Intel has admitted to a problem with incorrect results on some multiply
combinations in native 32-bit mode. These problems will not surface
running msdos or '286 unix/xenix on your 80386, but they *could* appear
when running an 80386 operating system.

Yes, Xenix *and* unix are running on the 80386. Microport Systems Inc of
Scotts Valley Ca is taking orders for a full 80386 version of SV3 that is
to be delivered in July. Rumor has it that they are currently getting
SVID ok from AT&T. The price is supposed to be around $800 for the software
development kit, the text preparation kit, and the runtime system.

The recent large posting of Dhrystone benchmarks listed several entries
for Xenix 386 (also SV3) running on Multibus equipment. While I haven't
seen any non-beta/end-user sites running either of these systems, I HOPE
it is only a matter of time until anyone who has a 80386 can start actually
using the other 50% of the silicon that until now has gone to waste
emulating lesser chips.
