Bozz made some good suggestions (especially about the floppy drive), but if you're using the Win98 boot disk, you can skip the installation of CDRom drivers. You should only have to Fdisk, the drive, then install. One partition is fine for most people, so create the maximum sized primary dos partition, set it active, then power down. Turn the PC on, put the floppy disk in the drive, and boot with CDROM support. When it comes up to the a: prompt, switch to your new drive (c

and type md win98. Then, switch to your CDRom, type cd win98. Then type copy *.* c:\win98. It will then copy all the cab files and the setup.exe to c:\win98. When the copy is finished, you can take out the CD, switch to c:\win98, and install from there. It will install a little faster, and in the future, when you make a change to windows, it won't ever ask for the CD (which is really nice).
Now if you're installing Win2k, you should be able to skip Fdisk completly, put the CD in right after the initial configuration in the BIOS, and tell it to boot from CD. Win2k will format/configure the drive for you.
