Seeking old driver PCI\VEN_8086&DEV_27C1&SUBSYS_10851734&REV_01

[Tony28N]

Hi,
This hardware ID is failing during refurbishment of an old cnc machine (I know a little about cnc, nothing about old hardware) and I'm not confident to wade through the dumpster fire of malware sites to find this driver.
Can anyone point to it?

That's the SATA controller in the ICH7R/DH and NM10 chipsets. The driver that supports this device is built into Windows, but optimal configuration information needs to be provided for this driver. This information is supplied via a Windows .INF file, which is included in the Chipset Device Software (a.k.a. INF Update) package. While there was a general release of this package released by Intel, you usually get this package through the motherboard/system manufacturer, as they may customize it to include changes to this configuration predicated by their design and/or to add support for other devices on their motherboard.

Now, you say this device is failing. Failing how? Do you simply mean not resolved? You also didn't mention what O/S version you are using.

I agree that, in general, you shouldn't be looking for this driver at any of the driver sites; they, in general, can't be trusted to not include malware. Unfortunately, because of the age of these products, Intel is not providing these packages on their download site. If you cannot fin done at the site for your motherboard/system manufacturer, you are going to have to look at these driver sites.

I found packages here: https://www.drvhub.net/devices/controllers/intel/ich7r-dh-sata-ahci-controller-dev-27c1. They appear to be clean but the proof is in the pudding. To simplify things, I have attached the extracted parts that would have come from Intel. You can install by right-clicking on the .INF file and choosing Install.

Hope this helps,

Thanks Scott,
I will give this a try and report back.
I appreciate your description - this is all new to me, so every scrap of information is a revelation. Its a Fujitsu/Siemens Motherboard W26361-W1571-Z2-02-36 W26361-W1571-X-02. The original motherboard was physically damaged, and was replaced with an identical item. On (Win XP) reboot and entry to the cnc controller application, a failure was reported in the initialization communication with the machine drives. This occurred with both original and fresh installation of the cnc application, hinting that the failure was on the mb side.
As I do things backward, checking device manager showed a driver failure for the PCIe device, and this supports my hunch that the motherboard was not able to communicate with the cnc side of the machine.
Please forgive my lay-speak. As noted, I know how to do cnc machining - how computers operate is dark magic.
Cheers

Hi Scott,
The driver allowed the device manager list to pass, but the initialization fault remains "Timeout 1:0 Init Object Handling Axis0.1 Wait for valid" - so the failure lies on the cnc side.
I appreciate the help you gave - One more little step is corrected.
Cheers

Tony

PS: I'm working with Power Automation PA8000 software and SDI Drives in the cnc machine, just in case you're a machining ninja as well....

Sadly, I'm not. Me brudder, who lives 2700 miles away, knows a lot about this stuff, but distance (ok, and old age) disallows absorption. I haven't even figured out 3D printers, and he says they're easy.
