Hi folks. I am happy I have found this great forum. I have recently got nice 486DX4/100 machine locally (exactly 28 years ago I got the same machine as my first PC, when I was young guy). However I have problem to get serial mouse working on it.... Driver is installed, but mouse does not respond. I have tried used Genius mouse with gmouse.com, then brand new out of the box microsoft ps/2 mouse with ps/2 to com adapter and installed own drivers, and brand new, gm-6 genius mouse (i am stupid I have tamper opened 1987 NOS sealed package just for the test....). Of course none of them working... Inspected internals I have found, that COM1 cable was connected to "gameport" header on the mainboard - well I was happy I have found the problem, and connected it correctly to COM A, but no difference.... I have read through few topics here from people who had the same problem, but noone posted if it was resolved and how.... I know it seems to be most likely a pinout problem from mainboard to COM port.... The question is very simple and clear - please does anybody have correct pinout diagram? Or link for a cable I need to buy to get this thing working? Or maybe some I/O card with which I can get this solved? Please for advice from those who had sorted this out....
btw I see that board has also header marked as "mouse" at the very left bottom, believe to be PS/2 mouse connection, however I do not see any option in BIOS related to this... Bios version says v4.51PG, 1.72F (10072A4IBZ1A), and has modified logo "funworld". Please advise.
