Those of you who are missing the joys of having a true 100% support of otherOS will be delighted: developer glevand released yesterday a patched Custom Firmware that allows him to boot his PS3 Slim directly into petitboot.
For those who don’t know, petitboot is a bootloader, similar to grub on Linux, allowing you to choose which OS to boot your machine on at startup. In this case, you get the choice between OtherOS (Linux) and GameOS (regular PS3 XMB)
This opens the door to a bunch of cool things to do with your PS3.
Quoting Glevand:
Mega cool I can wakeup my PS3 with Ethernet Wake-On-LAN magic packet and if OtherOS flag is set then my PS3 slim cold boots petitboot Just like old times when we had old OtherOS
