This method results in the CR800 retaining its settings (a feature since OS version 
16). The new OS file is temporarily stored in CR800 SRAM memory, which 
necessitates the following: 
•  Sufficient memory needs to be available. Before attempting to send the 
OS, you may need to delete other files in the CPU: and USR: drives, and 
you may need to remove the USR: drive altogether. Since OS 25, older 2 
MB CR800s do not have sufficient memory to perform this operation. 
•  SRAM will be cleared to make room, so program run options and data 
will be lost. If CR800 communications are controlled with the current 
program, first load a default.cr8 CRBasic program on to the CPU: drive. 
Default.cr8 will run by default after the CR800 compiles the new OS and 
clears the current run options.
