3157873SimpThis image is intended to be programmed into boot EEPROM.  The image is nearly
4157873Simp0x4000 so it will not fit in KB9200's 0x2000.  It is intended for KB9201 or
5157873Simplater.  Alternatively, the KB9200 can be upgraded with larger EEPROM.
6157873SimpIt performs basic functions prior to executing an image at a
7157873Simpspecified address.  The pre-boot functions can be modified and saved back into
8157873SimpEEPROM.
9157873SimpThe MAC address is set with 0.0.0.0.0.0 by default.  This is an invalid address
10157873Simpand must be changed to a valid value in order to use the ethernet interface.
