I have a 386 motherboard from the dawn of time sitting here , 8 MEG ram ,
385meg HD (split between SCSI and ST506/Perstore) with VGA and so on.

I like the system, and recently got a free 80287 to put on it ...

Yes, 80287! This motherboard is from a million years ago and has no 80387
socket. So , on the '287 goes.

Does anyone know if the ISC kernel will find and use it ? Is there a
DIFINITIVE way to tell if it has found it , and to test for future errors
(like, if it emulates 3 of 4 instructions, will the FPU emulator get the
last one or will my system halt ...)

The guy at ISC had no idea at all, and Intel says that is a valid, supportd
hardware combination that they had pushed before the 387's were ready to get
motherboards designed.

Can someone send me a simple benchmark that I can use to test it ? If it
will help X11 I'll be VERY happy.

Any replies much appreciated, I can summarize if there is interest.
