I've recently read on usenet about some people with matroxes having a problem with autoexec.bat being locked, though AFAIK nobody's actually figured out what the actual problem is.

Is this specific to TCP/IP 4.3? I ask because I've been running a G400 with TCP/IP 4.02t and I've never had this kind of experience whenever I updated the 4.0x stack in times past.

Makes me wish I had access to the newer stack to try it out on this system. I'd be real curious to see what would happen to an original Warp 4 with FP 12 system if I went to any other TCP/IP 4.x stack. Doesn't sound like I'd like it very much, but it would give me an excuse to do a fresh install of OS/2. ;-)
