AI Technical Summary

Problems solved by technology

IDE hard drives cannot meet the requirements of high-performance computing in terms of speed
Moreover, the mainstream hard disk type on the market is SATA hard disk, and the use of IDE hard disk will cause market limitations.
The way of connecting the SATA hard disk through the IDE to SATA interface improves the speed of the hard disk, but increases the cost of the product and the complexity of the software design.

Embodiment Construction

[0016] The following specific embodiments illustrate the method of the present invention.

[0017] The hardware platform based on this example is Loongson blade server. The main part of the Godson blade is the Godson 3A chip and the AMD 780E+SB700 chipset. The main function of the PMON program is to realize the initialization of each device function on the Loongson blade, to ensure the normal operation of the Loongson blade, and to guide the operating system smoothly.

[0018] Such as figure 1 The structural block diagram of the South Bridge SB700 is shown. The work of PMON on the South Bridge device can be roughly divided into three parts: 1. Device enabling; 2. Device scanning and configuration; 3. Device initialization. Aiming at the characteristics of PMON, the initialization work of the SATA controller in the present invention is also divided into three parts. figure 2 Shown is the connection method of the SATA hard disk on the Godson blade.

[0019] 1. Before the P...

Abstract

The invention aims to provide an initialization method of an SATA (Serial Advanced Technology Attachment) controller in a PMON (Process Monitor), which can be used for initializing the SATA controller in a Southbridge and realizing the normal work of an SATA hard disc. According to the invention, the normal identification of a Southbridge SATA controller can be firstly assured and the SATA controller can be accurately initialized by the PMON in an equipment initialization process, thereby realizing the accurate initialization and guide of the SATA hard disc.

Description

technical field [0001] The invention provides a method for realizing the BIOS of the South Bridge SATA controller, in particular a method for realizing the BIOS of the South Bridge SATA controller based on the Loongson CPU platform. Background technique [0002] Loongson (English: Loongson) is a general-purpose CPU independently developed by the Institute of Computing Technology, Chinese Academy of Sciences. It uses a simple instruction set, similar to the MIPS instruction set; the basic input and output system it uses is a software called PMON. PMON is an open source software with some functions of BIOS and boot loader. It is mainly used in MIPS, ARM, PowerPC and other platforms, which is different from the BIOS of X86 architecture. [0003] Loongson products currently on the market have used two types of hard disks, namely IDE hard disks and hard disks connected through the IDE to SATA interface. IDE hard drives cannot meet the requirements of high-performance computing i...
