Message

Description

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

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new CPU is installed in a mainboard with an outdated BIOS.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.
