Sounds good to me. If you manage to get it all together, there's a
port leader hat here waiting for you...

Is there any alternative? If the firmware insists on loading something from an ext2 filesystem, you don't have a lot of choice. So write a tiny boot2 that lives in a tiny ext2 filesystem, and knows how to find a FreeBSD filesystem and the loader. Then you can pretend that the ext2 filesystem isn't there. 8) -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ [EMAIL PROTECTED] \\ and he'll hate you for a lifetime. \\ [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Hehhehe. :-) See, the *only* thing you need on ext2fs is /boot/*. You create a fake root with fully-populated /boot on an ext2fs, and the real root (including the kernel) on another partition. Since *loader* groks ufs, you should be ok. Actually, /kernel, /kernel.old may also reside on ext2fs, as they not used after being loaded by loader. Anyway, as the end result, your system will be running fully ufs once booted. Special care will be needed when installing/upgrading boot stuff, but... -- Daniel C.

Unfortunately no. It uses a stripped down linux kernel as firmware.
That's why I switched to work on the bootloader: the darn thing doesn't
seems to grok ufs right. It's bad because the disk/video support have to
be done from the ground up. Adding support to the Shark/acorn computers
will probably be a lot easier.

I'd really like this to happens too but right now I think that would be
near impossible. binutils 2.9.1 doesn't really support arm/elf so I'm
currently using a recent snapshot of binutils (2.9.5) with gcc 2.95.1.
I'm using a boatload of very ugly hacks to make this combitation work
with current...
As soon as the binutils crew releases something more official so that it
could be added into the tree I'll be more than happy to send pr's for
what I've got so far.

Cool! Does the NetWinder use OpenFirmware, or some other firmware
interface?

If you're interested in sharing your work, I have a DNA ('shark') here
that was loaned to the Project for just this purpose. I'd be really
interested to see your cross-build bits integrated into our tree ASAP.

Hey, good work! If you have any questions on porting the kernel, don't hesitate to contact me. I also have a fair knowledge of ARM too, although its a bit dated (the last ARM machine I owned was an ARM3). -- Doug Rabson Mail: [EMAIL PROTECTED] Nonlinear Systems Ltd.

ARM support
To whoever that may interest, I've now got a nearly working freebsd loader for the NetWinder. It currently only uses the serial console and miss internal hard driver support but work is underway for both these issues. I'm making some progress too in getting world to compile but work in this area is more slower as I've got no way to test what I compile and I'm not that at ease with most of the code. -- Stephane E.
