- ne3210.c
-
- Linux driver for Novell NE3210 EISA Network Adapter
-
- Copyright (C) 1998, Paul Gortmaker.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- Information and Code Sources:
-
- 1) Based upon my other EISA 8390 drivers (lne390, es3210, smc-ultra32)
- 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
-
- The NE3210 is an EISA shared memory NS8390 implementation. Shared
- memory address > 1MB should work with this driver.
-
- Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched
- around (or perhaps there are some defective/backwards cards ???)
-
- This driver WILL NOT WORK FOR THE NE3200 - it is completely different
- and does not use an 8390 at all.
-
- Updated to EISA probing API 5/2003 by Marc Zyngier.
