This section summarizes requirements for device drivers for PC Card.
20. No user intervention required for correctly installing devices
| Required |
The user must not be required to perform any action other than to insert disks that contain drivers and other files.
21. Device functional immediately without restarting the system
| Required |
The user must not have to restart the system to be able to begin using the device, either after installation is complete or whenever the device is inserted in the system.
22. ZV-compatible PC Card driver uses DirectDraw Live Video Extensions
| Required |
ZV-compatible PC Card drivers must use software interfaces based on 32-bit DirectDraw Live Video Extensions (LVE) to configure the graphics controller to receive video input using the ZV Port. This includes programming the graphics controller to configure the format of the video data, its location on screen, and so on. LVE is part of DirectX 3.0.
ZV card device drivers must handle dynamic graphics state changes, such as resolution changes, color depth changes, and switching to and from full-screen MS-DOS – based applications.
