hwinfo [debug=deb_flag] [log=log_file] [list[+]=hw_item] [[+|-]probe_option1] [[+|-]probe_option2] ...
9
- probes for nearly everything
12
- probes for everything
15
- default probing, output is written to hw_log
16
*** Please don't use "hwinfo >some_log 2>&1" to store the output into a
20
- probe for ide drives only
22
hwinfo +all -isapnp -floppy
23
- probe for everything *except* isapnp and floppies
25
Some probing flags do not stand for complete modules but enable additional
26
features; e.g. "pci.range" or "cdrom.info".
30
gives a list of all cdrom's
32
hwinfo -all +cdrom.info
33
additionally reads the iso9660 info
35
To get a list of all supported probing flags, call 'hwinfo -all'.
38
2. Environment variables/kernel cmdline parameters
39
==================================================
41
You can control the hardware probing using the environment variable
42
"hwprobe" and the kernel cmdline parameters "hwprobe" & "x11".
44
If "hwprobe" is set on the kernel cmdline, the environment variable
45
"hwprobe" is ignored. Otherwise, the meaning of both is exactly the same.
48
- Controls the X server/X version to prefer. It is either "3" or "4" or the
49
name of the X server/X server module to use (XF3: server name without
50
the leading "XF86_", XF4: the server module name).
54
o prefer XFree86 3.x over 4.x (if possible)
57
o use the XF86_SVGA server (*** Even if the server does not
58
support the card! ***)
61
o use the XF4 nv_drv.o driver (*** Even if the module does not
62
support the card! ***)
65
- Controls which probing flags should *always* be set/cleared. (These
66
settings *cannot* be overridden by command line switches.)
70
o *never* do any isapnp probing
72
hwprobe=-braille,-modem
73
o don't look for braille displays & modems
75
- Allows you to add and remove hardware from the probing results. In this case
76
the syntax is (-: remove, +: add at end of list, <nothing>: add at begin of
78
hwprobe=[+-]<device_class>:<vendor_id>:<device_id>[:<unix_device_file>]
80
<device_class>, <vendor_id> and <device_id> are device ids as used by libhd.
81
See the output of hwinfo for examples. In connection with "-", you can use
82
"*" as a placeholder that matches every id.
84
Note: <unix_device_file> is optional.
86
Note2: you cannot usefully *add* hardware that needs more info than that
87
given by the hwprobe entry. Disks & floppies are notable examples.
88
(But you can *remove* them.)
90
Here is a typical hwinfo output for a mouse, with the relevant ids
91
underlined (<device_class> is the combined base_class & sub_class),
92
[see 1st example below]:
94
14: PS/2 00.0: 10500 PS/2 Mouse
95
^^^^^ --> <device_class>
96
[Created at mouse.110]
97
Vendor: s0200 "Unknown"
99
Model: 0002 "Generic PS/2 Mouse"
101
Device File: /dev/psaux
102
^^^^^^^^^^ --> <unix_device_file>
104
XFree86 Protocol: ps/2
106
Attached to: #8 (PS/2 Controller)
110
hwprobe=+10500:s200:2:/dev/psaux
111
o add a ps/2 mouse [at the end of the hardware list]
113
hwprobe=10500:s200:2:/dev/psaux
114
o add a ps/2 mouse [at the start of the hardware list, so it
115
is our default mouse]
117
hwprobe=+10b00:s5001:0:/dev/ttyS0
118
o add a braille display connected to /dev/ttyS0
120
hwprobe=-10500:s200:2:/dev/psaux
121
o remove ps/2 mice attached to /dev/psaux
123
hwprobe=-10500:s200:2
124
o remove all ps/2 mice
127
o remove all ps/2 mice
129
hwprobe=-*:*:*:/dev/hdc
132
hwprobe=+401:1274:5000
133
o add an ensoniq sound card
135
Grafics cards are are slightly trickier:
138
o add a Fire GL1 card
139
Note: this way you'll get a multihead config. You'll probably
140
rather want the following example.
142
hwprobe=-300:*:*,+300:1014:b7
143
o remove all graphics cards; then add a Fire GL1 card
146
o add a 3fx voodoo card (Note the class "400", not "300"!)
