Fastfat32 is a file system driver that enables reading and writing FAT32 partitions on NT 3.51 and NT 4. To use, copy fastfat.sys and fs_rec.sys in %systemroot%\system32\drivers and reboot. If you use the Windows 2000 boot loader, it is even possible to boot NT 4 from a pure fat32 drive. From: http://ashedel.chat.ru/fat32/
