I have a problem either doing a clean(custom install) or upgrade of Windows 7 on a Vista SP2 machine. I get the message:
It appears from searching Microsoft's forums that the problem is no support for my RAID controller even if the most current driver is installed as described in this thread:
My PC is a 5 and a half year old Dell Dimension XPS Gen2 (Dell mother board Model 0U2424) and Intel chipset i875P with a 82801ER SATA RAID controller and a Dell Bios version A03. It has a 3.2Ghz P-4 CPU and 4Gigs of RAM and performs VERY well for a machine this old.
Is there any hope of finding or ever seeing drivers from Intel or any other source that would allow me to install Windows 7 on this machine?
When I run the Windows 7 Upgrade Advisor at http://windows.microsoft.com/upgradeadvisor it says "Not Compatible" and "The driver installed for this device is not compatible with Windows 7."
In Windows Vista Ultimate - Device Manager, under Storage Controllers -> Intel(R) 82801ER SATA RAID Controller -> Driver the version number listed is 184.108.40.2065 dated 10/12/2005. This probably explains the message above.
This chipset is also known as the Intel ICH5R (R = RAID) which appears (IMHO) to be supported under Windows 7 using the 220.127.116.113 drivers dated 7/17/2009. The page for the Intel Series 5 driver download is http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Chipsets&ProductLine=Desktop+Chipsets&ProductProduct=Intel%c2%ae+5+Series+Chipset When I installed Windows Vista Ultimate, I had to use the Intel 32-bit Floppy Configuration Utility with F6 during Windows Setup in order to have my RAID 0 disk recognized.
I would try the following (apart from the solution on the Microsoft link you posted):
I should be able to try Option 1 and post back.
When I look at the Intel 82801ER SATA RAID Controller Driver info in the control panel, I see:
version 18.104.22.16868 dated 6/17/2003 with "Microsoft Windows Hardware Compatability" as the digital signer and Intel as the provider.
The Windows 7 Upgrade Advisor reports Status "unknown" for this device and "We don't have compatibility information about this device."
I would certainly like to hear the result of your experiments, and LOVE to hear that you had success.
Please report back.
Thanks for the interesting reply. I had lost hope.
Unfortunately, I don't think I have good news for you. After my post, I tried updating my driver in Windows Vista Ultimate with the 22.214.171.1243 version from Intel's site...Device Manager says "The best driver software for your device is already installed." Needless to say, Windows Update doesn't do anything either...so I decided to do some more digging.
I downloaded a bunch of the versions from http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Chipsets&ProductLine=Chipset+Software&ProductProduct=Intel%c2%ae+Matrix+Storage+Manager After looking at the drivers from versions 126.96.36.1995, 188.8.131.521, 184.108.40.2060 and 220.127.116.113 (there are others too) I noticed the following:
The iaAHCI.* files support the newer ICH* chipsets. The relevant ICH5R driver files are:
iaStor.cat = signed Windows GUI driver catalog
iaStor.inf = text file describing registry entries, PCI vendor IDs, etc.
iaStor.sys = driver
TXTSETUP.OEM = text file for Windows DOS/Setup installer
Starting from 18.104.22.1681, the iaStor.sys driver shrinks from 854KB to 245KB and the driver supports just ICH6* and ICH7* chipsets (compared TXTSETUP.OEM wiith 22.214.171.1243 version). My guess is, even if you were to mix and match the versions (violating the license agreement), the iaStor.sys file would not support ICH5R.
Somewhere in the back of my mind, I also remember seeing a ReadMe that indicated that 126.96.36.1995 would be the last version to support the ICH5R chipset.
Perhaps someone with more skill directly related to Windows drivers might have an alternative...or maybe Intel/Microsoft will give in and support the older ICH5R on Windows 7.
I was afraid you would not have good news.
I did a little more digging, too. I found this discouraging info:
I have no idea if any of these discontinued boards use the chipset/RAID controller we are concerned with, but it certainly looks like Intel is not in the mood to work on older stuff.
Can you say "Planned Obsolescence"?!
I wonder if it applies to the servers using this chipset as well? I discovered that the Dell PowerEdge SC1420 (Adaptec CERC SATA1.5/6ch) and the HP ProLiant ML150 G5 (HP Embedded G5 SATA RAID Controller) also uses the ICH5R 82801ER chipset (or some variant); which leads me to wonder if (the Windows 7 -based) Windows Server 2008 R2 would install...or if the server OS is also left in the cold.
At any rate, I was able to find (one of?) the listing(s) for which drivers support which chipsets - http://www.intel.com/support/chipsets/imst/sb/CS-020826.htm
Thanks for the new info, but it's too late.
I gave up and installed Windows 7 on another disk drive I already had in my PC - a Barracuda that was used for video editing, but is now not really needed for that. I was then able to turn off the RAID configuration and format the two drives that had been my primary drive under RAID 0. So, I have not lost the use of any hardware....just a different configuration.
Windows 7 is quite impressive, and I am a happy camper....sort of.
Thanks again for you efforts.
Yes - I had to use the options in the Windows 7 setup/install procedure to point to the IDE drive and do a clean install to it, and fiddle around with the BIOS settings to point to it as the primary drive to get it to boot windows from there. Then I was able to get Windows 7 to recognize the two ex-RAID drives, format them, and use them (actually as my G and H drives since I had partitioned the IDE drive into C,D,E,F). I also had to use the tricks that are out there on the web to get the clean install of Windows 7 (from my Upgrade) to be activated. Use google to find them. There are several ways to do it, and one of them will probably work.
This is a little late but I was able to get RAID to work on my Dell XPS Dimension Gen 2. The drivers are not Windows 7 drivers, but they work. I downloaded the '32-bit Floppy Configuration Utility for Intel® Matrix Storage Manager version 188.8.131.525' from the Intel site, located here:
After creating the floppy disk, I set up a RAID0 array using CTRL-I at boot time (since I installed two new drives) and booted from the Win 7 DVD. It looked like the install was going to hang as it sat on the Win 7 dove wallpaper for a few minutes with just a mouse pointer, but it eventually got going. When the installation started, it informed me it could not find the driver for the RAID controller and prompted to search for one. I put in the floppy and it showed one SATA RAID controller in the list. However, it showed the wrong one so I unchecked the box that limits the display to showing what Win 7 thinks is compatible. With the full list of controllers displayed, I picked the 82801ER and off it went, nice clean install with no problems.
FWIW, I have the latest BIOS installed (A06).
Hope this helps anyone still looking to put Win 7 on their XPS Dimension Gen 2 with RAID enabled. It's worth it.
Installed Windows 7 recently.
The motherboard is an Abit IS7 with 82801ER RAID controller.
Followed dlewisfl' instructions - downloaded the drivers that he linked to.
Booted with my Windows 7 DVD - and after loading the RAID drivers - was able to see all my previous partitions under XP.
Deleted my boot partition but wasn't able to install Windows 7
Rebooted - and booted the Windows 7 DVD once again - chose the correct RAID driver - and now I was able to install Windows 7 on my previous XP partition.
Everything works - and I am a happy camper ;-)
Definitely worth it - give it a try! (if you are worried about your current partitions/files - backup is probably a good way to go - better safe than sorry )
