	Thanks for the suggestion.. however, eepro100-diag doesn't seem
	to interface with the adapter correctly... when I first tried to
	run eepro100-diag, it reported:

------------------------------------------------------------------------------
[root@dhcp-dyn05 eepro100]# ./eepro100-diag

Unable to find a recognized card in /proc/pci.
If there is a card in the machine, explicitly set the I/O port address
  using '-p <ioaddr> -t <chip_type_index>'
 Use '-t -1' to see the valid chip types.
------------------------------------------------------------------------------

	So I loooked in the syslog file and found:

------------------------------------------------------------------------------

------------------------------------------------------------------------------

	OK, so then I run "eepro100-diag -p 0xd88af000 -t 4 -f -e"...

------------------------------------------------------------------------------
[root@dhcp-dyn05 eepro100]# ./eepro100-diag -p 0xd88af000 -t 4 -f -e
eepro100-diag.c:v2.05 6/13/2001 Donald Becker (becker@scyld.com)
 http://www.scyld.com/diag/index.html
Assuming a Intel i82562 Pro/100 V adapter at 0xd88af000.
Intel EtherExpress Pro 10/100 EEPROM contents:
  Station address FF:FF:FF:FF:FF:FF.
  Board assembly ffffff-255, Physical connectors present: RJ45 BNC AUI MII
  Primary interface chip i82555 PHY #-1.
    Secondary interface chip i82555, PHY -1.
   Sleep mode is enabled.  This is not recommended.
   Under high load the card may not respond to
    PCI requests, and thus cause a master abort.
------------------------------------------------------------------------------

	It doesn't identify the address, board assembly or connectors
	properly... it also always thinks the adapter is active (even
	in single user mode)... using '-ee' produces a table with all
	bits set, e.g.

------------------------------------------------------------------------------
EEPROM contents, size 256x16:
    00: ffff ffff ffff ffff ffff ffff ffff ffff
	     [...]
  0xf8: ffff ffff ffff ffff ffff ffff ffff ffff
 *****  The EEPROM checksum is INCORRECT!  *****
  The checksum is 0xFF00, it should be 0xBABA!
------------------------------------------------------------------------------

	Perhaps I'm missing something obvious, but any other suggestions
	would be appreciated.

								thanks,
