This config.sys environment segment gets queried and cleared (pointer) by the EDR COMMAND.COM via the following function https://github.com/SvarDOS/edrdos/blob/8a173d3df14576cdfc4fcf501861b55f162c850e/command/cstart.asm#L2767-L2782 It seems to construct a new environment from the temporary config.sys environment and looks for keys pressed on boot (I guess to do single stepping etc.). https://github.com/SvarDOS/edrdos/blob/8a173d3df14576cdfc4fcf501861b55f162c850e/command/com.c#L1629-L1661 _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
