This is a very lame page about the first Compaq RiLOe  (Remote Inside Lights Out Edition) card, the first version i.e. i960/66Mhz & Ati Rage IIC… because you can get it for cheap it can be considered a poor-mans IPMI.
I had the page hanging around on my server for years and moved it here for completeness. As it is getting vintage by now, it actually fits Under construction. Forever.
There are better pages out there, so I only provide additional info/stuff.

Software

You can get the manual here

The most recent (and last) firmware 2.53, which also resets (unknown) passwords is available here – NB: This is a MSDOS instsaller and needs two 1.44MB floppies.

Here’s an RPM, which writes the SNMP packets of the RILOE into the syslog.  Here’s the README.

Hardware

I went the extra mile and created a pinout (also available as PDF here). It’s not tested though.

The power supply looks like this:

10 volts, Plus inside, minus outside of the plug.
