admtek an983b multiport not supported?

Hello all,
I've been trying to get this card working with the tulip driver on a rh9
(kernel 2.4.20-6) machine.  We have one of these that works in another
identical machine, but (without being able to look at the board itself)
appears to use a different chip.

(slight digression)
The working model looks to have separate eeproms for each port and uses a
different chip; has this:
desc: "DEC|DECchip 21140 [FasterNet]"
vendorId: 1011
deviceId: 0009
subVendorId: 0000
subDeviceId: 0000
The tulip driver shipped with rh9 recognized these as separate interfaces
(separate interrupts for each) and 'just worked'.


The one I have in hand uses an ADMTek AN983B.  I've compiled and loaded the
newest tulip driver (tulip.c:v0.98 1/8/2004) and have run tulip-diag on this
as well.  This is running on a Dell poweredge 400sc with the latest BIOS
(A06).  There is a large heatsink on the card, which might mean the board
has an on-board processor?  (If so, it is unsupported...).  I guess it is
possible these two boards are that much different. ??  This is a cheap no
namer.

I notice from http://www.scyld.com/tulip_devel.html
Current Driver Issues:
"Detecting when the interrupt lines are actually mapped to the reported
IRQs, instead of all being on one IRQ. Almost all x86 motherboard BIOSes
report incorrect IRQ lines for all but the first port on multiport boards.
The best I can come up with storing an alternate possible IRQ value in
struct tulip_private. If the timer code detects that the chip has posted an
interrupt that we haven't gotten, release the primary IRQ and request the
new one. Ugly, especially if we fail requesting the new one. "


This seems like what is happening here. ??

If not,
The stock rh9 driver recognized the card as
desc: "Linksys|Network Everywhere Fast Ethernet 10/100 model NC100"
vendorId: 1317
deviceId: 0985
subVendorId: 1113
subDeviceId: 1216

Manually loading the newest tulip.o with debug=31 produces

I've included gobs of output as I'm not certain as to what is most relevant.
I will provide whatever else might be needed.

Will this card work?  What other troubleshooting steps can I take?  Is this
an issue with the specific kernel, or BIOS or ???  I've had experience with
C, but not much at the driver level and I'm not familiar with the sequence
of events that take place, but am very willing to learn and tinker with the
source (with a little guidance as to starting).  With all that said, I
suspect that the driver will handle this card and I'm just overlooking some
configuration or the like and there isn't any (or little) source level
modification needed.  Any help you all can provide is appreciated.


Thanks,
Thomas
