XRC CF CARD

I need to find a way to backup a few Yaskawa XRC machines. I have read that I will need a cf card that is 32mb or smaller or a floppy disk. I have also read that the cf card must be formatted on windows 98, an old camera, or possibly with the dx100 pendant. I have about 5 XRC machines that need to be backed up. I also have access to nx100, dx100, and dx200 all of which have been backed up with no problems. I have a 512mb cf card, which was partitioned down to 16mb, FAT. Can I use this card to format in the dx100 controller? If so, what steps are needed? If not, What tools will I need to come up with in order to back up these XRC machines in the most inexpensive route? Thank you for any assistance.
