MINIBIAN image for Raspberry Pi
MINIBIAN is a MINImal RaspBIAN-based Linux image for Raspberry Pi
The main focus is to have a small, updated and stable distribution that is fully compatible with official Raspbian image, without GUI and unneeded tools. So this image is perfect for embedded projects, or wherever you need to use all RPi resources for your specific tasks. The main advantage is that MINIBIAN has a very small footprint, boots in some seconds and uses just few of precious RPi RAM. Unlike other similar projects, MINIBIAN has not been obtained purging unneeded packages from original image, neither recompiling the source code: it’s just a customized Raspbian installation obtained from the same repository used for official RPi image. So kernel and binary files are exactely the same you will find on standard image, with the difference that MINIBIAN fit on 1GB SD Card, is fastest, and updated more often. -

Debian 11 Mate
Debian Bullseye with the Mate desktop environment
EFI SUPPORT: Download the efi iso if you need efi support here: https://sourceforge.net/projects/debian-mate/files/current/ This is debian 11 mate. Built with debian tools, packages, and currently based on the stable branch (Bullseye). Here I try not to use software from outside of the debian repositories. For all intents and purposes, this is just debian paired with the mate desktop environment with a lot of hardware support taken care of. Debian mate doesn't force you into new conformancy. We use the mate desktop environment here; no gnome 4 or unity for anyone. With a start menu and a taskbar, you're good to go. This is just another decent desktop use operating system, but better. Take a good long stare at my packages (check readme.txt). -

Live CD With Zerofree Utility i686 32Bit
A Custom Puppy Linux Live CD With Zerofree Utility i686 32 Bit
After Booting with this Live CD, just click on the CDROM icon on the Desktop, to open its folder contents, then Right Click the zerofree.sh file and Choose the "Run in Terminal" option and then follow the instructions shown on the terminal. As you may be aware, Booting with a Live CD, requires that you need to change the Boot Order on your System / Guest BIOS, quickly on startup, by pressing either F2 OR F12 OR F10 OR an equivalent key and then change the Boot Order to boot from the CDROM first. Some Hints: Puppy Linux Live CDs show some dialogs / settings window on first startup / first shutdown. Feel free to dismiss / close them, if you do not want to make any changes, to the live cd's operation, next time, on the same system. This will not affect the zerofree's work in any way. Apart from this, using the Internet Browser, built in, would require a Free Memory of 1 GB or more, for better Performance ( as it is generally a memory intensive activity )
