Load the EEPROM contents

Print identification message

Retrieve the Hardware address and print it on the screen.

Program the MAC address into the station address registers

Fill in our entry in the etherboot arp table

Read the media options register, print a message and set default xcvr.

Uses Media Option command on B revision, Reset Option on non-B revision cards -- same register address

mask out VCO bit that is defined as 10baseFL bit on B-rev cards

Determine transceiver type to use, depending on value stored in eeprom 0x16

User-defined

I don't know what MII MAC only mode is!!!

enable DC converter for 10-Base-T

Set the link to the type we just determined.

Now that we set the xcvr type, reset the Tx and Rx, re-enable.

reset of the receiver on B-revision cards re-negotiates the link takes several seconds (a computer eternity)

Set the RX filter = receive only individual pkts & bcast.

set Indication and Interrupt flags , acknowledge any IRQ's

Set our exported functions
