[kwlug-disc] Supermicro board

[unsolicited]

Third it.

Particularly when it's sitting at the BIOS, having thrown up a hardware 
error message. Maybe you still have to drive, but maybe you can bring 
some spare parts with you on the FIRST trip! Or, if you get lucky, it's 
only 'Press F1 to continue.', and you can. (Mind you, something changed 
for that to come up - which you probably want to look in to.)

For access it's probably good practice to limit things to the local 
subnet. One probably has remote access in some form to somewhere on that 
- connect there then hop over to the console. You'll likely only be 
dealing with text screens, and for a short time. (If the machine comes 
back up at all you'll have reestablished ssh or whatever access, and 
you'll want to continue via your normal tools, not this facility.)

- even getting someone to vnc invite you to something on that subnet is 
preferable to a drive only to have press F1.

Relative to native remote screen solutions that are running under the host OS and have knowledge of the internals of what's happening with the graphics, etc, the latency/performance of things like the AST2400 tend to be relatively terrible.  But you don't care about that when it's the difference between being able to save the day from your desk VS having to drive somewhere or talk some random person through a complex series of steps over the phone... :)
