IPL device system configuration has changed!

BIOS detects a change in the number of boot devices.

DMA-2 Error

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

DMA Controller Error

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

Checking NVRAM; Update Failed

BIOS could not write to the NVRAM block. This message appears when the FLASH is write-protected or if there is no FLASH (system uses a PROM or EPROM).

Microcode Error

This error message, indicating BIOS could not find or load the CPU Microcode Update to the CPU, only applies to INTEL CPUs. The message is most likely to appear when a new CPU is installed in a motherboard with an outdated BIOS.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 while validating the NVRAM data. This error causes POST to clear the NVRAM data.

Resource Conflict

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

Due to a data error, the NVRAM data used to store Plug 'n Play (PnP) data was not used for system configuration in POST.

Static Resource Conflict

Two or more Static Devices are trying to use the same resource space (usually Memory I/O).
