Hello, I've got a rather bizarre sounding problem. I just upgraded my SE/30 to 8 meg from 5 meg. Now whenever I turn the Mac on, I get a bomb box which says there is not enough memory for the System and Extensions; that I should restart while holding the shift key down to disable extensions. It gives me two buttons: one to restart and the other to shutdown. If I press restart and let the machine restart normally (i.e., not holding the shift key down and letting the extensions load) the machine comes up fine and I see 8 meg in the About This Macintosh box. I booted of an old 6.0.3 floppy and everything came up fine; I booted the Sys 7 installation floppy and everything came up fine. I also tried turning all extensions of using Extension Manager and I still got the bomb box on power up. Note that this only occurs from a cold start -- if I choose shutdown and use the reset button on the side of the computer all comes up fine. I'm running Sys 7, without virtual memory on (though I tried turning VM on to see if it made a difference). Can anyone tell me what's going on??? Thanks in advance for any help... Oh yes, the new SIMMS came out of a IIsi; they are 100 ns and I never get a sad mac on power up so I don't there is a problem with the memory --Erik (evensen@husc.harvard.edu)

Me, too. I've got a new SE/30 with 2MB of memory, factory installed. I'm using VM (for 4M total memory). This is happening before any INITs are loaded, so far as I can tell. My 8M SE/30 at work (VM off, same set of INITs) shows no such symptoms.

... and *I* need more than 8 megabytes of CONTIGUOUS memory. The Mac's virtual memory scheme doesn't allow more than 7.7 megabyte blocks of contiguous space (at least on the IIcx). It's not real Multitasking and its not real virtual memory either. Grumble. --- John T.
