All versions of Windows 98 support FAT32.
Yes, they do. Windows ME even supports Fat 32!
Windows doesn't provide any tools for converting an NTFS volume to FAT or FAT32. You will have to copy the files on the volume to another location and then format the drive. Note that FAT32 is a much more limited file system than NTFS, and there is probably no advantage to doing so on a server.
Windows Vista does not officially support booting from a FAT32 drive, although it is technically possible. Vista supports FAT32 on Flash drives and hard drives, although it will not format a hard drive over 32 GB as FAT32.

NTFS is the file system that windows XP uses; I know that much. NTFS can handle bigger files than FAT32. FAT32 can handle 2GB files maximum. (So I'm told)
FAT, FAT32, NTFS - and with Windows 8 and Windows Server 2012, Microsoft introduced WinFS.
The maximum disk size is approximately 8 terabytes when you take into account the following variables: The maximum possible number of clusters on a FAT32 volume is 268,435,445, and there is a maximum of 32 KB per cluster, along with the space required for the file allocation table (FAT). You cannot format a volume larger than 32 gigabytes (GB) in size using the FAT32 file system during the Windows XP installation process. Windows XP can mount and support FAT32 volumes larger than 32 GB (subject to the other limits), but you cannot create a FAT32 volume larger than 32 GB by using the Format tool during Setup. If you need to format a volume that is larger than 32 GB, use the NTFS file system to format it. Another option is to start from a Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me) Startup disk and use the Format tool included on the disk.
Windows NT is advance technology than Windows 98. Hence when you boot your computer using Windows NT you will be able to all FAT32 partition. However, If you use Windows NT file system like NTFS than you won't be able to access this from Windows 98. As Windows 98 can only access MS DOS/FAT32 kind of partitions.
Windows 2000 supports FAT16, FAT32, and NTFS partitions.
Windows 98 supports both the FAT16 and FAT32 file systems. The FAT32 file system will support drives up to 2 terabytes in size, while the FAT16 file system will support drives up to 2 gigabytes in size.
