I have put a new 6.4 gig harddrive in my old 486DX266. My problem is I wanted to put 98 on it but it is on a CD and I can not get a F: drive letter recognized. I know it needs to be in Autoexec.bat but I do not seem to be able to use the EDIT command in DOS. I finally was able to find some of my old 3.1 disks and now have 3.1 installed but no way to access my CDROM. I do have a few DOS 6.2 disks but I am not sure I have all of them. How many should there be. Can I put on my Windows 98 upgrade edition on without first putting on 95? Hope you understand my problem. Can you slowly walk me through getting the CDROM letter recognized and available for use?Thanks, John.
