Howto setup the mouse with xorg:

# dmesg | grep -i mouse
psm0: <PS/2 Mouse> irq 12 on atkbdc0
psm0: model IntelliMouse, device ID 3

a list of drivers e.g.:

# apropos mouse | grep driver

device is psm0

# sudo cat /dev/psm0

try to move your mouse, if there are any unreadable
letters on your screen you can use this device for
your driver in /etc/X11/xorg.conf.

when there are no letters, you must check, if there
are any other FILES

# man psm | grep -i psm0
/dev/psm0   `non-blocking' device node
/dev/bpsm0  `blocking' device node under devfs.

/dev/bpsm0 is also a device, lets try the same with this
device:

# sudo cat /dev/bpsm0

Howto setup the network interface:

The network interface (if you have one built-in) is an Intel chip which will run flawlessly with the eepro100 module.
Note that LAN acticity can wake up the laptop if it was suspended but still connected.

network card config with:

sysinstall

into /etc/rc.conf:

ifconfig_fxp0="inet 192.168.2.30 netmask 255.255.255.0"
	defaultrouter="192.168.2.1"

route add default 192.168.2.1

Howto setup the soundcard:

ESS Maestro 2E PCI Audio Soundcard 16 Bit:
        http://www.freebsd.org/releases/6.2R/hardware-i386.html#SOUND
	The snd_maestro(4) driver supports the following PCI sound cards:
		* ESS Technology Maestro-1
    		* ESS Technology Maestro-2
		* ESS Technology Maestro-2E

more information: man snd_maestro

# sudo kldload snd_maestro
# cat /boot/defaults/loader.conf | grep -i loader_conf_files

check if “/boot/loader.conf” is in the variable
if yes, then next step. if no, then add it to the variable, default:

loader_conf_files="/boot/device.hints /boot/loader.conf /boot/loader.conf.local"

# sudo echo 'snd_maestro_load="YES"' >> /boot/loader.conf

save file and reboot
after reboot

the sound card should appear in your system message buffer (dmesg(8)) as something like:

# dmesg | grep -i pcm0
	pcm0:  port 0x3000-0x30ff irq 11 at device 8.0 on pci0
	pcm0:

The status of the sound card may be checked via the /dev/sndstat file:

# cat /dev/sndstat
	FreeBSD Audio Driver (newpcm)
	Installed devices:
	pcm0:  port 0x3000-0x30ff irq 11 at device 8.0 on pci0 (4p/1r/0v channels duplex default)

test your soundcard

# cat filename.mp3 > /dev/dsp

This command line should produce some noise, confirming the sound card is actually working.
Sound card mixer levels can be changed via the mixer(8) command. More details can be found in the mixer(8) manual page.

exit and compile kernel (with debian:)

# /usr/src/linux$ make-kpkg --initrd --revision 0.1 kernel_image
# /usr/src$ dpkg -i archive.deb

reboot your system.

The ondemand (available since 2.6.10) and conservative (since 2.6.12) are governors
based on in kernel implementations of CPU scaling algorithms: they scale the CPU frequencies
according to the needs (like does the userspace frequency scaling daemons, but in kernel).
They differs in the way they scale up and down. The ondemand governor switches to the
highest frequency immediately when there is load, while the conservative governor increases
frequency step by step. Likewise they behave the other way round for stepping down frequency
when the CPU is idle. The conservative governor is good for battery powered environments on
AMD64 (but may not work on older ThinkPads like the T21). Ondemand may not work on older
laptops without Enhanced SpeedStep due to latency reasons. Anyway, for recent enough Intel
CPU, ondemand is the one recommended for power efficiency (over userspace, and even over
"powersave") by the Intel's kernel developer Arjan van de Ven

the files in /sys/devices/system/cpu/cpu0/cpufreq/ provide information and a means of controlling the frequency scaling subsystem:

your max speed is at /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq:

# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
    1733000

your min speed is at /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq.

# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
    800000

if you are using the userspace governor, you can write to /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed to change the current speed:

# echo 700000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
# cat /proc/cpuinfo
 cpu MHz  : 697.252
# echo 900000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
# cat /proc/cpuinfo
 cpu MHz  : 976.152

you can get a list of available governors with:

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
  conservative ondemand powersave userspace performance

you can get a list of available frequencies with:

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
  1733000 1333000 1067000 800000

current governor?

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
  userspace

the following italic letters are out-dated. the new handling method for cpu frequency scaling after that!

# echo conservative > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

# /usr/src/linux$ make-kpkg --initrd --revision 0.1 kernel_image

wpa

first be sure you have the newest ipw2200 (http://ipw2200.sourceforge.net) and ieee80211 (http://ieee80211.sourceforge.net drivers.

create the file /etc/modprobe.d/ipw2200
insert ‘options ipw2200 hwcrypto=0′

# update-modules

install the package “wpasupplicant”:

# apt-get install wpasupplicant

use the tool wpa_passphrase [passphrase] to generate the crypted psk (pre shared key).
the wpa_suplicant configfile /etc/wpa_supplicant.conf should look a little bit like this:

ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
ap_scan=1
ctrl_interface_group=0
fast_reauth=1
network={
ssid="whateveryouwant"
priority=5
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk=bulb
}

adjust the file /etc/default/wpasupplicant
note the wpasupplicant driver wext. if you want to use wpa, don’t set the ipw driver.

# /etc/default/wpasupplicant
ENABLED=1
OPTIONS="-w -D wext -i eth1 -c /etc/wpa_supplicant.conf"

xorg

my xorg.conf: xorg.conf

xorg works out of the box. use the i810 driver.

because BIOS don’t support the 1400×1050, install “915resolution” and run

# 915resolution -l

choose a resolution you want. edit the file /etc/default/915resolution and apply the values:

MODE=3c
XRESO=1400
YRESO=1050

your xorg.conf should look like this:

kernel: ftp://ftp.eu.kernel.org/pub/linux/kernel/

untar kernel archive and start kernel config:

# /usr/src$ tar xvjf linux-2.6.y.x.tar.bz2
# /usr/src$ ln -s linux-2.6.y.x linux
# /usr/src$ cd linux
# /usr/src/linux$ make menuconfig
# /usr/src/linux$ make oldconfig # when copy old .config file to /usr/src/linux

get system information:

# lspci
