==IO Ports==
In 32bit mode the card has only 4+6 IO ports necessary to use the card:
{| {{wikitable}}
! Offset (from IO base)
! Name
|-
| 0x00 || MAC0-MAC5
|-
| 0x10 || RDP

'''MAC0-MAC5''' are the ports used to access the MAC address stored in the card's ROM. These should be accessed byte-by-byte in order to
ensure compatibility with all three emulators.
'''RAP''' is the Register Access Pointer, and selects which card register one wants to access.
'''RDP''' is the Register Data Pointer and is the port used to access the first set of registers
'''BDP''' is the Bus Configuration Data Port and is used to access the second set of registers
'''RST''' is used to reset the card.
