74The installation program needs to know which disk to consider
75the root disk.  Note the unit number may be different than
76the unit number you used in the standalone installation
77program.
78
79Available disks are:
80
81__getrootdisk_1
82	_DKDEVS=`md_get_diskdevs`
83	echo	"$_DKDEVS"
84	echo	""
85	echo -n	"Which disk is the root disk? "
86	getresp ""
87	if isin $resp $_DKDEVS ; then
88		ROOTDISK="$resp"
89	else
90		echo ""
91		echo "The disk $resp does not exist."
92		ROOTDISK=""
93	fi
94}
95
96labelmoredisks() {
97	cat << \__labelmoredisks_1
98
99You may label the following disks:
100
101__labelmoredisks_1
102	echo "$_DKDEVS"
103	echo	""
104	echo -n	"Label which disk? [done] "
