I have also used the below procedure when upgrading AW51As to AW51Bs for Y2K. You can set the HostID and Ethernet Address (MAC) to match the old box relatively easily. You really want to keep the same MAC address as before or you will have problems with your CPs booting. I believe (Alex - please smack me if this is wrong) that the CPs are looking for a MAC address for their boot host, and blast out a "Feed Me Seymour" message to what it thinks is the proper MAC address on bootup. There is also a way to work around this if needed, but it is a lot easier to just maintain the same MAC address if you are doing this online.

I have used the procedure outlined in the following link to make a new chip for my AW51B so that I did not have to re-license my applications. http://www.squirrel.com/squirrel/sun-nvram-hostid.faq.html=20 Jim Kahlden jim.kahlden@xxxxxxxx=20 Lower Colorado River Authority Fayette Power Project 6549 Power Plant Road La Grange, TX 78945 (979) 249-8514 (Ph) (979) 249-8390 (Fax) >>> rburnham@xxxxxxxxxxxxxx 1/14/2005 6:57:12 AM >>> Thanks to whom ever sent me info on Sun FAQ's, It was stated that Sun can reconstruct a new NVRAM with the original HostID and Ethernet address. Is this true? And would it eliminate the issues involved with CP hosting, eeprom levels, etc?
