Visopsys 0.9 released

Visopsys is a hobby OS for x86-compatible PCs, started in 1997.  Version 0.9 was released this morning, and there’s a change log. The summary: This major release offers a subtly updated look, enhanced networking capabilities and associated programs, Unicode support, a software packaging/download/install/uninstall infrastructure with an online ‘store’, a user space window shell, VMware mouse integration, HTTP, XML, and HTML libraries, some C++ and POSIX threads (pthreads) support, ‘pipes’ for interprocess communication, and additional hashing algorithms. Visopsys has a long history on OSNews – the oldest mention being from 2005. It’s been in relatively steady development ever since.

Visopsys 0.8.3 released

It's been a long time since we last covered Visopys - one of the few remaining hobby operating systems still in development - so how about an update? The last version we covered was 0.8 way back in September 2016, but the most recent release is 0.8.3 from August of this year.

This maintenance version features user experience enhancements and reliability improvements, and a more capable Archive Manager program. Bug fixes cover a number of GUI flaws and memory leaks, and some of the low-level network infrastructure code has been refined.

And just in case you forgot all about this operating system:

Visopsys is an alternative operating system for PC compatible computers. In development since 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, pre-emptive multitasking, and virtual memory. Though it attempts to be compatible in a number of ways, Visopsys is not a clone of any other operating system.

It's available from the project's download page.

Visopsys 0.75 Released

Visopsys is an alternative OS for PC-compatibles. Version 0.75 is the third update this year, and is particularly focused on hardware, adding USB 3.0 (XHCI) and APIC interrupt controller support, as well as improved USB 2.0 and hub support. Downloads are available from here, and details are available in the change log

Visopsys 0.74 released

Visopsys has seen a new release.

This maintenance release features enhanced internationalization support with Spanish and German translations, per-user settings, and extensive stability and performance improvements, most notably to the kernel memory, user input, disk I/O, and GUI subsystems.

More details can be found in the changelog.

New website for Visopsys

We report regularly about Visopsys - one of the few hobby operating systems that survived where virtually all the others (SkyOS, Syllable, etc.) died out. They've got a new website, which seems like a nice occasion to give it some attention again.

The bulk of Visopsys is a fully multitasking, 100% protected mode, virtual-memory, massively-monolithic-style kernel. Added to this is a bare-bones C library and a minimal suite of applications - together comprising a small but reasonably functional operating system which can operate natively in either graphical or text modes. Though it's been in continuous development for a number of years, realistically the target audience remains limited to operating system enthusiasts, students, and assorted other sensation seekers.

Visopsys: one man’s vision to build an operating system

"Visopsys (VISual OPerating SYStem) is an alternative operating system for PC-compatible computers, developed almost exclusively by one person, Andy McLaughlin, since its inception in 1997. Andy is a 30-something programmer from Canada, who, via Boston and San Jose ended up in London, UK, where he spends much of his spare time developing Visopsys. We had the great fortune to catch up with Andy via email and ask him questions about Visopsys, why he started the project in the first place, and where is it going in the future."

Visopsys 0.71 Released

Version 0.71 of Visopsys has been unleashed into the wild. "The bulk of this release consists of general bug fixes, and improvements to hardware detection and device drivers, with particular focus on USB. New features include the ability to boot from a USB device (a new USB image is available for download) and the ability to power down the system."

Visopsys 0.7 Released

The 0.7 version of the Visopsys desktop operating system has been released. "More than four years in the making, this is a major new release offering an updated look and a number of new features, including JPEG image support, image resizing, 64-bit disk support, UDF (DVD) filesystem support, and GPT partition table support, as well as lots of new icons, wallpaper images, and file browsing functionality. New administrative applications and functionality have been added, and the ATA/IDE driver has been enhanced, including the ability to better support backwards-compatible SATA controllers. FPU context saving has been improved, and a number of tweaks and bug fixes are also included."

Visopsys 0.7 Preview Released

A preview of the 0.7 release of Visopsys is now available from the preview page. The page is light on details of the new technical features such as JPEG, 64-bit disk, UDF, and GPT support but provides screenshots and a breakdown of the updated look of Visopsys. As always you can try the OS from the 'live' CD image (and yes, after 10 years of development, there's still a basic version that fits on a floppy).

Visopsys 0.69 Released

Visopsys version 0.69 was released today. Four months in the making, this is a maintenance release comprising the final round of tweaks and bug fixes to the 0.6x series of Visopsys, featuring lots of work on the USB subsystem including support for USB mice/keyboards and hubs, tuning of the FAT filesystem driver, usability fixes for various user programs, and loads of OS kernel and C library improvements and bug fixes. As always you can demo Visopsys as a live CD or run a scaled-down version from a floppy disk. Change log is here, and downloads are here.

Visopsys 0.68 Released

The 0.68 release of the Visopsys OS went live today. It's a maintenance release with the usual array of tweaks and bug fixes, plus a focus on disk I/O performance; the software disk caching was re-written, and lookahead/write caching were added to the IDE driver. Another new feature is secure deletion (shredding) of files, partitions, and disks. Change log here and downloads here.

Visopsys 0.67 Released

Version 0.67 of Visopsys was released today, with all the usual bug fixes and tweaks plus two focus areas of improvement: the IDE/ATA disk driver has been 'modernized' with PCI, DMA, and 48-bit addressing support, resulting in a raw I/O performance increase of up to 700%; additionally the Disk Manager (Partition Logic) has been re-engineered and modularized to support the later addition of new disk label types, as well as improved support for MS-DOS logical partitions (moving, creating out-of-order, etc.). Downloads are here, and the change log is here.

Visopsys 0.66 Released

Today marks a new release of the Visopsys operating system, version 0.66. "This is a maintenance release, featuring the ability to resize Windows Vista partitions, more reliable loading on various systems, better exception handling, color text in graphics mode, improvements to the C library, and a number of bugfixes." The changelog has all the details.

Visopsys 0.65 Released

Version 0.65 of the Visopsys operating system was released today. A lot of work has been done on the USB subsystem and underlying UHCI driver - though it's still not 'there' yet it has been re-enabled for the time being. New features were added to the Disk Manager (a.k.a. Partition Logic) including partition copy/paste (same disk or disk-to-disk). And finally, as with the last few releases there's been a focus on improving the GUI code. You can demo Visopsys on a floppy or live CD. Downloads and change log.

Visopsys 0.64 Released

After a couple of months of serious work, Visopsys 0.64 has been released. There are only a handful of new, user-visible features (including right-click context menus and 32-bit .bmp/.ico support). The real focus of this release has been stability, quality, and debugging, plus large scale GUI re-engineering. In addition, graphics mode now works under Bochs 2.3 (as well as Qemu and VmWare).
