True, it should let the user to transparently access the FS via the OS.

Personally, I would, (my preference), and I'd like to be able to call the
next partition 'C' rather than go through my some 2000 program and locate
every reference to drive C and change it to D.

Correction, the BR knows how to locate the files needed to boot that
filesystem, otherwise it's dumber than, well, <flamedeletion>.

Ok, the truth pops out.  I know FAT.  I think I understand HPFS, though
it's been years since I read anything on that, (MAC, right?).  The only
other FS which I know of but don't remember the name was a linked sector
list FS where each 512 byte sector had 500 bytes reserved for data, and
the 12 bytes were used for indexing to the next sector with a bit table
used to indicate unused sectors.  The bootblock for this filesystem
consisted of the first several blocks as being reserved, they did not
conform to the filesystem.  This was so the bootloader just had to copy
x-number of sectors to y-location in memory and transfer control.

I would love to be able to read up on other types of FS's.

Cool, once mounted as such, can you REMOUNT to different specs?

Didn't catch the irony, look at W(%, it's supposed to be idiot proof.

I still wanna run Linux directly from DOS! ;]
