[comp.sys.ibm.pc] MSC PC Mouse Bus Plus + Windows/386 + Toshiba 5200 Problem

spence@utpsych.toronto.edu (Ian Spence) (04/02/89)

When I install Windows/386 on my Toshiba 5200 (4Mb RAM) with NO pointing
device specified, everything works perfectly.

When I specify MSC MSMOUSE Bus Plus (using IRQ 10, Port 338) and make the
appropriate drivers available to Windows Setup, everything apparently goes
smoothly.  Windows/386 runs normally, and the mouse functions as it should.
But, the only applications that can run are Windows Applications (such as
CLOCK, NOTEPAD, ETC).  If I try to run ANYTHING else there is an immediate
crash back to MSDOS 3.3 with the error message "FatalError 0x0404".  This
error is not listed in the Windows documentation.

BTW, the mouse works perfectly with all kinds of other software, e.g.
Ventura 1.1, QuickC.

I've tried every possible combination of things I can think of (including
trying to use IRQ 15 with Port 238; funnily the MSC TEST program reports
IRQ 12 even though the jumper is on 15).

Anyone have any ideas?  Anyone at MSC Technologies listening?  Or Microsoft?
