As far as The FAT (more likely FAT32) can be the filesystem type that each of the OSen can read/write.

I thought that the fancy MBR went in the extra track space beyond that official single sector that almost no one actually uses any more. I haven't heard of that. The RHEL and SUSE installs I did recently did not look like they were using two primaries. But I didn't make a point of looking for that, so I am not sure. ////jerry > > FreeBSD might be able to mount the CENTOS slice stuff if you use > > the right type of mount.
