I downloaded PRxxxx_20240415_db21e5f7d_Arabian-unofficial_24.5.0-trunk_Transpeed-8k618-t_bookworm_edge_6.7.12_xfce_desktop.tar. xz 2024-04-17 14:51 964M. I used Rufus to write to SD.When turned on, the Arabian download started. When the desktop appeared, I ran arm bin-config and installed arabian in the internal memory. I deleted the SD card on reboot. The system booted from the internal memory. WI-FI and BT are not working. Everything else works very fast.
