The "error" message is merely informational.  The on-board aic7xxx chips do
not have a serial EEPROM; they have non-volatile RAM in which the BIOS settings
are stored.  The driver knows how to read a serial EEPROM but not NVRAM (and
fails the checksum test in reading the serial EEPROM) so it just uses BIOS
settings leftover in scratch RAM on the card.
