Features

FreeBSD is an UNIX operating system for x86 and others compatible architectures. It is derived from BSD, the version of UNIX® developed at the University of California, Berkeley. It is developed and maintained by a team of individuals.

FreeBSD offers advanced networking, performance, security and compatibility features which are still missing in some of the best commercial operating systems.

FreeBSD makes an ideal Internet or Intranet server. It provides robust network services under the heaviest loads and uses memory efficiently to maintain good response times for thousands of simultaneous user processes. But on notebooks it is a very usable and a great operating system with many features for power management.

With over 17,000 ported libraries and applications for desktop, server, appliance, and embedded environments. There are many applications which were designed for the use with notebooks.

The best is that FreeBSD is free. On the one side the licence model guaranties that (BSD or BSDL licence) and on the other hand it costs nothing. It is certainly possible to buy CDs or DVDs.

Installation

The best way to install FreeBSD on a ThinkPad T43 is to download the ISO files and burn them. You can find the ISOs right here: FTP Server of FreeBSD. Choose the version you want to install.

Hint:
It is better to choose one of the mirrors which you can find here: List of mirrors

Known Issues

Everythings works like a charme except one thing: Suspend und Resume.

ATTENTION!
Currently suspend and resume works only once. I don't know whether it depends on the operation system or on Gnome powermanagement. Entering # acpiconf -s 3 works perfect.

Post-Installation Setup

After installation of FreeBSD you have to do some additional setup. Most things work out of the box, but some parts need additional configuration.

First of all type dmesg on a console and you will see which hardware is detected from GENERIC kernel: 

# dmesg | more

You get an output like the following:

General System Settings

The general system settings are done in my case in the following files:

/boot/loader.conf
In this file you enter modules and settings which must be loaded or set before the kernel is loaded.
/boot/device.hints
Here you can modify device settings and turn on or off devices
/etc/rc.conf
This file is called by the FreeBSD init subsystem. All daemons which should be started and additional settings for these daemons are done done in this file
/etc/sysctl.conf
In this file all settings are done which manipulate deverse kernel parameters
/etc/devd.conf
This file configurates the behavior of the devd device state change daemon
ATTENTION!
The following sections describe how I was able to get everything to work. These are only hints. I am not responsible for any damages which were caused through these settings. You are responsible for yourself what you are doing!

The following sections describe the parameters for each component.

ACPI

This section is the most difficult part of the description.

ACPI stands for Advanced Configuration and Power Interface which defines common interfaces for hardware recognition, motherboard and device configuration and power management. FreeBSD and ACPI is difficult relationship: either it works or it works not. But it is on the way getting better.

It costs a lot of time to get ACPI to work. Therefore a small hint if you want to do it on your own: When you are doing some configuration and testing on your ACPI settings then you will soon recognize that the notebook will be inaccessable and have to press the Power button. The system does not have any chance to shutdown the filesystem and this will result that at every boot the filesystem must be checked and corrected. Therefore it is a good idea to manipulate the mount table /etc/fstab like the following example: 

# Device	Mountpoint	FStype	Options		Dump	Pass#
/dev/ad0s1b	none		swap	sw		0	0
/dev/ad0s1a	/		ufs	rw		1	1
# /dev/ad0s1g	/home		ufs	rw		2	2
/dev/ad0s1d	/tmp		ufs	ro		2	2
/dev/ad0s1f	/usr		ufs	ro		2	2
/dev/ad0s1e	/var		ufs	ro		2	2
# /dev/acd0	/cdrom		cd9660	ro,noauto	0	0
proc		/proc		procfs	rw		0	0
linprocfs	/compat/linux/proc	linprocfs	rw	0	0

The readonly option for the mount command prevents the corruption of the filesystem. If there are important files on your home partition then it is better not to mount it. When everthing works for your satifaction then you can restore the old state of the mount table.

To make ACPI work under FreeBSD the following files have to be edited:

/boot/loader.conf
Add the following line for loading the module acpi_ibm.mo to enable the Thinkpad specific functions like Thinkpad keys:
acpi_ibm_load="YES"
This module can also be loaded directly from the console. For this use the command
# kldload acpi_ibm
/boot/device.hints
Search for the lines which sets the parameters for the mouse driver. They look like these:
hint.psm.0.at="atkbdc"
hint.psm.0.irq="12"
Add or change the flags to this value:
hint.psm.0.flags="0x2000"
This enables the mouse daemon after resume.
/etc/sysctl.conf
In this file the diverse ACPI states have to connected to several events:
hw.acpi.reset_video=1
hw.acpi.lid_switch_state=S3
hw.acpi.sleep_button_state=S3
hw.acpi.power_button_state=S5
hw.acpi.sleep_delay=3
hw.acpi.verbose=1
You also have to enable the Thinkpad buttons with
dev.acpi_ibm.0.events=1
When the notebook resumes after a suspend call it is very likely that the display shows nothing or only rubbish. The reason is that the video controller is not in an defined state. It does not know whether it should display the textmode or the graphics mode. Therefore the switching to the textmode must be enabled:
hw.syscons.sc_no_suspend_vtswitch=0
This values can also be changed directly from the console. For this use the command
# sysctl <mib>
where mib represents each line of /etc/sysctl.conf.
/etc/devd.conf
With device change state daemon it is possible to react on changes in the device state. This can be used for calling the suspend mode. For this the following lines have to be added to the configuration file:
notify 10 {
	match "system" "ACPI";
	match "subsystem" "IBM";
	match "notify" "0x04";
	action "/usr/sbin/acpiconf -s 3";
};
After this the devd daemon has to be restarted:
# /etc/rc.d/devd restart

After changing all these files or values you can do some tests. Hopefully these tests are successful.

