Using a USB Flash Device as External Media

Assuming the USB device is /dev/sda you can mount your USB device using the following
command:
mount –t msdos /dev/sda /mnt

Using Network Boot

The following sections show you how to set up and use a network boot environment

Setting Up a Linux Network Boot Server

This section contains instructions for performing a Linux boot over a network.
NOTE:
File locations and process names in this section might vary slightly depending on your
Linux distribution.

Setting Up a DHCP Server

To set up a DHCP server, create and edit a dhcpd.conf file in the /etc directory of your server.
The following is an example assigning a fixed address in a dhcpd.conf file:
allow booting;
allow bootp;
ddns-update-style ad-hoc;
NOTE:
In the following, insert the your DHCP directives, IP ranges, subnet masks, and so on.
group {
next-server IP_ADDRESS_OF_TFTP_SERVER;
filename "bootia64.efi";
host hostname {
fixed-address IP;
hardware ethernetMAC
}
...
}
The next-server command tells the DHCP client where to send the TFTP get request. The
filename command tells the DHCP client which file to get. In this example, the file is
bootia64.efi. When you have finished editing the dhcpd.conf file, restart the dhcpd process,
by entering the following command:
/etc/init.d/dhcpd restart

Setting Up a TFTP Server

Most Linux installations include a TFTP server and an automated method of launching the server
upon receiving a TFTP request. The parent process for detecting a TFTP request and launching
the TFTP server is called xinetd. However, you might have to enable the TFTP service. The
TFTP file is located in the /etc/xinetd.d/ directory. The following is a sample TFTP file:
# default: off
# description: The tftp server serves files using the \
# trivial file transfer protocol. The tftp protocol is \
# often used to boot diskless workstations, download \
# configuration files to network-aware printers and to \
# start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
