single filesystem-health-checking tool
currently SvarDOS comes with two filesystem-checking tools:
CHKDSK (real-mode, Turbo C)
DOSFSCK (ported from GNU via DJGPP, hence protected-mode)
CHKDSK is limited to FAT16, ie. it has no support for FAT32 filesystems, while DOSFSCK is much more powerful but requires a 386+ CPU. This means that pre-386 computers are left with nothing to check their FAT32 partitions.
The need would be to have a single tool that is both 8086-compatible and FAT32-aware at the same time. MSDOS had scandisk that was able to achieve that, so it's certainly possible. It would also be clearer to users to have a single tool instead of two.
