The addresses and interrupts used by the external parallel port can be assigned in AMIBIOS Setup.
Refer to the System Setup for information to configure the ports. The parallel port addresses and
interrupts are shown in the following table.
Port Address Interrupt
LPT1 378-37A IRQ7 or IRQ5
LPT2 278-27A IRQ7 or IRQ5
LPT3 3BC-3BE IRQ7 or IRQ5
Processor Components
Processors
The system uses one or two processors installed on the system board. Each processor is 180 MHz or
200 MHz Pentium Pro with 512 MB secondary cache. Quad-processor systems use a processor card
(MSMT310) to add two more processors. When only one or two processors are installed, the P6 bus
termination card (MSMT311) is installed instead of the processor module. The termination card
provides bus termination for the P6 bus.
Processor Jumpers
Jumpers are used to set the processor to clock speed ratio for the system. The default, certified
configuration is a ratio of 3:1 (3x multiplier). The 180 MHz CPU uses a 60 MHz P6 bus, with jumpers
installed to obtain the 3x multiplier. The 200 MHz CPU uses a 66.67 MHz P6 bus, with jumpers
installed to obtain the 3x multiplier. The following table shows the jumper settings to obtain the 3x
multiplier. IN denotes the jumper is installed on both pins.
CPU 0 Frequency CPU 1 Frequency
Jumper Setting Jumper Setting
J63 OUT J49 IN
J62 IN J50 IN
J61 IN J47 IN
J60 IN J48 OUT
CAUTION Do not change the jumper settings in an attempt to change CPU speed. The CPUs will only operate
properly when the jumpers are installed in their default settings.
