I replaced my 2 gig hard drive with a 40g. then put my 2g into another pc without erasing anything. When I try to boot up it goes to the Windows 98 screen and freezes forever. If I boot with the W98 boot floppy in and reply to use CDROM it gives me the subject message and says the required device or resource is not found for VFAT. What's that mean and why can't I get the system up?
