 +==== IBM 39Y6070 ====
 +The IBM 39Y6070 is a NIC with a BCM5708C chip.
 +The picture below includes two headers I soldered in.
 +In the top-left corner of the NIC (J334), we can access the Debug UART as shown here (again note that it doesn't come with this header):
 +I used a TTL to RS232 cable ([[http://www.superdroidrobots.com/shop/item.aspx?itemid=337|here]]). The settings are 192008N1, the prompt is ">" (see [[gsoc/bnx2#References|[1]]] for more info).
 +There are 3 documented commands:
 +^ Syntax      ^ Example       ^ Description          ^
 +| r<addr>    | r145000     | Read a 32-bit register value from address <addr>        |
 +| d<addr>    | d145000     | Dump 256 32-bit registers, starting at <addr> |
 +| w<addr> <data>    | w145000 ff     | Write <data> to the 32-bit register at <addr> |
 +The best source for the register addresses is bnx2.h from the bnx2 linux driver, available
