Warning Messages - Digital Equipment HiNote VP 500 Series Service Manual

If the BIOS detects error 2C, 2E, or 30 (base 64K RAM error), it displays an additional word
of information reflecting the bit or address line that failed. For example, if "2C 0002" is
displayed, address line 1 (represented by bit one) has failed. If "2E 1020" is displayed, then
data bits 12 and 5 have failed in the upper 16 bits.
The BIOS sends the same information to the port 80h LED display. The check point code is
followed by a delay, the high order byte, another delay, and then the low order byte of the
error. This is be repeated continuously.

Description
nnnn is the amount of system cache in kilobytes
successfully tested.
Drive A: is present but fails the BIOS POST diskette
tests. Check to see that the drive is defined with the
proper diskette type in Setup and that the diskette
drive is attached correctly.
Starting Setup program
Extended memory not working or not configured
properly.
nnnn is the amount of RAM in kilobytes successfully
tested.
The hex number nnnn is a map of the bits at the
RAM address (in System, Extended, or Shadow
memory) which failed the memory test. Each 1 (one)
in the map indicates a failed bit.
Fixed disk is not working or not configured properly.
Check to see if fixed disk is attached properly. Run
Setup to ensure that the fixed-disk type is correctly
identified.
Type of floppy drive A: not correctly identified in
Setup.
Problem with NVRAM access.
The keyboard controller failed test. You may have to
replace keyboard or controller.
Keyboard not working.
BIOS discovered a stuck key and displays the scan
code for the stuck key.
Unlock the system to proceed.
Run SETUP Monitor type not correctly identified in
Setup
Operating system cannot be located on either drive
A: or drive C:. Enter Setup and see if fixed disk and
drive A: are properly identified.
BIOS attempts to locate the address but failed and
display it on the screen.
