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.
