Intel 82566mm Nic Driver For Mac


I have HP Laptop i installed windows 8 and All my windows 7 drivers are working well on it except Intel 82566MM Network Card when i put my lan cable in it the system gone be mad alot of loss in packets and the device is laggy some times it gave me death screen i do all the trouble shooting for network and installed the update in compatibility mode for windows 7 nothing is worth it's driver problem as when i put the laptop battery mod to maximum performance some times it working well i do clean install and the same thing and tried to upgrade from windows 7 the same thing please suggest a working solution !!!!




Intel 82566mm Nic Driver For Mac



What is the driver version showing in Windows Device Manager? I am guessing you are using the version 9.13.41.1 driver that Microsoft provided as part of Windows 8. The next version of the Intel web packs that is coming out soon, probably within the next week or two. The new version, version 17.4, will automatically install the latest generic e1e Windows 7 driver for you on your Windows 8 system.


Installing the latest Windows 7 driver in Windows 8 might solve your issue, but with built in network connections you never know if a driver update will help. Do you know if HP supports Windows 8 on your laptop? If not, you might not get everything working properly under Windows 8. Even if HP does not support Windows 8, you might find it worthwhile to make sure you have the latest BIOS version. Sometimes those updates also have changes that affect the network connection.


yes i used the default windows 8 network driver i will install windows 8 again and check for the latest driver from here , i don't think HP Will Support My Device For Windows 8, So i Came Here To My Network Card Driver Manufacturer To Get Some Help


Meanwhile driver version 17.4 has been released. It installs fine on Windows 8 but does not solve the issue at all. Always when running in battery-mode the machine freezes a few seconds every 3-10 seconds and therefore is unusable.


Some Intel engineers did investigate this issue and this is what they found. When the system is in battery mode to save power, Windows 8 is doing something different compared to Windows 7 and earlier versions of Windows. For some reason the driver is not getting called by the OS in battery mode resulting in transmit hangs.


I do not anticipate any driver update for this issue, but you should be able to make a registry change to the interrupt type from MSI to legacy to work around the issue. After disabling MSI on a test machine here, the hang was no longer happening.


Thank you again for coming up with the solution. Although the underlying problem seems not to be resolved and many people might not find this information here on the board and still suffer from the issue as long as no driver update is officially released which fixes the problem.


and committing the change to the wim. Now WinPE4.0 boots and performs without pervasive temporary hangs. Curiosly (form me) the tampered inf in the driver store didn't stop the driver installation and loading.


By the way, the same workaround of disabling MSISupport succeded with the built-in ndis6.0 driver that came with Winpe4.0 (e1e6032.sys, nete1e32.inf, DriverVer=04/19/2011,9.13.41.1). In this case, just to be sure about the extension of tampering unchecking, I changed the inf file in three different locations. This may be innecessarily overscoped for our goal of influencing plug and play configuration but as i said, I wanted to evaluate the scope of inf checking).


Contact the manufacturer for the latest updates and technical support information. If you can no longer get driver support from your computer manufacturer, you can check this page for what OSs are supported with our generic Intel drivers: Supported Operating Systems for Intel Ethernet Controllers (LOM).


Attached is a new kext I created for the latest round of Intel E1000e wired network cards. This is primarily based on dingguijin's Intel82566MM kext. I got the latest Intel Linux driver code and put that into dingguijin's framework. This kext works well for me on my Dell Latitude E6410 which has a 82577LM card but should work with other new Intel network cards. Note that Intel branched the code a while back after the Intel82566MM which means that my new kext may not cover all the cards that the Intel82566MM kext does so this is not a supercede although it will overlap with some cards. See below for the list of cards that it should work with.


Now the caveats: I've compiled the kext to work with Leopard and Snow Leopard and for 32-bit Intel, 64-bit Intel, and for PPC. And I'm pleased to say that it was able to get a Gigabit connection. However, with only the one test computer, I've only been able to test it on 32-bit Intel and on Snow Leopard so let me know if there are problems with other versions or platforms. Also note, in particlar, that some of the theoretically supported cards are "special case" cards as defined by Intel (82571, 82572, 82573, 82574, 82583, and 80003ES2LAN) that use alternate driver logic that I was not able to test. And then there's the big caveat that this is my first kext so in addition to the usual disclaimers about not blaming me for anything going wrong, add in a novice rider!


