ERROR MESSAGES PEVELOPED BY THE MEMORY TEST PROGRAM
The memory test program will report any errors discovered in the operation of
the tests. The errors will be reported in the following manner.
Memory error-Address:xxxx Expected value:xx Observed value:xx
The difference between the observed and the expected value will tell you which
bit is bad at the indicated address. Since the memory chips are all 1 bit wide,
this will also indicate which chip is bad.
If errors are displayed, the memory
board should be exchanged for another.
