Graphics Driver Description

For the Display Manager to load and install a driver, the run-time requirements should be set to kDriverIsOpenedUponLoad and kDriverIsUnderExpertControl. The device name is used as the name for installation in the unit table. Graphics drivers should report kServiceCategoryNdrvDriver as the OS run-time service category and kNdrvTypeIsVideo as the type within the category.

A typical driver description structure for a PCI graphics card driver is shown in Listing 8-1.
