Have a friend with a 9-month-old Dell Inspiron laptop who's had nothing but problems with Win XP. We've deleted the main partition and reinstalled XP, but problem (inability to maintain a modem connection) persists. It may be just a bad modem, and Dell is sending a new one, but he just doesn't like XP, and asked if it's possible to put Win 98 on the computer. I use Win 98, so am not familiar with XP, but know that XP uses NTFS instead of a FAT, and can't find anything that says whether or not it's possible to reformat the drive for a FAT-based Win 98 system. Is it, and if so, how (i.e., can I just boot to the command prompt, type "format c:", and hit enter)?
