Your 4th partition is just outside that. Yes, this is his problem. Note that the whole partition doesn't have to be under 1G, only: o the disklabel o the a slice o any bad sectors that have been replaced in the a slice if bad144 is active. In addition, not even the *whole* a slice needs to be below that mark if the following data is below the mark: o the inode for the / directory o the inode data blocks for the directory blocks up to and including the directory entry for "kernel" o the inode for the "kernel" file o the indirect blocks (if any) for the "kernel" file o the inode data for the "kernel" file contents The limitation is caused by one of three things: 1) His BIOS does not support the LBA BIOS extension (it must be there for the other two to use it, obviously...). 2) His boot selector does not use LBA BIOS extension to load the OS boot block (OS-BS and BootEasy do not use the LBA BIOS extension). 3) His OS boot block does not use the LBA BIOS extension to load the kernel (FreeBSD's boot block doesn't use the LBA BIOS extension).
