Asmedia Asm1083 Serial Port Driver Windows 10 ((full)) May 2026

This is a specific hardware request. Before providing a full report, it is important to clarify a critical technical correction:

The ASMedia ASM1083 is not a serial port controller. It is a PCIe to PCI bridge chip. It is commonly found on motherboards to allow legacy PCI slots to work on a modern PCI Express bus.

Because it is a bridge (not a COM port), Windows 10 typically uses its own native drivers (pci.sys) . You generally do not need to download a specific driver for the ASM1083 itself.

However, if you are looking for a driver because a physical 9-pin serial port (RS-232) on your PC is not working, that serial port is actually connected to a different chip (e.g., ITE, Fintek, or ASMedia’s actual serial chips like ASM1042). The ASM1083 is just the "adapter" for the PCI slot that contains that serial card.

Frequently Asked Questions (FAQ)

Q: Is the ASMedia ASM1083 a serial port controller? A: No. It is a PCIe to PCI bridge. Your actual serial port is another chip (e.g., Oxford, Winbond, or Fintek) connected behind this bridge. The ASM1083 simply allows that chip to talk to your modern motherboard.

Q: Does Windows 10 64-bit have native support? A: Partial. Windows 10 will install a generic "PCI-to-PCI bridge" driver, but it often fails to allocate resources correctly. You need the ASMedia-specific INF file.

Q: Can I use Windows 7 drivers on Windows 10? A: Yes, but only via the "Have Disk" method. Windows 10 will complain but generally accepts them.

Q: Will this work on Windows 11? A: Possibly, but Windows 11 has stricter driver requirements. Many users report the ASM1083 fails to install on Windows 11 entirely. Stick to Windows 10 for legacy hardware. This is a specific hardware request

Source 1: ASMedia Official (Rarely Updated)

ASMedia does not typically host consumer-facing downloads. Instead, they distribute drivers to motherboard manufacturers. The official driver version that works with Windows 10 is 1.16.5.1 or newer.

Part 1: What is the ASMedia ASM1083 Chip?

The ASMedia ASM1083 is a PCI Express to PCI bridge chip. Its primary job is to take a PCI Express lane (common on all modern motherboards) and translate it into a legacy PCI bus. This allows you to use old PCI expansion cards on a motherboard that only has PCIe slots.

Key technical specifications:

• Host Interface: PCI Express Base Specification 1.1 (x1 lane)
• Secondary Interface: PCI Bus Revision 2.3 (32-bit, up to 66 MHz)
• Function: Transparent bridge

Many motherboards from ASUS, Gigabyte, MSI, and others from the late 2000s to early 2010s integrate this chip. You will also find it on standalone PCIe-to-PCI adapter cards. Frequently Asked Questions (FAQ) Q: Is the ASMedia

Testing and verification

• Use a terminal program (PuTTY, Tera Term, RealTerm) to open the COM port and test basic send/receive.
• Loopback test: Short TX and RX on the port, send data in the terminal; if you receive it back, basic UART is operational.
• Use a serial protocol logger or oscilloscope if timing or signal integrity problems persist.

Part 5: Post-Installation Verification

After installation:

1. Reboot your PC.
2. Open Device Manager again.
3. Find the device under Ports (COM & LPT) or System Devices. It should show:
   • ASMedia ASM1083 Serial Port without any warning icon.
4. Right-click → Properties → Driver tab. Confirm driver version is 1.16.5.1 or newer.

If you have a PCI card plugged in (e.g., a sound card), it should now appear under Sound, video and game controllers.
