Hi
I wanted to make a bullet proof puppy installation (don't laugh!) that is installed into flash that is read only. It's a little project of mine I keep thinking about.

In the old days, you had computers like Acorn Archimedes that would contain the OS in Rom....just switch on and go...if it crashes switch off and then back on.........ahh the golden days..........RISC os loading up from Rom...........

Can anyone advise me how I might reproduce this scenario with Puppy Linux....I could boot from a CD (which I produce using the remaster method) - this is ok but I'd rather boot from a flash based device. So I want to remaster to a flash drive and make it non writeable....like the old days of EPROM.

Can anyone help here / advise me? Thanks for your help.

Like in the good all days, where cassette tapes could be put in read only (remember?) there aree flash cards with a read only facility.
I think Sandisk has those.

I have my 4.2.1 USB Flash install set up kind of like that, only a little better, I think. The automatic periodic save is disabled and I am prompted at shutdown to save everything or not. I get full read/write ability while I'm running but have to intentionally save the pup_save file to alter the contents of the USB install. The 'save' icon on the desktop still works, of course. It's a great way to run because now I'm pretty free to install stuff and tweak away at the system and if something goes awry then I just don't save the session. That way my installation keeps getting better and better without ever really endangering its previous incarnation.

It takes only a few minutes to set things up this way and you could bypass the save prompt on shutdown and have it never save just as easily. Pizzasgood has a couple of definitive threads on this in these forums. Let me know if you can't find what you're looking for.

I just saw a comment to go in Menu|System|Puppy event manager and set 0 in the tab save session.

Hi puppians,

I have puppy4.2 SMP on usb stick. [thanks aragon!]
I turned off the periodic 'save session' in Puppy Event Manager.
The installation is done without the pup_save file that is the saving session is done directly to entire usb flash during the rebbot/shutdown - not to pup_save file.

I would like none saving session and none prompt to save sesison during the reboot/shutdown. I wish to use the save-desktop icon when I need it.
So this method does't work for me:

Shutdown script: /etc/rc.d/rc.shutdown

Shutdown script: /etc/rc.d/rc.shutdown

You could use a USB SD card reader or if you have a SD slot, no reader required. After getting it set up, set the switch to lock the card. At least I think that's the way they work. Never have used the little switch on one yet. Maybe some thumb drives have a switch, too.

There's yer classic reference, too. A switch like a (small) floppy has on it. The old IBM 8" or even 5"ers didn't have that, they were really "floppy".

Hi, I changed the shut down script as Pizzagood suggested and it shuts down without saving. Brilliant. I've got Puppy set up as I want it and don't want to worry about changing it Only thing is - when I restart it, I get the warning screen saying that X seems to have exited uncleanly.
Is this something to worry about or not? Is there something to fix?
Puppy 430, frugal install, booting off a usb stick.

Regards, Jon.

Actually, this seems to be intermittent (which is code for: it's stopped, but I don't know why ...)
So: Pizzagood rules, Puppy is great.

SD memory cards have a write-protect switch. I know because I've accidentally switched it on. It took me a while to figure out why the card wouldn't let me write to it any more. Embarassed

I have a universal SD-to-USB converter, that I bought for about $15. I plug my camera's SD memory card into it so I can read the card without having to connect the camera to my computer. It's a two-piece solution to your problem.

Appears that OP pixelblip has fallen off the edge of the earth ...
