[comp.sys.ibm.pc] Error on IBM PC self-test

jlu@mrevox.UUCP (01/15/88)

-->One of the secretaries in our office can't get her PC going. When she
-->turns on the computer, it goes through its usual self-test. Then the
-->screen displays 
-->
-->"2020 201"
-->
-->in the upper corner for about .5 sec, and the clears and displays
-->
-->"Parity Check 1"
-->
-->indefinitely. The disk drive also coughs for about .5 sec. She can't
-->get any disks to boot, not even Diagnostics.
-->
-->Any Clues? I'd GREATLY appreciate some. My supervisor is getting kinda
-->tired of increasing maintenance/repair costs that my office is building up.

This sounds like the memory check test.  Does it do this after going through
all the memory?

201 is the memory test failure number, and 2020 is the chip number.  If memory
serves, that's row 2, bit 5.
