+This board specific command:
+============================
+
+This board has the following its specific command:
+
+ - hwtest
+ - printmac
+ - setmac
+
+
+1. hwtest
+
+This is self-check command. This command has the following options:
+
+ - all		: test all hardware
+ - pld		: output PLD version
+ - led		: turn on LEDs
+ - dipsw	: test DIP switch
+ - sm107	: output SM107 version
+ - net		: check RTL8110 ID
+ - sata		: check SiI3512 ID
+ - net		: output PCI slot device ID
+
+i.e)
+=> hwtest led
+turn on LEDs 3, 5, 7, 9
+turn on LEDs 4, 6, 8, 10
+
+=> hwtest net
+Ethernet OK
+
+
+2. printmac
+
+This command outputs MAC address of this board.
+
+i.e)
+=> printmac
+MAC = 00:00:87:**:**:**
+
+
+3. setmac
+
+This command writes MAC address of this board.
+
+i.e)
+=> setmac 00:00:87:**:**:**
