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; some of them +may replace existing modules, some of them may be added. + +Create a directory per kernel version, named from the version, for example +2.6.27-desktop586-0.rc8.2mnb. In this directory put the modules and a special +file, named "to_load". 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. It can contain comments, these are strictly defined +by the presence of a hash (#) character on column 0 of any line. + +This disk may also contain some update or new modules for installed kernels. +Those modules must be placed in directory <kernel-version>. They must be +gzipped if the installed kernel modules are gzipped. + +You may need to specify the "category" so that new modules are used correctly. +For example, a scsi module should be put in category disk/scsi so that it is +put in scsi_hostadapter and initrd. + + +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/* +2.6.27-desktop586-0.rc8.2mnb/: +total 541 +drwxrwxr-x 3 a a 1024 2009-03-09 12:09 kernel/ +-rw-rw-r-- 1 a a 547480 2009-03-09 12:04 msdos.ko +-rw-rw-r-- 1 a a 54748 2009-03-09 12:04 ppa.ko +-rw-rw-r-- 1 a a 79 2009-03-09 12:08 to_load +[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 +# ISA network card needing options +ne io=0x300 irq=7 +# New module [list_modules: disk/scsi] +a320raid +[root@obiwan mnt]# (cd floppy/2.6.27-desktop586-0.rc8.2mnb ; find -type f) +./msdos.ko +./ppa.ko +./to_load +./kernel/fs/msdos/msdos.ko.gz +./kernel/drivers/scsi/ppa.ko.gz +./kernel/drivers/usb/host/uhci-hcd.ko.gz +./kernel/drivers/usb/input/wacom.ko.gz +[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 + e- ne loaded from the marfile on the boot 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. + + +4. When system is installed, update floppy is asked again so that update +modules for the installed kernels can be copied. Then depmod is called. |
