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.
