http://www.ibm.com/developerworks/cn/linux/l-linuxboot/In the early days, starting a computer meant feeding the computer a tape containing a bootloader, or manually loading the bootloader with the front panel address/data/control switch. Although the current computer is equipped with many tools to simplify the boot process, it does not necessarily simplify the process.Let's look at the Linux boot process fr

of the "business layer" and "Data layer" and "infrastructure", and of course the system runtime environment-related things.3.1. Application of contractual design in the service layer to resolve dynamic condition mismatch errors (exposing problems online through contractual design patterns)This design method is mainly to expose the dynamic runtime condition mismatch error to the automated regression test on line. Because contracts in the service layer may be at risk of being modified, we have no

designed to control the startup process (provided by starting the service) and provides an interface between the system firmware and the operating system (provided through the runtime Service). Unlike the BIOS, it has its own architecture, does not depend on the CPU, and it has its own device drivers. UEFI can mount partitions and read some file systems.When a UEFI-equipped x86 computer starts, UEFI will look for a system storage partition marked with a GUID (globally unique identifier) and mar

remaining segments are at the specified address. The dashed line indicates the processor's power-on execution process. Here you need to briefly explain the next PPC4XX series of processor features, the PPC4XX series processor is a large feature of the MMU is normally open, power on is turned on. After power-up, Ppc4xx has a shadow tlb that maps the top 4k of the address space to where it's mapped, depending on how the internal logic of the processor fills the TLB, and the address arbitration o

There are several different ways to boot virtual machines, each of which has its own advantages and disadvantages. 1. BIOS bootloader Suitable for full virtualization, loader simulates BIOS Original article: Booting via the BIOS is available for hypervisors supporting full virtualization. in this case the BIOS has a boot order priority (floppy, harddisk, CDROM, network) determining where to obtain/find the boot image.......

Four different methodsThere are four ways to install OpenWrt on a single device:1. Through the original firmwareOpen the Management page of the original firmware via your browser and install the OpenWrt firmware by using the "Firmware Upgrade" option. Get.Note: Some times the original firmware upgrade feature contains some verification features that determine that you did not swipe into the wrong firmware file, and if this feature exists, he will prevent you from installing openwrt in this way.2

I have always wanted to install my favorite Linux system through the network, always confused, yesterday spent a whole day to ponder the research, Kung Fu is not a conscientious, done! Highing (sister's, afraid to use the wrong word to check the next, Sister's dictionary also deceive) I will highing ^-^Afraid later forget, special remember to do this, nonsense less say, start it!First, the principle: first boot from the network boot, it needs to find a DHCP server from the network, the DHCP serv

Follow these steps to customize the WinCE6 and 0 operating systems for a new hardware device: 1. Create a Board-level Support Package (BSP) for a specific hardware device. The BSP must include the BOOTLOADER and OEM adaptation layers.Adaptation Layer (OAL) and some necessary drivers. 2. Use the created BSP to customize a system Design ). Create a Platform through VS2005Builder project. This project can compile and generate the final runtime Image file

The chip reads 1 kb of data from the CE1 space to the internal SRAM, and then runs from address 0. Generally, a program is much larger than 1 K bytes, so there is usually a second-level bootloader that is used to load the main program. After bootloader is run, c_int00 () is called to initialize the C runtime, such as the stack and static variables. Then, bios_init is called to run the main function, after t

system porting development. The Linux environment configuration, the gun toolchain, the test tools, and even the integrated development environment are a great tool to transplant Android systems.(3) familiar with the Linux kernel. It is important to be familiar with kernel configuration, compilation, and porting because Android porting development typically requires a new customization of the Linux kernel.(4) familiar with the target Board guide mode.
