Simple Things Which Work Now

Talk to MCH Console

(Windows) Connect to bul3x1 with remote desktop (log in as daq). Launch putty.exe from desktop. Click on 'USB for MCH COM4' and 'Open'. If this gives an error, try again with 'USB for MCH COM3'. Then hit "Enter" and you should get the "nat>" prompt, and you can type commands.

To read/write registers on the CLK board:

  nat> diag
  [0] : no action
    .....
  DIAG (REG=0/0x0): 9

This will take you to the clock menu. Options 2 and 3 read and write registers. For the "Choose clock device" question answer 0.

To check versions, just type

  nat> version

Standards, Documentation

• NAT-MCH Users Manual (v117) – see communication section starting on p. 41
• ASF Specification which includes RMCP (used to send IPMI messages over ethernet)
• IPMI Specification Intelligent Platform Management Interface, see Wikipedia
• [http://www.openhpi.org/][OpenHPI] might also be useful (mentioned in the NAT-MCH manual) but I'm not sure yet how it fits into the puzzle
