How to install and load Windows 7 without CSM with NVIDIA GTX 960 card?

UefiSeven and Vgashim doesn’t help me. Flashboot 3.3k program is very well, but videodriver GTX 960 is not started.

This device cannot find enough free resources that it can use. (Code 12).
If you want to use this device, you will need to disable one of the other devices on this system.

What is VGA arbitration in motherboard? I can load Windows 7 with CSM only? Do you have loading method without CSM with card NVIDIA, but not AMD or Intel? Integration driver doesn’t help me. Delete/off vga.sys and vgapnp.sys doesn’t help me also. Disable devices in motherboard/device manager doesn’t help me. I haven’t analog equipment graphics card AMD or Intel to check Windows 7 without CSM. Can you help me? I am angry.

Hello, Fernando. Do you have solution my problem? Can I use GTX 960 in Windows 7 without CSM/Legacy? How fix error 12?

@kukonosau

Not really. Did you already update the BIOS of the mainboard and the graphics card?

@Fernando
Only motherboard BIOS, latest version, 5606. I don’t know how update BIOS my GTX 960 card. I worry that this card crashed without programmer instrument. I buyed Flashboot 3.3k yesterday, and I have error 12 also. But other devices working very well!!! Resolution very well!!!

@Fernando
Hello. Unfortunately, I have latest version BIOS my GTX 960 graphics card. I check in techpower site. My motherboard ASUS B350M-K willn’t working on Windows 7 without CSM? But if I enable CSM and install Windows 7 with all drivers system begin lagging in Fraps, GTA IV, GTA V. Maybe, chipset drivers crash or BIOS. USB crashed in our time Rufus, for examle. But if I use Rufus in Windows 7 without CSM and without NVIDIA driver (error driver) USB is not crashed! Therefore I can install Windows 7 without CSM and with NVIDIA driver, but latest it is not started in Windows 7 without CSM. Vgashim, UefiSeven doesn’t help me. Flashboot always help me going to desktop Windows 7 without CSM, but not active videodriver (error 12). Also in our record Fraps in Windows 7 without CSM hard drive, probably, DISABLE!!! This is not good when in high load disk disable! Can you help me install Windows 7 on Ryzen 5 2600 without problem without CSM? 3 years is not results((( I checked different drivers. Probably, Windows 7 part uncompatibility with my CSM BIOS or this is bugs.

@Fernando
Even discreet additional controllers USB 2.0 from Moschip, SATA (ASM1061) and so on doesn’t fixed problems!!! Even latest or old drivers doesn’t help me!!! I don’t know how demand Windows 7 stable working on my platform. I don’t want Windows 8/8.1/10/11. It is don’t fully support directx low 9 version, for example Vice City or GTA III unstable frametime graphics and other directx 8.1 games. Can I started NVIDIA driver in Windows 7 without CSM? Vgashim and UefiSeven apply error:

Unable to claim IVT area at 0000 (error: Not Found)
Int10h IVT entry could not be modified and current poiting
at a wrong memory area (9000:0000 instead of C000:0200).
Press Enter to try to continue.

I haven’t other graphics card, only GTX 960. I read FlashBoot caution for NVIDIA without CSM in Win 7, but I don’t know solution problem. Other drivers in Windows 7 without CSM working probably if I use FlashBoot latest version. How demand GOP Protocol Windows 7? Remove/disable vga.sys/vgapnp.sys doesn’t help me also. I have not idea(((

@kukonosau
As I already have written, I cannot help you. The combination of modern hardware with an outdated OS is not my area of expertise.

@Fernando
Thanks. Unfortunately( But said, Ryzen must bad working in Windows 7? Ryzen is uncompatible with Windows 7? Why then AMD site and motherboard site has chipset drivers? I don’t understand. If you don’t help me maybe you know who can help me?

@Fernando
It is good that B350 chipset don’t fully work in Windows 7? It is usual action? This is not surprise? Nobody can help me and said about Ryzen on B350 chipset with Windows 7.

AMD AM4 platforms can work well if bios enable CSM. But not all mainboards. Asus AM4 has an xhci bug with its bios on win7. For asus am4 boards, you need use combined mod xhci driver.

@canonkong
Thanks for answer. But ASUS has xhci bug only or SATA AHCI bug also? Because I have random lagging Fraps in Win 7 on ASUS, because hard drive, probably, disabled. I show test Victoria HDD some people, but are said that HDD is disabled sometimes!!! Windows 10 haven’t this problem, but I don’t use Windows 10. Can I start Windows 7 NVIDIA driver without CSM? Do you have method? Or I must use CSM only?

@canonkong
When I disable CSM and use FlashBoot Windows 7 (NVIDIA driver off) then USB is WORKING PROPERLY!!! Why? Causes is CSM BIOS? I don’t understand. Maybe, HDD will be working properly also without CSM? I want to be enable graphics card driver NVIDIA in Win 7 without CSM. I don’t want have error 12.

All DIY brands mainboards cannot work with flashboot pro,it will code 12 error because bios have some IRQ problem. Even you not meet code 12 error,cards can drive but all funtion can not work. It only can work for OEM platform and not support Nvidia 16/20 cards and AMD cards.

@canonkong

It only can work for OEM platform and not support Nvidia 16/20 cards and AMD cards.

But I have MSI NVIDIA GTX 960, I haven’t 16/20 series card NVIDIA. Can I fix error 12 without CSM on ASUS B350M-K? Windows 7 with CSM sometimes unstable working, but have best result FPS. Or Windows 7 MUST BE unstable working on my platform?
