=====Etherboot command-line=====
====Network Interfaces====
Etherboot names interfaces following the pattern "net#".

**ifstat [interfaces...]** Displays information and statistics about the specified interface.  If no interface is specified, displays information about all detected interfaces.  Information includes MAC address, PCI bus/slot/function identiers, and packet counts.

**ifopen [interfaces...]** Opens the specified interfaces.  If no interface is specified, opens all interfaces.

**ifclose [interfaces...]** Closes the specified interfaces.  If no interface is specified, closes all interfaces.

**dhcp <interface>**  Attempts to configure the specified network interface using DHCP.  Also opens the interface.

====Working with images====
**imgfetch [-n|--name <image name>] <filename> [arguments...]** Retrieves an image file, giving it a specified name, and prepares it to be executed with the specified arguments.  File name may be a simple path, or an HTTP URL.  Simple paths are assumed to be located on the TFTP server specified by dhcp or **config**.  If //image name// is not specified, the base filename will be used as the name.

**module [-n|--name <image name>] <filename> [arguments...]** Equivalent to **imgfetch**

**initrd [-n|--name <image name>] <filename> [arguments]** Fetch and load an initrd.  Equivalent to imgfetch, but it sets the imagetype to initrd.  There is not currently any way to mark an image as initrd once it's been fetched.

**imgargs <image name>**  Set or change the arguments for the specified image name.

**imgload <image name>** Prepares an executable image to be executed.

**imgfree** Remove all fetched/loaded images.

**kernel [-n|--name <image name>] <filename> [arguments]** Fetch and load a bzImage format Linux kernel.  Equivalent to an imgfetch followed by imgload.


====Variables====
This doesn't seem to work, as it always says "file not found"

**set <identifier> <value>** Set the value of //identifier// to //value//

**show <identifier>** Display the value of //identifier//

**clear <identifier>**  Clear the value of //identifier//

====Other====
**autoboot** Attempts to boot the system

**config** Enters a configuration GUI to set up various parameters

**exit** Exits gPXE, and passes boot control back to the BIOS.

**sanboot** Attempts to boot the system from a SAN device.

====Outstanding questions====
  * What does autoboot do?  Does it simply execute a script, pre-defined at compile time?  Does it follow its own sequence of boot operations?
  * When multiple images of the same name are fetched, which one will takes precedence?
  * What does the  **initrd** command do that's special?  It obviously sets the image type to initrd, but what's the effect of that?  Is there a way to specify the type of a loaded image after the fact?
  * What are the **set**/**clear**/**show**
