Get a boot diskette from http://www.bootdisk.com and notice what it uses for the CDROM driver and what it used in config.sys and autoexec.bat to get disk letter.

After booting to C: command line prompt the CD-Rom is unavailabe for reloading Windows 98SE. Theres only one harddrive with one partition. Have typed in D: E: F: and stays at the C: prompt.
