UEFI support in ArcaOS 5.1

Development and testing of Arca Noae's support for UEFI continues. Here's a brief recap of how this will work in ArcaOS 5.1:

When the installation media boots, if the system is determined to be in UEFI mode" as opposed to Legacy mode" (Legacy" here refers to the configuration which presents a traditional PC BIOS), ArcaOS will begin the preboot process using its compatibility system. Essentially, this is a 64-bit environment which will provide a rather complete BIOS emulation for the ArcaOS kernel, including VGA services for video display.

I often wonder just how hard it must be for the ArcaOS developers to work within the confines of OS/2 and what must be stringent licensing agreements and NDAs with IBM. This kind of low-level programming on OS/2 can't be easy.
