Installation manual

4. 16. Thinkpad Control Tools 23

/etc/modutils/lvm:

alias block−major−8 off # SCSI disks

alias block−major−33 off #3rd IDE controller

alias block−major−34 off #4th IDE controller

Updating /etc/modules.conf:

#> update−modules

Note: Wehav e to be careful about the block-major-8 entry and should probably remove it, if we want to access

IEEE1394 FireWire hard disks.

4. 15. APM (Suspend & Hibernate)

Thanks to our acrobatics while partitioning the hard disk, everything works nowout of the box. However, with

such a large amount of RAM to write to or read from disk, shutting down the machine and rebooting is likely to

be quite a bit faster than hibernating.

Kernel conﬁguration for APM:

—— General Setup ——

yes Power Management support

yes Advanced Power Management BIOS support

yes Enable PM at boot time

yes Make CPU idle calls when idle

yes Enable console blanking using APM

yes RTC stores time in GMT

yes Allow interrupts during APM BIOS calls

Note: The last option “Allowinterrupts during APM BIOS calls” is required for APM to work on out Thinkpad.

4. 16. Thinkpad Control Tools

There exists tpctl, a nifty package with a suite of small programs, which let us talk directly to some of the hard-

ware in our Thinkpad.

Debian packages for Thinkpad control tools:

thinkpad−base

thinkpad−source

tpctl

No special conﬁguration is necessary for the Thinpad kernel-modules. Weonly need to unpack the tar-ball, re-

compile the kernel, install it and then try to ﬁnd out what all those nice options in (n)tpctl really are for.

Compiling and installing the Thinkpad kernel modules:

#> cd /usr/src

#> tar xzf thinkpad.tar.gz

#> cd kernel−source−2.4

#> make−kpkg −rev Custom.1 kernel_image

#> make−kpkp −rev Custom.1 modules_image

#> cd ..

#> rm −rf /lib/modules/2.4.18

#> dpkg −i kernel−image2.4.18_Custom.1_i386.deb

#> dpkg −i alsa−modules−2.4.18_0.9+beta12+3+p0+Custom.1_i386.deb

#> dpkg −i thinkpad−modules−2.4.18_3.5−1+Custom.1_i386.deb
