I'm running A/UX 2.0b9, and want to set up the virtual memory capability when running under MultiFinder. However, I can't remember which file it is I have to edit, and what to add to it, to get this to work. Can anyone refresh my memory? Also, how big can I make this? I know that with an 8Mb- real machine I can run with 16Mb virtual memory. How about with a 4Mb-real machine? Can I still set it up as a 16Mb virtual machine, or do I have some lower limit? Many Thanks & Regards, Darryl E. Marsee Syracuse University <demarsee@gamera.cns.syr.edu>

That way, I can type 'mac32 -m5m' to start a 5M Mac environment, or just 'mac32' to use the default size (the size of physical RAM). So far as I've been told, 16M is the largest Mac environment that you can run, but I'd expect that you could run that on a 4M machine with a 16M swap partition (so that you 20M virtual memory; 2-3M for the kernel, 16M for the Mac OS, and some to spare). It would probably swap enough to be very slow, but it should work. Mat

Just set the environmental variable TBMEMORY to as many bytes as you want up to 16Mb. Do it before running mac32 (eg put it in your .login) and you will get that much Finder memory. Eg setenv TBMEMORY 16000000 will give you nearly 16Mb. It makes the Virtual INIT redundant (someone said that Virtual does not work under 2.0).
