Yes, I remember this. It was called UMSDOS. It was a filesystem module
that could be configured into the kernel that would allow you to use a
part of your DOS disk for your linux filesystem. Extra filesystem data
was kept in an especially oddly named DOS file. Many of the very early
distros: sls, slackware, yggdrasil, etc. would include this option.
UMSDOS was removed from the kernel tree some time back because it wasn't
being maintained.
