Here is the information about DMA issues and the A2630/A2000/A2091. I never could get this combination to be reliable until I added the resistor mentioned in the text. It is a 10 minute 25 cent fix that really makes a HUGE difference. This worked on a Rev 6.2 2000 as well.

Jeff, got a pic of the mod? Which way do you install the resistor? I think I need to do this mod on my A2000. I get lockups on my A2630 w/2632 RAM card. I did pinpoint that it does not seem to crash when the RAM is OFF.
