Am trying to fix an old PC for a friend, whose hard disk has crashed.
Have installed new hard disk, and loaded DOS. However the CD drive is very old and will only work when connected to a sound card. I have done this and loaded a driver, which recognises the CD drive at boot up. However when I try to access drive D: I get 'Invalid drive specification'
I have set the device driver in Config.sys and set lastdrive to f.
The Bios only has 2 options for device d: Auto and User. I have tried both with no luck.
