ACPI Driver Package version 3.23.07 released

Arca Noae is pleased to announce the immediate availability of our ACPI Driver Package for ArcaOS, OS/2, and eComStation version 3.23.07.

This release contains a fix for a defect that exists in all versions of all SMP kernels which can cause unexplained traps and possible data corruption.

The effect of the defect occurs very rarely and only on multi-CPU systems, but the possibility of seeing it increases on faster and busier systems.

Because of the serious nature of this defect, this update is highly recommended for all SMP kernel users.

The ACPICA module was also updated to the latest version from Intel.

If you have ArcaOS, this driver package is available for download from the Arca Noae website as part of the Support & Maintenance subscription for your ArcaOS product. Please log into your account and see your ArcaOS order details page to access your software.

If you have an Arca Noae OS/2 & eCS Drivers and Software Subscription, this driver package is available for download from the Arca Noae website as part of your Arca Noae OS/2 & eCS Drivers and Software Subscription. Please log into your account in order to access your software.

If you are still running OS/2 and/or eComStation systems and haven’t yet purchased a software subscription, this is a great reason to do so now. It may also be a good time to consider moving up to ArcaOS.

Convenience of shutdown/poweroff in a virtual machine

At one time, shutting down an OS/2 guest under VirtualBox meant full shutdown and virtual powerdown. With recent versions of VirtualBox (5.x), however, this has not been the case.

We’ve noticed, and we’ve done some work to address this.

Did you know that Arca Noae’s ACPI driver runs just fine under these latest builds of VirtualBox? Using the ACPI driver, it is possible to configure the OS/2 (or eComStation) guest machine for complete poweroff using ACPI, just as you might configure a physical workstation.

If you’ve thought that the Arca Noae Drivers and Software subscription didn’t bring value to your virtual OS/2 experience, think again. Now is a great time to subscribe.

Arca Noae joins the UEFI Forum as an Adopting Member

For immediate release:

Leesburg, Virginia, USA

Arca Noae, LLC, a Delaware-based Limited Liability Company, is pleased to announce their membership in the UEFI Forum.

The UEFI (Unified Extensible Firmware Interface) specification defines a new model for the interface between personal-computer operating systems and platform firmware. The interface consists of data tables that contain platform-related information, plus boot and runtime service calls that are available to the operating system and its loader. Together, these provide a standard environment for booting an operating system and running pre-boot applications. Essentially, this layer provides a replacement for the traditional BIOS, and is the future of small computing architecture.

The UEFI Forum is a clearinghouse for all current, related documents pertaining to UEFI, the UEFI specification, and its adoption by manufacturers and software developers.

In addition, the UEFI Forum performs a similar function for ACPI (Advanced Configuration and Power Interface). Arca Noae develops and maintains the current ACPI implementation for the OS/2 and eComStation platform.

Arca Noae is committed to running OS/2 on current hardware. UEFI, like ACPI, is a continuation of the trend to move more functions from the BIOS to the operating system. Arca Noae is looking into how this new technology can be supported under OS/2 in the future.
