a bus master device which gains control of the PCI bus to transfer data between the CPU memory and the SCSI devices. The I/0 base address and interrupts are set by the PCI plug and play BIOS at boot time.
A SCSI configuration utility is available on boot-up of the board. Shortly after the SCSI BIOS information displays, the configuration program can be accessed by pressing Control C. The configuration utility will allow you to scan the SCSI bus, change configuration options, and view a list of SCSI devices connected to the board.
Termination
Figure 3-1, Terminating Internal SCSI Devices
SCSI termination is enabled on the board by installing a jumper on JP7. The SCSI connector (J18) is then configured as one end of the SCSI chain.
The last device on the SCSI cable must also supply a termination load to the cable. SCSI devices not at the end of the cable must have their termination loads disconnected.
Figure 3-2, Terminating Internal and External SCSI Devices
SCSI termination is disabled on the board by removing the jumper on JP7.
The last device on each end of the SCSI cable must also supply a termination load to the cable. SCSI devices not at the end of the cable must have their termination loads disconnected.
Note: Enabling and disabling a SCSI device's termination may involve a switch or shunt setting or the installation or removal of resistive SIP or DIP packages on their circuit board. Consult the installation manual for the SCSI device to determine its termination options.
