Documentation of the process of installing archlinux and Windows 7 in a dual-boot configuration.

System Specs

• AMD X2 dual-core processor, running at 2.8 ghz, circa 2002
• ASUS ATX motherboard
• 2 gigs of ram
• 100gb drive
• nvidia gtx 550 ti graphics card
• linksys wmp54g wireless pci network card
• 550w power supply

Installing Windows

Windows was installed from a USB stick using Microsoft's Windows 7 USB/DVD tool. It's required to create this key from a Windows 7 system. Boot with the USB drive, then install Windows on the drive in a single partition. Windows also creates a System Reserved partition for itself. Once installed, via Start Menu > Administrative Tools > Computer Management > Disk Manamagent, select 'Shrink Partition' on the main Windows parition to create another partition for Arch. The default value for the shrink is 50%, so for my setup the value for the new disk size was ~50GB, which was ideal.

Note about this install. I have an old Linksys (Cysco) WMP54G Wireless PCI Card. Drivers from Linksys/Cysco's website didn't work, but following this blog post, the generic RALink drivers worked great.

Working with various interfaces that output json or xml results in lots of situations where you have a single-line, unformatted output. Here's a quick way to format json, xml from the CLI.

via the command line:

format json

cat unformatted.json | python -m json.tool

format json from clipboard

pbpaste | python -m json.tool

format xml from clipboard

pbpaste | xmllint --format -

for all above examples, you can pipe back to the clipboard with | pbcopy at the end of the command, or output to a file with > output.json or > output.xml.

Since there is no equivilent to /dev/dsp or /dev/audio on OSX, you need to install an alternative like sox.

Install sox by either downloading the OSX binary from http://sox.sourceforge.net/
or
install homebrew, and then install sox with brew install sox

Examples

cat audio from /dev/urandom/ :

cat /dev/urandom | sox -traw -r44100 -b16 -u - -tcoreaudio

audio from an executable

cat > test.c
main(t) {
  for( t = 0;;t++)
    putchar( t * ((( t >> 12 ) | (t >> 8)) & (63& (t >> 4 ))));
}

gcc test.c -o test
./test | sox -traw -r8000 -b8 -u - -tcoreaudio

How to install cygwin on windows:

1. Install Cygwin from setup.exe

2. Install the following packages:

   • xorg-server (required, the Cygwin X Server)
   • xinit (required, scripts for starting the X server: xinit, startx, startwin (and a shortcut on the Start Menu to run it), startxdmcp.bat )
   • xorg-docs (optional, man pages)
   • X-start-menu-icons (optional, adds shortcuts to X Clients and Server to the Start menu)
   • mintty (windows-feel terminal)
     
     

3. Optional Packages

   • openssh
   • git, svn
   • wget, curl
   • rsync
   • vim, emacs
   • any additional fonts

   
   

1. diskutil list
   Determines the device node assigned to your flash media (e.g. /dev/disk2)

2. diskutil unmountDisk /dev/disk#
   Replace # with the disk number from the last command; in the previous example, # is 2)

3. sudo dd if=/path/to/example.iso of=/dev/diskN bs=1m
   Replace /path/to/example.iso with the path to the iso; for example: ./windows7.iso. After typing in your sudo password, the process will start invisibly.

4. diskutil eject /dev/disk#
   Remove your flash media device when the command completes. Done!

Bonus tip! You want to see how far the dd copy is coming along? Run in another terminal instance:
$ sudo killall -INFO dd
The process info will display in the original terminal.

copy /b file1+ file2 output

eg

copy /b picture.jpg + archive.rar file.jpg

Open file.jpg with the default application, it will show the picture "picture.jpg". Change the extension to "file.rar" or if you try to open "file.jpg" with an archiver you will get the contents of "archive.rar".
