One easy way is to find a friend with an old Windows 98se or earlier
computer, and have him format the card.
If your going to do anything much with this machine, you almost have to have
the floppy drive. While it's possible to get by without it, there's much
heartache and frustration involved.
If there's no friend, you need to Google around for a boot disk creator.
How big is the card? If it's over 2 gigs, you may have trouble.
