System Configuration

DMA-1 Error

Error initializing primary DMA controller. This is a fatal error, often indication a 
problem with system hardware.

DMA-2 Error

Error initializing secondary DMA controller. This is a fatal error, often indication a 
problem with system hardware.

DMA Controller Error

POST error while trying to initialize the DMA controller. This is a fatal error, often 
indication a problem with system hardware.

Checking 
NVRAM..Update 
Failed

BIOS could not write to the NVRAM block. This message appears when the FLASH 
part is write-protected or if there is no FLASH part (System uses a PROM or 
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new CPU is installed in a mainboard with an outdated BIOS.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 
Bad, NVRAM 
Cleared

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

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 
Conflict

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

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

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

Interrupt Controller-1 
error

BIOS POST could not initialize the Master Interrupt Controller. This may indicate a 
problem with system hardware.

Interrupt Controller-2
error

BIOS POST could not initialize the Slave Interrupt Controller. This may
indicate a problem with system hardware.
