indication a problem with system hardware.

 

 

Checking

BIOS could not write to the NVRAM block. This message appears when the FLASH

NVRAM..Update

part is write-protected or if there is no FLASH part (System uses a PROM or

Failed

EPROM).

 

 

Microcode Error

BIOS could not find or load the CPU Microcode Update to the CPU. This message

 

only applies to INTEL CPUs. The message is most likely to appear when a brand

 

new CPU is installed in a mainboard with an outdated BIOS. In this case, the BIOS

 

must be updated to include the Microcode Update for the new CPU.

 

 

NVRAM Checksum

There was an error in while validating the NVRAM data. This causes POST to clear

Bad, NVRAM

the NVRAM data.

Cleared

 

 

 

Resource Conflict

More than one system device is trying to use the same non-shareable resources

 

(Memory or I/O).

 

 

NVRAM Ignored

The NVRAM data used to store Plug’n’Play (PnP) data was not used for system

 

configuration in POST.

 

 

NVRAM Bad

The NVRAM data used to store Plug’n’Play (PnP) data was not used for system

 

configuration in POST due to a data error.

 

 

Static Resource

Two or more Static Devices are trying to use the same resource space (usually

Conflict

Memory or I/O).

 

 

PCI I/O conflict

A PCI adapter generated an I/O resource conflict when configured by BIOS POST.

 

 

PCI ROM conflict

A PCI adapter generated an I/O resource conflict when configured by BIOS POST.

 

 

PCI IRQ conflict

A PCI adapter generated an I/O resource conflict when configured by BIOS POST.

 

 

PCI IRQ routing table

BIOS POST (DIM code) found a PCI device in the system but was unable to figure

error

out how to route an IRQ to the device. Usually this error is causing by an

 

incomplete description of the PCI Interrupt Routing of the system.

 

 

Timer Error

Indicates an error while programming the count register of channel 2 of the 8254

 

timer. This may indicate a problem with system hardware.

 

 

Refresh timer test

BIOS POST found that the refresh timer hardware failed to pass the Refresh
