Hi!

I have an A2000, Rev 6.2 motherboard (thus Fatter Agnus and 1MB MEMF_CHIP),
and a Supra2000 RAM board with 2meg in it.

My question:
Do I have to run FastMemFirst in startup-sequence?
If I remember correctly, the $C00000 memory was originally slow-fast RAM since
the original Agnus could only address the 1st 512K of the standard 1 meg.
The Fatter Agnu can address it all, giving 1 meg MEMF_CHIP.  However,
does the system still default to using $C00000 first, or does it know
enough to go to the true fast RAM?
