The Int 15/ax=e820h is used to get the memory-mapped address descriptor in the system, which is used by the operating system to get the memory size.
PS: Memory (Memory) can be what we normally call the memory on the motherboard, we call it base Memory, or it can be an edgeBase Memory memory that is extended as normal memory.
First, take a look at the relevant data structures:

In Ax #, the old SSRS reports for AX was stored in the AOT node "reportLibraries". We can find it all in the view 'application Explorer' of Visual Studio, but we can ' t modify it as usual.

Grub Source Analysis-1
This chapter begins the analysis of Grub's source code, version 2.02.
When the system starts, the BIOS loads the first sector of the hard drive (assuming boot from the hard disk) into the memory 0x7c00 location, which corresponds to the start function in grub (assuming grub boot), as shown below.

Installing and using Grub
To begin to explore the subtleties of GRUB, you first need to download, compile, and install it. But don't be afraid--it's not going to change your boot record--we're just going to compile and install grub, just like any other program, where we can create a grub boot disk. Please don't worry;
