You should go into BIOS and check the boot order. If it has a stock CD-R then you will be able to select it as the first boot device. Win XP and some Win 98 CD's are bootable so you will be able to install right off those. Also, if it has a floppy, make a Windows 98 startup disk (those can be downloaded for free) - the startup floppy will let you use CD-R in DOS, it's all rather easy from that point
