18 This driver uses the cards in the 8390-compatible mode.
19 Most of the run-time complexity is handled by the generic code in
20 8390.c. The code in this file is responsible for
21
22 ultra_probe() Detecting and initializing the card.
23 ultra_probe1()
24 ultra_probe_isapnp()
25
26 ultra_open() The card-specific details of starting, stopping
27 ultra_reset_8390() and resetting the 8390 NIC core.
28 ultra_close()
29
30 ultra_block_input() Routines for reading and writing blocks of
31 ultra_block_output() packet buffer memory.
32 ultra_pio_input()
33 ultra_pio_output()
34
35 This driver enables the shared memory only when doing the actual data
36 transfers to avoid a bug in early version of the card that corrupted
37 data transferred by a AHA1542.
38
39 This driver now supports the programmed-I/O (PIO) data transfer mode of
40 the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
41 That support (if available) is in smc-ez.c.
42
43 Changelog:
44
45 Paul Gortmaker : multiple card support for module users.
46 Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
47 Donald Becker : 6/6/96 correctly set auto-wrap bit.
48 Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
49
50 Note about the ISA PnP support:
51
52 This driver can not autoprobe for more than one SMC EtherEZ PnP card.
53 You have to configure the second card manually through the /proc/isapnp
54 interface and then load the module with an explicit io=0x___ option.
