+There exist several manuals on how to install Linpus from a recovery DVD.
+
+Basically you just boot the recovery DVD on some PC, select "*create rescue usb key*" and insert a 2 GiB (or more)
+usb key.
+
+:warning: 1 GiB won't work - the recovery image is slightly larger :warning:
+
+After the recovery stick has been created, you can plug it into the AAO and start the recovery process. This wipes
+the complete harddisk so make sure you have a backup of your important data.

+After playing around a bit, my Aspire One (v3114) got bricked after a normal reboot (blank screen, power led and
+fan on, nothing else). There's a nice recovery procedure for the BIOS at [macles](http://macles.blogspot.com/2008/08/acer-aspire-one-bios-recovery.html).
+
+1. download the latest BIOS from [Acer](http://support.acer-euro.com/drivers/notebook/as_one_150.html)
+1. format an USB stick with FAT32 / VFAT
+1. put the files `FLASHIT.EXE` and `ZG5_`*version*`.fd` onto the stick
+1. rename the ZG5-file to `ZG5IA32.FD`
+1. now connect this stick to your AAO, also connect the battery and the power supply
+1. hold Fn-ESC down while powering on the AAO
+1. release when the Power-LED starts blinking
+1. (maybe press the power button to initiate the process)[^1]
+1. :warning: **DO NOT INTERRUPT THIS PROCESS!!!** :warning:
+1. wait until the blinking ends and the AAO reboots a bit later
+
+
+Somehow an A150L with the v3114 BIOS didn't let me update it to v3304. The Power-LED was blinking and the LED on my
+flash drive flashed but after a few seconds, the A150 rebooted and the BIOS reported still the v3114.
+
+
+[^1]: I'm not sure whether this is neccessary as I don't remember doing it when recovering my bricked A150X

+There's a nice help page at the [Ubuntu page](https://help.ubuntu.com/community/AspireOne).
+
+**Needed:**
+
+* 1+ GiB USB stick
+* Ubuntu 8.04.1 install CD
+* [liveUSB](http://klik.atekon.de/liveusb)
+* a wired network connection
+
+
+**Missing features:**
+
+* Hibernation on the A110
+* Power saving for Card readers and WLAN
+* WLAN switch
+
+
+Intrepid Ibex (8.10)
+====================
+
+Works almost out-of-the-box. You just have to blacklist the `ath_pci` module to make the WLAN card work. Everything
+else seems to work fine. You might have to keep the `setkeycodes` mappings for the popup displays when changing volume
+or brightness to work. The WIFI LED doesn't work with the `ath5k` module but the killswitch does.
+
+
+Blank screen on bootup
+----------------------
+
+If you got a blank screen after *grub*, remove any `vga=0x314` (or similar) parameter from your kernel line. Intrepid
+now uses *uvesafb* which depends on *v86d* (not automatically installed!!) and seems to have some problems finding the
+internal VGA card upon bootup.
+
+A small workaround has been posted at [UbuntuForums](http://ubuntuforums.org/showthread.php?t=938874&highlight=boot+screen):
+
+1. install: *v86d* and you might want *fbset*
+1. create: `/etc/modprobe.d/uvesafb` with the following content:
+
+ options uvesafb mode_option=800x600-16 mtrr=3 scroll=ywrap
+
+1. edit: `/etc/modprobe.d/blacklist-framebuffer` and add:
+
+ blacklist uvesafb
+
+1. edit: `/etc/modules` and add:
+
+ uvesafb
+
+1. run: `update-initramfs -u`
+1. reboot
+
+Jaunty Jackalope (9.04)
+=======================
+
+Works 99% out-of-the-box. Add `acer_wmi` to `/etc/modprobe.d/blacklist` to get the `ath5k` module working. Also you
+might need to install `linux-backport-modules` to make the `lbm_cw_cfg80211` accept the `regdom` option. (If you're
+in Europe, you might want to add the following line to your `/etc/modprobe.d/options`:
+
+ options lbm_cw_cfg80211 ieee80211_regdom=EU
+
+This sets the *regulatory domain* to **EU** which enables channels 12-14 (see [Wikipedia](http://de.wikipedia.org/wiki/Wireless_Local_Area_Network#Frequenzen_und_Kan.C3.A4le)).
+The non-lbm-module doesn't like this option.
+
+
+more tips
+---------
+
+The [ArchLinux Wiki](http://wiki.archlinux.org/index.php/Acer_Aspire_One) contains several tips for tweaking a Linux
+to suit the *Aspire One*. Also take a look at the [[:know-how:software:linux:start]] section on this page.

