is from the left and the third number is disable if it is 1, and if zero, the break is enabled. 3. Turn off the power and reboot. 4. Press the break key on the terminal within 60 seconds of the router's startup. The rommongt; prompt is displayed. If the prompt is not the case, the terminal does not issue the correct interrupt signal to check whether the break key is correct or is set to disable. 5. At the prompt, enter o/r0x42 or o/r0x41,o/r0x42 meaning to boot from the flash memory, o/r0

1. // directory, also known as the root directory, is located at The top level of the Linux file system directory structure. The only partition in many systems. If there are other partitions, you must hang them somewhere in the / directory. The entire directory structure is tree-structured and therefore also known as a directory tree. 2. binThe bin directory is a command file directory, also known as a binary directory. Contains important Linux commands and binary (executable) files for syste

normal, This eliminates the seemingly defective hardware interface and is a failure to set the software parameter incorrectly. The network router register value is composed of four 16 binary digits, wherein the low 4 bits determine the startup mode of the system: when the minimum 4 digits are 0-0-0-0, the network router does not load the system mirroring, but enters the monitoring state (ROM Monitor mode) or maintenance state (Maintenance mode) requires manual booting, and when the minimum 4 bi

, because the CPU is waiting for the slow disk system to provide the data. WA is the ideal for 0. If WA is often greater than 10, the file system may require performance tuning. 2 Observation of CPU activity Vmstat is more reflective of CPU usage than top: US: The percentage of time that the user program uses the CPU. The larger the number, the busier the user process is. SY: The percentage of time the system calls use CPU. Note that NFS is running in the kernel, so the CPU time consumed by

The diskless network mainly refers to the workstation operating system, the application software and other files are stored in the server disk of a computer network configuration. There are no disk drives on the workstation (including floppy disks, hard disks, CD-ROMs). It is only superficial and does not have substance meaning. The system structure of computer network refers to the mutual relationship between network server and workstation wh

correct interrupt signal to check whether the break key is correct or is set to disable. 5. Enter o/r0x42 or o/r0x41,o/r0x42 at the prompt to boot from the flash memory, o/r0x41 meaning to boot from the ROMs (note that the first character is the letter O, not the number 0). Better use 0x42, In the case of flash memory is not installed or erase, only use 0x41, if there is 0x41 can only view or erase configuration, can not directly change the passwor

One. Concept of a full installation kit (distribution)Linux is actually a kernel (system call interface, thread, memory, file, device), a complete operating system should be composed of some software kits and Knernel,As a result, some companies load needed packages into Linux core programs and then release them as CD-ROMs for a small amount of service charge.

Program to lose weight three steps away For developers who design embedded Linux systems, there is a problem that must be taken into account, and that is the space of the memory.We know that embedded Linux systems use memory not floppy disks, hard disks, Zip disks, CD-ROMs, DVDs, these well-known large-capacity conventional memory, it uses such as ROM, Compactflash,m-systems diskonchip, Sony's MEMORYSTICK,IBM Microdrive and so on are very small, sim

NFS is a network file system that allows multiple machines to share a file resource that accesses a single host.NFS may be used in the following situations:1. Multiple PCs share printers, CD-ROMs, and other resources using the same PC.2, multiple clients to access the same network resources, to ensure that access to the same resource is not different.3, Web applications, if you need to access certain domain names to another server, you can configure t

they is fixed and standardized for PCs. The ability to boot from a CD-ROM came much later during the evolution of the PC, and as a result of the PC architects took t He opportunity to rethink the boot process slightly. As a result, the modern BIOS boots from a CD-ROM is a bit more complicated (and more powerful). CD-ROMs use a sector size of 2048 bytes instead of a., and the BIOS can load a much larger boot image from the disk into Memory (not

Specific methods: 1. Connect the iOS device to the computer with the data cable; 2. Open the itools, turn on the "Apps" tab, select the app on your device, find the Chick Simulator, and click "File Sharing"; 3. Open "Documents" → "myroms" folder in turn; 4, import. Take the PSP as an example, open the PSP folder, click the "Import" button above to select an ISO or CSO file, you can import the ROM into it. A few things to note: 1, PSP and NDS need to unzip the ISO, CSO or NDS file i
