.file extension LGO - OS/2 Boot Logo
File extension LGO description:
The OS/2 Boot Logo format is used under OS/2 Warp versions 3 and 4 for storing the boot logo. The boot logo is the image that is shown at first when OS/2 starts up after a re-boot.
Under Warp 3, the size of the boot logo image is 640x400 pixels. The VGA resolution used at boot time is 640x480. Warp 3 reserves 80lines at the bottom of the screen for showing copyright information. This space cannot be used and thus the size of the boot logo must be 640x400. (Using a 640x480 boot logo under Warp 3 will result in an OS/2 TRAP at system startup.) Warp 4 does not reserve this space and a full-screen 640x480 boot logo may be used under Warp 4. The boot logo file is located on the root of the OS/2 boot drive. The name of the file is OS2LOGO and by default the file has the system attributes hidden, system, and read-only set. The default extension is LGO.

OS/2
OS/2 is a computer operating system, initially created by Microsoft and IBM, then later developed by IBM exclusively. The name stands for "Operating System/2," because it was introduced as part of the same generation change release as IBM's "Personal System/2 (PS/2)" line of second-generation Personal Computers. OS/2 is no longer marketed by IBM, and IBM standard support for OS/2 was discontinued on December 31, 2006. Currently, Serenity Systems sells OS/2 under the brand name eComStation.
OS/2 was intended as a protected mode successor of PC-DOS and Microsoft Windows. Notably, basic system calls were modeled after MS-DOS calls; their names even started with "Dos" and it was possible to create "Family Mode" applications: text mode applications that could work on both systems. Because of this heritage, OS/2 is like Windows in many ways, but it also shares similarities with Unix and Xenix.
OS/2 is also remembered for being one of the first major operating system to have its own advocacy group. Team OS/2 was a grassroots, ad-hoc organization of volunteers, who promoted and supported the operating system and applications designed for it.
