Hi all.
I am currently in the process of restoring a Unisys 486 machine, and everything is working beautifully so far. Except for one tiny issue that I have with the floppy drive. In the BIOS it is set up as a 1.44mb floppy. And it will boot such disk's as if nothing is wrong.
Though if I try to format a floppy or read some floppy disks, the computer begins to think that this is a 360kb drive, and makes a media error, sector error and all sort of other failures.
I have tried two different floppy drives, and 4 different floppy cables. And I am beginning to think that the onboard floppy controller is defect. Do you gyus have any suggestions to what I can try and look for? My thoughts are that the controller is dead. And I am thinking about disabling the onboard IDE/Floppy controller and use a generic controller. There is no hurry here, as I have packed the machine away in the closet, in order to do another 486 project, that are well overdue. So yeah.... I might start looking at this within the next week and a half.
Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick....
