So I wanted to build a new 386 system with a KMC A419-8 (ACER ALi M1419) motherboard. All went well except for the fact that I do not get serial mice to work on the system. CT Mouse driver recognizes the mouse, but it doesn't work either in Windows (3.1.) or any DOS games.
Here is my unsuccessful troubleshooting so far:
Tried different serial mice (Logitech and Microsoft) - all got recognized by the drivers
Tried Logitech and Microsoft mouse drivers instead of CTMouse - recognized the respective mice
Tried different addresses on the COM ports
Tried different COM ISA cards
Replaced the PSU as I thought there might be a problem with the -12V rail
Is there a known issue with this board? Any other causes that escape me? Would be great to get the mouse working on the system.
