Can you get a directory display from the CD when you try:
dir e:
If not, you may have a dirty CDROM drive, try a cleaning disk.
Check the other drives as well. The D: is a RAM drive (2 meg) set up by Win98SE boot floppy for utilities and will show several DOS utilities. C: is your hard drive partition, I don't know whether you have put any files on it yet or not. A: is your floppy and B: is a placeholder for a second floppy or cartridge drive.
If you get normal directory displays from these but errors from the CDROM, you may have a defective or dirty CDROM drive or CD. Cleaning it will fix that.
Try putting a different CD in the drive and see if the directory shows up at
dir e:
in DOS.
