E-EQ-MX2RG-L-ARC MX2 Reference Guide
The purpose of the CONFIG.SAF file is to provide a minimal boot configuration that preserves
the flash and RAM drives. When the safe-boot sequence is initiated, the CONFIG.SAF file is
processed instead of the CONFIG.SYS file. This prevents chaining into the drive-C initialization
files by omitting the NEWFILE = C:\CONFIG.SYS command. It also eliminates the loading of
the DECODE.SYS and CFGDEV.SYS drivers.
