# Disk geometry and partition layout tables.
# Key:
# ty type of disk
# ns #sectors/track
# nt #tracks/cylinder
# nc #cylinders/disk
# rm rpm, 3600 default
# se sector size, 512 default
# sf supports bad144-style bad sector forwarding
# so partition offsets in sectors
# p[a-h] partition sizes in sectors
# b[a-h] partition block sizes in bytes
# f[a-h] partition fragment sizes in bytes
#
# All partition sizes contain space
# for bad sector tables unless the
# device drivers fail to support this.
#
# Entries may also be used for other compatible drives
# with the same geometry.
#
# SCSI disks
# Again, these mapping support three basic layouts:
# Again, these mapping support three basic layouts:
#
# A/B/G: This is the "traditional" setup for a bootable disk.
# A is the root partition, B the swap, and G is for /usr
# and users.
# A/D/E/F (large drives):
# A/D/H (small drives):
# This is a setup for bootable systems requiring more swap
# (e.g. those who need CL). It has A as the root, D as a
# larger swap, E and F (or H) as smaller user partitions.
# E could be used for /usr and F for users (or H for both).
# Or, E could be used for /var and F for /usr and users.
# C: This gives a single, non-bootable, large user filesystem.
# Good for second drives on a machine as either /usr/src
# or a large /usr or user partition.
