Puppy Linux Discussion Forum

[Fractal]

My SBC doesn't have a HDD - it has a 512MB CF drive, so it's important that Puppy protects it with minimal writes.
I am using 4.2.1, because 5.x doesn't seem to want to let me use the serial port, which I need.
Here are my findings:

PMEDIA=ataflash does NOT WORK. This might be because the CF cards I am using all register as non-removable.

To force PUPMODE=13, I edited my init script in the root of initrd using the "editinit" script from Pizzagood. I added the line "PUPMODE=13" at an appropriate point to force it to use PUPMODE=13.

However, this does mean editing the init script and permanently knobbling it.

Fractal, Sylvander uses Lupu 5.2 - so it pmedia=ataflash should work (I think).

Sylvander - when you say "live CD-RW" - I assume you just burn puppy ISO to your CD-RW and boot from there. Now, I don't usually use live-CD-RW, so no guarantee that this will work. The file you would need to edit isolinux.cfg. Change the last line from "pmedia=cd" to "pmedia=ataflash". The easiest way to do this is:
a) extract isolinux.cfg from Lupu 5.2
b) edit the file as above
c) get a version of puppy that has ISOMaster in it.
d) use isomaster to replace the isolinux.cfg in the puppy iso with the one you just edited
e) save the new iso, and then burn it.

Good luck.

Job done, altered ISO file made as per your instructions.

Here's greater detail on what I did:
1. Extract isolinux.cfg file from lupu-520.iso file.
(a) Using Xfe, I navigated to the folder holding the ISO file.
(b) Clicked on the icon [in Xfe] to "Lauch Terminal" that applies to the contents of that "Active" window.
(c) Typed the first few characters of the command filemnt [e.g. filem] and hit <Tab> to complete the name of the command.
[There should be a space after the command name]
(d) Type the first few characters of the name of the ISO file = lupu-520.iso [e.g. lu], and hit <Tab> to complete the name.
(e) Hit <Enter> to activate the command upon the named file.
(f) The ISO file mounted successfully at folder = /mnt/[name of file] = /mnt/lupu-520.iso

2. Edit the file as above.
(a) Right-clicked on the isolinux.cfg file within the /mnt/lupu-520.iso folder, and copied it to a handy folder = /00
(b) Right-clicked on that file, chose "Open with...", chose "Leafpad", and the file opened in Leafpad.
(c) Edited as you'd instructed, closed the file, and saved the changes when offered.
(d) Right-clicked on /mnt/lupu-520.iso folder, and chose "unmount".
An error was reported as though it had failed, but it actually succeeded in the unmount.

3. Ran ISOMaster.
(a) Went to "Menu->Multimedia->ISOMaster", and clicked that to run it.
(b) Clicked "File->Open", and navigated to the ISO file, made sure it was selected [highlighted], and clicked the "Open" button.
(c) The ISO file opened, and all the included files were listed in the bottom window.

4. Use isomaster to replace the isolinux.cfg in the puppy iso with the one you just edited.
(a) Highlighted the isolinux.cfg file in the lower pane and clicked the "Remove" icon.
It was removed.
(b) Used the "Go back" icon above the upper pane to navigate to the /00 folder holding the edited isolinux.cfg file, highlighted the file, clicked the "Add" icon above the lower pane, it was added to the lower pane.

5. Save the new iso, and then burn it.
(a) Used "File->Save as..." to navigate to the folder location of the original ISO file, and saved it with the name lupu-520-ataflash.
The program auto-added the .iso extension.
(b) Used "Menu->Multimedia->burniso2cd" to burn the ISO image to a new CD-RW disk.

6. Still to try the new CD-RW; wish me luck.
SUCCESS!
IT WORKS!

Hi Sylvander and jamesbond,

It's good to see a job well done.
