Hello , glad to make my first post in this great forum.
So i m having an issue with a newly acquired 486 DFI pc.It has a 16bit isa multi controller that i can't find the jumper settings for it.Its DFI MIO 500 rev D. The mio500 jumper settings i ve found on the net dont correspond to my card (mio 500 rev d. is different than mio500).Motherboard is DIAMOND FLOWER, INC. 486SX-16/20/25UCE 486.
My problem is that i cant make floppy to run my dos boot disk.System hangs after post bios info screen.I have a 1.44mb floppy set as A drive and 360k set as B.The ribbon cable and drive are tested on another pc and they both work fine.I tried loading bios defaults (AMI bios) and nothing happens , only difference is if i set A drive as 720k i get a message invalid boot diskette , or else if i set it to 1.44mb system hangs after post info screen.
Please any help would be appreciated.
