FYI
T10 System Version: 7.1_111 with the option MirrorFileServer=yes will not work at the moment.
Also if you look at System Tools it will not show the Mirror File Server tab. A beta version 7.1_116 did not resolved these issues.
Correct. Even latest beta is not fixing this.
Looks like a problem with the non-existing flash memory.
T10 saves the firmware in the BIOS chip.
But EnableCachedIni=yes works.
