I don't think FreeBSD, or any other BSD, ever had HPFS support, and I just 
looked again for FreeBSD, not even read-only.

If I had anything on HPFS, I suppose I'd use Linux to copy anything I wanted to 
save.

OS/2 was just getting an experimental third-party driver for FAT32 back in 
2001; I never got to use it.

FAT32 is now good as a lingua franca file system for exchanging data between 
various OSes but is very limited on ability to use large partitions: not nearly 
as good as NTFS or Linux or BSD file systems.  Now EXFAT has been developed to 
remedy FAT32's inadequacy for large partitions.

Not having a file system better than FAT32 is a big limiting factor for FreeDOS 
and ReactOS, at least for doing big things, perhaps even rebuilding the OS from 
source.
