Solution
8504: 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
motherboard with an outdated BIOS. In this case, the BIOS
must be updated to include the Microcode Update for the new
CPU.
8505: NVRAM

NVRAM Cleared
There was an error while validating the NVRAM data. This
causes POST to clear the NVRAM data.
8506: Resource
Conflict
More than one system device is trying to use the same
non-shareable resources (Memory or I/O).
8507: NVRAM
Ignored
The NVRAM data used to store Plug’n’Play (PnP) data was
not used for system configuration in POST.
8508: 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.

Usually this error is caused by an incomplete description of the
PCI Interrupt Routing of the system.

The CMOS Date and/or Time are invalid. This error can be
resolved by readjusting the system time in AMIBIOS Setup.
