From 84b256a66360cedc25eb6e2ac6f167ca9778307b Mon Sep 17 00:00:00 2001 From: Bernhard Rosenkraenzer Date: Sun, 20 Nov 2005 00:50:37 -0500 Subject: Input: wistron - add support for Acer Aspire 1500 notebooks Also fix a potential issue with some notebooks: The current code assumes the response to bios_wifi_get_default_setting is either 1 (disabled) or 3 (enabled), or wifi isn't supported. The BIOS response appears to be a bit field w/ 0x1 indicating hardware presence, 0x2 indicating actiation status, and the other 6 bits being unknown/reserved -- with the patch, these 6 bits are ignored.
