diskless boot with eepro fails

[dman]

I'm having problems with grub booting a certain diskless terminal.  It
has an Intel eexpress ISA NIC.  When I start grub (from a floppy) with
the eepro driver included, I get this output on-screen :

    dhcp
    Probing...[EEPRO]
    Error 12: Invalid device requested

    Press any key to continue ...

If I run the 'eexpress' program from Donald Becker I get this output :

    EtherExpress found at 0x300, station address 00 aa 00 4a 01 b3, IRQ 10
    EEPROM checksum is 0xbaba, which is correct

That MAC matches the sticker on the card.

I checked the etherboot package and found that grub's eepro driver is
identical to the last two releases of etherboot.  What could be the
problem here, and how might I work around it?

TIA,
