The maximum theoretical resolution limit for Panorama is 65535x65535x32bpp. However, other factors outside of Panorama may significantly limit this.
The maximum resolution for the Custom Resolution module is 4095x4095x32bpp. This is due to 12 bits used to store the resolution in the EDID and the various BIOS mode tables.
The primary limiting factor for what resolutions Panorama will support is in the video hardware itself and the video BIOS that controls it. Panorama has been tested at resolutions up to 3840x2160x32bpp at 60Hz and works perfectly provided that the BIOS supports the desired resolution.
More information regarding Panorama’s capabilities may be found in the wiki.
The Unix Compatibility Subsystem is built around a component known as kLIBC, which is itself a project hosted at OS/2 Netlabs. The subsystem consists of a collection of applications generally ported from Linux, and when built from source using the gcc compiler, become native OS/2 applications.
This subsystem brings a whole new world of modern, maintained applications to the OS/2 platform.
While this subsystem is installed as part of ArcaOS, earlier OS/2 Warp 4 distributions may take advantage of this environment and run these applications as well. All that is required to get started is to download and install Arca Noae Package Manager (ANPM), available from this page.
See this wiki page for more information about the Unix Compatibility Subsystem.
OS/2 has been around for a long time, and one of the great strengths of the platform is a strong user-to-user community of professionals and power users willing to assist in solving problems and giving quality advice.
Several good places exist on the internet, depending upon the type of information desired and one’s preferred method of communication (mailing list, newsgroup, or forum). Here is a sampling of links to get started:
OS/2 VOICE (see the Resources menu)
OS/2 World (see the forums)
eComStation mailing list at Yahoo! Groups
eCS-Technical mailing list at Yahoo! Groups
This is a known issue for DOS and 16-bit Windows sessions (Win-OS/2) under OS/2, eComStation, and ArcaOS (and probably more). It is not a defect in ArcaOS, and is in fact due to a number of limitations in DOS itself (which can’t normally see disks larger than 2GB, anyway).
The workaround is to install a small TSR in your AUTOEXEC.BAT which limits the amount of free space exposed to DOS to 2GB. The file is 2GBFIX.COM, and is available from the excellent Hobbes file repository:
https://hobbes.nmsu.edu/?search=2gbfix
Download the file, unzip, and read the very simple directions in the included 2GBFIX.TXT.
While you’re downloading that file from Hobbes, be sure to browse other great software available there, and consider donating. Hobbes is a true resource for any OS/2 user, and is completely free for all.
An alternative solution is to download and install the V2GB.SYS driver in CONFIG.SYS:
http://www.tavi.co.uk/os2pages/v2gb.html
The advantage of this solution is that it does not take up additional space in the VDM (Virtual DOS Machine).
Note that neither of these solutions is developed nor supported by Arca Noae. References here are for convenience, only. Unintended side-effects may occur with the use of either of these suggested workarounds (e.g., in the case of V2GB.SYS, running “dir” in a DOS session while this driver is active will close the session once the command completes). Be certain to disable any workarounds for this before opening a trouble ticket for the DOS subsystem itself.
In a word, no.
Software and drivers included with ArcaOS and not distributed separately (either freely available from Arca Noae or provided as part of a non-ArcaOS subscription) are not licensed for use on, supported when installed on, nor have they been tested on other operating systems. In short, once you break the terms of the ArcaOS licensing agreement, you are on your own.
An excellent example of this is Arca Noae SNAP included with ArcaOS. This is not a free upgrade to SciTech SNAP/se installed with eComStation, nor is it an upgrade for SciTech SNAP Professional. While Arca Noae SNAP as included with ArcaOS has been updated, it has only been tested with ArcaOS, and is only licensed for use with ArcaOS. Installing Arca Noae SNAP from the ArcaOS installation media on any non-ArcaOS system is a direct violation of the ArcaOS licensing agreement, and Arca Noae will not provide any technical support for such installations, even when the ArcaOS license itself was legally obtained and when the ArcaOS license is not in use (ArcaOS itself has not been installed).
Arca Noae engineers are monitoring the responses by hardware manufacturers and other operating system vendors. The current status of our analysis and official policy statement is reported in this blog post (which will be updated as necessary).
Additional information and links regarding these security concerns may be found in that post, as well.
If you elect not to renew your OS/2 & eCS Drivers & Software subscription, the following changes occur in your account:
- The order details, accessed through your customer portal, will no longer have downloads available. Any updates or additional components released in this manner will no longer be accessible.
- Subscription-only content available from the Arca Noae subscription repository will no longer be accessible (your credentials will no longer work to authenticate).
- Access to the Mantis bug tracker to open new issues, report on existing issues, or as a knowledgebase of reference material will no longer be available.
As mentioned elsewhere in this FAQ, a subscription is not an entitlement. When it expires, all privileges associated with it expire.
In general, yes.
ArcaOS ships with the Base, Net, and Win Runtime packages to support various components included with the operating system (including the enhanced File Open Container). You should feel safe updating these whenever we post an update (we test these for regressions on ArcaOS). While the WPS Runtime does not ship with ArcaOS, it may optionally be installed to provide its functionality.
ArcaOS 5.0.1 shipped with the following eCo Runtime versions:
- Base – 2017-03-20
- Win – 2017-03-20
- Net – 2016-05-06
Visit our eCo Software Runtimes download page to check for updated packages.
Arca Noae continues to work to add wireless network adapter support to ArcaOS in the form of additional MultiMac drivers for some of these devices. However, in the interim, there is a workaround.
Wireless ethernet bridge devices are compact, generally inexpensive (under $50) units, which connect to the wired ethernet port on the computer and then wirelessly associate with an existing access point. These devices are produced by several manufacturers including Asus and IOGEAR, and generally, these are powered via USB. Often, they support a wide range of networking protocols and configure easily, using nothing more than a web browser. In addition, because they are external devices, installation is easy, and they can be positioned to obtain optimal signal without having to reposition the computer.
While Arca Noae does not recommend any one device over another, and cannot provide specific support for the configuration of these units, we can provide support for ArcaOS and its related configuration necessary to connect to one of these devices.
Yes. If you had a valid OS/2 and eCS Drivers & Software subscription at the time you purchased ArcaOS or an ArcaOS Support & Maintenance subscription, you may request a prorated credit of the remaining value of your subscription. This assumes that you will no longer be needing updates to any components included in the OS/2 and eCS Drivers & Software subscription for non-ArcaOS systems, as content in the ArcaOS Support & Maintenance subscription is not licensed for installation or use on OS/2 Warp 4, MCP/ACP, MCP2/ACP2, or eComStation systems. Of course, any software which you installed prior to trading up your subscription will continue to function, and you are still licensed to use it under the terms included with your original subscription.
Be aware also that the metering for the personal editions of the ArcaOS Support & Maintenance subscription and the OS/2 and eCS Drivers & Software subscription differs. The ArcaOS Support & Maintenance subscription personal edition is licensed only for a single system, whereas the content included in the OS/2 and eCS Drivers & Software subscription, with the exception of the ACPI driver, USB drivers, and Panorama graphics driver, may be installed on an unlimited number of systems (the ACPI driver, USB drivers, and Panorama graphics driver may only be used on a maximum of 5 systems).
See the relevant FAQ items for more details concerning license metering.
