For Intel Pentium III CPUs, the serial number is returned in the EDX:ECX registers. For Transmeta Efficeon CPUs, it is returned in the EBX:EAX registers. And for Transmeta Crusoe CPUs, it is returned in the EBX register only. Note that the processor serial number feature must be enabled in the BIOS setting in order to function.
ICH - 82801AA. The first version of the ICH was released in June 1999 along with the Intel 810 northbridge.While its predecessor, the PIIX, was connected to the northbridge through an internal PCI bus with a bandwidth of 133 MB/s, the ICH used a proprietary interface (called by Intel Hub Interface) that linked it to the northbridge through an 8-bit wide, 266 MB/s bus.
The Pentium III was the first x86 CPU to include a unique, retrievable, identification number, called Processor Serial Number (PSN). A Pentium III's PSN can be read by software [ 20 ] through the CPUID instruction if this feature has not been disabled through the BIOS .
Low Pin Count interface Winbond chip Trusted Platform Module installed on a motherboard, and using the LPC bus. The Low Pin Count (LPC) bus is a computer bus used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the BIOS ROM (BIOS ROM was moved to the Serial Peripheral Interface (SPI) bus in 2006 [1]), "legacy" I/O devices (integrated into Super I/O ...
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module. Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
ITE Super I/O chip (IT8712F) SMSC™ (now Microchip) Super I/O chip (FDC37M813) on IBM motherboard Super I/O (sometimes Multi-IO) [ 1 ] is a class of I/O controller integrated circuits that began to be used on personal computer motherboards in the late 1980s, originally as add-in cards , later embedded on the motherboards.
Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
A debug port is a diagnostic interface (akin to a computer port) included in an electronic system or integrated circuit to aid design, fabrication, development, bootstrapping, configuration, debugging, and post-sale in-system programming.
