My asus PVI-486 with a POB83 will not recognise any dos or hard drive with an os on it. Tryed usb floppy with dos 6, 7 win98se boot

How are you using a USB floppy drive on the PVI-486 ? It does not have any USB ports and doubt you could get a USB PCI adapter to work with a USB floppy drive on it.... just curious.

I have one of those floppies that use a usb stick cut up into 100 disks. I have found some real 3.5" floppies to try. No usb's on board, but i do have a nec chipped usb card and a usb floppy. i will give them a go. Last i tried, the usb floppy disks were not interchangeable with the real FDD's for some reason.

You are working with a 486 based computer. There are no USB solutions for a 486 floppy drive AFAIK that will work. You must use a real floppy drive.

Or a Gotek as I do 😀

i use a gotek

i'm still having no luck with this. it recognizes a cf card but, like a FDD, will not even attempt to read it on boot, just throw the i/o error. with an off board controller, it too recognizes the cf card and no boot either. where can i get a new bios chip from? i dont have anything to write one.

are you sure your floppy/cf images are good? have you tried them in another computer with success?
do you have normal 486 processor to test?

My other 486 and pentium 1 all boot off them fine. a new bios chip is my next thing.
