I was running 6.0.5 on a 4Mb SE, somewhere around 1Mb used by the system, no problem. I bought an LC. Installed 6.0.7 on the hard disk and booted up. System used about 1Mb, as before, which made things a little tight on a 2Mb machine. I bought 10Mb RAM for the LC (just for fun :-). Installed fine, booted up. WHOA! 3Mb used by the System! What the hey?? Since then I have upgraded to 7.0. It occupies 3Mb of RAM. I have tried switching off *everything* that could be switched off, and it *still* occupies 2.5Mb! Any ideas as to what might be causing this and how I can make my system go on a diet? Thanks in advance. -- See ya Nigel. ---------------------------------------------------------------------- Nigel Stanger, Internet: stanger@otago.ac.nz c/o University of Otago, P.O.

I had the very same reaction when I started running System 7.0 and then I realized that I was still running TMON Pro in "robust" mode. This took up nearly another Meg all by itself. If you truly have *everything* switched off, then get rid of fonts and sounds, because they certainly will eat up huge gobs of RAM. Also, try removing the bitmap fonts from you system file for those fonts for which True Type fonts exist. If you really need to trim the system, dump the True Type fonts and install only a couple of sizes of the bitmap fonts. Good Luck. My current plan is to buy some 4 MEG SIMMs. - Ed Rotberg -

In that mode, your system cannot access more than 8 Meg of memory. Any extra is charged to the system, although in fact it's not used. So your system is using 1 Meg, ignoring another 2, leaving 7 for your apps. Open the "Memory" control panel and turn on 32-bit addressing. (If there's no control for this, then the LC can't do it - but I think it can.) Restart your machine. You should now find that the "missing" two megabytes are available for use. There's a price to pay for running in 32-bit mode: lots of old apps aren't "32-bit clean" and will bomb in 32-bit mode. (So make backups, then experiment cautiously.) That's why it's an option whose default is "off". Contact the companies that made the incompatible apps to ask about upgrades. Hope this helps. ========================================================================== Rick Holzgrafe | {sun,voder,nsc,mtxinu,dual}!apple!rmh Software Engineer | AppleLink HOLZGRAFE1 rmh@apple.com Apple Computer, Inc. | "All opinions expressed are mine, and do 20525 Mariani Ave. MS: 3-PK | not necessarily represent those of my Cupertino, CA 95014 | employer, Apple Computer Inc."
