Marcan named his PS3 Linux Bootloader on Firmware 3.41 AsbestOS, and today he has shared a video of it in action below along with the following details, to quote:

"As most of you will probably already know, I've been working on a project recently which aims to run Linux on the PS3 using the PSJailbreak exploit, effectively replacing GameOS on the fly.
I think it's gotten to the point where it's useful enough for other people to be interested, so here's something resembling an official announcement.
AsbestOS (a mineral, and meaning "inextinguishable" in Greek) is a bootloader to run PS3 Linux without OtherOS. It runs using the USB GameOS exploit (on PS3 version 3.41) from any compatible device, and any reprogrammable devices currently running the PS3 exploit can be used as long as they have enough free internal or external storage (40kB or so) to hold the loader. It is general enough that it should be useful to boot Linux given any other GameOS exploit in the future.
Currently, it only supports netbooting a kernel and no initrd (mostly due to bootmem limitations). This is enough to run a Linux system booting from an NFS share or from USB storage media. Almost everything that works under OtherOS is working.
As additional perks of running as GameOS, you also get access to a seventh SPE (needs a
kernel patch to enable) and there is clearly full access to the RSX including 3D support, although we still need to learn a few details about how that works to be able to use it.
AsbestOS is a fully independent open source payload and does not contain any code from the original PSJailbreak payload or derivatives. It is licensed under the GPLv2. Compiling it does not require any SDK tools, and it includes a script to build a fully vanilla GNU toolchain for the PS3.
If you're interested, check out the
git repository. The
README file contains information on how to run AsbestOS and how to set up kernels. Currently, ports exist for software USB AVRs (Arduino etc.), iPods, and the reference implementation for devices with a TI OMAP3, but anything currently running PSGroove or similar can be adapted with only a few lines of new code.
For the impatient or lazy folks, here's a
kernel that you can use Update: and a
stage1 binary and a
stage2 binary.
You'll probably want to change the kernel commandline options to set up your NFS root partition. This will eventually be handled by AsbestOS, but for now, open it up in a hex editor, search for HEXEDIT_THIS, and change the commandline to suit your needs (without changing the total length, of course). Do note that this kernel does not have built-in USB support, so it can only be used for NFS booting (the USB stuff is built as a module).
You can use
this filesystem as a starting point. It's a Gentoo stage3 updated to date and with PS3-specific tools installed. Keep in mind that there's no Portage tree included, so be sure to either emerge --sync or NFS mount your server's Portage tree (which is what I do).
At the very minimum, you'll want to edit the following files to configure your NFS and networking settings (or to specify USB device partitions, if you want to go that route - but you need to compile your own kernel then): /etc/fstab, /etc/hosts, /etc/resolv.conf, and quite likely a few others. This filesystem includes kernel modules for the above kernel. The root password is 'ps3′."

In order to compile asbestos.bin (that is included) it is needed compilers PS3, such as those that or ifcaro has precompiled (that is what I have used I) or those that generates ps3toolchain.
to asbestos_loader, is an application prototype that must be compiled and so you already know: you can use basic the sources of open to manager, you clear all the PPU_SRCS less main.cpp and you add syscall8.c, you put of TARGET asbestOS.elf, you clear all the PPU_LDLIBS and you leave emptinesses VPSHADER_SRCS and FPSHADER_SRCS.
The EBOOT.BIN that is generated next to the sources, can be sent from app_home when igniting the console, if in pendrive you add a folder in root “PS3_GAME”, inside you put the ICON0.PNG and valid PARAM.SFO (that you can adapt so that puts asbestOS and those things), you create a folder “USRDIR” and inside you put the EBOOT.BIN.
Also it can become of the following way: you create the folder inside “homebrew” in root of pendrive and another one of name “AsbestOS”, where you copy the EBOOT.BIN and the ICON0.PNG
In root of pendrive it is needed asbestos.bin (that are in the folder “asbestos_bin” of rar) and dtbImage-20101020.bin, kernel of Linux that you can unload here of http://marcansoft.com/transf/dtbImage-20101020.bin
With that you would have to see the pinguinos and all that: it is not possible to be gone beyond unless you can form servant TFTP, etc, but as concept sample, is worth.
The shipper uses the generic route “/dev_usb” reason why he does not agree that there are other devices FAT connected to the console.
PS: Please, that the people who do not know of these things, abstain to take part: Linux in PS3 at the moment, is but a curiosity that another thing, because it is in diapers. This that I put here is not but that a curiosity for some and others, perhaps it is a route easy of work to develop kernel in a device that in principle, is not preparation for it.
