         (I have finally done it!  I got a 2 meg ramdisk to work on
         my DOS only 6300+!  The hotline bulletins were no help.  
         Previous postings did not work, I was going crazy!)

         For those of you out there who have DOS ONLY 6300+'s and you 
         want to install a 2 meg ramdisk (great for C compiler) this 
         is what you do:
         
               You need:

                     PC 6300+ with 1 meg on motherboard - you only 
                           need 640K, the other 384K gets wasted.
                     MS DOS 3.1.
                     AT&T Enhanced Memory Expansion Board populated
                           with 2048 MB memory.
                     AT&T AEMM, AEX and ramdisk software (comes with 
                           board).

               On the memory board set:
                     SW1: 00000001
                     SW2: 11100000
                     make sure jumper is set to 6300+ setting 
                     (default).

               In your config.sys file put at the top:

                     DEVICE=<path>aemm.sys
                     DEVICE=<path>aex.sys 2048
                     DEVICE=<path>ramdisk.dev /m/extm /DL

                     where <path> is where ever you happen to hide 
                     these files.  The ramdisk.dev is the one supplied 
                     with the memory board, NOT the one with DOS 3.1.

         The /m/extm tells the ramdisk to take all extended memory and 
         use it.  The /DL is the CRUCIAL part that tells the ramdisk 
         the leave the lower 1MB (640K for system, 384K wasted) alone! 

         This will produce on your system a 2MB ramdisk known as D:.

         It really works.
