Windows XP, in addition to the appearance and security of the interface can be greatly improved, in many small places considered very thoughtful, considerate and convenient for users. For example, it stores the current state to the hard disk, and then the boot does not have to go through the hardware initialization, directly from the storage state to read data, generally able to boot in about 15 seconds, the speed of start-up greatly improved. However, due to hardware and software compatibility,
Q: After backup in the recovery system, the NIC number becomes eth1 instead of eth0A: Modify the Udev rules file, delete the 70-persistent-net.rules file under the/ETC/UDEV/RULE.D directory, and then restartFor some special applications, such as a USB stick Linux system, after deleting the file, you can create a folder with the same name in the directory mkdir 70-persistent-net.rules so that no Udev rule file will be generated after each boot.Q: Set multiple IP addresses for a single NICA: You n
that you choose some of the 2012 production of motherboards, in order to better install solid-state drives. But if the 2.5-inch SSD is the same size as the traditional hard drive, then can be directly installed in the traditional solid-state hard disk positions can, because very simple, here is not detailed, as long as the solid state hard disk installed in the host hard disk positions, and then use screws fixed, and then connect the hard disk data line and power cord can be, the following figu

This option is set to "Enable" by default, set to "Disable", and then rerun Ghost for problem resolution.
Tip: When combined mode is open, the BIOS can d
the data has several and parallel work, while the disk that holds the checksum data is only one, which brings the bottleneck of verifying data storage. RAID 5 works by slicing the data from each disk into chunks and storing them in each disk that makes up the array, thus easing the bottleneck when validating data is stored, but dividing the data and controlling the storage costs at a speed.
Depending on the hard disk interface, RAID is divided into SCSI raid,ide raid and SATA raid. SCSI RAID i

A recent transplant of the lower u-boot-2014.10 to tq335x, if transplanted based on am335x EVM, does not require much change.
Because TI's am335x EVM development uses an EEPROM to save the onboard configuration information, which distinguishes the different board models, and tq335x does not have the EEPROM, therefore, it is necessary to modify the EEPROM related parts, so that the u-boot adapt to the tq335x Development Board.

At present, the method of installing the system is relatively simple and quick, nothing more than a U disk PE boot, manual ghost, until the familiar blue-gray interface appears, the next assumption by the progress bar rolling, is a matter of minutes, but there are users to reflect the 500G hard disk, cache 16M computer Ghost speed only 150M What is this for?
This phenomenon does have a lot of users have encountered, ghost speed of thousands of trillion per minute is very common, ghost speed is

Compared with the original naming method, this new way is longer, difficult to remember, but the advantage is that the number is unique, when the system migration is

AGP is configured in many places like PCI, so many video card bios can also be placed in the motherboard BIOS. That's why we never saw the bootrom on the onboard NIC.8 .
