What is BootLoader?
BootLoader is a small program that runs before the operating system kernel runs. Through this small program, we can initialize the hardware device and establish a memory space map to bring the system's hardware and software environment to a suitable state, in order to prepare the correct environment for the final call to the operating system kernel. In an embedded system, there is usually no firmware like a BIOS (note that some embedded CPUs also embed a short startup program), so the entire system's load-start task is completely done by the BootLoader. For example, in an embedded system based on the ARM7TDMI core, the system usually starts at address 0x00000000 on power-on or reset, and the BootLoader program is usually arranged at this address.

·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
