, such as Read_track, where POPs and push directives were used, so it was set up to load the SETUP.S module at the back of the Bootsec.s; get the drive parameters, this should be a value floppy , mainly obtains the number of sectors per track, outputs "Loading system ..." in the screen, then loads the system module that is the kernel module, determines the root file system device, jumps between segments, and executes in the SETUP.S; Here is my understanding of some of the code in BOOTSEC.S. Bo

. The 8086 CPU has a total of 14 registers and is all 16 bits.That is, a total of 14 ax,bx,cx,dx,sp,bp,si,di,ip,flag,cs,ds,ss,es .These 14 registers are divided into general registers, control registers and segment registers in a certain way. Universal Registers:AX,BX,CX,DX is called a data register:AX (ACCUMULATOR): Cumulative register, also known as accumulator;BX (Base): Base address register;

Problem: Computes the number in the ffff:0006 unit multiplied by 3, and the result is stored in the DX. Answer: One: Analysis of ideas: 1. Whether the result of the operation will exceed the range that DX can store. The book in the ffff:0006 unit is a byte-type data, 8-bit, which ranges between 0 and 2 of eight parties, and the maximum is 2 of 8, or 255. Then the value after multiplying it with 3 is 255X3=765=02FDH. And the maximum value that DX can store is 2 of 16 square, namely 65535=0FFFFH,

shifted to the right. If it can be moved down, recursively moves down. If the target is reached, the recursion is terminated. It should be noted that it is natural to use recursion to express the Backtracking Method. Because the Backtracking Method takes precedence over depth, so does recursion. The program source code is as follows: # Include "stdlib. H"# Include "stdio. H"Static int path [30] = {0};/* indicates the record path. If the value is 1, it indicates the right. If the value is 2, it
