I have a friend who just purchased a IIsi with 17megs o memory.. Now me being the mac guru that I am, he called me over to help him put the whole thing together... Anyway, we were playing around with the neeeto brand colors and stuff and we checked the about finder and saw that the system file was takeing up about 9347k or something, but something that was definatly HUGE... Naturally, he turned to me and asked "Why?" well, being the guru that I was, I felt that I had to give him an answer. "Why ask why? Drink bud dry" said I, and off we went for a couple of brews... Naturally my carefully planned diversion averted further threats to my guru like standing, (although it did cost me a couple of beers heheh) Anyway, Why? Just out of sheer curiousity.. We were using 256 color mode, nothing like backdrop or any other inits that would take up huge amounts like that... 40meg hard drive and no math co-processor. Thank you for your support.

With 24-bit addressing you only get 8Megs of memory. The system "hides" the rest of the memory within itself. To access physical memory beyond 8Megs (on a machine with 32-bit clean ROMs), go to the "Memory" Control Panel and enable 32-bit addressing.

Try running Sys 7 in 32-bit mode... That should solve your problems. This is related to a few other discussions floating around... The Mac can't address more than about 10 meg of memory (some people say 13, some people say 8, I'm not sure WHO'S right!) in 24-bit mode. When this happens the remaining memory is attributed to "System".

Did you have 32-bit addressing enabled? If not, then the system heap includes the system RAM plus all of the non-addressable RAM. =============================================================================== | Glenn L.

It is perfectly possible for me to run my IIX (with 10MB VM) with a total of 7,8MB of applications, leaving 2,2MB for the system software. This means that the system software not only "hides" the memory exceeding 8MB, but is in fact able to use it. So on the IIsi, the system gets 17MB - 8MB = 9MB. And then for a question: Is it able to use all of it (so you can at least play around with tons of TT fonts and other system-memory consuming stuff)?? ----------------------------------------- Espen J.

With 32bit you would have upto 4GIGA??? minus system reqs... I'd like 4 gigabytes of RAM but with my mac+ I would have to wait a day to see the extensions come up on the screen at startup!!! Say isn't there a nasty/dirty way to get 16MEG on a plus... Anybody know of any way to do a ROM upgrade to a plus? Seems scarey to me that we talk about the plus now the way we used to talk about the 256K, but times they are a changin' but I'm sticking with my plus (It's that or a Heathkit H19!!!) Sure would like to have 4GIGA though... ;-) Pink Pirate, Inc. -------------------------------------------------------- Disclaimer: I am only related to my parents.
