Ofcourse this doesn't include final configuration for disk partitions,floppy configuration parameters, or tape system setup. All of these actionsmust be performed by user code, either through <b><a href="./sysLib.html#sysScsiConfig">sysScsiConfig</a>( )</b>,the startup script, or by the application program.<p>The user may customize this code on a per BSP basis using the <b>SYS_SCSI_CONFIG</b>macro. If defined, then this routine will call the routine <b><a href="./sysLib.html#sysScsiConfig">sysScsiConfig</a>( )</b>.That routine is to be provided by the BSP, either in <b>sysLib.c</b> or <b>sysScsi.c</b>.If <b>SYS_SCSI_CONFIG</b> is not defined, then <b><a href="./sysLib.html#sysScsiConfig">sysScsiConfig</a>( )</b> will not be calledas part of this routine.<p>An example <b><a href="./sysLib.html#sysScsiConfig">sysScsiConfig</a>( )</b> routine can be found in <b>target/src/config/usrScsi.c</b>.The example code contains sample configurations for a hard disk, a floppydisk and a tape unit.<p></blockquote><h4>RETURNS</h4><blockquote><p>OK or ERROR.<p></blockquote><h4>SEE ALSO</h4><blockquote><p><b><a href="./usrScsi.html#top">usrScsi</a></b>, <i>VxWorks Programmer's Guide: I/O System, Local File Systems</i></body></html>⌨️ 快捷键说明
