I do believe I remember reading something about this myself, but it
was in a manual for a different card - I think it might have been a
generic S3 card with 1MB DRAM.  One of the things I do for a living is
build clone computers and as a cost effective solution we offer a
generic S3 card, low price but still having the quick DOS/Windows
response of the S3 chip.  I think this problem has been fixed in newer
versions of this card.

Before going out and buying a new video card, you might want to
consider reconfiguring your modem to use a different COM port.

- Your mouse is more-than-likely using COM1.
- You probably have an existing COM2 port in your computer, though
  chances are its not being used.
- COM3 is not a good choice because it can conflict with the mouse.
  COM1 and COM3 both use IRQ 3.

My suggestion is to disable the existing COM2 port (if it exists) and
configure the modem for COM2.  There are two different ways to do this
depending on your computer.

1) Almost all newer computers, and most name brand computers both old
and new, have there COM ports, video, IDE, etc., built directly on the
motherboard.  Disabling the COM port can be simply changing a jumper
on the motherboard.  If this isn't the case, then there should be a
way to disable it through the computer's CMOS.

2) If your computer has an IDE/serial or serial card that has the COM2
port on it, then you can disable it by jumper setting on the card.

Hope this helps,
