System Board

This high-performance system board supports both the 486-series
and the Intel Pentium
the CPU and the second-level cache. Instead, it accommodates a
separate board that carries both the CPU and the second-level cache.
This feature allows maximum upgradability and flexibility.
The board features the single-chip upgrade technology that makes
CPU upgrades easy and economical, and also the multiple-CPU
upgrade technology that can convert your machine into a
multiprocessor system. These innovative technologies protect your
investment well into the future.
Standard features such as two serial ports, one parallel port, a
diskette drive interface, and an embedded fixed disk drive interface
reside on the system board.
The system board has a 8/16-MB base memory and supports a
maximum memory of 128 MB using 32-MB SIMMs. When you install
the dual-Pentium (3.3V) CPU board, you get four additional SIMM
sockets for a total system memory of 256 MB using 32-MB SIMMs.
When you install the Pentium (3.3V-ECC) CPU board, you get two
additional SIMM sockets that support a maximum memory of 64 MB
using 32-MB SIMMs, for a total system memory of 192 MB.

Follow these steps to install a SIMM: Slip a SIMM at a 45 angle into a socket with the component side facing down. Gently push the SIMM to a vertical position until the pegs of the socket slip into the holes on the SIMM, and the holding clips lock the SIMM into position.

    SCSI Feature The system board features a single-chip SCSI host adapter that adds SCSI I/O capability to the system. The chipset consists of an onboard microcontroller, bus master interface controller, and SCSI controllers. A 50-pin Fast SCSI-2 interface with 10 MB/s transfer rate and a 68- pin Wide SCSI interface that transfers at 20 MB/s also come with the board to accommodate the SCSI devices.

    Jumper Settings You have to change the jumper settings on the system board when you upgrade the CPU or reconfigure the system. Follow these steps to change a jumper setting: Remove the jumper cap from the jumper. Position the jumper cap over the two pins for the desired setting. Gently press the cap over the pins.

  • Page 16 1.6.3 Correcting Error Conditions As a general rule, if an error message says "Press F1 to continue," it is caused by a configuration problem, which can be easily corrected. An equipment malfunction is more likely to cause a fatal error, i.e., an error that causes complete system failure.