CPU controlling

Video

On my Thinkpad I use the following XOrg version:

  • X.Org Version 7.3
  • X.Org X Server 1.4.0
  • Release Date: 5 September 2007

Setting up XOrg is very easy and can be done in a few minutes. For this enter on the console # X -configure This will create a configuration file based on the hardware Xorg has found. This file should be copied to /etc/X11/xorg.conf after the changes were made.

ATTENTION!
It is very important to disable DRI (direct rendering interface) because DRI is responsible for system crashes when calling suspend or resume. Therefore the line Option "DRI" "FALSE" in the section Section "Device", Identifier "T43Card" is highly recommended!

Here is my working XOrg configuration:

Network

The configuration of the LAN device Broadcom Ethernet Controller BCM5750 (bge0) is very easy and it is in a few minutes done.

Network with DHCP
In this case in the system wide configuration file /etc/rc.conf only these entries have to be inserted:
hostname="t43.domain.tld"
ifconfig_bge0="DHCP"
That's it
Network without DHCP
Here you have to insert in the file /etc/rc.conf the IP address of the notebook, the fully qualified hostname and the default router:
hostname="t43.domain.tld"
defaultrouter="<IP address of the router>"
ifconfig_bge0="<IP address of the notebook>"

If the notebook is used in an network with wireless LAN the following lines describe how to do a setup of the WLAN card.

TODO
The setup around the Atheros card (ath0) can be done, when my new WLAN is configured

Bluetooth

Bluetooth works under FreeBSD well. It depends on which devices you use. Generally one line has to be added to /boot/loader.conf: 

ng_ubt_load="YES"

This enables the Bluetooth stack for other drivers and daemon processes.

In my case I use an Siemens S55 mobile phone. Therefore the following three lines enabling a communication with the mobile: 

hcsecd_enable="YES"
sdpd_enable="YES"
bluetooth_enable="YES"

In the subsection Thinkpad buttons of the section Tips and Tricks you can see how to enable and disable the Bluetooth device.

Sound

For enabling the sound card only one line in /boot/loader.conf has to be added: 

snd_ich_load="YES"

Now the sound card can do its job.

Gnome Desktop

Applications

Applets

Additional Hardware

In this section some interesting hardware for the ThinkPad T43 is shown. It is tested under FreeBSD and works perfect.

Adaptec SCSI-Card

A few years ago Adaptec has developed a PCCard for connecting SCSI devices to the notebook. It is called Adaptec SlimSCSI 1460D. This PCCard is recognized correctly from FreeBSD and the device driver aic1 is responsible for that piece of hardware. The card can be changed during a session without restarting the whole system.

NOTE!
The Adaptec SlimSCSI 1460 adapter has to be inserted in the lower slot of the two PCCard/PCMCIA slots!

Here a short excerpt of the system logfile /var/log/messages:

It is an interesting option for backup solutions. So it is possible to connect an tape streamer or DVD-RAM drive (e.g. Panasonic LF-D201, 4,7GB single sided, 9,4GB double sided).

Tips and Tricks

In this section some tips and tricks are described.

Thinkpad buttons

In the section about ACPI the key pair Fn + F4 was used to switch to suspend mode. The other interestin key pair is Fn + F5 which enables or disables the buildin Bluetooth device. Instead of writing for each function a separate script it is better to have one script which execute all functions.

To get the script run you must modify the entry in /etc/devd.conf: 

notify 10 {
	match "system" "ACPI";
	match "subsystem" "IBM";
	action "/usr/sbin/acpi_keys.sh $notify ibm";
};

Here is the (extendable) script with the name /usr/sbin/acpi_keys.sh: 

#!/bin/sh
#

# Check if all parameters are set
if [ "$1" = "" -o "$2" = "" ]
then
	echo "usage: $0 notify oem_name"
	exit 1
fi

# storing the parameters in variables
NOTIFY=`echo $1`
OEM=$2

# for easier modification set some variables to system commands
LOGGER="/usr/bin/logger"
SYSCTL="/sbin/sysctl"
ACPICONF="/usr/sbin/acpiconf"

# start scripts for bluetooth
# important: set all to "YES" in /etc/rc.conf!

# hcsecd_enable="YES"
HCSECD_ENABLE="/etc/rc.d/hcsecd start"
HCSECD_DISABLE="/etc/rc.d/hcsecd stop"

# sdpd_enable="YES"
SDPD_ENABLE="/etc/rc.d/sdpd start"
SDPD_DISABLE="/etc/rc.d/sdpd stop"

# bluetooth_enable="YES"
BT_ENABLE="/etc/rc.d/bluetooth start ubt0"
BT_DISABLE="/etc/rc.d/bluetooth stop ubt0"

# check which key was pressed
case ${NOTIFY} in
	0x04)
		# suspend/resume key Fn + F4
		MESSAGE="ACPI mode S3 activated"
		${ACPICONF} -s 3
		;;
	0x05)
		# bluetooth on/off key Fn + F5
		LEVEL=`sysctl -n dev.acpi_${OEM}.0.bluetooth`
		if [ "$LEVEL" = "1" ]
		then
			${MOBILE_DISABLE}
			${HCSECD_DISABLE}
			${SDPD_DISABLE}
			${BT_DISABLE}
			${SYSCTL} dev.acpi_${OEM}.0.bluetooth=0
			MESSAGE="bluetooth disabled"
		else
			${SYSCTL} dev.acpi_${OEM}.0.bluetooth=1
			MESSAGE="bluetooth enabled"
			sleep 2
			${HCSECD_ENABLE}
			${SDPD_ENABLE}
			${BT_DISABLE} # reinitialize BT stack
			${BT_ENABLE}
		fi
		;;
	*)
		;;
esac

# log all activities to syslog (/var/log/messages)
${LOGGER} ${MESSAGE}

exit 0
