That is what you said, with a quote from me in the middle of it.
You said many chipsets that support 4Gb or more.
Name them!
I wont even confine you to the chipsets that would be used by these small and medium size businesses, that would like to have used a consume OS as a server OS...
The scope is even wider than that, lets start in the NT4 era...
You cant, because they didnt exist!
Intel 440FX: Capped at 1 GB.
Intel 440LX: Capped at 1 GB (512 MB SDRAM).
Intel 440BX: The legendary enthusiast chipset was hard capped at 768 MB unbuffered / 1 GB registered.
Intel 440GX: High-end dual Xeon workstation chipset, capped at 2 GB.
The only chipsets from the NT4 era that addressed 4Gb were the Intel 450GX (Orion) and 450NX which were massive 4way/8way enterprise server architectures running on machines like the Compaq ProLiant 6000 and costing tens of thousands of dollars. The exact "enterprise mambojambo" you claimed small businesses never needed was literally the only hardware on earth that could physically take that much RAM in the NT4 era.
I think you only know the NT4 era from retro computing and then mostly in retro VMs because that is the only place you can get those old machines to support that much RAM because the hardware back then sure didnt!
Nvidia driver 333.11 was released in May 2014
A month after Windows XP reached End of Life, and ten full years after XP SP2 released in 2004.
Citing a 2014 Quadro/Tesla enterprise driver branch to argue how things worked in the early 2000s proves the exact point I made .You are retrofitting hindsight and cherry picking modern/late era drivers on modern platforms, while ignoring the complete lack of over 4Gb consumer hardware and consumer driver validation that existed when SP2 was actually written in 2004.
You mentioned 333.11 earlier, I dismissed it then because I thought it was a typo because it actually proves my point in more ways than one.
If a user in 2004 had to wait until 2014 to get an Nvidia driver branch that reliably tolerated high memory 32bit PAE addressing without crashing, that literally proves consumer drivers in the XP era were not ready, not tested, and not stable for high address PAE when SP2 was authored.
333.11 was an Enterprise Quadro/Tesla ODE Branch, Not Consumer XP
Look at what 333.11 actually was
It was an "Optimal Driver for Enterprise" (ODE) release for Quadro, NVS, GRID, and Tesla hardware (R331 branch).
Its release notes explicitly state "Discontinued support for Windows XP."
It was built for 32bit Windows 7, Vista, and Server 2008.
To run it on a consumer card under an uncapped 32bit PAE OS, you have to use an enterprise workstation driver branch from 2014, manually INF mod it to accept a consumer GeForce device ID, and run it on modern hardware.
This directly confirms what I said earlier: stable 4Gb and above DMA execution lived on enterprise certified driver codebases, not the consumer GeForce drivers that shipped on the CD with a GeForce 4 or FX 5200 in 2003.
Again this comes from a retro computing lens, not as we lived it back in the early 2000s
Your idea is that driver crashes above 4 GB were a myth invented by Microsoft to sell Server licenses, and that drivers always worked.
Well your own example of 333.11 proves you wrong.
With that one example you have to land on a hyper specific, curated, enterprise derived driver branch from 2014 to stop the machine from falling over.
So you have ZERO technicals to back up your idea about microsoft dumbing down the OS to force small/medium size businesses into buying server OSs.
The only crippling of the OS, in SMB, was actually part of the Microsoft billing structure! Client Access Licences. And even then that comes up as a request in the OS as to you having one, how many its for and only comes up in server OS and then only as part of a compliance review! So they would come to your business and inspect your licences, which aint going to happen!
And then we come to the cherry on top
MSBlast
You apply a solution from now to a problem back then...
I mean you know I dont know where to take that one.
You say you mention NAT and firewall protections, but none of them remove the problem with an unpatched system they just take it out of harms way, which is kinda beside the point. Microsoft needed to fix the problem not paper over it or mask it behind a wall of protection.
Thats the difference between being competent and professional and getting by with guile.
Its exactly like forcing WinXP onto a modern motherboard with an unsupported ACPI table (anything beyond ACPI 2.0). You can slipstream patches, bypass the 0x000000A5 stop error, and trick the installer into declaring the machine an "ACPI Multiprocessor PC." But the NT5.1 kernels ACPI driver still doesnt have the hooks or logic to properly parse power states, sleep vectors, or modern interrupt routing defined a decade later. Device Manager might look clean, and the system might boot, but you havent actually solved the architectural incompatibility youve just masked it with a hack. And a dirty hack at that.
Hiding a broken stack behind a router or masking an ACPI mismatch with an installer patch might satisfy an enthusiast tinkering on a test bench, but it doesnt change the underlying technical reality of the platform.
Which is what Im talking about.