I'm currently using dingguijin's 1.0.3 drivers, which load fine. I'm hoping to get yours going as I have an issue with dingguijin's where when put under stress (e.g. multiple scp file transfers at the same time) either the card will simply stop responding (it stays green in the network settings but no network traffic works) or it grinds all the apps doing network stuff and in turn my system to a halt.


i am running 10.6.3, and I have removed all other sources for ethernet drivers, the system don't have any ethernet controllers when i boot. (I use [url=" -why-insanelymac-does-not-support-tonymacx86/"]#####[/url] to rebuild caches and repair permissions)


I really enjoy reading your blogs. I'm very interested learning on this subject, particularly porting linux driver to OS X. It is not easy to learn about OS X driver development but your blog may help me to understand it better. Thank you for sharing the source code.


i don't know why but Intel considers the 82575 and 82576 to be special case drivers. You'll note that it's not in the list that Intel provided with the code I downloaded from intel.com. I searched intel.com and found this download for your driver, which says that it only works for 3 cards. (It is also interesting that it says it isn't the latest code even though if you search by product it is the only code that matches - clearly a glitch on the Intel site.) Since your driver isn't covered by the E1000e Intel code, that means it isn't covered by this kext.


Thanks for the driver and source. Is there any chance you might be able to bring over some of the stuff from the regular e1000 linux driver? This way older PCI cards, such as the 82541, would be supported. Thanks, again.


Sorry, imk, that's unlikely. The only sensible thing to do when porting Linux drivers is to keep the Apple version matching the original Intel version for Linux. The bulk of the Intel code doesn't change - the major changes for the Mac are just for the wrapper. So merging two sets of Intel code distributions would be a major challenge that it doesn't seem Intel would even want to take on. What you need is to port the E1000 code from Intel using the same tricks as dingguijin did originally. It's no small feat, and I say that based on experience.


The default behaviour of the driver previously assumed a staticInterruptThrottleRate value of 8000, providing a good fallback value forall traffic types, but lacking in small packet performance and latency.The hardware can handle many more small packets per second however, andfor this reason an adaptive interrupt moderation algorithm was implemented.


The driver has two adaptive modes (setting 1 or 3) in whichit dynamically adjusts the InterruptThrottleRate value based on the trafficthat it receives. After determining the type of incoming traffic in the lasttimeframe, it will adjust the InterruptThrottleRate to an appropriate valuefor that traffic.


This value delays the generation of receive interrupts in units of 1.024microseconds. Receive interrupt reduction can improve CPU efficiency ifproperly tuned for specific network traffic. Increasing this value adds extralatency to frame reception and can end up decreasing the throughput of TCPtraffic. If the system is reporting dropped receives, this value may be settoo high, causing the driver to run out of available receive descriptors.


This value delays the generation of transmit interrupts in units of 1.024microseconds. Transmit interrupt reduction can improve CPU efficiency ifproperly tuned for specific network traffic. If the system is reportingdropped transmits, this value may be set too high causing the driver to runout of available transmit descriptors.


The driver copies all packets below or equaling this size to a fresh receivebuffer before handing it up the stack.This parameter differs from other parameters because it is a single (not 1,1,1etc.) parameter applied to all driver instances and it is also availableduring runtime at /sys/module/e1000e/parameters/copybreak.


IntMode allows load time control over the type of interrupt registered for bythe driver. MSI-X is required for multiple queue support, and some kernels andcombinations of kernel .config options will force a lower level of interruptsupport.


Strip the CRC from received packets before sending up the network stack. Ifyou have a machine with a BMC enabled but cannot receive IPMI traffic afterloading or enabling the driver, try disabling this feature.


If set to 1, configure the hardware to ignore all write/erase cycles to theGbE region in the ICHx NVM (in order to prevent accidental corruption of theNVM). This feature can be disabled by setting the parameter to 0 during initialdriver load.


NOTE: The machine must be power cycled (full off/on) when enabling NVM writesvia setting the parameter to zero. Once the NVM has been locked (via theparameter at 1 when the driver loads) it cannot be unlocked except via powercycle.
