Glad to here ya got it working.
Now I know how to use a usb stick also.
When you say you created the autoexe, you mean how I said earlier with the force switch commands based off the floppy autoexe.? If so, I could not get it to work with usb that way. I must of done something wrong. The bios I was downgrading from though was 1002, it might have bigger issues flashing this way than the 1003 version. grats though
