To make the driver use the kernel extender, in the import section, rename ntoskrnl.exe to ntoskrn8.sys (obviously ntoskrn8.sys needs to be in the same directory as the driver so it works). If driver is designed for only windows 8 and newer os, Security_cookie (4EE640BB on 32-bit file, 32A2DF2D992B on 64-bit file) can be changed on hex editor to random value (first match only). Save the respective file, re-open the same file and refresh checksum and save again. To check the dependencies of the file, use Depedency Walker to check for missing imports. If there are problems, please post screenshots. Edited January 12, 2023 by UsefulAGKHelper 1 Link to comment Share on other sites More sharing options...
265993303 Posted April 22, 2023 Share Posted April 22, 2023 I have dual boot with Windows Vista Ultimate 32-bit on Dell Precision M3800, I'm trying to install the driver for Intel(R) Dual Band Wireless-AC 7260, I did the compiling of ntoskrn8.sys and the renaming of import as well as update checksum, and yet it still won't detect the driver in there.

Check this driver with Dependency Walker to ensure that there aren't any missing imports on ntoskrn8.sys. Link to comment Share on other sites More sharing options...

Check your INF, it's probably system locked (6.1) and needs to be modded too. Link to comment Share on other sites More sharing options...
265993303 Posted April 26, 2023 Share Posted April 26, 2023 After lowering system restriction, a lonely NDIS.SYS dependency is left.

There's no known way to solve NDIS dependency problem. In theory, it is possible to fix NDIS dependency in a similar way to ntoskrnl_emu, but only a few people, including @Mov AX, 0xDEAD, can do it. Masters in the field tried to do something similar for Windows XP, but without success. Link to comment Share on other sites More sharing options...

NDIS 6 is new framework, that's problem, if think it is not easy to make it compatible with XP kernel even all missed import will be solved. Another way is emulation NDIS6 features based on NDIS5 source code, but it requires a lot(?) of programming Link to comment Share on other sites More sharing options...

Dietmar Posted April 27, 2023 Share Posted April 27, 2023 @Mov AX, 0xDEAD The Vista Longhorn version 5048 has ndis6. I tested lan driver from XP bit32 for i210 and i217. Both work with 5048 ndis6. But the i219 win7 bit32 lan driver has one missing dependency to the ndis6 from Longhorn 5048 Dietmar Link to comment Share on other sites More sharing options...
