A simple question regarding 3COM's 3C501 etherne board. I've been using this board in an XT286 (essentially a 6Mhz AT - "real IBM") for more than a year now without any problems. I just started looking into an X server for this system and have found one, now the fun starts... I figured I would add some LIM 4.0 RAM to my AT (since X would use it) - I went out and purchased a BocaRAM AT Plus w/2 Meg of RAM. When I boot the system with 2 Meg allocated to LIM 4.0 expanded and the 3C501 (LIM 4.0 starts at 0d000) the EMS driver does NOT see the RAM board - if I take the 3C501 out of the system then all is fine. It appears that the 3C501 is allocating that address space (which is in the middle of the LIM 4 spec - you cannot use LIM 4.0 without this address). I've called 3COM to no avail - Boca said "yes - lots of network adapters use that space, just set your ethernet adapter to a different address", well I can't - and nowhere in the 3C501 book does it mention address 0d000 - or anything about any memory addresses being used by the board (except for the optional PROM which I don't have - so it's disabled and the jumpers are set for EC00 anyways). Has anyone else run into a similar problem - does anyone know of any ethernet boards that allow you to "move" the address around? -Thanks in advance (I hope) chris -- chris@bingvaxu.cc.binghamton.edu Chris Peck chris@bingvaxa.bitnet SUNY Binghamton, NY --"Any opinions expressed above are mine, ALL MINE!"--
