Hi 

  We recently purchased a 386 machine with hopes of running the sco
xenix-386 on it. It turned out that the 386 chip inside was one of the
early Intel 386 chips that had the "16 bit S/W Only" stamp on it. I
believe this was because of a 32-bit multiply problem or some other
bug in early designs of chips.

  I recently got a hold of another 386 chip that does not have the above
stamp on it. But it also lacks any other indication that the chip is indeed
a 32-bit chip (i.e. no EE or Double Sigma mark).

My question is now this: Is there a quick and easy way to test the
chip from DOS (without having to go through installation of xenix).
The system I am using comes with MSDOS 3.2, 80Meg HD, 80387 and 1Meg
Memory and is a 16MHz machine. Note that both processors, for obvious reasons
run DOS perfectly. But my objective is to ultimately buy and install sco xenix
386.

Any comments are appreciated. Please respond directly to

who would route the message to me.      Thanks,    B. Nadji
