The IDE is an electronic integrated drive, which is meant to be a hard drive that integrates the hard disk controller with the disk body. Xiao Bian is really stumped when it comes to helping a friend solve the slow start of Windows XP. The use of optimization master, Super Magic Rabbit and other tools, modify the registry, have tried to start a slow, starting the progress bar brush more than 20 laps. By the author with the exclusion of the hardware has no problem (NF2 motherboard -8rda+, cpuxp2500+, memory 2x256mb, graphics ATI9550, hard disk 120GB), the system is Windows XP integrated sp1,dx9.0b, Motherboard driver is nForce4.24, graphics driver is Catalyst 4.8, none of the problems found. When I open Device Manager and look at the problem with the IDE device, it is likely that the startup slow start is caused by detecting the IDE device (Figure 1). Disable the port in the IDE Channel 4 ports without receiving the device directly (Figure 2). That is, tell Windows XP that I don't have IDE devices on some of the ports and don't waste time checking. Here's the trick: if one of your ports doesn't connect to the IDE device, change the "Automatic detection" to "none". After a reasonable set of IDE channel, start the progress bar Brush 3 laps went in, the problem was solved satisfactorily.
