Hmmm, perhaps I made an incorrect assumption.
I was guessing that the first was a PCI plug-in card, while the only the
second was on the motherboard.

Are both of these on the motherboard?  Both use a Tyan subsystem ID.

If both are on the motherboard, they should both have the same PCI ID.

Note the "982" ID first showed up on a dual port card.  I assumed that
it meant "980" with "2" ports.  There have been reports that "982" has
been used with single port server boards as well.

The problem vortex-diag has with reading the EEPROM is likely that the
board design is missing a bias resistor that allow the driver to figure
out the serial EEPROM address size, 6 or 8 bits.  If it's on a
Tyan-designed motherboard, it's very likely that Tyan skipped that
section on the hardware design guide because they didn't understand why
the resistor was needed.
