, mapping to physical memory always starts with the lowest address (0x00000000). For kernel space, the address map is a very simple linear mapping, 0xc0000000 is the physical address and linear address between the amount of displacement, in the Linux code is called Page_offset. Let's take a look at the description and definition of address mappings in kernel space in include/asm/i386/page.h:/** This handles the memory map.

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB?
Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese character requires two bytes of storage space,
1. What is LVMLVM is a logical volume management tool that has two versions, LVM1 and LVM2. Native support in 2.4 kernal and 2.6kernal respectively.LVM provides management capabilities for higher logical levels of disk partitioning. The storage volumes can be re-partitioned and moved through LVM.LVM can name a logical volume custom named development, sales, etc., instead of "SDA" "SDB"2.

The motherboard does not light maintenance methods:
Example 1. A pci1600-f motherboard is not lit. First of all, visual inspection, found that the Power control IC U24 (AIC1569) surface has burned traces, welding U24, check the peripheral circuit did not see abnormal. The board returned to normal after replacing the U24. According to the user reflects this problem is more common, AIC1569 purchase is more problematic, I found from the data can be used HIP6004 directly substitute it.
Example 2.
bootstrapper contains program code and error messages, error handling, and so on that check the partition table of the hard disk. When the hard disk is started, the master bootstrapper checks the bootstrap flag in the partition table. If a partition is a bootstrap partition, then there is a partition flag 80H, otherwise 00H.
The system stipulates that only one partition is a bootstrap partition, and if the partition table contains more than one bootstrap flag, the main bootstrapper will give a
official online 100 series of bios or stay in the old version, to find a new BIOS will have to go to Taiwan's official website to find. So want to taste the new CPU players must keep a mind, first look for a new BIOS to ensure that the support is good to start, or buy back on the machine that is embarrassing.
The current mainstream motherboard manufacturers, such as Asus, Hua Yin, MSI, and so on have to support the new CPU BIOS release, and small series also through the foreign exp
Introduction to the advantages of WIN8 system UEFI mode startup:
1, UEFI to provide a larger disk capacity
Traditional MBR partitions can support only 2.2TB hard disks and 4 primary partitions, and one of the UEFI specifications, GPT partitioning format, can support hundreds of terabytes of hard drives and 100 primary partitions, especially useful for users who use Win7.

only 2.2TB hard disks and 4 primary partitions, and one of the UEFI specifications, GPT partitioning format, can support hundreds of terabytes of hard drives and 100 primary partitions, especially useful for users who use Win7. On the other hand, in Asus, Gigabyte and Seagate, such as the efforts of manufacturers, 32-bit system + traditional MBR partition can be "virtual disk", such as the use of the form of more than 2TB hard drive, but that is cert

The first thing you need to remind users is that if you feel the hardware knowledge, especially the BIOS is slightly missing, or do not imitate the operation of this article, in the brush BIOS upgrade process to do the most possible not to make mistakes. Although most gigabyte and ASUS motherboards currently on the market have a way to automatically restore the BIOS, but the premise is that your BIOS has been backed up or downloaded from the official

to set up four-leaf grass on USB. Use the traditional mode of the simplest, most reliable (5,6,7 and 8 series standard default BIOS or UEFI set gigabyte motherboard). For all other UEFI based systems, such as ASUS 7 and 8 series motherboards, the EFI partition installed to USB in Uefi boot mode is UEFI boot only.
