The NEAT chipset—New Enhanced AT—was developed by Chips and Technologies for the Intel 80286 and the 80386SX CPU in 1988. The chipset introduced mainboard configuration via the BIOS which superseded the configuration with jumpers. The NEAT chipset also included support for EMS, without the necessity of an EMS ISA expansion card on the 80286. It had great RAM throughput because of bank interleaving and featured UMB memory management, which was completely new at that time and, compared to the MMU of the 80386 (especially the 386SX), didn't slow the CPU down.
