hi, I have observed this on a MacIIfx which was upgraded from a MacII. The fx contains .. 3 cards (1 Ethernet, 2 Display cards, all Apple), right justified, ie away from the power supply. 800k Floppy (Internal). Hard disk. 4*4Mb Simms. ***PROBLEM*** System takes up > 8Mb (via "About Finder"). What's going on? No change when switching twixt MultiFinder and Finder. Cache was off. This was also the case with the installation disk, which would be a reduced System (and not using MultiFinder). The same disk (install) took ~427k System memory space on a IIci. Is System 6.05 ready for 4Mb Simms? Is the problem the memory (stuffed)? Is it hardware? I saw the same thing happen on the same machine with System 7.0a. *************** Whats Up Doc?

Your options are (in order of which I prefer) : 1) Get A/UX 2.0. Then you can use all the memory, however it's expensive and probably overkill. 2) Wait for System 7, or if you're an Apple Partner run System 7.0a9. You have to go into the Memory control panel and turn on 32-bit addressing for this to work. It does work, trust me. 3) Get a RAM disk program which is compatible with the extra RAM. They exist, but I don't know where you can find one. 4) Return the memory. -- Mark Wilkins wilkins@jarthur.claremont.edu -- ******* "Freedom is a road seldom traveled by the multitude!" ********** *-----------------------------------------------------------------------------* * Mark R.

System 6.0.5 can address 8 Mb of ram directly. While you can buy 4 Mb simms, you will need to wait for system 7.0 to address it all. The news is not all bad, however. Connectix makes an INIT called MAXIMA that allows you to use unused Nubus address space to break this limit. For every empty slot, you can address one extra megabyte. I have an FX with 20 Mb, and a video board in the rightmost slot. With MAXIMA, I can use 13 Mb with system 6.0.5. Hope this explains the weirdness.

If you have the Virtual Memory INIT installed, Paul, you will see this happening; it's just how it works. If this isn't the case, I'd suggest you reinstall from known-good original disks. -- ------------ Mark Hartman uucp: ...{spsd,zardoz,felix}!dhw68k!emmayche Internet:emmayche@dhw68k.cts.com CompuServe: >internet:emmayche@dhw68k.cts.com Applelink: N1083
