First of all if you put in a 2meg SIMM and the A501 or clone you must have
had only 512K, all chip to begin with. But I'll assume you had at least one
meg, with 512K chip and 512K slow-fast. Note, that's slow fast RAM. It still
has problems like chip RAM because of bus contention. However if you add
fast RAM (real fast RAM) and change your slow fast to chip RAM, then your
drivers go into the real fast ram. Normally FastMemFirst sets the fast and
slow fast RAM to 0 priority, and the chip to -10 (on mine anyway), so
fast and slow fast have the same chance of being used. On mine, at least
130K slow fast is used after booting and maybe 10-20K fast. So my drivers
are also in slow. To get your drivers in fast, I guess you'd need the 1 meg
chip option or somehow set slow fast to -5 pri or something like that.

The above is what I've been able to come up with, it might not be totally
correct, but it explains the problems.
