==Architecture==
The Jazz systems were designed to partially comply with the [[Advanced RISC Computing]] (ARC) standard, and each used the ARC firmware to boot Windows NT.<ref name="f124">{{cite web | title=LinuxMIPS | website=web.archive.org | date=2007-04-17 | url=https://web.archive.org/web/20080505015443if_/http://www.linux-mips.org/wiki/Jazz | access-date=2024-06-25}}</ref> Other operating systems were also ported to various Jazz implementations, such as [[RISC/os]] to the MIPS Magnum.

The Jazz architecture includes:
* a MIPS [[R4000]]/[[R4400]] or compatible microprocessor
* an [[Extended Industry Standard Architecture|EISA]] bus
* a [[framebuffer]] for video output (the [[G364 framebuffer]])
* [[PS/2 connector]]s for mouse and keyboard
* a floppy-disk controller
* onboard 16-bit sound system
* onboard [[National Semiconductor]] [[SONIC (Ethernet controller)|SONIC]] Ethernet
* onboard [[NCR 53C9x]] SCSI chipset for [[hard disk]] and [[CD-ROM]] interface
* standard IBM AT [[Serial port|serial]] and [[parallel port]]s
* IBM AT-style time-of-year clock

This design was simple enough and powerful enough that a majority of Windows NT-capable MIPS systems were based on modified versions of the Jazz architecture. A list of systems which more or less were based on Jazz includes:
* [[MIPS Magnum]] (R4000 PC-50 and SC-50 versions)
* [[Acer PICA]]{{snd}} uses [[S3 Graphics|S3]] videocard
* [[Olivetti]] M700{{snd}} has different video and sound system
* [[NEC RISCstation]]{{snd}} Jazz with [[Peripheral Component Interconnect|PCI]]
