On 04/09/2002 miray Software officially introduced the version 0.93 of the operating system µnOS. The company also announced a new version of the underlying realtime microkernel, which will be available as a stand-alone product in the future.

The slim and widely scalable client/server operating system µnOS is based on a very small realtime microkernel. The version 0.93 has been improved in many aspects. Besides others, it provides a smaller microkernel of only 70 KB, extended hardware support, support of up to 4 GB of RAM, a high level of stability and dynamic device drivers. Furthermore, new applications have been added to µnOS 0.93 like a file browser, a memory guard, a shutdown manager and a display manager.

As usual with previous versions of µnOS, there is again a free demo version of µnOS 0.93 available for download under http://www.miray.de/download/demodisk.html. This demo version contains a graphical user interface and numerous demo applications. As it fits just on a 1.44 MB floppy, it's not necessary to make any changes to the harddisk.

The µnOS 0.93 demo is not only available as disk image for creating a bootdisk but also as ISO image for creating a bootable CD-ROM. Further, there is the possibility of purchasing a bootable CD-ROM from miray with the µnOS 0.93 demo version on it under http://www.miray.de/order/system_cv.html.

The version 0.93 of µnOS is based on the original microkernel. Based on this microkernel, miray developed a fundamentally improved successor during the recent months. This new realtime microkernel, named "Sphere 2.0", will be officially presented by miray within the next weeks. The new Sphere 2.0 microkernel is significantly smaller, faster and more powerful. Independent from µnOS it will also be available as a stand-alone realtime microkernel. In the middle of 2002, Sphere 2.0 will also support more processors. Currently Sphere 2.0 runs on all Intel-IA32- and AMD-Élan-processors.
