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).
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new CPU is installed in a motherboard with an outdated BIOS. In this case, the
BIOS must be updated to include the Microcode Update for the new CPU.
There was an error in while validating the NVRAM data. This causes POST to clear
the NVRAM data.
More than one system device is trying to use the same non-shareable resources
(Memory or I/O).
The NVRAM data used to store Plug'n'Play (PnP) data was not used for system

Two or more Static Devices are trying to use the same resource space (usually
Memory or I/O).
A PCI adapter generated an I/O resource conflict when configured by BIOS POST.
A PCI adapter generated an I/O resource conflict when configured by BIOS POST.
A PCI adapter generated an I/O resource conflict when configured by BIOS POST.
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.
Indicates an error while programming the count register of channel 2 of the 8254
timer. This may indicate a problem with system hardware.
BIOS POST found that the refresh timer hardware failed to pass the Refresh
Retrace Test.
BIOS POST could not initialize the Master Interrupt Controller. This may indicate a
