[1] - Needed for Fn + F2 operation to enable/disable wireless. [2] - An experimental driver for the Ralink 2860 chipset is available at the ralink_drivers.git repository. See also this topic at the FreeBSD foums.
Some users found that enabling powerd causes sudden reboots and problems with the SD card and/or external devices.
The problem may lie in acpi_throttle(4). Please don't enable powerd or disable acpi_throttle in your loader.conf on the 701. If you disable acpi_throttle, powerd is useless because the Eee PC 701 CPU has no Enhanced Speedstep support.
Some users found that using the eeemon(4) kernel driver and enabling “high voltage” (sysctl dev.eeemon.0.voltage=1) makes some SD/SDHC cards functional. The error/success on this behavior depends on the card itself.
Another thing to do if you get write errors or your system hangs when writing to the SD/SDHC card is to try changing the BIOS setting of “OS Installation” to “Start”.
The following should change in your dmesg:
da0: 40.000MB/s transfers
to:
da0: 1.000MB/s transfers
This may not make the problem go away entirely, but makes it less problematic.

The easiest way to install FreeBSD on an eee is to use the USB memory stick image. Transfer this to the memory stick with dd:
dd if=FreeBSD-9.0-RELEASE-i386-memstick.img of=/dev/da0 bs=10240 conv=sync
taking extreme care that the device name (/dev/da0 in the example) is correct. The memory stick image is available under /pub/FreeBSD/releases/i386/ISO-IMAGES/8.0/. Alternative, you can build from source.' A detailed procedure is explained at http://bsdimp.blogspot.com/2007/10/building-bootable-freebsdi386-images.html . This builds “Live Pen Drive” version of FreeBSD.
Pressing “Escape” on the BIOS boot screen allows you to select the boot device. After a sucessful boot, install FreeBSD on the SSD by typing (WARNING: this erases your SSD!):
# fdisk -I ad2 # fdisk -B ad2 # bsdlabel -w ad2s1 auto # bsdlabel -B ad2s1 # newfs -U /dev/ad2s1a # mount /dev/ad2s1a /mnt # cp -Rp /COPYRIGHT /.cshrc /.profile /b* /etc /home /l* /sbin /r* /usr /mnt # mkdir /mnt/dev /mnt/tmp # chmod 1777 /mnt/tmp
Add the following to your /etc/fstab:
/dev/ad2s1a / ufs rw,noatime 1 1 tmpfs /tmp tmpfs rw,size=20000000 0 0
This creates a 20Mb tmpfs file system on /tmp.
Don't forget to add this to your /boot/loader.conf:
snd_hda_load="YES" acpi_asus_load="YES" hw.pci.do_power_nodriver=1 kern.hz=100
Basic stuff works. What you need to make it work/caveats:
hw.acpi.reset_video=1 (add it to /etc/sysctl.conf)hw.acpi.sleep_button_state=S3 so that the sleep button actually suspends.sysctl hw.acpi.asus.lcd_brightness=8 to /etc/rc.resume (after the kldunload comment).umount the SD or SDHC card before suspending. The Eee will detach the USB card reader on suspend and reattach it on resume. What doesn't work:
snd_hda(4) has no resume support. You have to kldunload it before suspend and kldload it after resume.ae(4) WOL support was not tested.The ae(4) driver first appeared in FreeBSD 7.1.
This one is second generation of L1 controller which is supposed to be heavily modified by Atheros after acquiring Attansic. It supports the AR8121, AR8113 and AR8114.
The driver first appeared in FreeBSD 7.1.
The driver first appaered in FreeBSD 8.0.
See per-model notes.
Update to latest HEAD or RELENG_7 and make sure you have acpi_asus(4) loaded.
The following should show up on dmesg:
acpi_asus0: <ASUS EeePC> on acpi0
After that, the hotkeys should work out-of-the-box. If you don't like how we configured them in /etc/devd/asus.conf, edit that file and suit it to your preferences.
eeemon(4) is a hardware monitor and tunable for your Eee. With it, you can monitor the temperature and the fan speed. You can also alternate between High/Low voltage and control the fan speed.
Fetch and install http://svn.freebsd.org/viewvc/base/user/rpaulo/eeemon/ .
This module creates dev.cpu.0.temperature and dev.cpu.0.fan (note that this is from a different source than ACPI, but the value is usually the same).
