sata ramdisk

This is my three articles on how to use SATA hard disk settings published in the PC newspaper. I saw some people in the report saying that they had sorted the articles and posted them on the forum for convenience, so they sent them here. Hope you can help your friends who encounter problems. Q A on SATA hard drive (PC Report: 04-33) bigh As the prices of SATA ha

During installation, you can only turn off SATA for installation. If the traditional method is difficult to install the operating system, you must not only seize the opportunity to press the "F6" key to load the stat driver, make a floppy disk with a driv

What is RAMDisk, I'm afraid I don't need to say that we all know. As for the advantages of RAMDisk, Baidu you can see because Ramsik has a fast read and write speed so "temporary files can speed up", "Install software can be opened seconds" and so on various optimization methods, more sharp speech also think that using RAMDisk can prolong the life time, protect t

The following two articles are very good articles on the RAMDisk file system in the ARM9 forumToday did a test, let Linux2.6.29.4 from the RAMDisk root file system to start a successful, summed up.It involves more content, a lot of things no longer detailed, for further study please consult the relevant information (Baidu or Google a lot).Development environment: Fedora 9Cross-compilation toolchain: ARM-LIN

1. ramdisk is the smallest Linux rootfs system. It contains all Linux systems except the kernelTools required for import and management include the following directories: Bin, Dev, etc, home, Lib, MNT, Proc, sbin, USR, VAR. Some basic tools are also required: Sh, ls, CP, MV ...... (In the/bin directory); necessary configuration filesPieces: inittab, RC, fstab ......

Introduction in Linux, there is a special feature-initializing the memory disk initrd (initial RAM disk) technology, and the kernel supports compressed file system images. With these two features, we can enable Linux to initialize memory disks from an early stage. Introduction In Linux, there is a special feature-initializing the memory disk initrd (initial RamDisk) technology, and the kernel supports compressed file system images. With these two fun

modify the following two configuration items:A): General setup --> select initial Ram filesystem and RAM disk...B): device drivers --> Block devices --> select the ram block device support item. Check whether optimize for size is selected. If not, optimize the kernel size and configure it as needed.Modify (8192) the default RAM disk size Kbytes option(4096) default RAM disk size KbytesThe reason for the modification is that the ramdisk I created late

The steps are as follows:1. Unzip the kernel source treeExtracting the linux-2.6.29-mini2440-20090708.tgz into your working directory will generate a friendly arm of the kernel source directory linux-2.6.29 that has been modified and has several mini2440 default profiles. Specific steps refer to the friendly arm mini2440 Development Board User manual, specifically not detailed.2. Modify Kernel configuration optionsEnter the kernel source directory linux-2.6.29 directory#cp config_mini2440_t35. c

1. What is ramdisk? Ram: memory, Disk: disk, which can be used as a partition in Linux. It is called ramdisk. For exampleFiles that are frequently accessed and not changed can be stored in the memory through ramdisk, which can significantly improve system performance. Ramdisk works in Virtual File System (VFS)Layer, c

These days the reference to the country embedded experimental manuals and online information to complete the U-boot customization, core customization, RAMDisk root file system production, and success. Strike, summarize. This article refers to a lot of articles on the Internet, it is not noted. Thanks to the help of the heroes, if there is similar, hope forgive me.Development environment: Red Hat Enterprise Edition 5Cross-compilation Toolchain: arm-lin

Today, Kingston's 1g memory stick is ready. In addition to the original 1.5 m memory, a total of GB memory is allocated, and MB is used as the virtual hard disk. The swap files, temporary system files, and temporary webpage files are all placed on it. It's really cool. It's faster to open files and browse the Internet, especially for memory-consuming software such as Photoshop, which is less likely to read hard disks. Previously used in this document Google Earth always has a very bad feeling, a

OverviewYou need to use INITRAMFS in your recent work. Initramfs is a RAM FS that enables Linux systems to be started in stages. There are two main ways to use Initramfs: one is to compile the minimum file system directly into the kernel image, the other is to make the RAMDisk, then load the RAMDisk into memory and assign it to the kernel. Either way, the kernel-driven support is required, so using INITRAMF

The U-boot customization, kernel customization, and ramdisk root file system have been completed by referring to the China-embedded lab manual and online materials. Let's sum up. I have referenced many articles on the Internet, so I will not mention them one by one. Thank you for your help.
