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.
