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).
