Full access under Linux may provide a better means of hacking Sony’s beloved PS3 too. Follow the source and read on to see where graf’s at, seems promising…

My approach will enable OtherOS to have the same access rigths as GameOS, it means access to Dispatcher Manager, Update Manager, VFLASH, HDD encryption/decryption, isolated SPUs and RSX of course.
GameOS is only good for games, for PS3 development and hacking is Linux or FreeBSD with GameOS rights are a lot better. And i want a clean approach for booting Linux, not like AsbestOS, it’ not very clean.
I have my loader for OtherOS bootloader ready now, will patch HV today and try it out in the evening, after that will report back. Stay tuned.

graf_chokolo, I don’t think you “get” AsbestOS. It’s just a linux bootloader, in fact it would work great as otheros.bld or any other way of running it as an lv2 binary, and it’s more robust than petitboot (and smaller and easier to modify).
OtherOS + extra rights isn’t a replacement for AsbestOS, it’s an alternative to our original approach of replacing lv2 with AsbestOS. There’s already one released way to boot AsbestOS (USB exploit, which isn’t very clean/handy), Hermes is working on a runtime lv2 bootstrap for it (also not very clean but handy for people who like CFWs), there’s the lv2 replacement that we demoed but which isn’t out yet (which is clean, though can’t dual-boot GameOS yet), and once you release what you’re working on you will be able to just boot AsbestOS with it. Of course you could just run petitboot too, but where’s the fun in that? (we could’ve just used petitboot as a lv2 kernel for the 27c3 demo too, but AsbestOS is just much easier to make work and I already have a working new boot ABI using the devtree to pass the region1 allocation to Linux and patches that make it work regardless of whether the bootmem split is 128/128 or 16/240).
This isn’t a competition, I see no reason why AsbestOS can’t work great with whatever you’re getting ready
Btw, re: disk encryption, they use the same key and a NULL IV (can’t remember if all 00 or all ff) for every sector. It’s a very stupid/insecure block encryption scheme. There are flags for the sector read commands to toggle encryption on and off, that’s what we used to boot Linux off of a raw, totally DOS formatted disk with no encryption or lv1 regions.
Also, we thought about booting an unencrypted lv2 kernel too (I assume you’re messing with default.spp?) but we were very short on time and self was easier. Of course, you know a lot more about lv1 than we do
