Have you ever installed windows 98 on your system, and wonder why it runs so slow? Then finally you install a program that shows you the CPU usage, and it hangs around 45-60%? I found that most of the time, its hard drive related. Believe it or not, if you have a drive over 60 gigs, it will cause you to have high CPU usage. I discovered this recently when seting up my p4 2.4 after buying my AMD 64. Because i had problems with win98 and high cpu usage. I installed it on a 6 gig drive, and didn't have as high cpu usage. So if you have a driver greater than 60 gigs, i'd recommend seting up a partition to 60 gigs for win98.
