A/B slots describe a function that’s present on some Qualcomm Snapdragon 835 devices and most 845 and 855 devices. It’s used on Android for seamless updates and it uses two sets of partitions referred to as slots. This feature can often be “misused” for dualbooting purposes where you use one of the slots for your Android boot.img and the other one for a Renegade Project UEFI EDK2 bootloader.
NOTE: If your device is a Xiaomi or Poco device then it might not be a A/B device.
