Good.

: I ripped out support for DOS != 5.0 and FAT != 16-bit.

Not good.

: I removed everything related to the LFN cache (cleverly tucked away in
: the PSP).

? (Sounds good but I'm not sure.)

: I replaced the CRC algorithm for LFN->SFN mapping with simple LFN

Good.

: I threw out support for Unicode.

Hmm...

: Rather than devour unused directory entries as M$ does, I write the LFN

Not good. While I agree their choice of implementation isn't good,
that's what we have today. It isn't good that if you reboot to WINDOZE
all your LFNs are gone! (Yes, your version isn't worse than Bill's.)

: This was ages ago; I haven't worked with the driver for some time.
: The idea was to burn away everything but the bare essentials and get the
: basic LFN TSR engine stable.  Anything I chopped can be restored later.

Ok. What I want to have is a MS-compatible version. 

Point me to where I can download your version.


Right,
