5# Disk geometry and partition layout tables.
6# Key:
7#	ty	type of disk
8#	ns	#sectors/track
9#	nt	#tracks/cylinder
10#	nc	#cylinders/disk
11#	p[a-h]	partition sizes in sectors
12#	b[a-h]	partition block sizes in bytes
13#	f[a-h]	partition fragment sizes in bytes
14#
15# All partition sizes contain space for bad sector tables unless
16# the device drivers fail to support this. Smaller disks may
17# not have all partitions and all disks have no defaults for
18# the `h' partition. The strategy here is that `a' always
19# has the same amount for all disks. The `b' partition is
20# four times `a' while `c' is always the entire disk. The
21# sum of `d', `e', and `f' is equal to `g' which is everything else.
