Write the operating system-general Linux technology-Linux programming and kernel information by yourself. The following is a detailed description. I completed pmtest2.com according to the steps in the book. Are you sure there is no error? However, during debugging, The LABEL_GDT offset is found to be 103, Prepare for loading GDTR Xoreax, eax Movax, ds Shleax

input, then call the Listcmd function, which puts the previously generated cmd struct pointer in a new struct, as left, and the parsed part as right, so that it is parsed like a list in sequence Listcmd as follows The execution of the time, in turn from left to right. SummarizeAt the time of insignia, there were a few wordsI didn't quite understand it at first, and now I realize that from the shell design of XV6, we can see that the internal only uses a small number of common

the concurrency of modern computer systems is based on time slices, that is, in a very short time, each process is run separately. In this way, each process is running continuously on a macro level, and virtually every process runs intermittently. So the question is, what is the process?　Ii. what is a processThe purpose of the process is to control the concurrent execution of the program. Process entity consists of three parts: program segment, data segment and PCB. We know that the essence of

In the windows2000/xp/2003 version, the operating system provides shared functionality by default, which is implicitly shared by all, meaning implied, including all logical disks (c$,d$,e$ ...). and system directory Wimit or Windows (AdminS). This function is designed for the convenience of network management, but the function of the user has brought a lot of sec

entry area, the critical section, the exit area and the remaining area. The entry area requires code that indicates the request enters the critical section, and the exit area has code that represents the exit critical section.Critical area problem: There is time to enter, no space, etc., limited waiting. Within the operating system, execution of kernel code also encounters a critical section problem.When e

As a programmer must understand the knowledge of the operating system, and now self-taught exams and soft exams are required to test the operating system. Soft examinations is mainly the examination process and storage, so as long as the system of learning self-study test

In the afternoon to visit the user site, the feeling that the problem is really strange, and finally found that the computer is win 2000 of the operating system, feel the crux of the problem may be here, the internet Google, found that the original media Player 11 does not support the Win2000 system, Users are required to download the player version for the user'

the power button shutdown, nor directly with the reset button restart, which has a large impact on the system, especially the hard disk. The shutdown command is Halt, and the restart command is reboot. In fact, there are shutdown commands to complete similar functions, if necessary, please use the man command learned today . Finally finished this chapter, hope that the new person can be well read, this will help you. the configuration of Xwindow will

reflects the three points you "do not understand" things, I think you should see more.In addition, be polite, no one will treat you as a fool. There are a lot of people in a situation, by attacking others to reflect their own tall. In fact, really strong people, there is no need to do so.Like a review of Gentoo's Lord, be sure to say I'm attacking Gentoo, but in fact the commentary does every opportunity to show how much he understands Gentoo and how much he can use it. As for? The way you embo
