Easy implementation while sérial farewell ATA IDE. In practice we must be careful when plugging the power supply connector hold the card below it tends to bend ... nice new generation graphical BIOS. Four USB-3 yes but only two ports on the rear panel and a socket on the map to add two with a small rack q'Asus could have included in the box (star less) ... is the LE version can -being. Small detail, in the Bios ATA sérial is set not in default AHCI (Advanced Host Controller Interface) and intall XP obviously it crashed because he does not see the disks. Win XP has no driver for this mode so to IDE mode in the BIOS. Seven and Vista have I think. The AHCI allows the disconnection hot and a gain in speed of 10 to 20% with recent disks see Doc. Other curiositée after XP intalled it did not detect the recorder / CD / DVD player (a plextor). After research, I found that the OS detected the drive when he had a disc inside. Diskless XP does not detect the start and over a very long easy 50s. With a disk in the drive that is folded in 20s ... solved two problems at once! First time I encounter this problem, it would come from the management of the Ata sérial or reader?.
