Poof loads and boots perfectly on BlueG3, so it seems there's nothing more
It doesn't read the kernel from ext2 but from an OF-readable disk, or the
kernel may be included in poof's file.

It seems that the modified secondary quik bootloader doesn't really crashes
when using OF for raw disk access but in the middle of ext2fs'partition
opening code. And MacOS X server bootloader loads the kernel from the UFS
partition (even if the bootloader is on an HFS partition). But where is
Darwin's SecondaryLoader source code ? I've downloaded all Darwin files
containing the word "loader" but it doesn't seems to be here...
I have included an os chooser written in Forth that works with poof (you
must first install it). It's written for my configuration but it should be
easy to adapt since it's plain text and there is nothing else to do than
changing the partition numbers (and erase MacOS X from the list for those
who don't have it) To use it, you must first install poof, then copy
blueboot into an OF readable folder (like MacOS System Folder) and then
change the boot device (setenv boot-device hd:X,\\blueboot where X is the
partition number containing blueboot, usually 5 if you put it into your
MacOS System folder).
