unfortunately, sashz helped me a lot indeed, but mainly in working out the build system to be able to build the whole thing, so I didn't sent him much things while I was working ... btw I have a bakup of the files I had edited in the builder so I hope it won't be too long to have another dev environement up and running again (now need to make some room on my laptop to set it up, as I won't be using a pdax86 image located on an external hard drive anymore ...that's how I did lose everything ... having all my dev environment on a REV cartridge and VMware f***ing everything :/)
BTW, i really hope to have it up and running again very soon so i'd be able to produce a few more betas and send all my work to sashz (I must admit I didn't sent him anything before my crash because, knowing he's very busy with the pdaXrom dev, I wanted to give him something polished which wouldn't need any further work from him)
edit : as of programmers using pdaXrom, 2 of them helped a little bit but one of them don't have a c3000, while the other one finally switched to openBSD after giving me the pivot_root idea.
edit2 : (status update ) i'll try to work my next beta with a 2.6 kernel based bootstrap using kexec to load pdaXrom, which could allow us to have some real multi-boot as being able to load any kernel at boot time (still have to make some tests though ...)
edit3 : if anyone want to speed up the process to a next beta, please someone try to compile a 1.1.0beta2 kernel for c3000 as I still have everything I need to work on making an image, but won't have time to set up a new dev environment (freeing space etc ...) before my next holidays, while I could work during my little free times in the meanwhile on a new beta image if I had a working 1.1.0beta2 kernel
