win 98 loads extremely slow

I’ve formatted my C:\ drive and tried to load win 98 from a cdrom.It runs so ultra slow that the estimated time in the lower left corner says 224 minutes. I booted from a floppy and still just as slow. I have loaded win98 on this machine dozens of time and never had this problem. IT’s an amd 500mhz 13.6 hdd, 96 megs of rm, nyone out there have a clue? thanks
