| 3 | A PCMCIA token-ring driver for IBM-based cards |
| 4 | |
| 5 | This driver supports the IBM PCMCIA Token-Ring Card. |
| 6 | Written by Steve Kipisz, kipisz@vnet.ibm.com or |
| 7 | bungy@ibm.net |
| 8 | |
| 9 | Written 1995,1996. |
| 10 | |
| 11 | This code is based on pcnet_cs.c from David Hinds. |
| 12 | |
| 13 | V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com |
| 14 | |
| 15 | Linux V2.2.x presented significant changes to the underlying |
| 16 | ibmtr.c code. Mainly the code became a lot more organized and |
| 17 | modular. |
| 18 | |
| 19 | This caused the old PCMCIA Token Ring driver to give up and go |
| 20 | home early. Instead of just patching the old code to make it |
| 21 | work, the PCMCIA code has been streamlined, updated and possibly |
| 22 | improved. |
| 23 | |
| 24 | This code now only contains code required for the Card Services. |
| 25 | All we do here is set the card up enough so that the real ibmtr.c |
| 26 | driver can find it and work with it properly. |
| 27 | |
| 28 | i.e. We set up the io port, irq, mmio memory and shared ram |
| 29 | memory. This enables ibmtr_probe in ibmtr.c to find the card and |
| 30 | configure it as though it was a normal ISA and/or PnP card. |
| 31 | |
| 32 | CHANGES |
| 33 | |
| 34 | v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com) |
| 35 | Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c |
| 36 | |
| 37 | v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com) |
| 38 | Updated to version 2.2.7 to match the first version of the kernel |
| 39 | that the modification to ibmtr.c were incorporated into. |
| 40 | |
| 41 | v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com) |
| 42 | Address translation feature of PCMCIA controller is usable so |
| 43 | memory windows can be placed in High memory (meaning above |
| 44 | 0xFFFFF.) |
