I want to install a WD 7200 eide hard drive as a slave (2nd hard drive) on a asus p4p800 motherboard. The master hard drive is a seagate sata hard drive. My problem is the WD instructions only show you how to install a 2nd hard drive as if the first is also a eide hard drive. I see on the motherboard there are 2 sata plug in's. There is also a eide plug in so I believe it can be done. Im not the best at this stuff but it something to do why the hurricane is going on. Any instruction would be great. If i dont answer Ive lost power. the storm is coming Thanks

I had the same problem with my system and it took me a while before I figured it was really simple to fix. I don't know if you already took care of the problem, but just in case you didn't..... I had 4 devices working through 2 EIDE ports including my WD hard drive and then a Seagate HD through primary on SATA. The problem was, whenever I would have the jumpers set correctly it would boot up and say Error running OS. What you need to do is go into your BIOS setup at bootup (mine was entered by alt+f2 or tab then delete) and going to advanced BIOS settings. Under the settings adjust the device to be SCSI instead of the HDD-0 or whatever that probably is in its place. This will then boot up your windows off your original hard drive while still allowing you access to your new hard drive and all other devices. Hope this helped.

Wow.. I dont know what you guys are doing wrong.. but I run sata and ide devices. Sata run on their own little cables... they dont need jumpers.. as far as I know. I havnt had any problems. My ide harddrive is on its own cable and it registers just fine. I dont understand why you are labeling a sata as a slave/master. That is sort of the point... as far as I know... that sata just are.. they are not slave or master on a cable. anyways.. not that that helps any..

Oh, just as a tip, i dont thin you have to touch the jumpers on the satas. Just put your ide as master. and you are good to go!

I too am having the same problem. My OS is on my SATA hard drive and when I plug in my EIDE maxtor 160 GB HD the system trys to boot from it. I do not have the option in the BIOS to boot from SCSI device, as mentioned.
The EIDE maxtor I have has been set to slave (jumperless in this case).

Oh, and ASUS forums are down indefinitely. (lovely) Any help would be great!

Well I figured out my own problem!
I had to go into the BIOS and set the boot order causee when I put the EIDE HD in, it automatically changed the boot order. Their was also a section under the boot config in the BIOS where I could place the HD's in some proirity, like 1st, 2nd or 3rd. I also had to change this. The OS now loads from the SATA HD and the EIDE HD was assigned a new drive letter on it's own and everything is functional.
However, and this is a big however...... The PC takes about 5 times longer to reboot and stays at the ASUS splash screen about a minute longer than when it did before when I just had the SATA HD plugged in.
This is really disturbing, if anyone can help that would be great.
