This chapter shows how to include the DISK I/O package an eCos configuration and how to configure it once installed.
The DISK I/O subsystem is contained in a single eCos package, CYGPKG_IO_DISK. However, it depends on the services of the following other packages for complete functionality:
Device IO package. Disk devices operate within the generic device infrastructure.
The error package. Disk devices need to return standard error codes when operations fail.
The DISK I/O package can be added to any configuration just by adding its package during configuration. However, it is usually added as part of a group which also includes a filesystem implementation and hardware device drivers.
