Ie.. if the battery dies and the system sits long enough, the MAC is lost and has to be re-set with a rather painful procedure.
AFAIK not for the Indigo, because its MAC address is stored in an EEPROM (on the backplane IIC, see e.g. [1]) whereas the Indy stores it in the NVRAM (see e.g. [2]), similar to older machines from Sun. So the MAC address of the Indigo can only be corrupted by (1) changing system boards to the R4K version and back to the R3K version without correcting it with the R3K board or (2) maybe if the EEPROM dies.
