4. Look for the specific device in the FSx section. In our example, the entry is highlighted in Figure 4-4 on page 98. The entry will include the string USB. If the USB device is attached to a USB hub (for example, a memory key plugged into the USB port of a USB keyboard), then two USB strings will appear in the entry, as shown in Figure 4-5.

Access the device by its name followed by the colon; for example, fs2:. 6. Use the commands cd, ls (or dir), cp (or copy), mv, rm to manipulate the files on the device in the same way you would access a device through the operating system. The commands have a similar syntax to DOS or UNIX. However, where there are duplications only one is listed in Help. For example, only ls is listed in Help, but dir also works. If dir /? is typed the syntax for ls is shown. CD-ROM media supported in the x455 can either be ISO9660 (El-Torito) or Joliet format. This differs from the x455 that only supported ISO9660. Writing to the DVD/CD-RW drive is not supported from the EFI shell. If Joliet format is used then we recommend that you use 8.3 DOS format for file names, as the EFI will truncate long file names that may then be difficult to decipher. If ISO9660 (El-Torito) is used then EFI displays the full file name. There are a variety of built-in shell commands. Of note are: help -b displays a list of the available commands. The -b parameter pauses the display after each screen full of information and can be used by many EFI commands. To view the contents of a text file, use the viewer command. To edit any text file, use the edit command. Chapter 4. Installation 99
