When a frugal installation is desired, then it is convenient to have a CreateLiveCDorDVD live disc because it can be used to install the required boot loader (either /wiki/applications/pre-installed/grub GRUB, SYSLINUX, or EXTLINUX depending on the format of the partition).
First acquire the latest, official, production version of Puppy Linux.
Installation to a ext2/3 partition
Flash tutorialInstallation to a FAT32 partition within Microsoft Windows
For example, installing to U.S.B. flash drive1. Download syslinux from kernel.org
("http://www.kernel.org/pub/linux/utils/boot/syslinux/")
2. Download latest Puppy Linux .iso
("http://puppylinux.org/main/index.php?file=Download%20Latest%20Release.htm")
3. You need a file archiver like 7-Zip ("http://www.7-zip.org/download.html")
4. Clean up the U.S.B. flash drive and back up its contents.
5. Extract the contents of the Puppy .iso file to the U.S.B. flash drive using e.g. 7-zip
(it's important that the original file names will be kept, sometimes the archivers mess up with the names e.g. PUP_434.SFS instead of pup-434.sfs)
6. Extract syslinux to your hard disk drive. Using the Windows cmd, cd to your syslinux folder (e.g. C:/syslinux/win32/)
enter in cmd "syslinux.exe -m -a X:" (where X: is your U.S.B. flash drive).
You have now a bootable U.S.B. flash drive.
7. On your U.S.B. flash drive rename the file "isolinux.cfg" to "syslinux.cfg".
You can delete "isolinux.bin", you won't need it.
8. Edit "syslinux.cfg" in a text editor
at the line "append initrd=initrd.gz pmedia=cd"
change "pmedia=cd" to "pmedia=usbflash".
Appendix
For a frugal installation the file system is placed inside a single file, pup_xxx.sfs, which itself contains a compressed read-only ext2 file system into which the Linux "/" dir is placed, with its sub-directories inside it. There is also a pup_save.2fs file which contains an uncompressed ext2 file system. This one, called the "save file", stores any changes or additions you make to the normal file system. Upon booting, pup_save.2fs is super-imposed over pup_xxx.sfs so that one sees a complete file system. There are only two other small files: initrd.gz and vmlinuz (the kernel). Prior to Puppy Linux 4.00, zdrv_xxx.sfs was also used. Thus you can conveniently back up everything to, for example, a USB flash drive by simply copying /mnt/home/pup_save.2fs (plus vmlinuz, initrd.gz, pup_xxx.sfs) and your GRUB boot loader marker and config files to the drive. Technically though, you only need to back up the pup_save.2fs file, because the rest are all the original files from the .ISO file.A frugal installation runs faster in high-RAM computers; install is easy to upgrade; and it can be placed on a Windows FAT32 or NTFS hard drive/partition without re-partitioning it.
If however you have enough RAM for the particular Puppy version, a frugal install is better, because almost everything (i.e. everything in pup_xxx.sfs, but NOT pup_save.2fs) is loaded into RAM, therefore called from RAM, and so loads faster.
However, if you have fast newer disks and plenty of R.A.M., frugal loses its speed advantage. On a P3-1GHz machine with 1GB of RAM and UDMA5 hard disks, there is no material performance difference between a frugal install and a full H.D.D install, provided the full install is on a reiserfs partition.
On a P3-800 laptop with only a UDMA2 hard disk, there is a great deal of difference. If you have enough RAM to hold Puppy, e.g. 256MB, then the frugal install is the only way to go.
To be able to dual-boot Puppy alongside Windows without re-partitioning then the frugal install is the way to go.
For a full installation the conventional Linux file system [/, /boot, /bin, /etc, /lib, /mnt, /root, /sys, /usr, /var, etc.] is placed straight onto the partition. A full installation runs faster on low-RAM computers.
On a full hard disk install, vmlinuz is (usually) in /boot, Firefox is in /usr/bin and so forth. On a frugal install vmlinuz is outside of pup_save.2fs somewhere on the "real" file system. Firefox in frugal is also in /usr/bin, but /usr/bin itself is not directly on the disk but rather is in /initrd/pup_rw which in reality is pup_save.2fs on the disk's "real" file-system, "union'ed" into the overall Linux / directory tree in pup_xxx.sfs using special Puppy magic.
Another thing frugal installs do is copy the pup_xxx.sfs file into ram if there is enough memory, causing applications to start slightly faster. If the computer does not have sufficient RAM, it will instead mount the pup_xxx.sfs file from the HDD.
In the case that a frugal install's pup_save.2fs file is on a flash-based drive, Puppy will actually store any changes and new files you make in RAM, and only copy them to the pup_save.2fs file on the drive periodically (or when you click the "save" icon or shut down). This is to cut down on writes to the drive to extend it's life. This behavior does not happen on non-flash media (if it does you probably forgot to set the pmedia=satahd parameter when using a SATA drive).
You can place a frugal install on a pre-existing <a href="http://puppylinux.org/wikka/Win98">Win98</a> install; the pup_save.2fs (though it itself contains an ext2 filesystem) can reside on a vfat (fat32) partition, and if you are adventurous I believe even on an NTFS partition. Which is why a frugal install is also called a "coexist" install.
Not so with a full hard disk drive install: you cannot place a full install on a pre-existing vfat or NTFS partition, because these Microsoft file systems do not support Linux symlinks.
A full install is your preferred choice on a computer with not enough RAM to hold Puppy, say Puppy 2.15CE and only 192MB RAM, because programs and data can be mounted from disk with no need to occupy RAM.
