Part 5: BIOS settings BiOS (Basic Input/Output System) is installed on the motherboard Flash ROMProgramIt acts as a communication between the hardware and the operating system. Through the bios, you can set the operating mode and parameters of the hardware. When the system is turned on, the BIOS will first perform the boot self-test (post ). Press the key to go

role of cmos ram is to save the hardware configurations of the system and set certain parameters for users.Because the power consumption of cmos ram is extremely low, the backup battery on the cmos ram * motherboard can be powered off after the system power is off. Therefore, the user setting parameters stored in the CMOS will not be lost. Cmos ram is only a storage chip and only supports data storage. Special Programs are required for parameter sett
7.2 hardware prefetch of data
Pentium M, Intel Core solo, Intel Core Duo processors, and Intel Core micro-architecture-based intel netburst processors provide hardware data prefetch mechanisms, this mechanism monitors the application data access mode and automatically fetches data. This action is automatic and does not require programmer intervention.
For intel netburst-based processors, the features of the

The SSD is read and write data cache, is the virtual machine data io first fell to the Ssd,esxi host background to synchronize the data on the SSD to the mechanical hard disk.The ESXI hosts in the cluster need to enable Vsan functionality, and the
through specific software. Next, let's take a look at the router's LAN and WAN connection ports.1. LAN interfaceAccording to the interface name, we can see that these interfaces are mainly used to connect routers and LAN, because the LAN type is also diverse, therefore, the LAN interface type of the router may be diverse. Different networks have different interface types. Common Ethernet interfaces include AUI, BNC and RJ-45 interfaces, as well as FD

requirements.Android HAL Architecture. The rationale is to use the library (. so file) in the Android system to invoke Linux drivers located in kernel space (typically accessed through device files). The android application (apk file) can then access the library in the HAL through the NDK program, or access the library in the HAL directly from the Android application. The new version adds the entry code for the HAL schema that is required by the HAL architecture.Added HAL for LED driver.

Especially for the masses who are familiar with m$ products, installing sap is simply a torment, this is why I want to write this series of essays, because the installation process of a software is usually very technical, and many step by step installation instructions can be found on the Internet, however, if you want to learn more about "why" by installing sap, rather than simply knowing "How to do it" on the Internet, you should be able to gain some benefits from this.

In a system, interruption is a very important component. With interruption, the system can improve system efficiency without having to keep polling (polling) for events, in addition, interrupt control is usually distributed in various places, and different parts are controlled by different functional programs, so that the system can work norm
