|  | </div> | 
|  |  | 
|  | <h3>Hardware</h3> | 
|  | <p>This guide covers the creation of a bootable USB drive.  Your | 
|  | computer BIOS must support booting from USB and You will want at least 3GB of | 
|  | RAM.  You also will need a USB drive of at least 2GB.</p> | 
|  |  | 
|  | <h3>Software</h3> | 
|  | <p>Ubuntu 11.10 (Oneiric Ocelot) is required on host to create images.</p> | 
|  | </section> | 
|  |  | 
|  | <section id="installation"> | 
|  | <div class="page-header"> | 
|  | <h2>Installation <small>bit blasting</small></h2> | 
|  | </div> | 
|  |  | 
|  | <h3>Set Up USB Drive</h3> | 
|  | <ul> | 
|  | <li>Insert the USB drive into the computer.  Make a note of the device name, such as | 
|  | <code>sdb</code>. Do not mount the device.</li> | 
|  | <li>Install the boot system: | 
|  | <pre>tools/build_usb_boot.sh /dev/sdb1</pre> | 
|  | <p>This calls tools/build_ramdisk.sh to create a 2GB ramdisk | 
|  | containing a complete development Oneiric OS plus the | 
|  | OpenStack code checkouts.  It then writes a syslinux boot sector | 
|  | to the specified device and creates <code>/syslinux</code>.</p> | 
|  | </li> | 
|  | <li>If desired, you may now mount the device: | 
|  | <pre>mount /dev/sdb1 /mnt/tmp | 
|  | # foo | 
|  | umount /mnt/tmp</pre> | 
|  | </li> | 
|  | </ul> | 
|  |  | 
|  | <p>Now <a href="ramdisk.html">return</a> to the RAM disk Guide to kick | 
|  | off your DevStack experience.</p> |
