Solution
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motherboard with an outdated BIOS.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 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 configuration in POST.
The NVRAM data used to store Plug'n'Play (PnP) data was
not used for system configuration in POST due to a data error.
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 caused 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 problem with system hardware.
BIOS POST could not initialize the Slave Interrupt Controller.
This may indicate a problem with system hardware.
The CMOS Date and/or Time are invalid. This error can be
resolved by readjusting the system time in AMIBIOS Setup.
CMOS Battery is low. This message usually indicates that the
CMOS battery needs to be replaced. It could also appear when
the user intentionally discharges the CMOS battery.
