# @(#)disktab 5.5 (Berkeley) 2/27/91
#
# 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-p] partition sizes in sectors
# b[a-p] partition block sizes in bytes
# f[a-p] 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.
#
# XXX - Would like :ba#4096:fa#512: but that panics...
# Leave nc=16; adjust size using: ns
