The nice thing about IPMI/SOL is that one can 'talk' to the board
via the ethernet without intervention of the local OS, so that, in theory
at least the 'panic message' is also available - there is a BMC that
highjacks UDP packets to port 623.

i say 'in theory' since i have not seen this working, the boards i have,
Intel SE7501WV2 have 2 serial ports, and with some older BIOS i was
able to get both the BIOS console and FreeBSD com to go via com1/cuaa0.

though they are IPMI 1.5, so far i can via the ethernet do basic management
(power off, reset, get logs) but im still trying to figure out the Serial
Over Lan part.

There is a client that runs under windows that should allow connection
via SOL to the console - im still waiting for the intel rep. to show me how,
since i keep getting '.. not supported'.

the Windows client works as a telnet proxy: on a client one types
telnet localhost 623, and then one is promped for host/user/password.

Sorry if all this seems confusing, try to make sence from the IPMI 1.5 Specs :-)
(so far the 2.0 seems more of the same, with some attempt to make all
this more secure - by obscurity.

The upshot off all this is, if the SOL works, then we can kiss KVM away, and
as Robert said, just power and ethernet and you are set.
