intervention, backups will be scheduled during periods of low OPS LAN activity. If
necessary, the File Server may be removed from the OPS LAN to shorten the time
needed to perform the backup. The contents of the following directories on the OPS
LAN File Server are earmarked for automatic backup:
• D:\Admin (OPS LAN administration files)
• D:\HomeDir (Crew’s home directory)
• D:\Share (Shared data directory)
• D:\OOCI\ARM (OSTPV data files)
• D:\OOCI\MPV\Data (MPV data files)
• The Windows NT Registry
Ground personnel are capable of updating the backup scheme, as needed.
4.18 Software Updates
SSC software loads can be updated by 3 methods: Autoloader, Late Update Disk, and
Real Time Update.
4.18.1 Autoloader
Autoloader utilizes a bootable program floppy disk and a COTS software Ghost
load image on CD or PC Card Hard Drive to quickly reload an SSC laptop’s hard
drive to a baselined disk image. If necessary, laptop CMOS settings are reset during
this process. Because the contents of the laptop’s hard drive are overwritten,
personal data must be saved or backed up prior to running Autoloader.
For commonality and crew convenience, the S-POCCB encourages the owners of
payload-unique laptops to supply a software reload/restore CD that can be accessed
by Autoloader. SSC engineers can assist with the creation of a disk image CD.
4.18.2 Late Update Disk
For simple load updates during a Shuttle rendezvous, load updates are made with a
PC hard card, which contains a batch file. The PC hard card is inserted in the
laptop’s PCMCIA slot, then a unique desktop icon is clicked. The batch file is
initiated, making the necessary changes to the laptop’s load.
4.18.3 Real Time Update
For data files (i.e., the IMS database) and for off-nominal fixes, changes are uplinked
to the ECS/OCA laptop in real time. From ECS/OCA, the new files are transferred
by the OCA operator to targeted SSC laptops. If a file must be executed to perform a
software update, uplinked files are written to a portable medium (PC Flash Card,
PC Card Hard Drive, etc.). A crewmember will be directed to take the medium to
targeted laptops and execute the appropriate batch file. Uplinked fixes to software
will be tracked on the ground and included in subsequent scheduled updates during