+**Chipset:** Atheros AR2425
+
+Change Regdomain
+================
+
+The WiFi card comes set to regdom `0x65` (World/ETSI C) which limits the channels to 1..11. (`iw list` shows
+channels 12..14 as *disabled*.) In Germany, there are also channels 12 and 13 which are unusable this way. But
+there's the tool `ath_info` which can read and write the EEPROM on the card and thus also the regdomain.
+
+First, find the base address of the adapter using
+
+ lspci -vv
+
+Mine was at address `75200000`. Now you can dump the contents of the EEPROM using
+
+ ath_info 0x75200000
+
+To write the EEPROM, you have to unlock it by setting a GPIO register, namely the first, to zero. I changed the
+regdomain to 0x00 (=ALL channels available) 0x68 (=EU1 World) using this command:
+
+ ath_info -g 1:0 -w 0x75200000 regdomain 68
+
+You can find all valid codes by looking at the `DMN_` constants in the
+[regdom.h](http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/drivers/net/wireless/ath5k/regdom.h) file.
+
+After unloading the modules: `ath5k`, `ath`, `mac80211` and `cfg80211` and doing a `modprobe ath5k`, the command
+`iw list` should show the two new channels enabled.
+
+
+**For older ieee80211 modules**, there's a module option `ieee80211_regdom` for the `cfg80211` module. This takes
+the values `US`, `JP` or `EU`. Add the following lines to `/etc/modprobe.d/options`:
+
+ options cfg80211 ieee80211_regdom=EU
+ options lbm_cw_cfg80211 ieee80211_regdom=EU
+
+And after a reboot, you will have channels 12 and 13 available.
+
+On Jaunty, you have to install the package `iw` and use the following command in e.g. your `/etc/rc.local` to set
+the regdomain to *Germany*:
+
+ iw reg set DE
+
+
+Possible errors
+---------------
+
+If you get the message `MAC revision 0xffff is not supported!` it means that some other module, likely `ath_hal`
+and/or `ath_pci` took over your card.

+To update the BIOS without Windows, install [UNetBootIn](http://unetbootin.sf.net/) and use it to put FreeDOS on a
+flash drive. Now extract the e.g. `v.3305.zip` to it and reboot the machine. Press F12 in the right
+moment and select your USB flash drive from the list. Press ENTER when you see the `boot:` prompt, then
+launch the *Default* configuration and select to boot FreeDOS without any drivers.
+
+Now you should be at the `A:\>` prompt which is the emulated floppy drive. Change to `C:` and execute `3305.BAT`.
+
+
+Gateway BIOS
+============
+
+[macles](http://macles.blogspot.com/2009/03/brightness-table.html) points out that there are netbooks with the same
+hardware as the AAO and therefore the BIOS file is compatible. You can download the Gateway-BIOS from there. In the
+comments you will find tips and tricks if your sound or function keys are not working after the update.

+**Model:** [JMicron JMB38x](http://www.jmicron.com/Product_JMB38X.htm) PCI Express to 1394a OHCI and Memory Card Host Controller
+
+
+Since *Ubuntu Karmic Koala*, the card reader seems to be recognized fine - but only, **if there is a card inserted upon bootup**.
+
+
+
+Enabling the device
+===================
+
+The cardreader device seems to be hidden on bootup and you have to enable it by issuing:
+
+ setpci -d 197b:2381 AE=47
+
+This didn't work on the commandline but inside the `rc.local`, my 16GiB SDcard in the left slot was recognized fine.
+
+
+Multicard-reader driver
+=======================
+
+The right-hand SD slot is actually a multi-card reader for MMC, SD, xD and MemoryStick. This device doesn't seem to be
+recognized by my Ubuntu.
+
+There's a project called [TI FlashMedia xx12/xx21 driver](http://tifmxx.berlios.de) which also contains the kernel
+modules for the jmb38x. The Linpus Linux on the A150L loads modules with exactly those names: `jmb38x_xd`,
+`flash_bd`, `memstick`, `mspro_block`, `xd_card` and `jmb38x_ms`.
+
+The [UbuntuForums](http://ubuntuforums.org/showpost.php?p=5778068&postcount=70) contain a HowTo for installing the
+TI-part of that driver. I proceeded the same way but installed those modules mentioned above instead of the TI ones.
+Modprobing them on command-line worked fine, but after adding the modprobes to the `rc.local`, the next boot ended up
+in continuous *soft lockups*.
+
+So make sure you keep an USB stick with the [SysRescCD](http://www.sysresccd.org/Sysresccd-manual-en_How_to_install_SystemRescueCd_on_an_USB-stick) handy.
