39.Sh NAME
40.Nm rd
41.Nd
42.Tn CS/80
43disk interface
44.Sh SYNOPSIS
45.Cd "rd* at hpibbus? slave?"
46.Sh DESCRIPTION
47This is a generic
48.Tn CS/80
49disk driver.
50Only a small number of possible
51.Tn CS/80
52drives are supported,
53but others can easily be added by adding tables to the driver.
54It is a typical block-device driver; see
55.Xr physio 4 .
56.Pp
57The script
58.Xr MAKEDEV 8
59should be used to create the
60.Nm rd
61special files; consult
62.Xr mknod 8
63if a special file needs to be made manually.
64.Sh DISK SUPPORT
65The driver interrogates the controller
66to determine the type of drive attached.
67The driver recognizes the following drives:
687912, 7914, 7933, 7936, 7937, 7945,
69.Tn 757A/B ,
70.Tn 7958A/B ,
71.Tn 7959B ,
727962, 7963, 9122, 9134, 7912, 7936,
73and 9122,
74not all of which have been tested.
75Special file names begin with
76.Sq Li rd
77and
78.Sq Li rrd
79for the block and character files respectively. The second
80component of the name, a drive unit number in the range of zero to
81seven, is represented by a
82.Sq Li \&?
83in the disk layouts below. The last component of the name is the
84file system partition
85and is designated
86by a letter from
87.Sq Li a
88to
89.Sq Li h
90which also corresponds to a minor device number sets: zero to seven,
91eight to 15, 16 to 23 and so forth for drive zero, drive two and drive
92three respectively
93(see
94.Xr physio 4 ) .
95The location and size (in sectors) of the
96partitions for these drives:

251.El
252.Pp
253The eight partitions as given support four basic, non-overlapping layouts,
254though not all partitions exist on all drive types.
255.Pp
256In the first layout there are three partitions and a ``bootblock'' area.
257The bootblock area is at the beginning of the disk and holds
258the standalone disk boot program.
259The
260.Pa rd?a
261partition is for the root file system,
262.Pa rd?b
263is a paging/swapping area, and
264.Pa rd?g
265is for everything else.
266.Pp
267The second layout is the same idea,
268but has a larger paging/swapping partition
269.Pq Pa rd?d
270and
271a smaller ``everything else'' partition
272.Pq Pa rd?h .
273This layout is better for environments which run many large processes.
274.Pp
275The third layout is a variation of the second,
276but breaks the
277.Pa rd?h
278partition into two partitions,
279.Pa rd?e
280and
281.Pa rd?f .
282.Pp
283The final layout is intended for a large, single file system second disk.
284It is also used when writing out the boot program since it is the only
285partition mapping the bootblock area.

296An unrecoverable data error occurred during transfer of the
297specified block on the specified disk.
298.El
299.Sh BUGS
300The current disk partitioning is totally bogus.
301.Tn CS/80
302drives have 256 byte sectors which are mapped to 512 byte
303``sectors'' by the driver.
304Since some
305.Tn CS/80
306drives have an odd number of sectors per cylinder,
307the disk geometry used is not always accurate.
308.Pp
309The partition tables for the file systems should be read off of each pack,
310as they are never quite what any single installation would prefer,
311and this would make packs more portable.
312.Pp
313A program to analyze the logged error information (even in its
314present reduced form) is needed.
315
