PC Chips M598

Post by Mike »

I have a PC Chips M598 V.5 motherboard. My Tyan S1598 board crashed due to a bad power supply, but my K6 2-500 chip survived. The M598 board will run my K6-2-500, but I can't find the right pin conf. to attach my PS2 port. Can't get my mouse to work. Anyone know how to hoolk up a ps2 port?

This is the pinout of the PS/2 connector itself - http://www.burtonsys.com/PS2_keyboard_a ... nouts.html

Although I have not looked at that particular PC Chips manual, it has been my experience, that in their eagerness to sell their proprietary minicards, (mouseport is part of one of them), their manuals provide no information whatsoever about the function of the pins on the mobo. The mouse end of such ports is standardized, but the mobo end is not; and if you are using a normal PS2 mouseport as opposed to one of their proprietary minicards, you have to alter the wiring pattern of the mobo end of the port to match the configuration of the mobo. But their manual doesn't tell you what the funtion of the pins is; = problem.

Only time I ever built one of their boards, I was lucky enough to score one of their proprietary cards to go w/ it. If it were me trying to guess what the pinout is, what I would do is download a selection of manuals from other manufacturers whose manuals are more informative, since I have only seen 3 different wiring patterns used re mouseports. ASUS used a 2x4 double line of pins, and everybody else used a 1x5 or 1x6 single line of pins w/ either one or the other of two different pin function configurations.

It is a 2 X 4 row of pins with one missing. The Manual is of no help. I will look at Asus boards and see if I can find anything. I have hooked up several PS2 ports in the past but you must know the motherboard layout.

Thanks.

In that case there is an excellent chance the mobo mouseport pinout is the same as an ASUS P5A-B which also has one pin missing on a 2x4 pin layout. Try downloading the manual for a P5A-B, cause I think ASUS manufactured the "proprietary minicards" used by PC Chips. (I have some of them).

AFAIK the only difference in PS/2 mouse wiring is the configuration of the pins, 4/5/6 doesn't matter as only 4 are utilized...

1) Data
2) GND
3) 5v +
4) CLK


The last mobo I had to wire a PS/2 adapter to (without a wiring diagram) required me to dismantle the mouse to establish the 5 volt and ground wires, after that... a little guess work was all that was required ;)

For your reference, the P/S2 pinout of the PC Chips M571 looks identical... and a wiring diagram and specifications can be found here @ Frank Zabkar's M571 Data page

You are right Taz. But on his board, (Like an ASUS P5A-B), there are 7 pins on the mobo that the mouseport plugs onto. Question is which 4 are used; and what are those 4 used for? The link you supplied may provide the answer to that question.

It Lives

Post by Mike »

I was able to get the mouse to work. I used the 4X2 pins for the PS/2 Mouse. If pin 6 is missing, I used 1 Ground, 2 Data, 3 -- , 4 +5, 5 clock, 6 Missing, 7 --, 8--.

I think something is wrong with the 18 pin ATX form card connector, should be able to hook up USB and PS/2 there also, no luck. Looks like the same 18 pin connector as ASUS.

Thanks for the help. Trying go get this board up and running for a upgrade for my mother.

I had similar problems getting the USB ports working on a P5A-B. Checking the manual showed that whereas most USB ports come w/ one port wired opposite to the other, the P5A-B required that they be wired the same as each other. Could be your board works the same way.

The missing pin is like a keyway (for the original fitment P/S2 header) naturally 3 of those 7 pins are redundant ;)

I don't follow what you mean about 'this' 18 ATX pin form card connector? AFAIK there should only be one place able to sustain a P/S2 connector for the mouse on any given motherboard ;)

ATX Form Card

Post by Mike »

The ATX Form Card Connector is a 18 pin connector on the motherboard that has 2 USB ports, pin 1-4 and 10-13. PS/2 mouse 5-6 and 15-16, and Infra Red pin 7-9 and pin 17-18.

Yes this board had both a 4X2 pin for the PS/2 mouse and the 18 pin connector.

Also for ref, the Gigabyte GA-586-TX-2 PS/2 mouse connector is pin 1 Vcc, 2 Grd, 3 Data, 4 clock.

Later Mike....

Thanks Mike, I'd never encountered such a connector bracket before, as for the GA-586TX2 (I also had one) luckily mine came with a P/S2 PCI card extension... so I never had to reverse engineer the header ;)


Hmmmm... I may inquire if the person who recieved the '586TX2 would like an upgrade, I could reclaim it then :D

Gigabyte GA-586-TX-2

Post by Mike »

Back to the Gigabyte GA-586-TX-2. The CPU speed is set with jumpers, if I update the bios how can I set the speed for the K6-2 400/500 chips. I have a good board and would like to see if I can upgrade it.

Thanks Mike...

Thanks.
The Manual link provided does list the ATX form card connector pinouts on page 19 ...not page 15 as listed in the "contents" . Whether they are proper or not is another thing.

From my assessment of the pinouts as posted from the link the middlegroup of pinouts are for the mouse , the low numbered ones are for the USB ports and the highest ones on the other side of the mouse are for the IR port.

Since the mouse (PS/2) port is the one needed I would make sure the wiring is going to use Ground #5 as long as you can confirm the wiring of the PS2 connector is understood to which colored wires represent GND / V5+ / Data /CLK .

There is a way to check the wiring using a small LED light ,typical good M.B. 3v battery and insertable wires to form a connected "light" circuit.

Mike are you trying to use a spare PS/2 port connector from another system on the PC Chips m.b. ? ...wiring will not match most likely and then you will have to manually rewire your PS/2 connector for the Motherboard's pinouts.

Your pinouts for the mouse you listed here are 5-6 & 15-16 ...I think that is wrong as the pintouts will be closer in numbers (usually) ...so 5-6- 7/8/9 type of thing .
Tazweigon's provided link of the manual (pg 19) should be relooked at again.
