Thanks for the response.  Here's more info:

[root@boulder vortex]# ./vortex-diag -aee -p 0xff80

Assuming a 3Com Generic Vortex/Boomerag/Cyclone adapter at 0xff80.
The Vortex chip may be active, so FIFO registers will not be read.
To see all register values use the '-f' flag.
Initial window 7, registers values by window:
  Window 0: 0000 0000 0000 0000 0000 00bf 0000 0000.
  Window 1: FIFO FIFO 0000 2000 8000 00ff 3ffc 2000.
  Window 2: a000 5b24 9d73 0000 0000 0000 00de 4000.
  Window 3: 001b 0141 0000 0000 e10a bfff 3fff 6000.
  Window 4: 0000 02d3 0000 0c80 0000 8882 0000 8000.
  Window 5: 1ffc 1ffc 00de 1ffc 0007 02de 00de a000.
  Window 6: 0000 0000 0000 5b00 0000 157c 1d6d c000.
  Window 7: 0000 0000 0000 0000 8000 00ff 0000 e000.
Vortex chip registers at 0xff80
  0xFF90: **FIFO** 00000000 00008000 *STATUS*
  0xFFA0: 00200000 0180b008 00240000 fd7c0000
  0xFFB0: ffffffff ffffffff ffffffff ffffffff
 Indication enable is 00de, interrupt enable is 02de.
 No interrupt sources are pending.
 Transceiver/media interfaces available:  100baseTx 10baseT.
Transceiver type in use:  100baseTX.
 MAC settings: half-duplex.
Maximum packet size is 0.
 Station address set to 00:a0:24:5b:73:9d.
 Configuration options 00de.
EEPROM contents (64 words, offset 0):

 The word-wide EEPROM checksum is 0x63a4.
Saved EEPROM settings of a 3Com Vortex/Boomerang:
 3Com Node Address 00:A0:24:5B:73:9D (used as a unique ID only).
 OEM Station address 00:A0:24:5B:73:9D (used as the ethernet address).
 Manufacture date (MM/DD/YYYY) 1/28/1996, division 6, product BU.
 Options: negotiated duplex, link beat required.
  Vortex format checksum is correct (0016 vs. 0016).
  Cyclone format checksum is correct (00 vs. 00).
  Hurricane format checksum is correct (00 vs. 00).
