In addition, the Security System pane provides configuration support for USB keyboard and mouse. ![]() When the keyswitch is locked, the CD is ejected. ![]() Obsolete Xserve G5’s keyswitch security prevents unauthorized hot-plugging and mounting of a USB or FireWire hard drive. The KeyLargo IC provides two USB root hubs, a UATA interface, and support for the LED display, also used in PowerMac G4’s. It provides all the I/O functions except Ethernet and FireWire. Obsolete The KeyLargo custom IC, the third major component of the Xserve architecture, is connected to the main PCI bus through a dedicated PCI-to-PCI bridge. ObsoleteK2 is an older IO controller used with PowerMac G5’s, potentially obsolete? Nothing to do with Intel Macs at least.Īn island in Hawaii, also an Obsolete PPC ATA controller used in older Macs. Obsolete K2 is an older IO controller used with PowerMac G5’s, potentially obsolete? Nothing to do with Intel Macs at least. GMA X3100 always refers to the mobile version, there is no known support for the GMA 3100 (Without the X), the desktop version.īuilt-in framebuffer for Integrated Intel (GMA950?) graphics cards. Kernel extension for GMA X3100 graphics cards. Kernel extension for GMA 950 (mobility and desktop versions). *note: this does not provide functionality from the kext, only stops the kernel panic from occuring. Used for speedstepping on real Macs, known to cause kernel panics on OSx86 systems that do not have a properly patched DSDT. Integrated Inter-chip Sound, an electrical serial bus interface standard used for connecting digital audio devices togetherĭriver for the infrared port used by the Apple Remote. Inter-Integrated Circuit, used for connecting low-speed peripherels to a motherboard. High Precision Event Timer: Complicated, see HID = Human Interface Device, mouse controls. Human Interface Device = Keyboard controls. High Definition Audio kext, contains other audio kexts including: AppleHDAController.kext, IOHDAFamily.kext, and AppleHDAHALPlugin.bundle. Presumably for dynamic GPU switching on things like the Macbook Pro which has two GPUs, has to do with controlling brightness as well. Graphics warning? Localizable strings and binary make reference to properly plugging the graphics card in, binary has nothing but button/alert text. Obsolete PPC Only, references to Jmicron in the binary, most likely has to do with flashing nvram as the name says. General filesystem driver for HFS+, Apple RAID. Nothing to do with the Apple Federal Credit Union, going through ASCII strings in the binary seems to indicate some form of sensor polling for PowerPC I2C Interface sensors. Possibly used for EFI initialization of graphics card ROM BIOS. Obsolete PPC Only, temperature sensor, references in binary to PPCI2CInterface Obsolete PPC Only, Most likely to do to with the fan, references in the binary to KeyLargo. The BMC manages the interface between system management software and platform hardware.īacklighting support for Notebook displays, ie: changing the brightness/power settings of the lcd. The BMC is the intelligence in the Intelligent Platform Management Interface (IPMI) architecture. Thermal management controller and voltage monitor.Ī baseboard management controller (BMC) is a specialized microcontroller embedded on the motherboard of a computer, generally a server. ![]() ![]() Obsolete, used for Apple Desktop Bus mice.ĪCPI-Compliant remote thermal monitor with integrated fan controller. Obsolete Used for Apple Desktop Bus keyboards. (No idea what this actual kext does, doesn’t really matter) Used primarily on the Apple Macintosh platform, ADB equipment is still available but not supported by most Apple hardware manufactured since 1999. Obsolete Apple Desktop Bus (or ADB) is an obsolete bit-serial computer bus connecting low-speed devices to computers. Obsolete Used for serial connectors/adaptorsĪCPI is the standard for Power Management in computers, interacts with the EFI in real Macs, has to do with controlling interrupts (IRQ), non-volatile RAM, controlling sleep, thermal settings, controlling the RTC, contains other kexts including AppleACPIButtons.kext, AppleACPIIEC.kext, AppleACPIPCI.kext. Presumably for ATI Radeon Native Drivers. Presumably used for the Algebraic Logic Functional Programming Language.ĪTI Native Driver for ATI Radeon HD 6000 Series GPUĪTI Native Driver, presumably for non-Radeon cards.
