I had wondered about an snmp administration method. Hopefully,
someone's got some literature about it so I can do the fix from my
Debian workstation, should I need to. I'm all out of floppies to make
DOS boot disks :(.
The weird thing is, after moving all the machines in question onto a new
shelf, none of the machines which previously listened for wake-on-lan
don't do it anymore. Settings must be stored on an EEPROM which is not
powered by the BIOS battery.
