Table 95. Memory BIOS Messages

The BIOS is unable to properly control the motherboard's
Gate A20 function, which controls access of memory
over 1 MB. This may indicate a problem with the
motherboard.
This message will only occur on systems using ECC
enabled memory modules. ECC memory has the ability
to correct single-bit errors that may occur from faulty
memory modules.
A multiple bit corruption of memory has occurred, and the
ECC memory algorithm cannot correct it. This may
indicate a defective memory module.
Fatal Memory Parity Error. System halts after displaying
this message.

This is a generic message indicating the BIOS could not
boot from a particular device. This message is usually
followed by other information concerning the device.
A diskette was found in the drive, but it is not configured
as a bootable diskette.
The BIOS was unable to access the drive because it
indicated it was not ready for data transfer. This is often
reported by drives when no media is present.
The BIOS attempted to configure the A: drive during
