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).
