'''Baget''' RTOS ({{langx|ru|ОСРВ Багет}}) is a [[Real-time operating system|real-time]] [[operating system]] developed by the [[Scientific Research Institute of System Development]] of the [[Russian Academy of Sciences]] for a [[MIPS architecture]] (Baget-MIPS variant) and [[Intel Corporation|Intel]] [[board support package]]s (BSPs) ([[x86]] architecture). Baget is intended for software execution in a [[Hard real-time|''hard'' real-time]] [[embedded system]]s (firmware).

[[X Window System]] ([[Client–server model|client and server]]) was ported to Baget. It also has [[Ethernet]] support ([[Network File System (protocol)|Network File System]] (NFS), [[File Transfer Protocol]] (FTP), [[Telnet]] protocols), long filename [[File Allocation Table]] (VFAT) and a [[tar (file format)|tar]] file systems, [[floppy disk]] drive (FDD) and [[hard disk drive]] (HDD) driver support. Several supported network cards are limited by some [[Realtek]] [[Industry Standard Architecture]] (ISA) and [[Peripheral Component Interconnect]] (PCI) cards.

The development process is based on the following principles:
* [[international standard]]s compliance
* [[Porting|portability]]
* [[Scalability]]
* [[Microkernel]]
* [[Object-oriented programming]]
* [[Cross-platform]] development

== Standards compliance ==
* Portable Operating System Interface ([[POSIX]]) 1003.1, standard ([[application programming interface]] (API)),
* [[C (programming language)|C]] standard [[programming language]] and [[Library (computing)|libraries]].
