Enable48BitLBA (see link in my sig below) Just 1 more question (sooner this gets answered the sooner I can go to work and give it a shot) How do I install that? I realise I have to do it in DOS mode so I would assume instakk 98 first and do something in real DOS mode? Assume that would mean copying and pasting that using command prompt? To what folder? Just search for "ESDI_506.PDR" and you'll find where the existing file is, copy the new one over it from DOS mode (actually, it seems you can copy it from within Windows as the file is not locked unlike the kernel, but a reboot is probably needed to load the new driver.)
