[mythtv-users] WOL server using gpxe

[Bill]

I've come up with modifications to gpxe (etherboot) to use it to WOL my 
mythtv server before the frontend boots.  I install gpxe with WOL on a USB 
key, the frontend first boots the USB key, sends the WOL packet to the 
mythtv server, then boots as normal as a mythtv frontend.  This advance 
transmission of the WOL packet gives the backend more time to boot before 
the frontend tries to connect.  This gives a jump of 10-20 seconds compared 
to using a script from init.d to wake the backend.

If anyone is interested I post the code to this mailing list (if its ok to 
send about 5kbytes in files as attachments).  I've only tested the code with 
the e1000 driver, but it is generic and should work with other drivers. 
Note that gxpe has a limited set of ethernet drivers, and you may want to 
check if your ethernet chip is supported first.  If your using the e1000 
driver, there are a few bugs when using it with a 82573 (and likely with 
many other intel chips) that I have posted a fix to the etherboot mailing 
list, but can also send that to those in need.
