<div>==Downloading a working 256 MB disk image from svn==<br />
The current stable disk image with Player 2.0.3, steelebot drivers, and glibc 2.3.1 can be checked out of svn at:<br />
* ssh://gc.caltech.edu/dgc/subversion/mvwt/trunk/users/koishi/steelebot-software<br />
To install this image, follow steps 1-3 and 6 of "Copying a Flash card", substituting the downloaded disk image for <code>steelebot-flash.dd</code> in step 6.<br />
<br />
==Copying a Flash card==<br />
We need to use Rome (192.168.0.10) on the south wall of the lab or any other computer with an attached IDE to Flash interface.<br />
<br />
1. Mount the old flash drive on Rome.<br />
* Shut down Rome by typind <code>sudo halt</code> - make sure the power light is off<br />
* Take a working flash drive and insert it into the IDE to flash interface<br />
* Turn Rome back on<br />
<br />
2. (optional) Check to make sure file system is OK<br />
* <code>sudo mount /dev/hdd1 /mnt/flash</code><br />
** if it works, it should just return without any output<br />
* <code>cd /mnt/flash</code><br />
** type "ls" and you should get a regular Linux file system<br />
<br />
3. Make a copy of the exact contents of the disk<br />
* <code>sudo umount /mnt/flash/</code><br />
* <code>sudo dd if=/dev/hdd of=/tmp/steelebot-flash.dd</code><br />
** Running the <code>dd</code> operation should take 2-3 minutes<br />
<br />
In <code>/tmp/</code> we now have a file <code>steelebot-flash.dd</code> that we will copy to the new flash card.<br />
<br />
4. Shut Rome back down using <code>sudo halt</code>. Insert the new flash card into the interface, then turn Rome back on.<br />
If the disk is already formatted, skip the following step.<br />
<br />
5. ''the step that must be skipped''<br />
<br />
6. Copy the flash image back to the hard disk.<br />
* <code>sudo dd if=/tmp/steelebot-flash.dd of=/dev/hdd</code><br />
** It should take about 5-7 minutes to write to the disk<br />
* <code>sudo halt</code><br />
* Remove the new flash drive from the disk<br />
<br />
Note: this didn't work using flash card 192.168.1.155, but did work on 192.168.1.151. A corrupt sector is suspected.<br />
<br />
==Changing the IP Address==<br />
After successfully copying a flash card, we need to change the IP address so that we don't have any network conflicts.<br />
<br />
The IP address can be found in the following two files on the card:<br />
* /etc/rc.d/rc.inet1<br />
* /etc/hosts<br />
<br />
Change the IP address in both of these files using a text editor. If using vim, you'd open the files using the command <code>sudo vi rc.inet1</code> and <code>sudo vi hosts</code>.<br />
<br />
Note: Richard's old instructions are accessible using the document history.<br />
