I have an AST 486 4/50 computer. While trying to set the cdrom drive something happened and now I can not boot from a floppy disk. There is no OS on the hard drive. Normally I should be able to boot from the floppy drive using a system disk. However when I turn the system on, I get the error message 'invalid system disk. Replace disk and press any key to continue'
even when I use a verified system disk.
Can't do anything without first booting the system from floppy. Please give some idea. If anyone has the specific AST Bravo 486 4/50 computer, I would appreciate if you could send me your bios settings.
