...Dell 486/33 that has been upgraded to a 486/66. The cd rome has been taken out and I just keep getting the message Device driver not found, No valid cd rom device selected. (1) How do I bypass this? and is a cd rom actually needed to run ms dos on this computer ? (2) and can I install windows 98 on this computer? I have a windows setup hard disc and a windows startup hard disc. (3) Do I need to install a cd rom and get a cd with windows on it to do this? ...
Dell 486/66 probably has DOS 6.22 and Win3.1.
(1) Ignore it. CDROM not required for DOS.
(2) Win98 requires the following:

You said you "...have a windows setup hard disc and a windows startup hard disc. .." You mean CD, not disc?
(3) Install of Win98 requires CDROM, unless you have Win98 on floppy disks.
