NEC MH4500 - Manual (Page 117)

Solving Problems 5-15
T Reserve interrupts (IRQs) and/or memory addresses specifically for ISA
adapters. This prevents PCI cards from trying to use the same settings
ISA cards are using. Use the SSU to keep track of ISA adapter resources.
T 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.”

System, Extended, or Shadow memory) which failed the memory
test. Each 1 (one) in the map indicates a failed bit.
