Installing Com3 & Com4

I have a P166 MMX (Award 4.51PG BIOS) with 32 MB RAM
system running under Win95. I have a 14.4 K internal
modem. My current Serial settings in the BIOS are,
Serial port1=3F8/IRQ4 and serial port2 = Disabled.
Both the mouse and the modem are working fine.
Now I wish to add one more serial port to the system
for which I have attached a Magic IO card. This card
has two comm ports and works fine on my friends PC under
win'95. However, on my system, the moment windows starts,
it gives an error that "Windows didnot detect a mouse
attached to the PC. You can safely attach a serial mouse now".
Pressing Return takes me to windows but without
mouse support.
How do I solve the problem ? I have tried changing
Serial port settings in BIOS to Auto etc.,
but with no success.

Go into the Device Manager and check of conflicts.(Yellow exclamation mark). If there are 2 under mouse then delete one and restart your system.
If that does not fix it, check your mouse and keyboard connections. If it is and ATX it's easy to get them confused.
Depending upon which com port your mouse is using you may want to disable com 1 and enable com 2.

Dear asnack

I have checked the device driver. There are no
yellow escallation marks. There are no two
mouse drivers also. My current setup (without
com3 & com4 card) shows mouse connected
to com1 & modem connected to com2. Both
mouse and modem are functioning OK.

However, the moment I put I/O card with
additional ports (com3 & com4), I get the
message that windows didnt detect the mouse
and my mouse stops working.

I am unable to do further checking as the mouse
is not there.

Dear Confused3141,

Thanks for your suggestion. I have carried out the
procedure provided by you and am able to connect
the IO card to the system and mouse now works.

However, I am finding that IRQ of com1 & com3 (=03) is showing a conflict. Similarly, com2 & com4
are using the same IRQ(=04). I have tried to change
the IRQ but have found only 03 & 04 available.

Though the mouse is working, in devices I am seeing
a yellow mark near it. The Properties option shows that the mouse is not working properly or is not connected & hardware code 24 is displayed.

I do not how to solve this problem. Pl. guide.
