+# Disk geometry and partition layout tables. 
+# Key:
+#      dt      controller type
+#      ty      type of disk (fixed, removeable, simulated)
+#      d[0-4]  drive-type-dependent parameters
+#      ns      #sectors/track
+#      nt      #tracks/cylinder
+#      nc      #cylinders/disk
+#      sc      #sectors/cylinder, nc*nt default
+#      su      #sectors/unit, sc*nc default
+#      se      sector size, DEV_BSIZE default
+#      rm      rpm, 3600 default
+#      sf      supports bad144-style bad sector forwarding
+#      sk      sector skew per track, default 0
+#      cs      sector skew per cylinder, default 0
+#      hs      headswitch time, default 0
+#      ts      one-cylinder seek time, default 0
+#      il      sector interleave (n:1), 1 default
+#      bs      boot block size, default BBSIZE
+#      sb      superblock size, default SBSIZE
+#      o[a-h]  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
+#      t[a-h]  partition types (filesystem, swap, etc)
+#      b[0-1]  primary and secondary bootstraps, optional
+#
+# All partition sizes contain space for bad sector tables unless
+# the device drivers fail to support this. Smaller disks may
+# not have all partitions and all disks have no defaults for
+# the `h' partition. The strategy here is that `a' always
+# has the same amount for all disks (currently 65536 sectors or 32megs).
+# The `b' partition is approx 48 megs while `c' is always the entire disk.
+# The  sum of `d', `e', and `f' is equal to `g' which is everything else.
