I was providing a distinction between >my laptop and my other machine that I said I took the 4megs ram out of... >TTYL... Ohh...I understand what you mean now. Yes, this difference (3456 vs. 3328) ca happen when the chipset does/doesn't support remapping some of the memory that is normally lost in the ISA hole. This can be up to 384K of difference, but most chipsets only remap 256K. I think the failure cases are with the machines that *don't* do this remapping - there just isn't quite enough memory. -DG
