This will follow the steps involved in setting up Arch Linux on a Compal CL56/CL56P Laptop. This is a very common base laptop system that is rebranded by a lot of different companies. This is specifically going to be about the steps needed for a Velocity Micro B51 Campus Edition working fully. There is a linux-laptop.net page:  for the CL56, as well as another page here:  also for the CL56.
This will follow all the special things I have had to do and anything new that I come across as it happens. Out of the 'box' as it were Arch works decently.

- Wireless (Intel Pro Wireless 2200BG)
- The ipw2200 driver which make it work is included in the kernel but you may have to install the ipw2200 firmware to make it work (pacman -S ipw2200-fw). The card supports managed, ad-hoc and monitor modes.
- The wifi switch needs the acerhk module: its source is available at , but a PKGBUILD is available on the AUR.
- After compiling the module, it needs to be added to the MODULES array in /etc/rc.conf. The AUR build includes a daemon that activates the module, to have it started at boot time add it to the DAEMONS array in /etc/rc.conf.
- SD (Secure Digital) card reader/writer
- It is physically located just underneath the CardBus slot.
- MMC read/write support works with mmc_block driver.
- Add mnt/mmc directory and the following line to /etc/fstab
/dev/mmcblk0p1 /mnt/mmc vfat rw,user,auto,exec,sync 0 0
- After loading the snd_intel8x0 module the card works without problems.
- ATI Radeon
- just follow the ATI wiki
- use X.org and just download the proper driver from ATI homepage
- performance is is about 2100 fps with glxgears and 410 fps with fgl_glxgears if drivers are installed correctly
- VGA Dual Monitor Head Output/S-Video output
- works, just use the configuration application included with ATI drivers
- works with standard kernel, just add the following line to /etc/rc.local
- add irda ircomm ircomm-tty to /etc/rc.conf MODULES list.
- for using GPRS over IR add the following line to /etc/rc.local
mknod /dev/ppp c 108 0
and use pppconfig to configure the connection settings (use /dev/ttyS0 as the port)
- Touchpad and access to few informations like temperature and fan level
- install aur/omnibook-svn (here with kernel 2.6.25-ARCH, the aur/omnibook did not work)
- add omnibook to MODULES in /etc/rc.conf (MODULES=(... omnibook ...))
- add a line with "options omnibook ectype=1" in /etc/modprobe.d/modprobe.conf (if not set, loading omnibook will fail)
- For touchpad configuration see Touchpad_Synaptics (use first configuration, not the one for the ALPS touchpads)
- to get temperature: cat /proc/omnibook/temperature
- to see other options: ls /proc/omnibook/*
