Updating firmware from the live host: possible?

[Borley]

I'm still trying to wrap my head around the 1.00 > 2.00 firmware update procedure.

It looks like the files need to be sent from another computer. Can this be done simply by wiring ethernet ports 0 or 1 directly to the BMC ethernet port?

I would rather avoid having to trust another computer in the process, if at all possible.

I guess you could loop it back with the Ethernet ports, but I think a less technically disgusting way would be a USB serial port connected to the BMC headers on the board, and upload things via serial.

Some reading up would have clarified this:

Note that you cannot access the BMC in any way from the host system over network -- the NCSI interface has no support for this, and all access including pings will fail.

Anyway, I have gotten it upgraded a few months ago, the proper way.
