Incorrect drive A type - run SETUP

The diskette drive is not correctly specified in BIOS Setup.

Invalid NVRAM media type

Problem with NVRAM (non-volatile random-access memory).

Keyboard error [nn] or Keyboard controller error

There is a problem with the keyboard or (less likely) the standard I/O controller on the motherboard. If POST discovers a stuck key it displays its scan code.

Operating system not found

An operating system cannot be located either on a system diskette or on a hard disk. Start BIOS Setup and check that the diskette and/or hard disk drives are specified correctly.

Parity check 1 xxxx or Parity check 2 xxxx

Parity error found on the system (1) or I/O (2) bus. The BIOS attempts to locate and display the address xxxx. If it cannot locate the address, it displays “????”.

Previous boot incomplete - default configuration used

The previous POST did not complete successfully. POST loads default values and offers to start BIOS Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail too.

Real-time clock error

Enter BIOS setup and check the System Time and System

Date settings on the Main menu.

System battery is dead - replace and run Setup

Replace the configuration battery as instructed in the

Motherboard Features & Upgrades chapter, then use BIOS

Setup to reconfigure the system.

System cache error - cache disabled

The RAM cache failed POST and BIOS disabled it.

System CMOS checksum bad - run Setup

System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOS. Run BIOS Setup and reconfigure the system either by getting the default values or by making your own selections.
