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? -- Rich Carreiro - Most Biased Boston Celtics Fan! Get well soon, Johnny Most!

No, you don't. $C00000 memory does not exist in your system; the onboard memory is address-mapped to chip-accessible range. -- ======================================================================== Joe O'Hara || Comments represent my own opinions, Commodore Electronics Ltd || not my employers.
