Improper disable operation

There are too many occasions where users disable a certain device/feature in one
application through BIOS setting. These variables may not be set back to the original
values when needed. These devices/features will certainly fail to be detected.

When the above conditions happen, it is strongly recommended to check the BIOS
settings. Make sure certain items are set as they should be. These include the floppy
drive, COM1/COM2 ports, Parallel port, USB ports, external cache, on-board VGA
and Ethernet.

It is also very common that users would like to disable a certain device/port to
release IRQ resource. A few good examples are

Disable COM1 serial port to release IRQ #4
Disable COM2 serial port to release IRQ #3
Disable Parallel port to release IRQ #7
Disable PS/2 mouse to release IRQ #12,
Etc…

A quick review of the basic IRQ mapping is given below for your reference.

IRQ#

Description

IRQ #0

System Timer

IRQ #1

Keyboard

IRQ #2

Unassigned

IRQ #3

COM2

IRQ #4

COM1

IRQ #5

ATI VGA Controller

IRQ #6

Floppy Disk Controller

IRQ #7

Parallel port

IRQ #8

Real-time Clock

IRQ #9

Microsoft ACPI-Compliant System

IRQ #10

Network Controller

IRQ #11

Network Controller

IRQ #12

PS/2 mouse

IRQ #13

Data Processor

IRQ #14

Primary IDE Controller

IRQ #15

Secondary IDE Controller

It is then very easy to find out which IRQ resource is ready for additional
peripherals. If IRQ resource is not enough, please disable some devices listed above
to release further IRQ numbers.
