# Disk Label for Kevin (9-Jul-99)
#
# Used the RA81 entry for a start.
#
# total sectors avail 633672 (Kevin's *second* disk drive)
# 
# Prime factors for the total count are: 2 2 2 3 3 13 677
# Assume 677 cylinders, 13 heads, 72 sectors/track
# That yields 932 sec/cylinder or 468K/cylinder
# "Generic" partitioning, we'll assume at least
#			a: 24MB root
#				(24 * 1024) / 468 = 52.xx -> 53 cylinders
#			b: 16MB Swap
#				(16 * 1024) / 468 = 35.01 -> 35 cylinders
#			c: whole disk
#				= 677 cylinders
#			g: xxxMB User (all the rest for /usr)
#				(677 - (53+35)) = 589 cyl = 269MB
#
#			Note that some prefer a /var partition too.

Put the above into /etc/disktab and type
	disklabel -w ra1 kevin

Note that since your two disks return a different number of sectors you
will have to create your own label for the ra0 drive...
