characteristics of the address [1]. Therefore, its 4-bit low address should be blocked. It should be noted that the memory address is the physical address of the system. When Windows is running in protection mode, it must be converted to a linear address to directly read and write the memory space. Articles about this conversion method are common and will not be described here. The above program provides a

configuration. Devices may have an on-board Rom ining executable code for x86 or PA-RISC processors, an Open Firmware driver, or an EFI Driver. these are typically necessary for devices used during system startup, before device drivers are loaded by the operating system. In addition there are PCI latency timers that

The I/O space is a 64 kB addressing space. I/O addressing is not divided into real mode and protection mode, and the addressing mode is the same in various modes. In Windows NT, the system does not allow ring3 user programs and user-mode drivers to directly use the I/O

1. The bus is composed of an electrical interface and a programming interface. Kernel functions used to access peripherals of Peripheral Component Interconnect (PCI, peripheral device interconnection,Because PCI bus is widely used on desktops and peripherals on larger computers today, and bus is the best supported bus

There is a problem with the "SM bus controller" and "other PCI bridge devices" Driver in the Device Manager, smpci After WinXP reinstalls the system, there is a yellow question mark in the Device Manager, which is "SM bus controller" and "other PCI bridge devices". The mothe

PCI is a widely used bus standard, it provides many superior to other bus standards (such as EISA) new features, has become the most widely used in computer systems, and the most common bus standards. Linux kernel can better support PCI bus, this paper based on the Intel 386 architecture, discusses the development of PCI devi
