SCO has begun shipping its version of UnixWare for Intel's forthcoming 64-bit Merced processor to selected SCO OEMs and ISVs. UnixWare for Merced Build Level 2 (BL2) is a full 64-bit UnixWare kernel and utility set, and features the IA-64 dynamic library linking. The OS ships with a full SDK, which can be hosted on IA-64 or current 32-bit environments. Full 64-bit addressing is supported, allowing UnixWare BL2 to access over 1TB of RAM and up to 8EB (1024GB) of disk space. The company has also announced a new software architecture that will allow 32-bit applications to run in the IA-64 environment. ISVs can simply recompile current 32-bit software without the need to change the structure of their applications. According to SCO, it will "allow ISVs to ensure the developments on IA-32 are fully upward compatible [with] Merced". &ref; click for more stories
