ArcaOS is not just a repackaged, re-branded OS/2 Warp distribution. ArcaOS has undergone significant enhancements to address long-outstanding issues with prior OS/2 distributions, as well as to ensure its compatibility with the widest range of modern hardware available. Many portions of the OS have been completely rewritten to more fully leverage the power and performance of modern PCs. This isn’t your grandfather’s OS/2.

ArcaOS runs…

…OS/2 applications (32-bit and 16-bit)
…16-bit Windows applications
…DOS applications
…ported Linux applications
…select 32-bit Windows applications
…Java applications
…Qt applications
…REXX applications
…much more…

Yes, everything that you were able to run under IBM’s OS/2 installs and runs on ArcaOS.

Do you have a custom written OS/2 application? Favorite, classic OS/2 productivity, word processing, spreadsheet, or graphics applications? OS/2, Windows 3.1, or DOS games? ArcaOS runs all of those just like OS/2 Warp 4, only better. ArcaOS is more compatible with modern hardware, makes more efficient use of memory and system resources, and installs more easily than any other OS/2 distribution…ever. Really.

Do you have a system with 16GB of RAM in it? Want your apps to really fly? Configure ArcaOS to utilize all memory above 4GB as a RAM disk, and at bootup, copy your most frequently used applications there. It’s like running your OS/2, Windows, DOS, REXX, Java, and ported Linux applications on air.
