That must be the problem when you have a DOS partition, too. (btw, I put it first as that is what the installation did, just following suite :) When you have a DOS partition (using the standard installation) and there is a panic dump, it dumps to device 1 offset 0 (most distressing). Thanks Julian! I'll change mine on my next install. Dave S.
