Some lessons learned from my recent A2000 rebuild

You know... its been a long time, but I had a 2000 with PP&S 040/28 & GVP 4008 and I think that is primary reason I bought a Guru Rom for the GVP controller...

I had an A2091 with a PP&S 040 as well and it was damn slow.  Took 3 minutes or more to load a 3.5 minute stereo song into Samplitude for editing.

I eventually got a GuruROM but it didn't help much.

On the other hand, I never knew anything about changing memory priority.  How then heck do you even do that?

The 2632 is doubly annoying because it doesn't autoconfig. It has its own addmem tool which has a few extra options, one of which is adjusting the memory priority.

For other cases, there's ChangeMemPri. Worked great on my CS Mk3 a number of years ago (wanted to have the system use motherboard RAM first in order to have a larger free block  on the accelerator for Mac emulation - back in the days when I had a mere 32MB onboard).

Oh.  I used ROMTAGMEM to configure the RAM on the PP&S accelerator.  Then there was the conflict with the A2091 which would not DMA with the ram on the accelerator.

I remember that before getting the GURU-ROM, the utility vbak2091 on Aminet helped a lot with this configuration.  Maybe you should try that.
