Broadcom NetXtreme II 5708 Windows NT 4.0 driver

[ruthan]

I spend a quite a lot of time in the search for NT4 drivers for Broadcom NetXreme 5708 PCI-E cards.. I have classic not enough PCI-E / PCI slots problem, so i cant simply replace it. 
  There as usually some drivers for more modern Windows which has false description claims about supporting - NT4 it their description on some driver download sites, but after downloading in real readme NT4 arent in the list of supported OS. I have tried some Windows 2000 drivers, but they are not working.  

  So the last chance is try to ask here, because perhaps someone here has driver for it.. or has better driver google fu.. 
I have found and have on other machine working driver for previous generation Broadcom NetXtreme I - 5703 card.. (these are supported:
and driver which is working with Broadcom 5721.

 I have also tried to modify NT4 driver for 5703 by adding HardwareIDs of 5708 to it - its 164C at the end, but NT4 drivers *.inf which i found seems much more complex than other *.inf, so my edit probably not worked, because when i tried to add it.. Device name was detected with wrong name (or maybe it is using generic one until extract card is detected).. but 
  Maybe some has better *.inf modding skills. Others these cards has nice support of Everything from Dos to modern Windows, except NT4 and Windows 98 (but i already made Ndis2 dos driver working there).

Yea, on WinNT 4.0 works only some Broadcom chips. I bought several PCIe cards and only the third one worked:
https://www.vogons.org/viewtopic.php?p=1383896#p1383896

BCM57782 - not work
BCM5761 - not work
BCM5722 - work OK

I use this driver: 10.62.1.2 from https://soggi.org/drivers/broadcom.htm#NetX

My memory is not working well, but im like 95% sure that i already tried these..
 

Soggies drivers - they failed more than once for me, it could be about skill, but i doubt it.. Because you can download lots of drivers which claims that support HW X,Y,Z and some old OS, but nobody tested them and they worked worked, its very easy edit inf and add some new option..
  There are also drivers which simply claim NT suppport na never is mentioned lowest supported OS, so in theory they should work on NT, WIn2000.. but they never do, its often because some MS driver kit helper version, which rely on specific OS features..

Soogie and other Broadcom drivers work OK. Some Broadcom chips are simply not supported. I tried modifying the PCI Device ID in the .inf files but it doesn't help. Only the BCM5722 chips works with Soggie and other Broadcom drivers.

P.S. I also have an old IdeaPad S10e netbook with an integrated Broadcom and the Soggie WinNT 4.0 drivers work OK

Yeah, but description is really misleading, there is this text for NetXtream at the top :
BCM5700, BCM5701, BCM5702, BCM5703, BCM5704, BCM5705, BCM5714, BCM5715, BCM5718, BCM5721, BCM5722, BCM5723, BCM5751, BCM5752, BCM5753, BCM5754, BCM5755, BCM5756, BCM5761, BCM5764, BCM5780, BCM5782, BCM5786, BCM5787, BCM5788, BCM5789, BCM57760, BCM57761, BCM5762, BCM57765, BCM5901, BCM5906)
  so its wrongly guesting that it works in all OSes mentioned under it, there is not list per OS.. so its at least misleading and i even checked inf, but there is not classic list with names of devices..

 As i wrote 5703 in NT4 too - NetExtreme I line, at least with different drivers. Maybe even 5721 PCI-E is even working in Win9x.. but in WIn9x / Win 2000 you can use USB lan / USB wifi adapters when you got into problems.. in NT4 probably not.
