I purchased an Acer Celeron 600. I tried installing Win98 on the CD-ROM and it gave me a message saying that the system already has Win98 and it would let me go on to install Win98 from the CD-ROM. It told me to boot Win98 from the hard disk, run setup, and hit F1 for instructions. At the c: prompt I typed in run setup but nothing happened. Can someone please help me. Thank you.
