In computing, the reset vector is the default location a central processing unit will go to find the first instruction it will execute after a reset. The reset vector is a pointer or address , where the CPU should always begin as soon as it is able to execute instructions.
Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings. It is traditionally called CMOS RAM because it uses a volatile, low-power complementary metal–oxide–semiconductor (CMOS) SRAM (such as the Motorola MC146818 [1] or similar) powered by a small battery when system and standby power is off.

Both models came with either integrated or discrete graphics. It uses the Radiance pattern as part of HP's Imprint finish, with some models featuring other unique patterns. Model numbers range from dv2700 to dv2899. The Pavilion dv2700 and the rest of the Pavilion dv2000 series were replaced by the 14.1" dv4 series in mid-to-late September 2008.

Generally, a TTL output does not rise high enough to be reliably recognized as a logic 1 by a CMOS input, especially if it is only connected to a high-input-impedance CMOS input that does not source significant current. This problem was solved by the invention of the 74HCT family of devices that uses CMOS technology but TTL input logic levels.
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
The HP Pavilion dv4 is a model series of laptops manufactured by Hewlett-Packard Company that features a 14.1" diagonal display.
The 6,700 lbf (30 kN) ALF 502R-3 variant initially powered the quad-engine British Aerospace 146, which entered service in 1983 and became the ALF 502's biggest customer. A total of 1,019 ALF 502 engines of all variants were produced. The LF 507 series based on the ALF 502R was announced in September 1988.
