I have a friend who fried his computer pwr supply when his power line neutral broke. It was an old Dell (about 1996 mod). I removed his drives and reinstalled them in an even older tower with a mother board and CPU already mounted. This tower did not have the standard PS/2 connectors for the keyboard and mouse. The mouse is connected to a serial input port with an adapter (9 pin serial port to PS/2). I manage to boot up Windows 95 but I get the message “This computer does not detect the presence of a mouse. Shut down windows to connect a mouse to the PS/2 connector”. And, sure enough, I do not get any response from the mouse. The BIOS is setup with “AWARD SOFTWARE INC” (Now PHEONIX). The CPU is an Intel 1 (or 486), I have searched through the BIOS setup and chipset setup trying to find a problem with no results. Any suggestions?? My friend has little money and I am trying to keep cost down. I feel the problem is probably very simple but beyond my scope. Thanks for reading this, Jim
