16 This is a device driver for the Allied Telesis AT1700, and
17 Fujitsu FMV-181/182/181A/182A/183/184/183A/184A, which are
18 straight-forward Fujitsu MB86965 implementations.
20 Modification for Fujitsu FMV-18X cards is done by Yutaka Tamiya
21 (tamy@flab.fujitsu.co.jp).
24 The Fujitsu MB86965 datasheet.
26 After the initial version of this driver was written Gerry Sawkins of
27 ATI provided their EEPROM configuration code header file.
28 Thanks to NIIBE Yutaka <gniibe@mri.co.jp> for bug fixes.
30 MCA bus (AT1720) support (now deleted) by Rene Schmit <rene@bss.lu>
33 The MB86965 has a design flaw that makes all probes unreliable. Not
34 only is it difficult to detect, it also moves around in I/O space in
35 response to inb()s from other device probes!
