I am attempting to boot the Mach 3.0 micro-kernel from my Mt. Xinu Mach 2.6 root file system, using Mt. Xinu's boot program. Mach 3.0 gets as far as recognizing the devices attached to the machine, but, for some reason, can't find Mt. Xinu's unix file system. It does read the first sector of the disk properly, and figures out where the DOS partitions are, but it appears that the format of "struct evtoc" has changed or the magic number (VALID_PD = 0xCA5E600D) stored in evtoc->sanity has changed. I modified the Mach 3.0 kernel to search the whole disk for a sector that had VALID_PD at the appropriate offset and it found no such sectors. Has anyone else had this problem? Adam J.
