From what I understand, Win95,98,ME reads memory from the top down (unlike
Win2k which reads from the bottom up).  This would mean that if you are only
caching the first 64MB of RAM, the initial memory that Win95, etc. reads
would not be the same memory that's being cached.  This means that you would
have a performance hit.

Also, if memory serves, there was a way on some VX boards to increase the L3
cache to support more memory caching.  Getting ahold of the cache RAM to do
this might be a bit of a trick at this stage of the game, though.  Good
luck!
