/* orinoco_tmd.c
- *
+ *
* Driver for Prism II devices which would usually be driven by orinoco_cs,
* but are connected to the PCI bus by a TMD7160.
*
* other provisions required by the GPL. If you do not delete the
* provisions above, a recipient may use your version of this file
* under either the MPL or the GPL.
+
+ * Caution: this is experimental and probably buggy. For success and
+ * failure reports for different cards and adaptors, see
+ * orinoco_tmd_pci_id_table near the end of the file. If you have a
+ * card we don't have the PCI id for, and looks like it should work,
+ * drop me mail with the id and "it works"/"it doesn't work".
+ *
+ * Note: if everything gets detected fine but it doesn't actually send
+ * or receive packets, your first port of call should probably be to
+ * try newer firmware in the card. Especially if you're doing Ad-Hoc
+ * modes
*
* The actual driving is done by orinoco.c, this is just resource
* allocation stuff.
*
* This driver is modeled after the orinoco_plx driver. The main
- * difference is that the TMD chip has only IO port ranges and doesn't
- * provide access to the PCMCIA attribute space.
+ * difference is that the TMD chip has only IO port ranges and no
+ * memory space, i.e. no access to the CIS. Compared to the PLX chip,
+ * the io range functionalities are exchanged.
*
* Pheecom sells cards with the TMD chip as "ASIC version"
