Win95 NDIS IM Driver

Hi all,

I need a startup guideline to devlop NDIS intermediate driver for Windows 95. I finished with looking to IMSamp for the NT 4.0, and passthru for the Windows 98 and all later release. I need same devlopment stuff for Windows 95 too.

Another query: When i started with Windows 95 DDK, I found only few help-pages in that or say seems like a filler in DDK after reading help in NT 4.0/98/2000 DDK. From some site i knew that Help pages from DDK of NT 3.5 will do for Windows 95 also, but unfortunately I failed to locate that DDK. Can anybody sent me link to download that if it is really going to helpful…

Can i’ve initial break-through from the GURUS.

Thanks in advance.

Sumit,

I did a quick review of Windows 95 NDIS code and I don’t see support for
NdisIMInitializeDeviceInstance, which you will need to get XP/2K
PASSTHRU to port it back. You may have to resort to writing a pair of
VxD drivers. I believe that you can use the Windows 98 DDK to write
your 95 driver(s). You will have to limit yourself to NDIS 3.1 for
Windows 95.

Good luck

You can implement the functionailty if a NDIS Intermediate driver on Windows
95 through Windows ME with one VxD by hooking the NDIS wrapper using
Hook_Device_Service (and a little more…).

The PCAUSA NDIS Pseudo-Intermediate (PIM) driver framework uses this
technique. Mush easier to use install then a NDIS IM driver on Windows 95
through Windows ME. AND it works out-of-the-box with PPP.

See the following URL for a solution:

I can confirm it. We also use this way (based on Thomas’s idea and code) and
I’m quite satisfied with it. No problems with installation, works on any w9x
systems (yes, additional hooks were needed for wME) and works for PPP since
w9x which was our main requirement. It have some small drawbacks: no binary
compatibility with NT (chimera :slight_smile: and maybe a small performance loss.
Anyway, most code can be shared with NT version(s) and advantages prevail.

That is correct. A lot of developers used the hooking scheme – hooking
NdisRegisterProtocol (to get the handler addresses), NdisSend,
NdisRequest and a few other entry points until Windows ME came out.
That scheme stopped working because it relies on VxD/.386-based
protocols calling NDIS.VxD via VxDCalls. The Windows ME TCPIP stack was
implemented not as a VxD but as a .SYS driver and uses the PE
Loader/NTKERN to resolve entry points into NDIS.VxD, bypassing the
VxDCall hook. The trick, which you found, is to also hook
PELDR_AddExportTable to get the following entry points when NDIS
registers its export table with the PE Loader:

NdisRegisterProtocol
NdisDeregisterProtocol
NdisOpenAdapter
NdisCloseAdapter
NdisSend
NdisTransferData
NdisReset
NdisRequest

This scheme is unsupported and for compatibility I would generally
recommend writing actual IM drivers. But I offer the above for those
cases where the information is useful.
