If you are a COMPAQ Deskpro 386 owner, a copy of the DOS program
"MULTEST" is available from your dealer or COMPAQ. Other 386 owners
should contact their dealer, the manufacturer, Intel, in that order.
The program actually appears to be a part of the Intel test suite
for the 386 but I may be wrong. The program is run on a cold 386
and will display whether or not the 32 bit multiply bug is present.
