First, let me clarify some requirements.
- You need another computer and add a hard drive that is big enough to hold the image.
(generally the image is 75% to 50% the size of all your data. 20 GB is 10 GB to 15 GB.)
- For maximum speed, all computers should be placed in 1 room at least temporarily. I got a cheap gigabit 24-port Netgear switch.
- A DHCP server can not cross subnets, and if your company has an existing DHCP server it will interfere with it.
- This process generates a flood of multicasts so it is best to do it off the production network.
- If you do this off your production network, you won't have to worry about IT yelling at you for making the network slow.
Basic steps overview:
- Boot another PC (the server) with an added hard drive from the DRBL live CD.
- Connect (server) to the master (unit to be cloned) computer.
- Set it up (see below).
- Network boot (master) and wait for imaging to complete.
- Using "dcs" change the server to "restore disk" mode (See "now its time for the magic" below)
- Network the clients and wait.
- Burn the drbl LiveCD.
- Boot from the LiveCD.
- double click the "Start Drbl"
When it asks for an IP address, I like to use 192.168.0.1.
Accept all the other defaults.
Pre-format the hard drive to hold your image with whatever file system you want.
Open a terminal window and type:
mount /dev/sdb1 /home/partimag
You will now get a GUI.
Enter the name "Now in server"
name the image. (for example:Room 200 )
"use the image partition table"
"turn computer off when done"
Otherwise, accept the defaults.
When it is done, plug the network cable from this PC into the good/master unit. Power it ON and press F12. If network boot is turned on in the BIOS, the computer will boot and the drbl unit will capture it.
Now it is time for the magic:
select the image
Wait for 32 PCs or whatever you have.
When you finish the server will wait patiently for you to network boot all the PCs. As soon as the last PC is fully booted, all computers will image all at once.
