NEC MH4500 Bios User’s Information, Error and Status Messages, Bios Messages, Message Description

Reserve interrupts (IRQs) and/or memory addresses specifically for ISA adapters. This prevents PCI cards from trying to use the same settings

TISA cards are using. Use the SSU to keep track of ISA adapter resources.

Certain drivers may require interrupts that are not shared with other PCI drivers. The SSU 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

The following paragraphs describe the various screen messages 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 may also be logged to the Event Logging area.

Error and Status Messages

The “BIOS Messages” table is an alphabetic listing of error and status messages that the BIOS generates. The table also includes an explanation of each message. Many of the messages refer to the built in Setup program. For more information about Setup, see Chapter 3, “Configuring Your System.”
