Click Here --->>>

After replacing the motherboard in a Gateway system with a new motherboard,I needed to update the driver used for Norton Ghost 7.5 backups. The system was running Windows XP Professional.The Windows Device Manager identifies the NICbuilt into the motherboard as a "Realtek RTL8139 Family PCI Fast EthernetNIC"I downloaded the NDIS2 driver for DOS (Support MSclient,Lantastic,Lanman, Norton Ghost) for the RTL8139 NIC.I extracted the contents of the RTSND2.327_EXE39/EXE/NDIS2DOS directory within the zip file to a directory on the Ghost server's hard drive.If needed, you can download a zip file with the contents of just the NDIS2 directory needed for Ghost below or you can download the entire zip file provided by Realtek.

If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter Realtek RTL8139/810X Family Fast Ethernet NIC into the search box above and then submit. In the results, choose the best match for your PC and operating system.

Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.

Recommendation: Novice Windows users are recommended to use a driver update utility like DriverDoc [Download DriverDoc - Product by Solvusoft] to assist in updating Freetech Ethernet Adapter device drivers. DriverDoc takes away all of the hassle and headaches of updating your RTL8139 Family PCI Fast Ethernet NIC drivers by downloading and updating them automatically.

Realtek RTL8139 Family PCI Fast Ethernet NIC errors can be rooted in an outdated or corrupted device driver. When the operating system that your device depends on gets an update, drivers can suddenly stop working with it. Don't worry, because these PC problems will probably be fixed after updating your Ethernet Adapter drivers.

Finding the correct Ethernet Adapter driver directly on the manufacturer's website for your hardware might seem futile. Although you might have plenty of experience in handling Realtek RTL8139 Family PCI Fast Ethernet NIC drivers, there still is a lot of time involved in this update process. Using defective or non-functional drivers will cause more damage and errors on your machine.

For the time and effort involved in the driver update process, we highly suggest using driver utility software. Driver update utilities ensure you have correct drivers that are compatible with your hardware, it also guarantees that there is a backup of current drivers before any software/hardware changes are made. Sustaining a driver backup file is an excellent feature that allows you to revert any driver back to a previous version, in the event that something catastrophic occurs.

Gave it a shot in my old Vostro200 running High Sierra and Mojave. Installed the old IONetworkingFamily fat-binary kext from and the card still works under macOS! First drivers for this card were released for OS X 10.1/10.2!

This post will explain all I know about developing a driver for the Realtek rtl8139 network adapter. It is a network interface card that is capable of 10 / 100 Mbit/s network speeds. It is emulated by qemu which makes it a prime target for learning about driver development.

The rtl8139 is connected to the PCI bus. With PCI, every device is identified by a pair of IDs. The pair consists of a vendor ID and a device ID. The rtl8139 has a vendor ID of 0x10ec and a device ID of 0x8139. You can check any pair of vendor ID and device ID on or

First, you have to check if the system has the rtl8139 build into it (or if qemu does emulate the card) by listing all the PCI devices of the system and searching for the vendor and device ID. PCI device listing is described here.

One of these function in one of the devices on one of the busses will be the RTL 8139 but it is not predefined which one it is. That means the tuple of (bus, device, function) is unknown and the driver has to find the device.

The data to send is written into a buffer (byte array) in operating system memory. Then the buffer is transferred over to the card via DMA (which is why the driver enables bus mastering). You have to specify the physical address for DMA! The PCI card does not understand paging! It only reads from memory at physical locations and does no go through the memory management unit.

In the context of setting up a virtual machine, e1000 emulates an Intel NIC, rtl8139 emulates a Realtek NIC, and virtio is a para-virtualized driver, i.e. it "knows" it's operating in a VM and basically just passes the network traffic between the VM and the host in the most straightforward way possible.

If you are running a legacy operating system within the VM, you may need to choose the virtual NIC according to what NICs are supported in the legacy OS. Intel e1000 has drivers available for even pretty old & obscure OSs. But the hardware of the physical e1000 NIC is pretty complex, so there will be some overhead because of the need to emulate it.

Rtl8139.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the operating system, hardware etc.The free file information forum can help you determine if rtl8139.sys is a Windows system file or if it belongs to an application that you can trust.

The process known as Realtek RTL8139 NDIS (version 5.0 Driver) or NDIS 5.0 driver belongs to software Realtek RTL8139(A/B/C)-based PCI Fast Ethernet Adapter NT Driver or NT-Treiber für Realtek RTL8139(A/B/C)-basierten PCI-Fast Ethernetadapter by Realtek Semiconductor (

Description: The original rtl8139.sys is an important part of Windows and rarely causes problems. Rtl8139.sys is located in the C:\Windows\System32\drivers folder.Known file sizes on Windows 10/8/7/XP are 20,992 bytes (90% of all occurrences) or 23,070 bytes. The driver can be started or stopped from Services in the Control Panel or by other programs.The file is a Windows core system file. The program has no visible window. The service has no detailed description. It is a trustworthy file from Microsoft.rtl8139.sys appears to be a compressed file.Therefore the technical security rating is 4% dangerous, however you should also read the user reviews.

Important: Some malware disguises itself as rtl8139.sys, particularly when not located in the C:\Windows\System32\drivers folder. Therefore, you should check the rtl8139.sys process on your PC to see if it is a threat. We recommend Security Task Manager for verifying your computer's security. This was one of the Top Download Picks of The Washington Post and PC World.
