Bootdisk.com

So you just finished rebuilding your home PC with Windows 98 (hey, it was the only free OS you had lying around) and you forgot that you needed to format the hard disk with the FAT32 filesystem first. Or, you needed to make a Windows XP boot disk to help you create a dual-boot system with Vista (yuck!) or Linux (_yawn_). What do you do?

Luckily, Bootdisk.com can help. Go to their website, download the appropriate file, and image your floppy disk (assuming that you didn't throw them all out back in 2002). It's worked for me several times.
