However, have you tried to use 4 standard primary partitions in DOS? In my experience, it doesn't work YMMV. An issue with those limitations is that (I think it is a BIOS variablility problem) some systems using Windos can "see" only the first primary partition in a Primary-Primary-(Extended/Logical)-Primary situation and that it is more sensible to use Primary-(Extended/Logical)-Primary or just Primary-(Extended/Logical). Another issue I have found is that NTFS is easier for WinNT and FBSD to share than any other format. Go figure. -- Regards, Brian
