43.Sh NAME
44.Nm rd

46.Tn CS/80
47disk interface
48.Sh SYNOPSIS
49.Cd "rd* at fhpib? slave?"
50.Cd "rd* at nhpib? slave?"
51.Sh DESCRIPTION
52This is a generic
53.Tn CS/80
54disk driver.
55Only a small number of possible
56.Tn CS/80
57drives are supported,
58but others can easily be added by adding tables to the driver.
59It is a typical block-device driver; see
60.Xr physio 4 .
61.Pp
62The script
63.Xr MAKEDEV 8
64should be used to create the
65.Nm rd
66special files; consult
67.Xr mknod 8
68if a special file needs to be made manually.
69.Sh DISK SUPPORT
70The driver interrogates the controller
71to determine the type of drive attached.
72The driver recognizes the following drives:
737912, 7914, 7933, 7936, 7937, 7945,
74.Tn 757A/B ,
75.Tn 7958A/B ,
76.Tn 7959B ,
777962, 7963, 9122, 9134, 7912, 7936,
78and 9122,
79not all of which have been tested.
80Special file names begin with
81.Sq Li rd
82and
83.Sq Li rrd
84for the block and character files respectively. The second
85component of the name, a drive unit number in the range of zero to
86seven, is represented by a
87.Sq Li \&?
88in the disk layouts below. The last component of the name is the
89file system partition
90and is designated
91by a letter from
92.Sq Li a
93to
94.Sq Li h
95which also corresponds to a minor device number sets: zero to seven,
96eight to 15, 16 to 23 and so forth for drive zero, drive two and drive
97three respectively
98(see
99.Xr physio 4 ) .
100The location and size (in sectors) of the
101partitions for these drives:

256.El
257.Pp
258The eight partitions as given support four basic, non-overlapping layouts,
259though not all partitions exist on all drive types.
260.Pp
261In the first layout there are three partitions and a ``bootblock'' area.
262The bootblock area is at the beginning of the disk and holds
263the standalone disk boot program.
264The
265.Pa rd?a
266partition is for the root file system,
267.Pa rd?b
268is a paging/swapping area, and
269.Pa rd?g
270is for everything else.
271.Pp
272The second layout is the same idea,
273but has a larger paging/swapping partition
274.Pq Pa rd?d
275and
276a smaller ``everything else'' partition
277.Pq Pa rd?h .
278This layout is better for environments which run many large processes.
279.Pp
280The third layout is a variation of the second,
281but breaks the
282.Pa rd?h
283partition into two partitions,
284.Pa rd?e
285and
286.Pa rd?f .
287.Pp
288The final layout is intended for a large, single file system second disk.
289It is also used when writing out the boot program since it is the only
290partition mapping the bootblock area.

301An unrecoverable data error occurred during transfer of the
302specified block on the specified disk.
303.El
304.Sh BUGS
305The current disk partitioning is totally bogus.
306.Tn CS/80
307drives have 256 byte sectors which are mapped to 512 byte
308``sectors'' by the driver.
309Since some
310.Tn CS/80
311drives have an odd number of sectors per cylinder,
312the disk geometry used is not always accurate.
313.Pp
314The partition tables for the file systems should be read off of each pack,
315as they are never quite what any single installation would prefer,
316and this would make packs more portable.
317.Pp
318A program to analyze the logged error information (even in its
319present reduced form) is needed.
