[comp.unix.xenix.sco] SCO UNIX V/386 3.2 with Intel 387 cooprocessor: What's wrong with it?

dimitri@cui.unige.ch (Dimitri Konstantas) (02/21/91)

I have an AST 386/25 and I tried to install the 387 cooprocessor,
but it seems that the SCO UNIX does not like it!
It panics at random moments (probably because of some signal) and it cannot
boot.
Has anybody installed the 387 cooprocessor with SCO UNIX V?
Does is works? Were there any problems?

Any reply (possitive or negative :-) will be highly appreciated,
since it will allow me to track the problem (maybe the 387 that I have is
broken!)

thanks for the help :-)

Tons of people have '387s in their machines running sco *nix.  kithrup
recently got a '387 clone, and is doing fine.

A coworker recently had a similar problem, and my response was:  does the
machine boot DOS?  Does the machine recognize the fpu during boot time
(*before* unix boots, that is)?  It's possible some of the motherboard
jumpers and switches are not configured properly, which could cause
problems.

	Here at PEM all maschines are running with SCO UNIX 3.2.2 and there
	no problem with the CO.
	But during the installation we alweays make the same mistakte. We
	forgett to enable the CO on the motherboard, so the kernal will
	panic.
	After setting a new jumper configuration on the motherboard everything 
	is well.
	So have a look on your motherboard, wether there is a single jumper
	for the CO. Try the other constelation .

	Hope this helps
