Intel 440BX
The Intel 440BX (codenamed Seattle), is a chipset from Intel, supporting Pentium II, Pentium III, and Celeron processors. It is also known as the i440BX and was released in April 1998. The official part number is 82443BX.
Features
The 440BX originally supported Slot 1 and later Socket 370 Intel P6-based processors in single and SMP configurations at speeds of up to 1 GHz (and potentially up to 1.4 GHz with certain unsupported modifications, up to 1.7 GHz can be achieved using Front Side Bus speeds higher than 133 MHz and appropriate cooling). Its southbridge counterpart is the PIIX4E.
History
The Intel 440BX is the third Pentium II chipset released by Intel, succeeding the 440FX and 440LX. With the new 100 MHz front side bus, Pentium II CPUs were able to scale better in performance by reducing the difference between processor clock and bus speed. The previous 66 MHz bus had become a serious bottleneck and dated back to the first Pentium "Classic" chipsets.
The 440BX had two closely related chipset peers; the 440ZX and 440MX. 440MX is a mobile chipset for laptops, although a number of notebooks did use 440BX. 440ZX is a cost-reduced version of 440BX. It has a lower maximum RAM limit resulting from having support for only 2 RAM banks. The 440ZX-66, designed for Intel Celeron processor, is limited to 66 MHz FSB speed.

Intel Corporation (better known as Intel) is an American multinational technology company headquartered in Santa Clara, California. Intel is one of the world's largest and highest valued semiconductor chip makers, based on revenue. It is the inventor of the x86 series of microprocessors, the processors found in most personal computers. Intel supplies processors for computer system manufacturers such as Apple, Samsung, HP and Dell. Intel also makes motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphics chips, embedded processors and other devices related to communications and computing.
Intel Corporation was founded on July 18, 1968 by semiconductor pioneers Robert Noyce and Gordon Moore and widely associated with the executive leadership and vision of Andrew Grove, Intel combines advanced chip design capability with a leading-edge manufacturing capability.

Intel 80188
The Intel 80188 microprocessor was a variant of the Intel 80186. The 80188 had an 8-bit external data bus instead of the 16-bit bus of the 80186; this made it less expensive to connect to peripherals. The 16-bit registers and the one megabyte address range were unchanged, however. It had a throughput of 1 million instructions per second.
Description
Features and performance
The 80188 series was generally intended for embedded systems, as microcontrollers with external memory. Therefore, to reduce the number of chips required, it included features such as clock generator, interrupt controller, timers, wait state generator, DMA channels, and external chip select lines. While the N80188 was compatible with the 8087 numerics co-processor, the 80C188 was not. It didn't have the ESC control codes integrated.
The initial clock rate of the 80188 was 6 MHz, but due to more hardware available for the microcode to use, especially for address calculation, many individual instructions ran faster than on an 8086 at the same clock frequency. For instance, the common register+immediateaddressing mode was significantly faster than on the 8086, especially when a memory location was both (one of the) operand(s) and the destination. Multiply and divide also showed great improvement, being several times as fast as on the original 8086 and multi-bit shifts were done almost four times as quickly as in the 8086.
