I've got two NICs in a Server, bge0 &amp;&nbsp;bge1. I only want one UP at a time; that was bge0 but has now been changed to bge1. Problem is that when the Server is rebooted, bge0 is UP, not bge1. Have to bring it up manually with ifconfig. How can I get it to default to bge1?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
