Allied Telesyn AT-2000T Plus Ethernet NIC:

Normal configuration (don't know if it can be changed -- see #Notes):

  • IRQ 10
  • I/O 0300 - 031F
  • bad (Block ADdress??) ??
  • Win95 Driver: NE2000 Compatible
  • Linux Driver: See #Linux_Driver_Notes

Update (3/5/05): When attempting to install one of these cards (maybe without the T?) on a Win98 box, in the Windows card resources, IRQ 3 and I/0 200-21F were shown—I don't know if Windows (98) actually detected that or "assumed" those were the settings based on a standard configuration (0). The closest driver available on the Win98 install disk (was that the AT-2000 Plus??) did not seem to work--maybe if I had changed the parameters to IRQ 10, I/O 0300-031F. From below, you need to use a special program to change parameters like the IRQ and I/O, I didn't have that program immediately at hand, so didn't try it.

I'm forgetting how to do things in Windows. I found conflicts between this card and the joystick port and something else. In the bios, I set IRQ 3 to ISA (or whatever, instead of PNP). I deleted the joystick--when I rebooted, the joystick was reinstalled but with a different I/O address.

Aside re "bad" -- I don't know what this stands for yet -- when installing the NIC in Mandrake and setting the parameters manually, there was a line to enter a "bad" (or was it Vector Linux?)

OEM driver: Not sure, none found at www.alliedtelesyn.com, the 2000pnp driver does not work.

Wrote to Allied Telesyn (email) on 2 Dec 2002 -- first tried their web mail support request -- it didn't work, then sent mail to postmaster at www.alliedtelesyn.com.

UPDATE: Never got a response, tried writing again today (5 Feb 2003) by various means (support@alliedtelesynPLEASENOSPAM.com, feedback on various answers in their knowledge base).

There is a packet driver -- not sure how to use a packet driver under Linux, but apparently it can be done -- will have to do some digging.

See AboutThesePages.



The AT2000 (without the T Plus) can be set for different IRQs and I/O addresses (and maybe memory address blocks) via a dos program: diag.exe. The program comes in the driver package (oops, closed that window, lost the URL -- do a Google search on Allied Telesyn and AT2000.)

The LRP (Linux Router Project) (see http://pigtail.net/LRP/swap.html) provides helpful information and utilities for doing so. Their de220 floppy is an image that includes DR dos and diag.exe in an image file that can be used to create a bootable floppy to configure the AT2000 and several other ne2000 compatible cards.

So far, I have not been able to get diag.exe to find or configure the AT2000T Plus (I don't know whether diag.exe is incompatible with the AT2000T Plus or if the particular card I've been testing recently is bad), nor have I found an alternate utility for the AT2000T Plus, nor do I know the memory block address for the AT2000T Plus. I think that if I knew that I could set up the AT2000T Plus under Mandrake 9.0, because when I do the right thing to have it let me manually set the card parameters, there is a space to enter the IRQ (10) the I/O Address (which I enter as 0x300 (and it seems to set the range to 300 to 31f based on feedback from ifconfig or some other utility (ip ?)), and the third parameter is "bad" which I assume is block address and I don't know what to enter.
