I have a mac 2cx w/ 20mb ram using mode 32 to access the ram. When I turn on vm the computer hangs on startup. The two will not work together except when running system 7.0 which is useless for me.I now run sys 7.5.5

Can you give a little history on how you upgraded to OS 7.5.5, and whether or not you removed any of the control panes or extensions so installed?

You may want to try using Extensions Manager to turn off all extensions, then select only the memory control panel, then restart.

Send a comment with the requested info, as well as if the above worked for you.

To go from system 7.1 to 7.5.5 I first went to 7.5.0 from CD, then to 7.5.3 from installer on another CD, then to 7.5.5 from floppies downloaded. I have tossed all extensions and control panels from all upgrades that I don't need, IE things for powermacs, (since I don't have one) things for apple printers and other junk, stuff for networking etc. I have used ext. manager to disable all except memory and vm is not present even though it is on in the control panel.I also left vm and 32 bit addressing on and get the hang on restart. So vm and 32 do not work together and vm does not work by itself.Just for grins I put sys 7.0 on external drive and vm works w/ mode 32 but can't use AOL 3.0 w/ sys 7.0. And get this, I took out the 4mb simms and put back the 1mb simms so I had 8mb ram and the computer says I still have 20mb.Strange. 4mb in bank a and 4mb in bank b. About extensions of course I have the ones AOL put in when I installed AOL 3.0.1, CFM68k runtime enabler(final release) and all the others.But I tossed them out and still no vm and 32 bit together.I have rebuilt desktop and zapped Pram w/ tech tool and used disk first aid and Norton disk doctor w/ no help. I have also reformatted my internal drive(fujitsu 630mb) w/ apple driver from the HD SC setup.

Maybe you use the wrong Mode 32 extension. There is one for System 7.5 or later available which you have to use. This works fine on my Mac SE/30 with RAMDoubler. I didn't try virtual memory because it was always too buggy with System 7.5.x

Yes I have the latest version of mode 32, v7.5 which I downloaded a couple of months ago when I installed sys 7.5.

Squibb, try updating your disk drivers before you install 7.5.  then, install 7.5 and that latest vesion of mode32 that you have.

Well after I re-formatted my hard drive then it was a clean plate  which I installed the system software onto. So it would seem that in effect, I have done what you suggested in your answer. Please tell me if I'm wrong.

reformatting does not mean that you updated the driver.  In apples' (hd setup) or whoever's drive utilities you use, there is an option to update the driver for the hard disk.  before you install system software, you should click on that option and then restart.  Remember, you should have the latest version of the whatever drive setup utility you use.
