Block Driver Catalog Items and Sysgen Variables (Compact 7)
3/12/2014
In Windows Embedded Compact 7, you can support one or more of the block device drivers available in the catalog, or you can implement your own block driver to support a specialized block storage device.
For more information, see Block Drivers.
For more information about how to add or remove catalog items, see Design Your First OS.
Hardware and Software Requirements
