I have tried 2 brackets from motherboard to serial port and tried switching the plugs around but nothing

There are different pinouts for serial port headers. The two brackets you tried might not have the right one for your board . Unfortunately, the manual does not seem to provide info about what your board uses .

The manual for version 4 of the board does list serial port pinouts (page 18 of the manual or page 23 of the pdf). Hopefully they are the same as for your board (even if the board layout is different) :

Here is the pinout of a DB9 serial connector for reference :

Had the same thought. I ran into this problem once too. Trying some spare brackets did the job because 1 turned out to be a compatible one.

I'm positive that the bracket I'm using is compatible with the pc. So it's either the mouse driver or for some reason the port is just not working (mobo issue?)

Does DOS need drivers for the serial ports?

No

I give up, I think it is a faulty motherboard

How are you certain that the bracket is compatible? Did it work before in the board?

You haven't explicitly stated that you confirmed the BIOS shows the com port to be enabled, and what IRQ and I/O range it is using.

There's also a binary, comtest.com, included with CuteMouse. See if that tells you anything informative about your Com ports.

Forego the /m switch and try /s, as well.

how many type of brackets are there? I have 3, 1 which does not fit due to a hole being blocked. Two others which work perfectly in my other socket 7 system.

In bios both com1 and com2 are set to auto. I can manual set them but for as far i have seen it makes no difference.

Just ran the comtest:

COM# ADDR IRQ# TYPE ATTACCHED
-------------------------------------------
1 03F8 4 16559A (with FIFO)
2 02F8 3 16550A (with FIFO)
3 0000 not found
4 0000 not found

just removed one of the brackets and nothing changes on the report. So it is just reporting back from the MOBO.

Try hooking to Com1, then ctmouse /s1, if that fails then go to Com2, ctmouse /s2 . The automatic settings on the BIOS should use those defaults, but if you go to manual configuration you can be certain it matches up.

I have run both and even swapped the connector around, tried a different one..

but all the time:

Error: device not found.

I spend too much time already 🙁

There are at least two different ones :

Thanks for thinking with me. I have both versions of the serial bracket and one doesn't even fit so I'm quite sure I'm using the correct one. I'm really starting to believe the controller is broken.

Almost all my IO cards and 486 motherboards use a connector where the pin ordering is :
12345
6789
While one of my IO cards and all my Pentium and newer things use :
13579
2468
You can tell by unscrewing the connector from the bracket and pulling the black cover back a little, if you see writes that don't zigzag it is the first, if zigzagging then second ordering.

Yesterday I started working on the K6 machine again (installed a voodoo1) and was annoyed by still not having a working mouse. I started googling again and ended up on my own thread (this one). I started reading again and opened the manual @Darry shared for version 4 of my motherboard. Here I could see that one of the pins on the serial heading on the motherboard does nothing. Then I thought about the serial bracket I have lying around where one of the holes is blocked, exactly where the pin of the motherboard says it does nothing. I drilled out the port on the serial bracket connector. Connected it to the motherboard, connected a mouse, and VICTORY. It finally detected a mouse.

My girlfriend wishes I would say it more often. But you guys were right all along that I was using the wrong connector/pin layout.

Thanks! 😀
