Puppy can run directly from a DVD or CD.
- acquire access to an optical disc drive that has writing capability (with the logos DVD, RW and ReWritable on the drive tray)
- acquire a DVD+RW optical disc (read Appendix 1 below)
- acquire the ISO image file of the desired GNU/Linux distribution, such as a recent Puppy version (read Appendix 2 below)
- write (burn) the ISO file to the optical disc
- Within GNU/Linux
- install a recent version of the libburn software package
- write (burn) the ISO file to the optical disc, via the command-line interface:
- Within Microsoft Windows
- ensure the optical disc is located inside its drive
- ensure that the B.I.O.S. is configured to follow the correct boot sequence (read Appendix 3 below)
- shutdown the computer and ensure that the computer is switched off
- switch on the computer
When shutting down Puppy GNU/Linux one will be offered one or more of the following options:
- create a personal storage save file with the option of selecting its preferred location.
- save any new user data (session) to one's personal save file located on any partition
- save any new user data (session) to the same optical disc from which one is running the operating system (multisession)
- use high-quality DVD+RW optical discs, such as the Verbatim brand
- D.V.D. has a superior specification relative to C.D.
- DVD+RW optical discs do not require blanking
- DVD+RW optical discs are rewritable
- optical disc archiving:
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 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.
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.
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)."
