Re: HELP: DOS - mouse problems under Windows 2000 on an IBM Laptop

Thank you for your help, Arkady.

As I recall CTMOUSE said nothing when it installed, other than those
messages about not getting access to COM1 and COM4.

Yes, I believe those error messages were from Windows.  They appeared in a
typical windows box, with an OK button, and said the program would be
terminated because it could not read the COM ports.

And thanks for the suggestion about partitioning.

     Windows 9x/Me presents for DOS programs access access to mouse through
own drivers. I don't know if NT/2k/XP does same (although in theory they
should).

     There nothing guaranteed when running DOS mouse driver in Windows (9x
or NT) DOS box.

     This message from Windows?

     Not enough information.

     If I right understand, both TrackPoint and external mouse are PS/2
devices? And CTMOUSE says something like "Installed at COM1 (03F8h/IRQ4) in
Mouse Systems mode"?

     This mean that CTMOUSE not detects PS/2 mouse (as expected - Windows
not givess access to devices which it controls itself) nor erial mouse and
installs handlers at COM1 for Mouse Systems mode. All of this explained in
CTMOUSE.TXT. Unfortunately, we can't help you in this case, you should
install some other _Windows_ mouse drivers from IBM and/or external mouse
manufacturer.

     It should (through CTMOUSE or other DOS mouse driver).

     You should try Partition Magic from PowerQuest or Partition Commander
from V communications - they allow nondestructive partitions management
(resizing, moving, creating). After this you may use W2k bult-in boot
manager to select which partition load at startup (see BOOT.INI file
description).

     There is another trouble and /V not helps for this.

     Who says "it not supported"? If it will be finded, then it will be
supported. But it not finded (because W2k prevents this).
