[eepro100] Sleep Mode Enabled

I am using the latest driver with an intel PRO/100+ PCI card.  I got 
the following message at startup...  

  eepro100.c:v1.24 7/25/2002 Donald Becker <becker@scyld.com>
  eth0: Intel i82559 rev 8 at 0xc4814000, 00:D0:B7:BE:FE:A8, IRQ 10.
    Board assembly 721383-009, Physical connectors present: RJ45
    Primary interface chip i82555 PHY #1.

    ** The configuration EEPROM enables Sleep Mode.
    ** This will cause PCI bus errors!
    ** Update the configuration EEPROM with the eepro100-diag program.
    General self-test: passed.
    Serial sub-system self-test: passed.
    Internal registers self-test: passed.
    ROM checksum self-test: passed (0x04f4518b).

I researched the 82559 datasheet and found that this (I beleive) is 
refering to the EEPROM address 10h bit 1 (Standby Enable).  But the 
data sheet is not too clear as to how this state occurs.  Does 
anyone know what events (or lack thereof) cause the 82559 to enter 
the standby state?  And how do the PCI bus errors manifest 
themselves?  I.E.  What kind of error messages would I see if this 
was occuring?
