The partition type code -> OS name translation table is hardwired into
/usr/src/sys/boot/i386/boot0/boot0.s, the source for the master bootstrap
program.  These are the current mappings:

	parition codes		string
	------------------	--------
	1,4,6,11,12,14		DOS
	99			UNIX
	131			Linux
	159,166,169		BSD
	165			FreeBSD

There isn't enough free space left in boot0 to add any more mappings.
(It has to fit in a 512 byte disk sector).  You could make space by
deleting some of the current mappings or other boot0 program features.
I suspect that you don't want to get into that.

If you want to create your own customized bootstrap menu, you might
look into /usr/ports/sysutils/grub.

If you are curious, you can find a larger partition code table in
/usr/src/sbin/i386/fdisk/fdisk.c.

For an even larger compilation, see
