In our last post concerning GPT in ArcaOS, we discussed the first phase of support and how our specification allows for multiple partitions up to 2TB in size. As every GUID (Globally Unique Identifier) partition type requires a GUID, we have set:

90B6FF38-B98F-4358-A21F-48F35B4A8AD3

as the GUID for OS/2 Type 1 partitions.

Any GPT partition using this GUID should ultimately be recognizable by any GPT-aware operating system as belonging to ArcaOS.

Although this is now just a simple proclamation, it is, in point of fact, a major advancement for the platform, and sets the stage for our initial GPT support, currently planned for release with ArcaOS 5.1 in 2021.

Arca Noae makes no guaranty as to availability of GPT support for ArcaOS 5.1. When available, GPT support will be an ArcaOS feature only, with no plans to make the technology available for other OS/2 distributions.

Don’t have ArcaOS yet? Now is a great time to pick up a license or two and replace those aging Warp 4 or eComStation installations and get to know what’s new and improved. If you’ve never run OS/2 before, you’ll be amazed. If you last used OS/2 in the 1990’s, you’ll be even more amazed. ArcaOS runs the vast majority of existing OS/2 Warp 4 software, because it really is OS/2 – just better. ArcaOS supports more modern hardware than any other OS/2 distribution available today, making hardware upgrades much easier than ever before. An ArcaOS 5.0 license now means steep discounts on future upgrades, including 5.1.
