Michael, Re: I would call it a shortened virus code

In the Wintel world, you are right. But this 'bug' turn
all Linux/FreeBSD useless. It would hit small ISPs
running these decent OS. I believe they have reason
to ask Intel for refund or upgrade coupon(to PII) if they
are running Pentium.

ALL multiuser Unix systems running on Intel Pentium (including MMX) processors are vulnerable to the 'F0' bug. Any user can bring down the entire multiuser system by typing a few lines on his terminal.

To say this is not a bug is to say the sun revolves around the earth -- true only from an Intel-centric point of view. The whole idea of having a "user mode" in a CPU is so that the operating system can maintain control at all times. If a new CPU came out with an instruction set that allowed a HALT instruction in user mode, NOONE would buy it, it is a totally useless CPU. The F0 0F C7 C8 opcode is a halt intruction which Intel forgot to document in their specification.

How long do you suppose AMD can go on losing millions quarter after quarter??

With a net worth over 2 BILLION dollars, quite a while yet. Save yourself some aggravation and sell Intel now. You can get it back in the sixties.
