First ,update your eeprom！See rex`s Guide
After you combine Adopter and NVMe expension card(JUST CM5***CM4 cannot shutdown(AXP228 still works!!,if its hardware problem we wont fix this problem,we will take our attention to service CM5 better,just wait!!)***)
About the config.txt：you need change the line “dtparam=pciex1=on“
You have at least three easy way to boot your system on NVMe system!
FIRST WAY
boot on SD card (most people can do this ,someone cant boot on NVMe`s adopter,see SECOND way&THIRD way),use SD card copier just wait!，then take off the sd card ,boot on nvme!
SECOND WAY
If you cannt boot on SD card !just get a nvme card reader,all the thing likes TF card but faster.
THIRD WAY
SD card copy to USB3.0 **USB flash drive，**then plug Flash ,use SD card copier copy to NVMe!
ABOUT battery-AIO &new battery system!,just wait!!
