This is a generic CS/80 disk driver. Only a small number of possible
CS/80 drives are supported, but others can easily be added by adding ta-
bles to the driver. It is a typical block-device driver; see physio(4).
The script MAKEDEV(8) should be used to create the r
\brd
\bd special files; con-
sult mknod(8) if a special file needs to be made manually.

The driver interrogates the controller to determine the type of drive at-
tached. The driver recognizes the following drives: 7912, 7914, 7933,
7936, 7937, 7945, 757A/B, 7958A/B, 7959B, 7962, 7963, 9122, 9134, 7912,
7936, and 9122, not all of which have been tested. Special file names
begin with `rd' and `rrd' for the block and character files respectively.
The second component of the name, a drive unit number in the range of ze-
ro to seven, is represented by a `?' in the disk layouts below. The last
component of the name is the file system partition and is designated by a
letter from `a' to `h' which also corresponds to a minor device number
sets: zero to seven, eight to 15, 16 to 23 and so forth for drive zero,
drive two and drive three respectively (see physio 4 ) . The location
and size (in sectors) of the partitions for these drives:

The eight partitions as given support four basic, non-overlapping lay-
outs, though not all partitions exist on all drive types.
In the first layout there are three partitions and a ``bootblock'' area.
The bootblock area is at the beginning of the disk and holds the stan-
dalone disk boot program. The _
\br_
\bd_
\b?_
\ba partition is for the root file sys-
tem, _
\br_
\bd_
\b?_
\bb is a paging/swapping area, and _
\br_
\bd_
\b?_
\bg is for everything else.
The second layout is the same idea, but has a larger paging/swapping par-
tition (_
\br_
\bd_
\b?_
\bd) and a smaller ``everything else'' partition (_
\br_
\bd_
\b?_
\bh). This
layout is better for environments which run many large processes.
The third layout is a variation of the second, but breaks the _
\br_
\bd_
\b?_
\bh parti-
tion into two partitions, _
\br_
\bd_
\b?_
\be and _
\br_
\bd_
\b?_
\bf.
The final layout is intended for a large, single file system second disk.
It is also used when writing out the boot program since it is the only
partition mapping the bootblock area.

The current disk partitioning is totally bogus. CS/80 drives have 256
byte sectors which are mapped to 512 byte ``sectors'' by the driver.
Since some CS/80 drives have an odd number of sectors per cylinder, the
disk geometry used is not always accurate.
The partition tables for the file systems should be read off of each
pack, as they are never quite what any single installation would prefer,
and this would make packs more portable.
