#47 volume label support for cdroms and redirected drives

[japheth]

Hello,

when I try to read the volume label with function int
21h, ax=714eh, cx=0808h, I get:

• for HDs (MFS): returns without error, but I dont get
  the volume label, it seems to be the name of a file in
  the root dir.

• for CDROMs: returns with error 7100h.

LFN is on, CDROM is mounted with CDROM.SYS and SHSUCDX.COM.

• for HDs (MFS) a volume label is simply not provided by
  Linux; it's a random directory really.

The volume labels for both ah=4e and ax=714e should be the
same (as reported by "dir") and are derived by the linux
root (that's /foo if you use
lredir d: linux\fs/foo).

Reporting a nicer volume label is more a feature request
really, that could be an extra lredir or $_hdimage option,
where you would need to specify it explicitly.

For CDROM via shsucdx (3.0x) you need to load the DOSLFN
TSR: dosemu's LFN support does not cover that.

Thanks for the DOSLFN hint! I just needed the CDROM LFN
label (for a Win32 game [Heretic 2] I'm just testing on
dosemu), I don't really care about HD labels.

Why closing this if you still have to load the doslfn?
Lets make it an RFE instead, as Bart suggested.
