eh eh, success too.. Smile
My previous pupsave, still on the pendrive, loaded at boot.. We could we ask more... Some devs are really useful to thousands of puppy passengers, and of Mintpup of course
Isobooter should work as well with the other Debian dogs (XenialDog had untill now his own pendrive)

Just to be clear, the "pmedia" argument is used by Puppy when it starts up - it has nothing to do with ISObooter.

Different Puppies handle this argument different ways, and how it works depends on your hardware. There is no "best" option.

You need to describe your particular situation.

The two sensible choices are "pmedia=cd" and "pmedia=usbflash". They should cover all the possibilities.

Unfortunately, some hardware doesn't like USB booting, no matter how you set it up. Here's the problem:

It's the job of the computer's BIOS to locate the first two Puppy files - vmlinuz and initrd.gz. It can usually find them on the USB drive.

It then passes control to Puppy, who tries to find its SFS file on the USB drive.

On a few computers, the USB system times out between those two phases. If Puppy cannot wake up the USB, it won't be able to find the SFS file, and booting will fail.

Traditionally, the "pmedia=cd" argument tells Puppy to look in lots of places. If it can find the SFS file on a hard drive, booting may succeed.

Thanx again rcrsn51, just confirming that it is allowed 2 have Both pmedia=cd & pmedia=usbflash for each iso? in the menu.lst on the line that says kernel or root if it's chainloaded?

And can the USB system Timing be dictated in the menu.lst?

Also Wot is the Typical Error Message 4 that issue & if I could be aware of it could I add a puppy Boot Option on the Fly?

Thanx again 4 Sharing your Wisdom!

No. If you are booting with "splashscreen=n", you can have one or the other, but not both.

No. If you are booting with "splashscreen=y", you cannot use the pmedia option. For a Puppy, you are simulating booting from the CD, in which case "pmedia=cd" is already in place.

No. That is handled by Puppy.

"SFS file not found"

It is possible to edit the GRUB menu on-the-fly, but it can be awkward.

Here is the basic idea:

1. Set up your Puppy ISO with "splashscreen=n" and the default "pmedia=cd".
2. If it boots, switch to "pmedia=usbflash" in hopes of improving the boot speed.
3. If #1 fails, switch to "splashscreen=y".
4. If #3 fails, try booting off a physical CD.

Hi Rcrsn51,

I just wanted to say "Thank You" for ISObooter. I've always installed pups + ddogs + all other ubuntu/debian-based OSes either using frugal (for pups & ddogs) and/or just using a separate, single usb or dvd to dd the ubuntu/debian OSes to. I had always wondered if I could put multiple ubuntu/debian OSes on one usb stick, just in the form of their ISOs, and somehow have that ISO launch so I could run it, and if I like, install it to somewhere else. I tried Yumi, but it is/was hit or miss for me.

Then, I I came across your ISOBooter thread here, and, well, all my questions were answered. It works fantastic. I tried it first with a large number of ubuntu/debian-based distros---all the ISOs launch just as if they were launched from their own DVD). Next up, going to try a couple handfuls of Pup ISOs.


You know, the number of things in all these different pups I like to use that have your touch & imprint on is quite a bit when I sit down and think about it. I come across your name inside many scripts when I am hunting & pecking around inside the pups. Wish I had just a little of your skills so I could do something similar for the puppy community. Thanks much again Smile

Thank you for those kind words. But most of the credit for ISObooter should go to Scooby's work with Grub4Dos here.

It contains the key piece of code that makes ISObooter work - how to link the fourth entry in the partition table back into the ISO, so the distro can locate all its files.
