NDIS6 support for XP?

[Dietmar]

@Mov AX, 0xDEAD

can you see, why the i211 works with kdnet.dll (better kdstub.dll) from win8.1

but the i219 not

Dietmar

EDIT: I see, that only the i211 gets attention in kdstub.dll and this via e1000_init_nvm_params_i211 proc near.

So, may be that for the i211, i217, i218 those nvm parameter are the same.

But nvm is different on i219.

 

EDIT2:

The i211 has a transmit buffer of 128 KB and a receive buffer of 128 KB.

In contrast, the i219 has a larger memory cache with a transmit buffer of 256 KB and a receive buffer of 256 KB.

 

EDIT3:

The i211 has a NVM size of 64KB.

The i219 Ethernet controller uses a larger NVM size of 256KB.

Is there a Vista bit32 driver for i219

Dietmar

EDIT:

This is, what I have found for Vista bit32.

The driver with "r" goes up to i210 and may be worth a try.

This "r" driver fullfilles all dependencies under win7 SP1, but does not work direct for the i211 or i219

Has anyone thought about or managed to add the support for NDIS LWF drivers to XP in this forum? What about WFP?

Because I think these two are a very important part of supporting many of vista+ programs.

@Dietmar

I thought I'd try and take another shot at porting NDIS 6 to XP.

I got a D1 BSOD in netio.sys this time.

My most recent build if you want to try and debug, no rush.

edit:

looking at your last debug log from when you got a D1 BSOD i netio.sys I looked at the point of failure in a disassembler and from what I can tell I think it has to do with the hashtable functions that I stubbed, might try to implement.

@Dietmar

Now I get a D1 BSOD from ntoskrn8.sys itself.

most recent build.

I'll stop for now.

I just test, that your ntoskrn8.sys together with the files from Longhorn 5048 is

downward compatible with i211 on the Asrock z370 k6 board.

So, just now on this board runs ndis6 under XP SP3

WOW, How to patch driver for the WinXP 64-bit?

[Damnation]

@Dietmar

I thought I'd have another go at trying to get Windows 7 ndis.sys to work on XP, now trying using AI to help reverse engineer assembly into C.

This time round I get a 7F 0.0.0.0 Divide by Zero BSOD.

If you have time, can you try and find where it's happening in ntoskrn8.sys?

[Dietmar]

@Damnation

This way will not work.

There are registry entries from Win7 and a lot more.

The "easiest" way would be something like this.

It is like for me to make a Graphik card to work in XP, which work hardly in win7

XP NDIS6 BRIDGE v1 – EXACT FILE LIST WITH FUNCTION NAMES
========================================================

Goal
----
Build the first bootstrappable version of an XP-side NDIS6 bridge for ONE wired Ethernet miniport family.
This is NOT a full Vista/7 stack. It is a narrow, instrumented v1.

Build products
--------------
1) n6host.sys
   - hosts the target NDIS 6 miniport
   - exports the bridge-side NDIS6-facing services/callback environment

2) xpim.sys
   - XP NDIS 5.1 intermediate/virtual miniport side
   - exposes an XP-visible adapter path

3) optional later:
   - importscan.exe
   - oiddump.exe

Directory layout

======================================================================
6) ABSOLUTE MINIMAL FILE SET FOR M1
======================================================================

If you want the FIRST buildable milestone only, build these files first:

glue/glue_recv_path.c
glue/glue_link_state.c
glue/glue_caps.c

======================================================================
7) FIRST IMPLEMENTATION ORDER
======================================================================

Step 1:
- common/*
- n6host_main.c
- xpim_main.c

Step 2:
- n6host_exports.c
- only the exact imported NDIS helpers needed by one chosen miniport

Step 3:
- n6host_miniport.c
- xpim_miniport.c
- xpim_protocol.c

Step 4:
- glue_oid_map.c
- n6host_oid.c
- xpim_oid.c

Step 5:
- bridge_nbl.h
- n6host_nbl.c
- glue_send_path.c
- glue_recv_path.c
- n6host_send.c
- n6host_recv.c
- xpim_send.c
- xpim_recv.c

Step 6:
- link state / reset / trace / caps clamp

======================================================================
8) WHAT TO CODE FIRST IN n6host_exports.c
======================================================================

The first exported/support functions to implement should be exactly these:
- NdisMRegisterMiniportDriver
- NdisMDeregisterMiniportDriver
- NdisMSetMiniportAttributes
- NdisAllocateMemoryWithTagPriority
- NdisFreeMemory
- NdisAllocateSpinLock
- NdisAcquireSpinLock
- NdisReleaseSpinLock
- NdisInitializeEvent
- NdisSetEvent
- NdisWaitEvent
- NdisAllocateNetBufferListPool
- NdisFreeNetBufferListPool
- NdisAllocateNetBufferAndNetBufferList
- NdisFreeNetBufferList
- NdisGetDataBuffer
- NdisOidRequestComplete
- NdisMSendNetBufferListsComplete
- NdisMIndicateReceiveNetBufferLists
- NdisMReturnNetBufferLists
- NdisAllocateTimerObject
- NdisSetTimerObject
- NdisCancelTimerObject
- NdisFreeTimerObject

That set gives the best chance to reach:
- DriverEntry
- miniport registration
- initialize
- OID traffic
- first send/receive skeleton

======================================================================
9) FIRST SUCCESS CRITERIA
======================================================================

M1 is reached only if:
- both sys files load on XP
- chosen NDIS6 miniport reaches InitializeEx
- core OIDs complete without crash
- one send completes
- one receive is indicated and returned
- repeated halt/restart does not leak or bugcheck
