Serial mouse detection

Hi everyone, I am trying to restore a old PC, Pentium 133 and have some problems with the mouse.

The mobo. Chaintech 5IEM, has onboard serial pin (10pins) and required a serial connector, may not be correct term and it is something that you need to fix to the slot and there is a cable to connect to the onboard 10-pin serial port.

The mouse is a serial mouse and it is confirmed to be in working condition because another system have no problem with it.

I tried to play with the BIOS setup, from disabling the serial port to assigning com1 thru com4 and win98 is still not been able to detect the mouse.

I disable the serial port thru BIOS and delete the driver from win98, then enable the serial port again and win98 is able to detect the serial port, does this show that the serial port is in working condition?

I have tried disabling the onboard com port and add in an ISA serial port and win98 still can't detect the mouse.

I have tried another mouse and still the same result.

Any other methods that I can troubleshoot the error? It is not the mouse, so it is either the mobo or win98.

Please help. Thanks.
 
try using another mouse , use DOS and try(Ofcourse u should have dos driver, if u don't have it search for it) if it is detected or not.
 
Good Lord.... Let's see if I remember this.

You need to assign COM1 and 3 to IRQ3 and COM2 and 4 to IRQ4 if i'm not mistaken, just make sure your irq's are also enabled. For a serial mouse you absolutely need an IRQ.
 
Also, the serial mouse is not going to be plug-and-pray so Windows 98 is not going to just "detect" it, you will have to run through the "Add New Hardware" wizard in control panel.
 
Hi,

I have tried using the same mouse in another system w/o problem and the p133 can't detect the working mouse from another system. So I guess the problem lies with the p133.

I have tried to using DOS mouse driver and mouse still failed to work in win98.
I have also tried adding the mouse via "Add New Hardware" and did not work as well. 🙁

NicColt > How do I assign the IRQ for the COM1? I can't find it in BIOS setup or Win98->device manager.

The problem may be due to IRQ as even add-on card (serial port) does not allow the mouse to be detected.

Thanks.
