I have a 386 PC104 with MSDOS 6.22 installed. It booted from unit C (disk on Chip) without a problem. Today, after a couple of successful boots, it stopped booting and it got stuck right after showing the system configuration and right before starting msdos (see picture). Worth mentioning that the floppy drive led stays on.

I could still boot from a floppy disk without problem. I was able to access unit C, and everything was there. I formatted unit C and transferred the system, but the problem persists.

What can I do to fix this??

Picture 1: shows where it gets stuck when booting from C

Picture 2: shows the board booting from a floppy

I hadn't thought of that. Thanks! That fixed it.

I still don't understand what happened. It was working fine, and all I did was copying a game from a floppy disk to the C drive with "copy a:*.*", and next time I tried to boot, it didn't.

I think I've been spoiled by dosbox... Is there any MSDOS antivirus I can download that would be effective with most viruses?

try my portable DOS antivirus, perhaps some of your floppy disks are infected as well if it was indeed a virus
