System: -Microsoft Windows XP -Media Center Edition 2005 -Service Pack 3 Computer: (I initially started with an “HP Media Center m1050y” machine in 2004, but I’ve since upgraded the motherboard to one made by Foxconn as described below.) -Intel Pentium(R) 4 CPU -3.2 GHz, 1.00 GB of RAM HDD: -Samsung Serial ATA -Model: HD501LJ -500GB/7200rpm/16M Graphics Card: -ATI ALL-IN-WONDER X600 PRO Series Motherboard: (If googling, just copy the following “Foxconn Socket 775 6627MA-RS2H Motherboard” or “Foxconn 6627MA-RS2H Motherboard” for best results.) -Foxconn N15235 -6627MA-2.0-RS2H • SiS 662 + 966L • Socket 775 • FSB 800/533MHz,OC to 1066MHz • PCIex16 • DDR2 667/533/400 • USB 2.0 • 6 Channel Audio • 10/100M Lan • RAID • Serial ATA Basically, I’m having a "Setup did not find any hard disk drives installed in your computer" problem during a clean reinstall of WinXP OS. Already tried the “slipstreaming” technique as well as using a floppy disk drive via F6 during boot up, both to no avail, still get the same error message. I also tried changing the RAID settings to IDE, and although it worked thereby allowing me to install my OS, it was at the cost of significant performance loss. My system is now reaaaaaaally slow compared to what it used to be before I did the WinXP reinstall with the IDE settings. For example, if I drag an application window around my desktop, I see a choppy tail trailing slowly behind it trying to catch up to the main window. Absolutely horrendous! Same thing goes for scrolling up and down pages in my browser or in a Word document, it just has that lag before it reacts to any input. Here are the specifics: I did a clean reinstall of Windows XP Media Center Edition 2005 Service Pack 3 using the following BIOS setting (it’s the last one in the sequence in quotes)( (see link to screenshots of my BIOS below)): Standard CMOS Features > Integrated Peripherals > OnChip IDE Device > SiS Serial ATA Mode > "4P(IDE)+2S(IDE)". The other two options available to choose from this menu are, "4P(IDE)+2S(RAID)" and "4P(IDE)+2S(AHCI)". Which of the three options should I use? Shouldn’t it be the "4P(IDE)+2S(RAID)" setting for best performance since I am using a SATA drive? I heard that SATA drives set to "4P(IDE)+2S(IDE)” mode in the BIOS (my current BIOS settings) suffer a significant performance loss as a result, therefore you should stay away from that setting if dealing with SATA drives. I’ve already spent days and went through 4 or 5 DVD-R’s trying to “slipstream” Foxconn RAID drivers, Chipset drivers, as well as other Foxconn drivers onto the Windows XP Media Center Edition 2005 Service Pack 3 installation CD using nLite(to slipstream) and PowerISO(to burn the bootable ISO DVD-R), only to encounter the "Setup did not find any hard disk drives installed in your computer" error all over again. Like I mentioned earlier, I can bypass the error if I change the Standard CMOS Features > Integrated Peripherals > OnChip IDE Device > SiS Serial ATA Mode settings to option "4P(IDE)+2S(IDE)", which I did do. But obviously I don’t like the severe performance loss I am experiencing as a result. So here’s the big question! Is the "4P(IDE)+2S(IDE)" setting I am currently using fine, or should I switch it to "4P(IDE)+2S(RAID)"? If the answer is yes, then how should I deal with the “Setup didn’t find any hard disk drives etc, etc.” error? Any ideas? Did I slipstream my disks wrong? Or use the wrong drivers? Btw, I followed the slipstreaming instructions on this page, http://www.howtogeek.com/howto/wind...d-disk-drives-during-windows-xp-installation/ . I realize this issue has been dealt with in these forums before; the difference being they had it on a different system with different BIOS settings, plus I’m coming into this just having changed my RAID “mirror” dual hard drive setup back to a single drive setup (if that makes any difference). I also wasn’t able to resolve this issue following any of the advice given to the people who have posted before in regards to this problem. So, I figured I needed to start a new thread. Thanks for reading. Looking forward to your feedback and hopefully some relief. -Dominik Downloaded the drivers I used for slipstreaming from here. 1.)http://www.foxconnchannel.com/support/downloads.aspx And here: 2.)http://support.dell.com/support/dow...tid=&impid=&formatcnt=1&libid=0&fileid=136025 Link to screenshots of my computers BIOS. 1.)http://viewmorepics.myspace.com/ind...viewPicture&friendID=75594228&albumId=2645700 Important Note: Previous to my recent reinstall of the OS I had a 2 hard drive RAID setup (“mirror/RAID 1” if I remember correctly, although it might have been a "RAID 0/data striping" setup, I can't recall for certain) with a 500GB Samsung SATA drive and a 250GB Western Digital SATA drive. I know, I know! Different brands, different sizes, not the best idea in the world, but it worked for over one year for me that way. But anyways, before my reinstall I changed things back to a normal non-RAID one hard drive setup using only the 500GB Samsung drive. Could “jumper” settings be the problem here? Or not since ”jumper” settings only apply to IDE drives?
