First of all sorry for my ugly english=)
Now i’m using ZeroShell, it has ability to boot from CD and load recently saved profile from USB flash drive, after that i can unplug USB drive. All settings data is stored to RAM disk. I can update profile (on USB Flash) on demand.
It is necessary for me, that all settings data has disappeared after unpluging power cord.
Can i implement same functionality at Microtik RouterOS?
