At work we have one PC that keeps locking up.  The wierd thing is that it does
this only in some applications always and in others sometimes and in others not
at all.  When it does lock up, we cannot fix the problem with a CTRL-ALT-DEL or
a Reset - when we do this, we get the following message(after HARD reset (turn
off power) and before memory check)

8042 GATE - A20 ERROR
SYSTEM HALTED

Programs that make the computer hang include 123 R31 and CXI3278C (an IBM 3278
Emulator program)

In windows when it hangs (only on some programs) I will get a "dump" across the
top of the screen with (inbetween trash) words like CLOCK, AUX, TIMER, etc.

Does anyone know what might be the probem here?  And how can I fix it?

286-20 w/ 4MB ram
AMI BIOS (I can get the date if it is needed)

If more info about the computer is needed, I can get specifics.
