When you have ChatGPT, you can put the answer from Windbg with copy and paste there and just ask for next steps. ChatGPT does not know all about the Syntax of this Windbg version, so it will be a lot of try and error.

Dietmar Posted February 23 Posted February 23 (edited) Here is a new version of RTL8125 for XP SP3. I succeed, what even not win10 manages, to let it run on pure legacy IRQs. This makes it fast as much as possible, <1ms ping to DHCP router Dietmar Edited February 23 by Dietmar 3

This makes it fast as much as possible, <1ms ping to DHCP router Dietmar https://www.upload.ee/files/19103023/RTL8125forXPSP3Version3.zip.html I'm curious, why are you no longer releasing source? It would be nice to have that to be able to make a x64 driver.
Dietmar Posted February 24 Posted February 24 (edited) Hi, I learned soso painfull, that I have to edit the RTL8125.inf file. But now it is ready. This is by far the best driver, that I ever made, here also with Source Code, please test Dietmar https://www.upload.ee/files/19104527/RTL8125allbest.zip.html Edited February 24 by Dietmar
reboot12 Posted February 24 Posted February 24 @Dietmar This forum has a very low number of views - on average 5 users per day, so few people know that you made such drivers and there is no one to test them. I suggest making the drivers available somewhere that is more popular, e.g. record a short video on YouTube. Maybe also create topic on MDL forum - average members per day is about 100 but posts are hidden if you no account.
Dietmar Posted February 24 Posted February 24 @reboot12 I make a new i219v3 for you with new i219.inf and put its i219.pdb also in it. After my experiance with the RTL8125 driver yesterday I come to the idea, that maybe your compi needs just more information durring install from the i219.inf . Uninstall your old i219 in Device Manager. And then "search for new hardware". And point to this new i219.inf . If you get a message, that the device cant be found, click right on this i219.inf and click "install". Then reboot compi, Then point again in Device Manager to the i219. Do not delete this time the i219 there. Just "update driver" and show it to this new i219.inf. I just test this methode on my compi with the same i219-LM as yours, good luck Dietmar https://www.upload.ee/files/19105087/i219LMV3mitneuer_INF.zip.html
reboot12 Posted February 24 Posted February 24 (edited) @Dietmar Not work, 0 sent / 0 receive I have my own way to change the driver in WinXP and it always works - have been using it for many years: uninstall driver from Device Manager search oemx.inf file for the previous installed driver in WINDOWS\inf directory then delete this file (delete also same name oemx.PNF but not necessary) in Device Manager click the computer name at the very top and then Scan for hardware changes button now WinXP finds new hardware where you need to indicate the location of the new driver and install it Edited February 24 by reboot12

Damnation Posted February 24 Posted February 24 (edited) @Dietmar I added an RTC8125.rc resources file to your project just for the aesthetics, it's nicer with one. https://buzzheavier.com/ziftf00d8rg9 Also, when I build this with the windows 7 DDK - I got an inconsistent DLL linking error in NdisMInitializeScatterGatherDma and had to use #pragma warning(disable:4273) to get it to compile. Is that normal? Edited February 24 by Damnation
Damnation Posted February 24 Posted February 24 @Dietmar On the topic of NICs, I have an industrial ETX carrier board that has a late revision Realtek 8168 chipset (Rev. 15) that I would like to try and get working in Windows 98 SE. It works just fine in XP with Realtek's XP driver but transporting that same driver over to 98 causes a BSOD in NDIS.VXD, and the 98 driver on Realtek's website just gives a yellow exclamation mark if I install it, so I'd like to try and make a win98 driver following your example. Can you link me to the hardware documentation you've been using to make this these drivers?
Dietmar Posted February 24 Posted February 24 @Damnation Hi, I just look. how Linux, Reactos and FreeBSD build those drivers, look for their Source Code which is online available. And I use ChatGPT for to find online all the values for needed registers. Always I doublecheck this values. Then I start to build a sceleton of a driver, that just installs, without any send or get function. Via this way I can check all the time Bsods, Code 37, 39, 10 with Windbg and solve one by one. I really get much better in using Windbg. For to interpret all the for me unknown output from Windbg, I also use ChatGPT but this Interpretation was correct only in about 50%. 3 years ago I build my own small KI. And via this knowledge I know very good, how you need to ask a Ki for to get a not stupid answer. It happens a lot f times, that forums etc. tell wrong things, so I wonder how they ever can make a working driver from this information. Do you tested a Lan driver (i219 or RTL8125) from me and does it work? Yes, this warning happens to me also. At a place I make another definition of a function, that I define at another place before. The checked version compiles just with this warning, for the free version I have to delete this second definition of the function, as I remember just 15 lines cut Dietmar
Dietmar Posted February 24 Posted February 24 @reboot12 A lot of times I had the same problem with the Symbols for Windbg. But here you wrote the solution from yourself. Windbg is looking for its symbols in c:\symbols\symbols\sys\ so just be kind to Windbg and copy and paste all your symbols to this place also Dietmar
