This module searches BIOS space for a 4-byte signature and then does a call to this address with:
ax = 0x9610 bl = 0x35 bh = 0x00 (switch off), 0x01 (switch on), 0x02 (check if enabled in BIOS) and states that it was produced from reverse engineering 'wbutton.sys' for a 'Fujitsu Siemens Amilo M 7400' laptop. Hopefully this BIOS call might actually be exposed through ACPI instead. -- hotkey support for fujitsu siemens amilo m7400 laptop https://launchpad.net/bugs/48547 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
