43.Sh NAME
44.Nm rd
45.Nd
46.Tn CS/80
47disk interface
48.Sh SYNOPSIS
49.Cd "rd* at hpibbus? slave?"
50.Sh DESCRIPTION
51This is a generic
52.Tn CS/80
53disk driver.
54Only a small number of possible
55.Tn CS/80
56drives are supported,
57but others can easily be added by adding tables to the driver.
58It is a typical block-device driver; see
59.Xr physio 4 .
60.Pp
61The script
62.Xr MAKEDEV 8
63should be used to create the
64.Nm rd
65special files; consult
66.Xr mknod 8
67if a special file needs to be made manually.
68.Sh DISK SUPPORT
69The driver interrogates the controller
70to determine the type of drive attached.
71The driver recognizes the following drives:
727912, 7914, 7933, 7936, 7937, 7945,
73.Tn 757A/B ,
74.Tn 7958A/B ,
75.Tn 7959B ,
767962, 7963, 9122, 9134, 7912, 7936,
77and 9122,
78not all of which have been tested.
79Special file names begin with
80.Sq Li rd
81and
82.Sq Li rrd
83for the block and character files respectively. The second
84component of the name, a drive unit number in the range of zero to
85seven, is represented by a
86.Sq Li \&?
87in the disk layouts below. The last component of the name is the
88file system partition
89and is designated
90by a letter from
91.Sq Li a
92to
93.Sq Li h
94which also corresponds to a minor device number sets: zero to seven,
95eight to 15, 16 to 23 and so forth for drive zero, drive two and drive
96three respectively
97(see
98.Xr physio 4 ) .
99The location and size (in sectors) of the
100partitions for these drives:

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

300An unrecoverable data error occurred during transfer of the
301specified block on the specified disk.
302.El
303.Sh BUGS
304The current disk partitioning is totally bogus.
305.Tn CS/80
306drives have 256 byte sectors which are mapped to 512 byte
307``sectors'' by the driver.
308Since some
309.Tn CS/80
310drives have an odd number of sectors per cylinder,
311the disk geometry used is not always accurate.
312.Pp
313The partition tables for the file systems should be read off of each pack,
314as they are never quite what any single installation would prefer,
315and this would make packs more portable.
316.Pp
317A program to analyze the logged error information (even in its
318present reduced form) is needed.
319
