XOSL

xOSL(meaning Extended Operating System Loader) is the name of a bootloader, which is a program product class that launches operating systems from a bootable device such as a hard disk or floppy drive. The letters are an acronym that stand for eXtended Operating System Loader. xOSL was originally developed by Geurt Vos.

Basic Appeal

xOSL provides a graphical user interface which allows the user to set up and boot a computer into any of 24 different operating systems. xOSL is nondenominational bootloader, owing allegiance to no system in particular, and booting them all equally well.

The xOSL interface installs and uninstalls easily. The xOSL program poses very little risk of permanent damage to existing data. Removing the program can be accomplished with the DOS command fdisk /MBR, which returns the disk to its origianl boot configuration. Generally Xosl resides on it own fat32 patrtition requiring less thn 2mb, and it does not intermingle with other data.

The xOSL solution is highly portable (less than 1mB) and incorporates asily navigable menu boxes and interfaces. The program requires very little time to configure.

note-The 24 system limititation is imposed by the physical space available on the operating system menu. Theoretically, the program could support an infinite number of operating systems. By 'chainloading' the bootloader, users have reported booting vastly more operating systems than the program is claimed to support. (http://www.tprthai.net/xosl.htm)

History

xOSL is free software released under the GPL license. The project was actively developed by Geurt Vos between 1999 and 2001 and spanned four major revisions and two minor revisions after its initial creation.

From its origin in xOSL version 1.0.0, xOSL underwent major changes in ver. 1.1.0, 1.1.1, 1.1.2 and 1.1.3. These revisions were significant departures from one another, and introduced new features to the program. These features ranged from drastic user interface improvements to improved compatibility on diverse hardware platforms.

xOSL ver. 1.1.4 and 1.1.5 only introduced improvements to existing functionality and repaired features that should have been functional in their predecessors. Although their improvements were subtle, they did serve to stabilize a developing protocol, and are the most polished revisions of the original to date.

The project lapsed into a dormant state and was abandoned by its original developer from 2001-2007. xOSL remained available for download and use throughout this period.

urvivability

Despite the lack of active product development, an enthusiastic community of xOSL users began exchanging ideas and product results through the use of Yahoo! Groups and other support sites on the internet. These groups became the foundation of the 'xOSL Culture.' Fact|date=July 2008 The xOSL groups assisted fellow members with advice and accomplishments through the use of xOSL. The original xOSL site was mirrored in multiple locations after its removal by Mikhail Ranish.

The cult-like devotion to xOSL gave credibility to the idea that the future development of xOSL was an inevetability. Other bootloaders such as Lilo and Grub performed effectively, but xOSL survived as time passed without development support or a marketing platform of any kind.

Very few enhancements to the original product occurred during this time, most of them being fairly inconsequential. One such enhancement gave the user the ability to change wallpapers and the image displayed at startup, and like most other revisions, it did not add a great deal to the program in terms of core functionality.

Other revisions included the translation of xOSL into several different languages, including German, Czech and French, among others.

xOSL2

Responding to the demand for an updated xOSL, John Marlowe has continued the development of the product under the XOSL2 title.

The product boasts that it has added CD support, when in fact the original xOSL incorporated installation from a CD device. Visually and functionally, the product is basically unchanged, except for a startup screen that bears the xOSL2 logo instead of the classic xOSL logo. No major enhancements were introduced, except a streamlined CD install process. At this time, development of xOSL2 may be discontinued.

Compatible Formats

Currently xOSL is capable of booting operating systems from a variety of format types. These include, and may not be lmited to-

Windows-

FAT12 (File Allocation Table)
FAT16
FAT32
NTFS (New Technology File System)

Linux-

EXT2
EXT3
ReiserFS

Conclusions

Other reasons for the success of xOSL include its compact size. Its primary location is in the MBR where it references items on the physical hard drive for its GUI and other features. As long a drive is formated in FAT32, xOSL does not require additional partitioning. The FAT32 drive on which xOSL resides does not need to be the first partition of the drive.

Other features include-

* Graphical User Interface
* Full windowing system with mouse and keyboard support
* Resolutions up to 1600x1200
* Configurable mouse speed
* A set of color schemes
* Several color adjustment options
* Password protected boot configuration and settings
* Restart/Reboot/Shutdown

Booting Features

* Up to 24 boot items
* Microsoft file system partition hiding support
* Storing additional keys before booting
* Activate partitions (one per system or one per HD)
* Automatic booting (with timeout)
* Auto boot last operating system
* Password protection per boot item
* Boot master boot record on any drive
* Boot DOS/Windows 9x on any drive
* Hotkey per boot item
* Support for hard disks larger than 8Gb
* Coexists with virtually any other boot manager
* Runs Ranish Partition Manager 2.38 beta 1.91 (ver 1.1.5 and above)
* Master boot record virus protection

The continued development of xOSL is almost entirely dependent on individual user contributions and community participation.
