B. The IDS has nine LRU's that will accept software installation (three EIUs and six IDUs). These LRU's must be independently loaded. A selector switch on the software date loader selects which LRU is loaded.
C. All the IDS LRUs use the same diskette. The diskette must be put back in the disk drive after the selector switch is moved. You move the selector switch when you install software into a different LRU.
D. You only install software into the LRUs that must have new software. It is not necessary to install software into the other LRUs.
E. The IDU LRUs and the selector switch positions are:
(1)
First officer's inboard display unit (ND-F/O)
