Puppy Boot Parameters

This page lists some of the parameters/arguments you can set on Puppy's boot up. (Note- these don't apply to early versions of Puppy especially pre Puppy2.)
Parameters are passed to Puppy in one of two ways. Either by typing an option at the boot up screen (if Puppy is in 'live' mode), or via one of the bootloader files.
For example, if grub is being used then the menu.1st kernel line needs modifying-
kernel /slacko531/vmlinuz pmedia=atahd psubdir=slacko531

Psubdir
Specifies the subdirectory in which the kernel is located in on the boot partition. If not specified init will look in / and /boot , I'm not sure which order. As of puppy 3.00 this parameter also restricts the boot search for existing pup_save files only pup_saves inside this directory will used. This can be used to allow multiple puppy installation on the same partition to be used without risk of using the wrong one in error.
Example- psubdir=boot/puppy216


Pmedia
Specific boot device by media type.
Omitting parameter usually results in Puppy correctly detecting boot media.
Otherwise manually specify the boot media and interface using one of the following:
usbflash usbhd usbcd ideflash idehd idecd idezip satahd satacd scsihd. This would be where USB, IDE, SATA, SCSI are the accepted interfaces and flash memory, hard drive, CD/DVD drive, ZIP drive are the accepted drives.
Example- PMEDIA=idehd.
(Applies to Puppy 2.x and later).

Pdev1
Specifics boot device by partition.
For example- Pdev1=sda1

Pfix
If using multiple pfix options, separate them with a comma, e.g. pfix=rdsh,usbcard

PupSfs
Controls what file is loaded as BaseSfs. Specify full path and filename, for example
pupsfs=sdb1:/pwary/wary_511.sfs

NOPCMCIA
Add nopcmcia if you don't want the PCMCIA (PC card) drivers and card ~manager to be started during the boot process.

PKEYS
The keyboard layout for a country. Default is "us". Choices are: be br cf de dk es fi fr gr hu it jp no pl ru se uk us See Barry's recent blog post for more on this.


PupSave files
Puppy's behavior on boot up depends whether any savefiles are found:
If none are found Puppy will load the BaseSFS without any modifications. In many versions this will prompt the user to configure Puppy and ask save is required on reboot/shutdown.
If only one save is found it will load automatically.
If more than one is found the user is prompted to select via a text menu.
