This is the documentation for the "Update Modules" (Update Drivers)
|
||
|
|
feature.
|
||
|
|
|
||
|
|
This feature aims to propose new modules or replacement modules for the
|
||
|
|
install. This is useful when there is a firmware update for a given
|
||
|
|
driver, an additional driver needed for something, etc.
|
||
|
|
|
||
|
|
|
||
|
|
You must use a floppy disk with e2fs filesystem (NOT vfat/windows
|
||
|
|
formatted). Use "mke2fs /dev/fd0" on your own box to format a floppy with
|
||
|
|
e2fs filesystem.
|
||
|
|
|
||
|
|
This disk may contain a number of kernel modules on the root (e.g. not in
|
||
|
|
a subdirectory); some of them may replace existing modules, some of them
|
||
|
|
may be added. This disk must contain a special file, named "to_load", on
|
||
|
|
the root (not in a subdirectory). This file will contain a series of
|
||
|
|
module names, with optional module options; the program will try to load
|
||
|
|
all these modules one after another, using file on the floppy if present,
|
||
|
|
else using file within standard module repository ("marfile" on the boot
|
||
|
|
floppy). It can contain comments, these are strictly defined by the
|
||
|
|
presence of a hash (#) character on row 0 of any line. Beware, on the
|
||
|
|
first line of the line, a comment is mandatory (there is a bug somewhere).
|
||
|
|
|
||
|
|
|
||
|
|
Here's a typical scenario:
|
||
|
|
|
||
|
|
|
||
|
|
1. Boot the floppy (or cdrom) with the option "updatemodules"
|
||
|
|
|
||
|
|
(you may do that by pressing F1 then entering "linux updatemodules")
|
||
|
|
|
||
|
|
|
||
|
|
2. At the very beginning of the User Interface, you are asked to insert
|
||
|
|
the Update Modules disk. Insert the Update Modules disk and press
|
||
|
|
Enter.
|
||
|
|
|
||
|
|
--=----=----=----=----=----=----=----=----=--
|
||
|
|
Our example disk contains:
|
||
|
|
|
||
|
|
[root@obiwan mnt]# ll floppy/
|
||
|
|
total 77
|
||
|
|
drwxr-xr-x 2 root root 12288 Jul 26 12:02 lost+found/
|
||
|
|
-rw-r--r-- 1 root root 9051 Jul 26 12:43 msdos.o
|
||
|
|
-rw-r--r-- 1 root root 13660 Jul 26 12:04 ppa.o
|
||
|
|
-rw-r--r-- 1 root root 54 Jul 26 12:46 to_load
|
||
|
|
-rw-r--r-- 1 root root 32108 Jul 26 12:04 uhci.o
|
||
|
|
-rw-r--r-- 1 root root 6572 Jul 26 12:04 wacom.o
|
||
|
|
[root@obiwan mnt]# cat floppy/to_load
|
||
|
|
# Update Drivers description file
|
||
|
|
3c59x
|
||
|
|
# fat is a dep for msdos
|
||
|
|
fat
|
||
|
|
# updated msdos (handling of 9+4 filenames)
|
||
|
|
msdos
|
||
|
|
ppa
|
||
|
|
[root@obiwan mnt]#
|
||
|
|
--=----=----=----=----=----=----=----=----=--
|
||
|
|
|
||
|
|
|
||
|
|
3. The program reads the special file "to_load" and processes the files.
|
||
|
|
|
||
|
|
a- 3c59x loaded from the marfile on the boot floppy
|
||
|
|
b- fat loaded from the marfile on the boot floppy
|
||
|
|
c- msdos loaded from the update modules floppy
|
||
|
|
d- ppa loaded from the update modules floppy
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Beware, the dependencies are not handled automatically in the case of load
|
||
|
|
from the update modules floppy, that's why on our example we need to load
|
||
|
|
"fat" from the standard modules before "msdos" from the update floppy.
