I recently received an older game program as a gift. It says on the box
1.2 Kickstart recommended. I have tried to run this game on my amiga to no
avail. It either gurus or lock-ups or permanently locks up the computer.
It runs just fine on a friend of mine's system. The only difference between
our two systems is that I have 1.3 ROMs instead of 1.2.
I want to use SetCPU to reboot the computer with a 1.2 Kickstart disk. The docs
for SetCPU 1.5 say you can do this, but when I issue
>setcpu kickrom df0: config 0
it just prints
System: 68000
Anybody else had any luck with SetCPU on a plain 2000? Any reason why this
shouldn't work? Dave?

You need an MMU-equipped Amiga for SetCPU to transfer KickRAM; a 68020 or 68030 equipped Amiga 2000/2500/whatever will have one, because it's built into the processor. A plain-vanella 2000 doesn't have one, so KickRAM can't work. Excuse any mistakes in details, I don't have one either... - R'ykandar. -- | R'ykandar Korra'ti, Editor, LOW ORBIT | phoenix@ms.uky.edu | CIS 72406,370 | | Elfinkind, Unite! | phoenix@ukma.bitnet | PLink: Skywise | QLink: Bearclaw |

Any reason why this > shouldn't work? Dave? As mentioned several times before, and in the SetCPU docs as well, loading alternate KickStarts with SetCPU requires an MMU. A plain 68000 system doesn't have an MMU, so it can't load an alternate KickStart with SetCPU. That's simply all there is to it. > -Todd Allendorf > toddal@tybalt.caltech.edu -- Dave Haynie Commodore-Amiga (Systems Engineering) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy Too much of everything is just enough
