-# DoomGeneric NTNative
-This is a fork of ozkl's DoomGeneric which adds port to the BootExecute environment of Windows XP and later.
+# DoomGeneric NTDrv
+This ports DoomGeneric NTNative to kernel-mode driver environment.
 
-# Requirements for building DoomGeneric NTNative
-1. Visual Studio 2017 Windows XP toolset.
-2. InbvShim (https://github.com/Cacodemon345/inbvbootdrv).
-3. Windows 7 DDK (for building InbvShim and ntdll.lib).
+# Requirements for building DoomGeneric NTDrv
+1. Windows 7 DDK.
 
 # Requirements for running
 Only tested on Windows XP 32-bit. I don't know about later versions.
 
 # Building
-Note: Only 32-bit Debug builds are supported, anything else is broken.
-Copy over the ntdll.lib file from \\path\to\WinDDK\7600.16385.1\lib\wxp\i386\ to the doomgeneric directory inside the project. Open the solution, right click "doomgeneric_nt" and select "Build".
+From the x86/x64 Free Build Environment, cd to the directory where you have cloned this repository, and type 'build' to build the driver. You will find the doomgeneric_ntdrv.sys file in the objfre_wxp_x86 (objfre_win7_x64 if building for x64) folder.

+# Installing DoomGeneric NTDrv
+Copy it to your system32\Drivers directory of your Windows installation. And then grab the doomgenericntinst.reg from one of the releases and double-click it to install.
 
-# Installing InbvShim
-Copy it to your system32\Drivers directory of your Windows installation. And then grab the inbvbootdrvinst.reg from one of the releases and double-click it to install.
+# Running
+You need my fork of NativeShell to start DoomGeneric NTDrv.
 
-# Installing DoomGeneric NTNative
-Copy doomgeneric_nt.exe to C:\Windows\system32\ directory.
-There are two ways of launching it:
-1. Registry modification:
-
-**WARNING:** Backing up the registry is very important before going down this path.
-
-Open Registry Editor (regedit), go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\. Double-click BootExecute.
-
-Replace this:
-```
-autocheck autochk *
-```
-
-with:
-```
-autocheck autochk *
-doomgeneric_nt -iwad \??\C:\Windows\doom2.wad -cdrom
-```
-
-Replace \\??\C:\Windows\doom2.wad with the location where the IWAD is installed (remember to prefix it with \\??\ before the full path).
-
-Note that I don't recommend this way because it can make input non-functional, making it impossible to quit the program and requiring a hard reset.
-
-2. Native Shell (assuming you installed it beforehand):
-
-cd to the directory where DoomGeneric NTNative is installed and type:
-```
-doomgeneric_nt.exe -iwad \??\path\to\iwad.wad -cdrom
-```
-
-Replace \\path\to\ with the location where the IWAD is installed.
-
-# Extra bonuses:
-1. 16-color mode for Windows GDI port activated with -4bit option.
+Type 'doomstart' to start it. It expects the Doom 2 IWAD to reside in C:\Windows\ at the moment. Command line arguments are ignored.
 
 # Bugs:
 1. Savegames are broken.
-2. Picking a weapon crashes the program (bug inherited from original DoomGeneric).
+2. Picking a weapon crashes the whole system (bug inherited from original DoomGeneric).
 3. It's slow as hell, probably could use FastDoom's EGA drawing code for it.
