5-14 Problem Solving
Plug and Play Installation Tips
Some common PCI tips are listed here.
!
Reserve interrupts (IRQs) and/or memory addresses specifically for an ISA adapter.
This prevents PCI cards from trying to use the same settings an ISA card is using.
Use the BIOS Setup Utility to keep track of ISA adapter resources.
!
Certain drivers may require interrupts that are not shared with other PCI drivers.
The BIOS Setup Utility can be used to adjust the interrupt numbers for PCI devices.
For certain drivers, it may be necessary to alter settings so that interrupts are not
shared.
BIOS User’s Information
This section describes the various screen messages and beep codes of the system BIOS.
The BIOS indicates errors by writing an error code to the PS/2-standard logging area in
the Extended BIOS Data Area, and by displaying a message on the screen, which is
sometimes preceded by the POST Error Code. The error code will also be logged to the
Event Logging area.
Note:
Your system error log will be lost, if your system ac power
source is off or disconnected.
POST Error Codes and Messages
Whenever a recoverable error occurs during POST, BIOS displays a message on the
video display screen and causes the speaker to beep as the message appears. BIOS also
issues a beep code (one long tone followed by two short tones) during POST if the
video configuration fails or if an external ROM module does not a checksum of zero.
The “POST Error Codes and Messages” table is a list of the error codes and messages
written at the start of each POST test. The “POST Error Beep Codes” table is a list of
beep codes issued for each POST test.
