Boy did I do a STUPID thing today. I was fooling around with my Mac II (1 Meg RAM) while I had the Control Panel DA up. I was flipping though the various sizes of RAM cache sizes when I noticed the range was from 16K to 750K. In my fooling around I turned it on by mistake and closed the DA while the cache was set for 750K!!! Seeing my mistake I tried to open the Control Panel DA back up again....an error message comes up saying that there isn't enough memory to open the DA! At this point I'm not in a panic so I click on the continue box. Now a system bomb comes up ID=19. Now I PANIC!!!! I try a reboot from floppy...get to the desktop, but the control panel still cannot be pulled up without crashing the system. Try a reboot from hard disk....the smile mac comes up then the screen glitches and the musical tones play, not the ones on restart, the tones when you hit the interupt switch. Now I really PANIC. Next is a complete restore of all the hard disk files.....The same things happen!!! Next I try to rebuild the desktop (restart with the control/option keys down).....same thing!!!! Now what do I do!!!! I've heard the configuration ram locations must be reset sometimes....but how? Any suggestions? HELP!! HELP!! Send email direct to me.....

HELP!! >Send email direct to me..... Try: Boot without multifinder active (hold the command key down while booting) Open the control panel while holding down shift/option/command in order to zero the PRAM. Reset things the way you want them (I'd suggest less than 750K of cache in your case :-) > >Marty Lee >-- >tektronix!reed!omen!bucket!martyl (Marty Lee) -- David W.

There is a program called batteryzap that does this for the Mac II and the Mac SE. It would be nice in the next version of the system for apple to add a propeller shift combination to do this as well!

Hi, Yes, I know your problem. Something similar like that happened to me. I found out that it was the "parameter RAM" that got 'zapped!'. Either, call me (408) 447-7225, and we'll figure out how to send the program that fixes it to you (it was written by Andy Hertzfeld to fix this problem); or send me a note. Also, you can walk into ComputerWare in Palo Alto, and they have the program on their MAC II. The name is "BinaryZap". -stuart liroff (Hewlett-Packard, Cupertino)

[....] This bit me too, so the answer might be of general interest: Take or make a spare startup disk, borrow a Mac and ResEdit, open the System file, and delete the resource of type CACH (you could also delete INIT 35, or whatever it is). When you boot with this disk, you won't lose any memory to the RAM disk, and you can use the Control Panel to set the memory back down again. If you're using an older Mac, you can just install a newer Control Panel (and the General cdev, if you're going to get real recent) on an older System disk and avoid the ResEdit step. ------------------------------------------------------------------------------ Oliver Steele ...!{decvax,ihnp4}!mcnc!unc!steele steele%unc@mcnc.org "When you believe in a loving God, life appears to be very funny." -- Garrison Keillor

To reset the Parameter RAM hold down COMMAND-OPTION-SHIFT when selecting
the control panel. On the Mac II and the SE you will be asked if you want to
reset the Parameter Ram...answer yes and the RAM will be reset to factory
settings. I ran into a simmilar problem when I was using multiple hard
drives and was switching drive names and ID numbers. The Mac II got so
confused that it would only boot from floppies and would not bring any
hard disk icons up onto the desk top.
So don't panic...you haven't just killed a mac II.
P.S.: Apple really should say something in the mannuals. I found my info
in a tech note on booting tough disks.

Well after about a week I got LOTS of help from all of you out there on
USENET and I would like to extend my thanks.
To summarize my problem the ram cache on my Mac II got set to 750K and the
control panel would not let me open the control panel again to turn it off.
Also with a 750K cache there was no room for any application to run.
The final solution was:
Hold down "command", "option" and "shift" while opening the control panel.
Then I reset the "pram". Things still didn't work so I rebooted. Now the
hard disk would not boot. A total reload from the backup disks using HD
Backup did not work. The disk was initialized and reloaded.....now the moment
of truth.....the smile mac came up and then the system proceeded to trash the
disk. I then initialized the disk AGAIN. Now the HD 40 boots!!! A reload
from floppy and all data was recovered.
Lesson learned: 1) Don't mess with things just for kicks.
2) Backups are very important.
3) The APPLE manuals that come with the Mac II are very
basic and inadequaate.
4) Some people (me) just never learn :-)

When I hold down Command-Option-Shift while selecting Control Panel, I get the Control Panel -- only slower. No dialogue box, on PRAM or anything else. Anyone besides gamble done it on an SE?

Try selecting the apple menu, dragging down to Control Panel, depressing Command-Option-Shift and then releasing the mouse button. You'll get a dialog saying you are about to zap parameter ram, are sure you want to do that? On a plus, it just beeped at me, I'm guessing this just works on an SE and a II. > > >Ellen Keyne Seebacher, Univ. of Chicago Computation Center >{ihnp4!gargoyle, oddjob}!sphinx!see1 -- David W.

The first time (Ah, that first time, you never forget ... ) it did what you described, but when I pushed down the COMMAND-OPTION-SHIFT *BEFORE* opening the Apple menu instead of after (which is what I did the first time) it worked. It also works on the Mac II, but the keys can go down any time up until the mouseUp (eek! HyperTalk) occurs on the Control Panel select. - Andrew ***************************************************************************** * Disclaimer: Remember kids, we're professionals here, * so don't try this at home.
