[comp.os.os2] Problems With Mouse after Booting OS/2 from DOS

ajai@sce.carleton.ca (Ajai Sehgal) (01/16/90)

I'm running OS/2 V1.2 (dual boot) with DOS v4.01 on a 10MHz 80286 based system
(ATI VGA Wonder, 80287 , 40Meg Hard Drive, COMM 1 = Logitech HiRez Serial Mouse,COMM 2 = 2400 Baud external Modem COMM 3 = 1200 Baud Internal Modem, 4Mb 80ns 
DRAM).
When I boot 0S/2 from DOS using Boot.com my mouse will not respond (at all othertimes it works fine). The only way to fix the problem is a COMPLETE POWER DOWN
AND POWER UP (Ctrl-Alt-Del and Reset [H/W reset] don't work). Has anyone else
experienced this problem? Any suggested solutions? There are no IRQ or Port 
Address conflicts. My "clone" is based on a Suntac Baby AT motherboard and has
never given me problems before (and doesn't under other circumstances).

Try to disconnect Your mouse for a few seconds after booting OS/2.
I had this problem with version 1.1 and the Logitech C7 mouse.
It seems that the Logitech mouse gets some wrong data bytes which
cause the hang-up.
