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 COM1/
COM2 ports, 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

Etc…

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

IRQ#

Description

IRQ #0

System Timer

IRQ #1

Keyboard Event

IRQ #2

Usable IRQ

IRQ #3

COM2

IRQ #4

COM1

IRQ #5

Usable IRQ

IRQ #6

Diskette Event

IRQ #7

Usable IRQ

IRQ #8

Real-Time Clock

IRQ #9

Usable IRQ

IRQ #10

Usable IRQ

IRQ #11

Usable IRQ

IRQ #12

IBM Mouse Event

IRQ #13

Coprocessor Error

IRQ #14

Hard Disk Event

IRQ #15

Usable IRQ

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.
