How to Fix the "PCI 60806A Aa9lrv.1" Driver Error If you’ve recently opened your Device Manager only to find a stubborn yellow exclamation mark next to a device labeled PCI 60806A or Aa9lrv.1, you aren’t alone. This specific hardware ID is commonly associated with older PCI Serial or Parallel port expansion cards—the kind used to connect legacy printers or industrial equipment to modern computers.

  1. Manufacturer's Website: Visit the official website of the device manufacturer and search for drivers specific to your device model.
  2. Driver Update Software: Utilize reputable driver update software that can scan your system and provide updated drivers.
  3. Windows Update: Windows operating systems often provide driver updates through Windows Update.

Step 1: Identify Your Chipset (DO NOT SKIP)

This is crucial. Download a free tool called Unknown Device Identifier or open Device Manager → Right-click the unknown device → Properties → Details → Hardware Ids. Look for:

Windows Registry Editor Version 5.00
[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\4d36e96c-e325-11ce-bfc1-08002be10318]

✅ What to do instead

  1. Find the real device – Open Device Manager → right-click the unknown device → PropertiesDetails tab → Hardware Ids. Look for codes like VEN_XXXX&DEV_XXXX.
  2. Search that Hardware ID – Use those codes (e.g., VEN_8086&DEV_1234) in Google or on a trusted database like PCI Lookup or LaptopVideo2Go.
  3. Get drivers safely – From the actual chip manufacturer (Intel, Realtek, etc.), your PC/motherboard brand’s support page, or Windows Update.

Step 3: Extract the Driver (Do NOT run an installer)

Most likely, the download will be a .zip or .rar file. Extract it to a folder on your desktop (e.g., C:\Drivers\SAA7134).
