Operating System Overview
UnoDOS is a new family of graphical operating systems that originated as a 16-bit real-mode OS written in x86 assembly. It has evolved into a contract-driven family with ports for home computers, consoles, handhelds, single-board computers, and phones. The flagship version, pc64, operates bare-metal on modern 64-bit PCs, utilizing its own drivers, network stack, browser, office suite, compiler, and hypervisor.
Platform Support and Booting
Prebuilt images are available for every supported platform, including hybrid ISO/USB disk images for modern PCs, cartridge ROMs for consoles, disk images for home computers, and SD-card payloads for single-board computers. pc64 is designed to boot bare-metal on most x86-64 PCs manufactured since approximately 2007. It uses UEFI for initial boot on modern machines, then takes over with its own drivers, and also supports legacy-BIOS systems with a hybrid disk image.
User Interface and Applications
The UnoDOS shell is built on unoui, a cross-platform widget toolkit, featuring a windowed desktop with a taskbar, virtual desktops, window snapping, and an Alt-Tab switcher. It offers ten switchable themes, including modern flat designs and retro looks like Mac OS 7 and Windows 3.1. Text rendering includes kerned, anti-aliased TrueType fonts. The OS includes UnoWord, UnoCalc, and UnoShow, an Office 97-class suite that reads and writes Microsoft binary formats (.doc, .xls, .ppt) via the unodoc library. A browser with HTML, Markdown, and CSS rendering, cookies, and cache is also integrated.
