AFAIK, Advanced License will get you support for graphical/VESA/VGA modes, and provide virtual media. The standard iLO2 shipped with existing ProLiants should give you full VGA console (80x25) access, power-cycle capability, yadda yadda. Do you really need video support?

Okay, I understand. iLO2 provides serial-over-Ethernet, if I remember correctly. I forget how this works from a networking standpoint (if it's a TCP port you connect to, or if it's some custom protocol), but safe to say someone out there knows. :-) >> I do not trust IPMI based on stories I have heard from Yahoo!

I'm hearing you on FM! :-) You're the 4th or 5th person I've seen who has reported the exact same behaviour with Supermicro's IPMI cards. It makes me VERY glad that I did not shell out the extra cash for the IPMI add-on modules for our Supermicro boxes in our rack. IPMI is one of those things that's presented as a great idea (and it but the actual implementations done by vendors (or at least Supermicro) appears to be a complete mess. Very disappointing. Anyways, once you figure out the iLO2 stuff, be sure to send a mail describing how its working out for you. I've been very curious about it myself, since the last time I saw a ProLiant box, it was one which had an iLO add-on module (e.g. not integrated), and it was first-gen iLO. It was still VERY impressive, but I'm curious to know how things have matured. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
