⇝ 5/Dec ➤ Managed to download latest Raspi OS 64bit version [2021-10]. Runs ok in RPi4.
⇝ 8/Nov ➤ Got rid of Fyde OS, can't be used because trial period over. Installed Ubuntu MATE 20.04 (Focal Fossa) 64 bit. This version is year 2020, but has LTS. Ooops! Forgot that Google don't have ARM based Chrome browser support.
⇝ 30/July ➤ RPi-400, noticed the built-in BlueTooth won't turn on with Raspbian (NOOBS & PINN). No problem with RPi-4. Probably an OS bug (forum checked). Waiting for a fix from Rasbian. (2) BerryBoot Raspbian version's bluetooth is working. (3) Zoom with RPi-400. Using a webcam. Zoom video lags and video from my webcam not working.
⇝ 12/July ➤ (a) 3.5" LCD tried to do dual HDMI-GPIO FBTFT display. Couldn't get it to work. The IC chip for this is ILI9486, but could not get XORG to work dual-screen. (b) Tested 3.5" LCD on RPi0-WH, it's working. The USB HAT pin headers is slightly fat, difficult to insert & cannnot fully go in. (c) Copied BerryBoot PiZero from Samsung Evo to Samsung Pro Endurance microSDcard using Balena Etcher.
⇝ 25/June ➤ 3.5" LCD display (RM61) kinda expensive. Worked via GPIO pins. But if LCD display, HDMI is disable & vice-versa. Found online several people made it display on both. Need to study their code & method more before trying.
⇝ 16/June ➤ DOSbian can install Win3.11! Problem display not full screen. After making change to SVN.config, can display more, but poorer resolution. Maybe better to run DOSbox in Raspbian.

⇝ 14/June ➤ Installed BerryBoot for Pi0 in Samsung 32GB EVO. Various OS installed.
