I'm running System 7.0b on a Mac IIci with 8Mb of real RAM. When I try using virtual memory [without running in 32-bit mode] to boost my available memory up a few Meg [I think 11 Mb is the limit without running 32-bit] I find the System partition swells immensely. The result is that after sacrificing 11 Mb of disk space and some speed [for swapping] I end up with a whole extra 900k or so of usable memory. What is it that the system is doing? Is it swapping a ton of code into memory to handle the virtual memory? PS: I can't run in 32-bit because QuickMail won't run. :-( Reid -- Reid Ellis 176 Brookbanks Drive, Toronto ON, M3A 2T5 Canada rae@gpu.utcs.toronto.edu || rae%alias@csri.toronto.edu CDA0610@applelink.apple.com || +1 416 446 1644

This is probably the same limitation that people run into with Virtual and Maxima from Connectix - the NuBus is geographically addressed, so each card that you have installed in the NuBus eats up 1Mb of address space. I'm not sure what happens on the IIci's 'phantom slots', but I would venture a (tenuous) guess that that address space is not available. anders
