Solve the USB controller caused Ghost to start slow

Recently found that a new batch of machines to network gram suddenly found that the boot speed of this batch of machines is particularly slow, it takes nearly 1 minute to enter the ghost menu, it is obvious that the motherboard or Said to be caused by the chipset, because the same ghost file is normal on the other motherboard's machine.

by the method in the BIOS to disable one by one to exclude devices can cause the problem, the exclusion of a floppy disk controller, IDE controller after still no effect, helpless against the BIOS daze, over and over again turned the BIOS There may be options related to this problem, when I am about to find out why the BIOS interface is blue, I suddenly see the option I have never thought of, USB!

disable usb controller restart, GHOST less than 3 seconds to enter the menu. That's right, it's a problem with the usb controller!

however, pleased too early, this time I maintain the two bars at the same time with this board machine nearly 400 units, each closed usb controller that is a terrible thing. So I guess there should be parameters ghost usb device does not detect, he looked GHOST parameters on Baidu, GOOGLE, finally I found it, it is "-nousb"
