Hardware and Driver Development

The Hardware Developers Kit (HDK) documentation set includes manual pages, reference articles, and supporting information for customers who are developing device drivers or file system architectures to run on SVR5 systems (OpenServer 6, UnixWare 7.1.4 and earlier SVR5 systems), or to run on SCO OpenServer 5 Release 5.0.6 and 5.0.7 systems. Note that the driver interfaces as well as the files and utilities used to install, configure, and package drivers are included in the main operating system releases; the HDK does not need to be installed on a system to access these.
