CONFIG.SYS PSD Statements

PSD stands for "Platform Specific Driver". These drivers provide an abstraction layer for the underlying hardware by allowing the operating system to call generic functions to perform platform-specific operations without worrying about the actual hardware implementation.

If multiple PSD statements are encountered, OS/2 will load each PSD in the order listed in CONFIG.SYS, and call the PSD's install function. The first PSD which successfully installs will be the one OS/2 uses.

PSD statements are processed before BASEDEV, IFS, and DEVICE statements.
