Although the MBR is installed at the front of the disk, it reads from other locations on the disk (to load the PBS). The PBS in turn reads 9load. Both the MBR and the PBS need to support LBA offsets if you are going to put the Plan 9 partition far into the disk. The difference between the two is that Jim managed to fit *both* CHS and LBA into the Plan 9 /386/mbr, but there was no way to fit both into the PBS (hence the separate /386/pbs and /386/pbslba). lawrence: > 1.

My memory could be faulty. I have since > switched to a 1 GB FAT32 to work around that. Installing the Plan 9 MBR should have been able to work with a Plan 9 partition many GB into the disk. Without poking at your system I can't answer why it didn't in your case. Russ
