Subject: 387 recognition -- bad coupling ?
Date: Tue, 8 Jun 1993 09:28:32 GMT

Hi Linuxers,

I have a little problem getting Linux recognise my IIT 387 (40Mhz)
coprozessor at boot-up correctly. (My configuration: Am386-40,
IIT 387-40, OPTi-board, AMI-Bios, 8MB RAM, 10MB swap, Linux v99p9).

At boot-up a message complains about a IRQ13-error, and the log
file says there were a bad 386/387-coupling.
But: The coprozessor obviously works, xlander is 20x as fast as
     without coprozessor.
(N.B. The coprozessor is correctly installed, the AMI-BIOS reports
      it correctly and it passes the IIT installation software
      check (under MS-DOS).)

Without coprozessor the system works without any problems, I think
it is a rigorous check in the kernel initialization code --
but is this message serious or just annoying ?

I've already read the posting by Daniel R.Turner.

Sorry for spending bandwith,

P.S: Good work, Linus, Peter, Werner, Lu and all the rest !
     Go on, and don't get disturbed by silly questions (like
     this one)!
