Some computer designs have used non-button cell batteries, such as the cylindrical "1/2 AA" used in the Power Mac G4 as well as some older IBM PC compatibles, or a 3-cell nickel–cadmium (Ni–Cd) CMOS battery that looks like a "barrel" (common in Amiga and older IBM PC compatibles), which serves the same purpose. These motherboards often have ...
Typical POST screen (AMI BIOS) Typical UEFI-compliant BIOS POST screen (Phoenix Technologies BIOS) Summary screen after POST and before booting an operating system (AMI BIOS) A power-on self-test ( POST ) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on.
The standard encoding of the keyboard that offers the INT 16 h is a US keyboard. To adapt the coding of the INT 16h to another type of keyboard (for example, an international keyboard), the code must analyze the scan-code of the key pressed, and then perform suitable interpreting.
CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

The Smart Battery System defines the SMBus connection, the data that can be sent over the connection (Smart Battery Data or SBD), the Smart Battery Charger, and a computer BIOS interface for control. In principle, any battery operated product can use SBS. Texas Instruments BQ20Z45: SBS 1.1-compliant gas gauge and protection enabled with ...
The first HP Windows Mobile 6 device, the iPAQ 500 Series Voice Messenger, with the Windows Mobile 6 Standard Operating System (WM6), and numeric pad, was released in the same year. The entire iPAQ line was completely revamped by the introduction of five new iPAQ series to complement the introduction of the iPAQ 500 Series Voice Messenger ...
The LPC bridge provides a data and control path to the super I/O (the normal attachment for the PS/2 keyboard and mouse, parallel port, serial port, IR port, and floppy controller). SMBus controller. DMA controller. The 8237 DMA controller allows ISA or LPC devices direct access to main memory without needing help from the CPU. PIC and I/O APIC.
RF CMOS is also used in the radio transceivers for wireless standards such as GSM, Wi-Fi, and Bluetooth, transceivers for mobile networks such as 3G, and remote units in wireless sensor networks (WSN). [25] RF CMOS technology is crucial to modern wireless communications, including wireless networks and mobile communication devices.
