PC Test Card

LED:

The green LED on the PC test

card lights

when

the PCMCIA test is running. If the LED

does not light, check that the card is installed correctly by

reseating

the card. If it still does not light after reseating,

try using

another

slot for the test. If the LED still does not

light and the test fails, replace the FRU shown in the

diagnostic

error

code.

Errors

during

the

POST:

 

If the POST detects an

 

 

 

error,

a

three- to

eight-digit error

code

displays.

Memory Errors:

 

If

 

the

POST detects

a memory

error

in the first 640 KB

 

of system

memory,

all

the

first bank

memory

is

deallocated

and

the

test continues

with

the

second

640

KB of memory. If the total amount of

 

error-free

memory becomes less than 2

MB,

a

2XX

POST

error occurs and the system stops. All

the

remaining

memory

is

used

as

system

memory. When

the

POST

 

 

memory test has completed, the usable memory size is compared with the configuration data. If a mismatch is detected, a 2XX error code Escoccurs,and.F1Press

after restart to continue system operation.

Memory sizes, that are deallocated because of the POST

process,

are

kept by the hibernation or suspend functions.

To

test

this

memory, it must

be

reconfigured as part of the

original

memory

size. Configure

by

turning the power off

and

on.

 

 

 

 

Deallocation support is done only by the POST for memory errors. All irrecoverable memory errors that occur during normal operation cause an interrupt to the operating system.
