Possible future implementations

SCO is investigating ways to simplify the task of porting NT device drivers to SCO systems. Because SCO drivers have different entry points depending on their level in the kernel hierarchy, different implementations would be involved in supporting other types of NT drivers.

The implementations currently under consideration include:

• Provide an IRP emulation object with which the driver can interact. This could be coded in the driver entry-point function before the NT driver's entry point is called.

• Implement a dummy deferred procedure call interface that calls the driver's interrupt handler immediately.

• Provide the NT driver support functions. SCO systems already provide kernel functions or macros for most of the same functionality so this would be mostly a matter of coding NT function names to call the equivalent kernel function of macro.

For SCO OpenServer 5 Release 5, NT drivers must be rewritten before they can be configured into a SCO kernel.
