Hm, for the case you did not know yet, there is a little on IFS and redirectors in "Undocumented DOS, 2nd edition", and Ralf Brown's interrupt list also contains something on it. However, I have yet to see a precise documentation of DOS-IFS (I will keep my eyes open). In some of the recent issues of the German computer magazine c't there was an article on the OS/2 IFS layer and Windows95 LFNs, but I think, it contained nothing interesting to you after you actually wrote a VFAT TSR. They mentioned some sources of free OS/2 IFS, maybe this could be interesting to you (including ext2fs I think). I could look up the URLs, if you need them. At present, I'm under heavy workload, so I cannot jump into it and help you with COMMAND.COM. Also, I would first like to bring IBMDOS.COM to the update 15/2 level, which would cost me some more weeks (if not months). If you do any changes to IBMDOS sources, could you please put them all in conditional defines, so that we can synchronize them relatively easy with my sources after including the U15/2 patches. BTW, my updated IBMBIO.COM is running stable now (with OpenDOS *and* Novell DOS since U10), and it actually contains *all* the patches of NWDOS 7 U15/2 (huh, there were many...), including a bunch of other fixes, optimizations, and enhancements, although its some KBs smaller now... Since I'm planning to add some more stuff to it (if I find the time), I'm still holding it back for the moment...
