Micronics M5Pi System Board Manual
4-6
Serial Port B
Serial Port 2 may be set for COM2 (default), COM4, or may be disabled. Be
sure this setting does not conflict with any other peripherals.
Parallel Port
The parallel port may be set for LPT1 (default), LPT2, or may be disabled. Be
sure this setting does not conflict with any other peripherals.
Secondary IDE
The ISA IDE controller can be set to ENABLED or DISABLED.
Onboard Floppy
The On Board Floppy controller can be set to ENABLED or DISABLED.
Swap Floppies
This category can be set to remap the floppy drives. It can be set for NOR-
MAL (default) or SWAPPED. For normal operation, Drive A: and Drive B:
work normally. When “Swapped” is selected, Drive A: becomes Drive B:, and
Drive B: becomes Drive A:.
Boot Sequence
This category selects the order the system searches for a boot disk and can be
set for “A: First” or “C: First.”
Cache State
This category allows you to enable both the internal and the external cache,
enable the internal cache only, or disable both caches. For optimal perfor-
mance, select BOTH.
Note:
External cache must be installed in order to select BOTH.
1st PCI Device
This selection allows you to set the IRQ of the 1st PCI device to IRQ9, IRQ11,
or IRQ15. The next IRQ will automatically be assigned to the next peripheral.
(eg. If slot 0 is empty, slot 1 has a SCSI controller, and slot 2 has a network
card, setting 1st PCI Device for IRQ9 will assign the SCSI controller to IRQ9
and the network card to IRQ11.)
Note:
Not all PCI peripherals require an IRQ and most video cards do not. Even if
slot 0 had a video card installed in the above example, the system would still
assign IRQ9 to the SCSI controller.
