I have a friend who recently bought a 68020 board I had been using for a few years. On my system it worked, but on HIS, he gets a "Memory Configuration Error" when he does a reboot holding the two mouse buttons. Oh - Forgot to mention. It's the COMMODORE 68020 board, so a reboot while holding the mouse buttons brings up the 68000 or 68020 menu. When he gets the error here, it still seems to work, but not as well as it should. When he operates in 68000 mode, programs which USED to work no longer do 100%. A few games screw up etc. He blames me. I don't have an answer. Do you? -- Jeff Goebel. Comspec Staff.

What I suspect is happening is the same thing I get with my A2620 and that is an "Out of Configuration Memory" which is caused by the ROMS on the card not being the latest version. I suspect that you expanded the memory on the A2620 card from 2 MB to 4 Mb because I think that you do not see the error with 2 Mb. I got this from somebody at Commodore when I mentioned the problem about a year ago. They claimed and I believe them that this error does not affect ANYTHING else. What you have to be sure of is that if you want to boot up in 68000 mode that you cycle the power so that everything is flushed from memory. Anything else and you can have problems.

I sold my 68020 board out of my A2500 to a friend of mine. When he holds the buttons down he gets "Out of Autoconfig memory space" or something like that. I can't remember exactly what it was. The A2620 (With 2 Meg of Fast RAM) works perfectly on my system with A2090A hard drive controler in slot 1 (closest to the CPU slot). His system has an A2091 in slot 1. I thought that the problem might be due to the fact that the 2 Meg of Fast RAM tries to Autoconfig into the same memory area as the A2091, but I could be wrong. >Oh - Forgot to mention.

(BTW: Some stuff doesn't work with the A2620 or A2630 in place, even if you switch back to 68000 mode. Titanics music trax #1 and the new Enigma demo seem to be a few examples.) >Do you? I have no answers. I think that Dave Haynie might be able to answer our questions, since he is the guy who designed the A2620. (I think he did, looking at the circuit diagrams for it.) Then again, it may be a software fault in the ROMs and someone else could be responsible. Any comments Dave?

On my system it worked, but on HIS, he gets a "Memory Configuration >Error" when he does a reboot holding the two mouse buttons. It sounds like he may need a ROM update to prevent that. Some of the code in the ROMs was rather naieve about autoconfiguration way back then. >When he gets the error here, it still seems to work, but not as well as it >should. >When he operates in 68000 mode, programs which USED to work no longer do >100%. A few games screw up etc. He blames me. I don't have an answer. The errors reported by the A26x0 ROMs shouldn't have any bearing on the system's operation under AmigaOS. Unless the software is coming up wrong, you're either running on a 68000 or you're not, there's no in-between, as you seem to be implying here. One word of advice -- don't power up the OS with the 68020 in charge, then switch to 68000 with a keyboard reset and expect everything to work correctly. The Amiga OS will build an Exec up with the 68020 considered as the host CPU. When you do a keyboard reset, you'll more that likely be doing a warm boot, Exec isn't rebuilt, and you fire up the 68000 with the OS still thinking it's on a 68020. That could cause a few things to fail. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "That's me in the corner, that's me in the spotlight" -R.E.M. #! rnews 1722 Relay-Version: version B 2.10.3 4.3bsd-beta 6/6/85; site cbmvax.com

Well, the memory on the 2620 gets tested when you reboot. Does that help? Kris +-----------------------------------------------------------------------------+ |Kriston J.

Does your friend happen to have an early German A2000 ? ie. - no monochrome composite output port on the back ? I know that these were sold in Europe and Canada where A2000's were available earlier. If he does have an early German A2000, I believe the 68000 processor must be removed to use the Commodore 68020 or 68030 card.

I don't want to contradict Carolyn but I have the same experience with my 2620 and I talked to Dave H. about it. He says (and I believe) that the problem with the error message is that the version of ROMS is not current and they have a problem with autoconfig memory. It does NOT cause any problems however. The problem with compabitility is because switching from 68020 to 68000 modes with a warm reboot really is not kosher. If you want to do this for game/etc compatibility you MUST power the machine down and cold boot into 68000 mode. You can go to 68020 mode with a warm boot however. Hope this is useful.
