Live Installation to External Device (Optical Disc Drive): PuppyLinux

When shutting down for the first time one will be given the option to create a personal storage save file with the option of selecting its preferred location.

When the computer re-starts it should load (start) Puppy Linux. If Puppy does not load:

ensure to follow the instructions at Appendices 1, 2 and 3

Technical Support

When running Puppy from optical disc any additional software or data may be written to one's personal save file located on any partition. If such data is desired to be stored on the same optical disc from which one is running Puppy then one would need to create a special MultiSessionLiveDVD.

Appendix 1 - Using high-quality blank media is essential

To create a live disc it is recommended to use DVD+RW discs, which are rewritable.

D.V.D. has a superior specification to CD.

Appendix 2 - Verifying the integrity of the ISO file

The downloaded container file must have the extension .iso. It is an exact copy, or image, of an existing file system. To ensure that the file is downloaded completely and without corruption use the wget command, e.g.:

wget -c /puppy-version-location/puppy-version.iso

(If wget is not used then one should verify its integrity by verifying its MD5 or SHA checksum). This ISO file may then be written to a blank optical disc using a particular software program. It is by booting up with this disc in the optical disc drive that one can run and use Puppy Linux.

Appendix 3 - Setting the correct boot sequence

For a computer to boot from a device such as an optical disc or a flash memory drive the device must be read/accessed before any other connected device such as a H.D.D.; therefore when, for example, an optical disc is in the optical disc drive at boot up it will load Puppy Linux from that drive only, and no where else, if the computer has been configured specifically to do that. If the computer does not start/boot from the live D.V.D. it will be necessary to either access a boot menu or the B.I.O.S. so that the computer is instructed to boot from the optical disc drive and not any other drive; re-starting will be necessary in conjunction with using the correct key(s) (see Appendix from here).

Being able to boot from a live D.V.D. also means that it itself may be used to boot the computer when it is not possible to do so with a flash memory drive or hard disk drive: the computer boots from the bootloader on the optical disc but loads the frugal save file (or operating system) from either the flash memory drive or hard disk drive.

Correction
Booting with pmedia=cd, Puppy only searches optical drives for vmlinuz and the main sfs (and zdrv).

...correction, the above is true if boot with 'pfix=ram'.

Otherwise, searches optical for vmlinuz, but hd and optical for main .sfs (and zdrv)."
