preseed instructions

Using PXE to install a Linux system is the most basic task in system integration and is also the easiest to ignore. Usually, once the system is installed, it is seldom ignored. There are already many PXE integration tools, such as cobbler. However, we still use DHCP + TFTP + HTTP to install the Linux system to reduce the investment time. PXE Server is configured based on Ubuntu12.04-server-amd64, CentOS system uses kickstart Using PXE to install a Linux system is the most basic task in system in

Preface:In the previous section we learned the interaction between the instruction and the controller by adding an action to the instruction and invoking the method in the controller. In this section we learn how the instructions and instructions between the interaction, we through a small game to learn with everyone, listening to the desert teacher said this is a foreign person to write the demo, we can le

Iv. conclusion of the experimentTask one: Using debug, the following program segment is written to memory, executed on a per-execution, observing the contents of the relevant registers in the CPU after each program executionMethod One:(1) Use the e command at the beginning of the 1000:0 to read the program's machine code into the memory unit, using the D command to view the information in memory, and using the U command disassembly, the machine code read to the assembly

Experimental tasks(1)1. Write instructions to memory using the a command in the form of assembly instructionsExecute the Write command with the T command2. Write the machine code with the e commandThe result of execution is the same as the a command(2)Write instructions to a memory unit from 2000:0Ax=1, using 8 times jmp to figure out 2 of the 8-time Square(3)The ROM on the motherboard of the PC is written

Experimental resultsGo to DOS, run debugUse the R command to view and change the contents of the CPU register.Modify the contents of the register AX with the R commandModify the contents of CS and IP with the r commandUse the D command to view the contents of memory 1000:0See what's at 1000:9List the contents of the Debug preset addressView the contents of the 1000:0~1000:9 unitView content in the same physical address with three different segment addresses and offset addressesModify the content

The MOV instruction is a dual-operand instruction and cannot be fully memory-operated in two operandsFormat: MOV dst,srcPerform action: DST Note:1. The destination number can be a universal register, a memory unit, and a segment register (but not a CS segment register).2. Immediate number cannot send segment register directly3. Does not allow data to be transmitted directly to two storage units4. No direct transfer of information between two segment registers is allowedAssembly Language Learning

Chrony software instructions for use, chrony instructions for use1.1.1 chrony Introduction Chrony is an open-source free software that can keep the system clock synchronized with the clock server (NTP) and keep the time accurate. It consists of two programs: chronyd and chronyc. Chronyd is a daemon running in the background. It is used to adjust the system clock running in the kernel and synchronize the clo

Powerful linux IDE-Geany configuration instructions, linuxgeany configuration instructions I started using Ubuntu today (mainly to prevent myself from playing games on windows) at the beginning, I was not used to finding a suitable Compiler (when can DEV c ++ come out of Linux?). codelite code :: blocks won't be configured. I don't know much about the tutorials on the Internet, so I started to study Geany.

Default Configuration:1> allow anonymous users and local users to log on.Anonymous_enable = YESLocal_enable = YES2> the logon name used by anonymous users is ftp or anonymous, and the password is blank. anonymous Users cannot leave the anonymous user's home directory/var/ftp, and can only download but cannot upload.3> the login name of

the memory and locate the production date as 01/01/92. (2) run the e command to modify the date and run the D command to check whether the modification failed. 4. Fill in data to the unit in which the memory starts from b8100h. Change the entered data and address, and find that a pattern is controlled by two memory units. The former controls the style and the latter controls the color. Experiment summary and experience ?No result is returned when the CPU writes data to the memory address c0
