PMU(4) BSD Kernel Interfaces Manual PMU(4) NAME
pmu -- support for Power Management Units found in all Apple laptops and some desktop Power Macintosh computers SYNOPSIS
pmu* at obio? nadb* at pmu? battery* at pmu? smartbat* at pmu? DESCRIPTION
The pmu driver provides support for the Power Management Unit found in Apple laptops and some desktop Power Macintosh computers. Functions controlled by the PMU include the real time clock, ADB, power, batteries, on some laptops like the PowerBook 3400c and similar machines it also controls hotkeys and display brightness, on others it provides an iic(9) bus and on some it controls CPU speed. On many older machines it also provides access to some non-volatile memory and thermal sensors. Not all those features are present on all machines, for instance Power Macintosh G4 and later machines don't have ADB, many more recent laptops have display brightness and backlight control built into the graphics controller instead of the PMU, only a few older PowerBooks use the PMU for CPU speed control and newer machines use a different way to access non-volatile memory. However, all known PMUs so far provide a real time clock and power control. Notes by model Real time clock and power control are present and supported on all machines that can run NetBSD/macppc, ADB is supported when present. PowerBook 2400, 3400c, and 3500 Battery status and thermal sensors found on the mainboard and in the battery pack are supported by the battery(4) driver, val- ues can be read via envsys(4). Hotkeys for brightness control are supported, CPU speed control and parameter RAM are present but unsupported. Power Macintosh G4 ADB is not present, iic(9) is present but unsupported. SEE ALSO

Some features are currently unsupported, like the iic(9) bus, access to parameter RAM and CPU speed control. BSD

AKBD(4) BSD Kernel Interfaces Manual AKBD(4) NAME
akbd -- Apple Desktop Bus keyboard driver for wscons SYNOPSIS
akbd* at obio? wskbd* at akbd? console ? options ALTXBUTTONS options CAPS_IS_CONTROL options FORCE_FUNCTION_KEYS DESCRIPTION
This driver provides the wscons(4) driver with support for Apple Desktop Bus keyboards. To work around the limited number of buttons found on most ADB mice, one can map key sequences to trigger mouse button events. To map Option+1, Option+2, Option+3 to mouse buttons 1, 2, and 3 respectively, add the following line to your kernel configuration file: options ALTXBUTTONS On macppc systems it is possible to tweak the keyboard driver to treat the caps lock key on an ADB keyboard as a control key. This requires special remapping because of ADB's strange emulation of a mechanically-locked key. To enable this code add the following line to your kernel configuration file: options CAPS_IS_CONTROL On macppc PowerBooks, several function keys double as "hot keys" (brightness, volume, eject) when the Fn modifier is held down. Mac OS X likes to reprogram the keyboard controller to send hot key events when Fn is not held down and send function key events when it is. To transform the non-keyboard "button" events back into function key events, place the following line in your kernel configuration file: options FORCE_FUNCTION_KEYS SUPPORTED HARDWARE
NetBSD is known to support the following ADB keyboards: o On-board keyboards on PowerBook models o Apple Standard Keyboard o Apple Keyboard II o Apple Extended Keyboard o Apple Extended Keyboard II o Apple Adjustable Keyboard o Most third-party ADB keyboards are supported SEE ALSO
adb(4), wscons(4), wskbd(4), wsconsctl(8) BUGS
The number pad on extended keyboards does not send out the proper key codes for many applications. The LEDs on extended keyboards are not functional under NetBSD. BSD
