===Bluetooth===
 
 
 
Works out of the box (don't forget to turn it on using the bluetooth button). See [[Bluetooth]].
 
 
 
==Not Losing Android==
 
 
 
===Quick Review===
 
 
 
Not losing Android, as far as I understand, requires some effort on your part. Here is the gist: do '''NOT''' install the bootloader to the MBR but to the partition where you installed Arch.
 
 
 
'''Caution:''' '''You always risk losing data when you are moving or resizing a partition. Don't start the procedure if you do not have a back up, are not sure whether e-recovery (alt+f10 while booting) may work (I do not know if this model has it), do not have recovery CDs ($20 from Acer, does not come with the netbook), or just do not want to risk it.'''
 
 
 
===Details===
 
 
 
When you first turn on your AOD-250 (d250 with android), you will see that it has three partitions:
 
* /dev/sda1 -> "Compaq Diagnostic" (ie System Recovery partition)
 
* /dev/sda2 -> NTFS (Windows XP)
 
* /dev/sda3 -> FAT32 (Android)
 
 
 
I am not quite sure how, but the boot process is initially handled by Acer's tools, not Windows XP's bootloader (NTLDR). In fact, ubuntu's Gparted version identifies this tool as a hidden Windows Vista bootloader. Acer's tool first looks at whether you want (set up) Android to start. If you did, it starts Android up. If you chose Xindows XP, it tells NTLDR to load Windows XP up. So, as far as I understand, if you install another bootloader to the MBR, you lose Android (I did not try it though -I didn't want to take the risk).
 
 
 
So here is what I did:
 
 
 
1. Boot using Ubuntu LiveCD USB (because it had an up to date gparted at time of this writing) to:
 
* shrink Windows' partition to 20G
 
* move /dev/sda3 right after /dev/sda2, so that when I create new partitions, the partition number (sda3) will not change.
 
* create new partitions for Arch installation
 
 
 
2. Install Arch as usual, but tell it to install bootloader to the partition where Arch was installed. In other words, if you install Arch to /dev/sda6, choose /dev/sda6 as the place to install grub when it asks you.
 
 
 
3. Boot with Ubuntu LiveCD USB again to copy the bootloader to a usb disk. If you installed Arch to /dev/sda6:
 
  dd if=/dev/sda6 of=/path/to/usb/drive/arch.mbr bs=512 count=1
 
The name of the file should have less than 7 characters, follow DOS file name limitations (keep it simple).
 
 
 
4. Restart: Windows XP will boot. Copy arch.mbr to C:\ (root of Windows).
 
 
 
5. Edit Windows' bootloader to add Arch to NTLDR's list of operating systems that can be booted up. Open up Windows' terminal window and
 
  cd \
 
  attrib -s -h -r BOOT.INI
 
  notepad BOOT.INI
 
and add a line at the end of that file, like this:
 
  c:\arch.mbr="Arch Linux"
 
and finish the edit by saving the file and fixing its attributes '''again'''
 
  attrib +s +h +r BOOT.INI
 
 
 
6. Have Arch be the default OS to boot for NTLDR: use '''msconfig''' to set the default entry (find the BOOT.INI tab, click on the line that says, for example, ''c:\arch.mbr="Arch Linux"'', and click on "Set as Default". You may also want to change the time out value for NTLDR, see http://vlaurie.com/computers2/Articles/bootini.htm which has nice screenshots on various things to do with the bootloader.
 
 
 
==CPUFREQ and Wrong CPU Freq Reporting==
 
 
 
When you load acpi-cpufreq to do cpu frequency scaling, the maximum CPU speed becomes 1.33GHz instead of 1.66Ghz. There is no workaround for this at time of writing except not using said module, which is not helpful in terms of saving power (battery life for the session). See https://bugs.launchpad.net/ubuntu/+source/cpufreqd/+bug/422858
 
 
 
==Mounting Android from Linux as a Loop Device==
 
 
 
'''This section requires someone to elaborate on what really is happening here.'''
 
 
 
Assuming that Android is in your /dev/sda3 partition and that you have an fstab entry that mounts Androids partition as a vfat filesystem to a folder called /android, I '''think''' you mount Android as a loopback device when you do:
 
 
 
    $ mkdir ~/android-loop #you only need to do this once
 
    # mount /android
 
    # mount -t loop /android/firefox.img ~/android-loop
