i hoped its simply fix main Dos problems for these new Nvidia cards.
No, the patch is very specific in this sense as it can be read in its description:
'MSKVBEF7 is a TSR that masks/hides VESA VBE Function 07h - Set/Get Display Start. It can somewhat cure the rather serious VESA BIOS bug of Nvidia Kepler/Maxwell/Pascal series that can cause flickering/skipped frames under DOS programs that use hardware page flipping for double/triple buffering.'
I have now Geforce 6600 GT in same machine, i thing that its from Gigabyte and its fine, im using FW as default FM, so i tested it with 50+ cards, ATI / AMD / Matroxes /S3/ 3Dfx.. all in my Dos videocards performance lists.. and Geforces from 4MX up to 730 DDR3 PCI-E all these new are ok, only these Nvidia with PCI-E gen 3 arent working with FW.
I have not said this non-standard VGA mode is also buggy with Geforce 6600 GT. I have just said that it's not buggy on Geforce Kepler/Maxwell because of VESA Bios bug since VESA Text modes are not supported by NVIDIA VESA Bios at all.
Here are some pictures what I'm talking about:
1.a. If VESA text modes are supported then you get something like this in FWIZARD:
1.b. And something like this in AIDA 'Graphics -> SVGA VESA Text Mode' section:
2.a. If VESA text modes are not supported then you get something like this in FWIZARD (as I said green means not supported):
2.b. And in AIDA:
In case of both Geforce 6600 GT and Geforce Kepler/Maxwell you get something like the 2. case: VESA Text modes are not supported at all.
But yes, Geforce 6600 GT and Geforce Kepler/Maxwell are different in the way that 720x400/90x25 non-stanard VGA mode is supported by Geforce 6600 but not by Geforce Kepler/Maxwell.
But this mode is not a standard VGA Text mode so the support is not 'demanded' by VGA standard:

The bug is triggered on Geforce Kepler/Maxwell when you select any modes represented by the 4th yellow 'X' column in FWIZARD.
I mean these ones:
Its some hungarian guy with pretty generatic name, i wasnt able to find some working contact.
I'm also Hungarian so I can say he does not have a 'general' name as far as Hungarian names are concerned. On one hand 3 names are not so general in Hungary (the typical is 2) and overall 'Gulyás Antal Dénes' is rather distinguishable. I have found some reference and it seems he was an active member of the community of late famous 'Enterprise 128' era in Hungary, but I also could not find an active contact.
But it seems you can reach 'Laci' at www.ep128.hu/ and maybe he can help since one of his pages refer to a program written by 'Gulyás Antal Dénes' and Laci's site seems to be still active (last modification date is 2019.03.30.)
