I'm using a 2.5meg STe.  The only problem is that it thinks it has 
4megs in it.  When I get passed the 2.5meg point, that's when it 
starts crashing and locking up.  There's a program called SIMMFIX 
which reprograms the MMU and TOS to tell it that there's 2.5megs, but
it requires a warm-boot after it loads and is kinda cumbersome.

Depending upon how I arrange the SIMMs, the STe thinks I have 1meg or 
4megs, with varying degrees of reliability.  The best arrangement so 
far is 1meg/256K/1meg/256K (if you started from the back slot).
