PCI-946-1 and P3S440BX Technical Reference manual
2.7.3. SCSI Devices
The board supports PCI Ultra Fast/Wide SCSI 3 with operation up to 40 MB/s and data
bursts to the host at full PCI speeds, Fast and Ultra SCSI 2 Adaptec AIC 7880.
The PCI Wide-Ultra SCSI 3 port is available at J4. A wide SCSI cable, 68-pin male to 68-
pin male is supplied with the PCI-946 (part number 150-371-00).
You can access the PCI Fast and Ultra SCSI 2 through J3 using a 50 pin SCSI cable. This
cable is supplied with the PCI-946 (part number 150-183).

2.7.3.1. SCSI activity monitoring
The SCSI activity status signal is available through J2 (2-pin lock header). Connect the
LED as follows: anode (red lead) on pin 1 and cathode (black lead) on pin 2. No external
current limiting resistor is required since it is already present on the board (330 ohm resistor).
50-pin Fast SCSI and Fast-20 SCSI devices are also supported using a 68-pin to 50-pin
adapter cable.

Setup is described in Section 4.1.10 – AWARD CMOS Setup Utility, Integrated
Peripherals option
The onboard SCSI interface is enabled by default.
To change setups, see Section 4.1.10 AWARD CMOS Setup Utility, Integrated
Peripherals option
NOTE
Ensure that the onboard SCSI controller is enabled in the AWARD CMOS
Setup Utility, Integrated Peripherals.
The Adaptec SCSISelect configuration software is provided with the board
to configure or view the default SCSI settings of the host adapter (See Section 7
Configuring SCSI). It replaces the <Ctrl-A> feature on standard Adaptec
controllers
The EZ-SCSI software is provided with the board to install the appropriate
driver for your specific operating system.
