Purpose

Load release16 code to the ICU.

Steps to run

Deliveries

Loads

All commanding is via Malindi or USN except where specified to the right of the command.
First check the checksums in a terminal window (shell) not ITOS! This should be done before CVS version control as a cvs commit will slightly change some of the files and change the md5sums. 
cd loads
md5sum -c MD5SUMS
You should see OK for each file which is there.
  1. start icu_enable_pt
  2. start icu_idle -- only if currently observing an AT
  3. load at_config_eeprom_0e3100_v16patch1.img -- these are all short and quick
  4. load at_config_eeprom_0e3100_v16patch2.img
  5. start icu_enable_at_pt
  6. load standard_eeprom_0fff80_v16patch1.img
  7. start icrc_tables_r(0x391) -- report ANY errors
  8. return -- near end of commanding window
  9. load Spacecraft RTSs 61-63 if not done already - for this release just 61
