Case study Geforce GTX 960: The whole firmware size of this card is rather huge: 176 KB.

i think, u get broken image. full image must be 128 or 256 KiB... 😕

I do not think so 😀. I actually flashed the modified version of this firmware dump into my card and currently using it (memory clock is set to 3900 from 3500):

Also there are many different versions of BIOS dumps for Geforce GTX 960 cards that can be downloaded form the net ( I cannot find the exact version of my card's BIOS), and as you can see none of them is 128 KB or 256 KB anymore:
Asus GTX 960 2048 BIOS size is 200 KB: https://www.techpowerup.com/vgabios/167305/as … 0-2048-141220-1
Gigabyte GTX 960 4 GB BIOS size is 197 KB: https://www.techpowerup.com/vgabios/171453/171453

Edit:
Ahh, I have finally found it (or at least something very similar to mine):
Gigabyte GTX 960 2048 MB BIOS size is 176 KB: https://www.techpowerup.com/vgabios/167733/gi … 0-2048-141229-1
And as you can see it's verified since in case of non-verified BIOS dumps Techpowerup gives a warning just like in case of the Gigabyte GTX 960 4 GB BIOS.

I used the NSSI ROM dump.

We have new "king":

1) Its possible to check DOS VBIOS size / Vendor / Cardname, in Windows and Linux? If yes how? I know that you can make dump, but its i hope there is cleaner way..

Some video cards drivers replace the BIOS you have in Windows. So if you dump from Windows you get a different image. e.g. the driver for the DSystems Papilio G1-x cards does it. In Windows you have a BIOS that is fully VBE3.0 capable.

So you always have to check that the dump from within Windows is the same as the BIOS you get from plain DOS.

Ok, thanks good to know, i wanted to make things easier for people.. and it could still help with card model / brand identification. I dunno what HW indentification mechanism are using Aida and HWinfo (probably some Windows hardware ID + some lists of these IDs and card mapping created by someone without realHW testing), but there are lots of errors, fetch info from ROM would make a sense..

For PCI cards or newer a good way to go is checking the PCI Vendor and Device ID. This will not give you the manufacturer, but the exact chipset.

I wonder who is making these Device id - device names lists and it HW diagnostics guys, just download them, or buy them from some 3rd party companies and how much manufactures care about them? Vendors ID misrepresentation is not so typical as wrong detection - simply substitution right chip for wrong one, or simple info that device is unknown..
And there would be probably also second level mapping - with some specs details.. When i was younger i was naive and hoped that these tools actually trying to read these details from HW itself, not from some precooked text files / DB with some keyword - hardware id. I though that there is more lowlevel programming involved.

No quite, because it is an EGA. IIRC, IBM EGA standard video BIOS is 16KB.
Back then, IBM set the standard, everyone would adhere it, no question asked. The IBM VGA was the final standard that everyone would still follow. Subsequent IBM standards, such XGA and 8514/A, no one would care anymore.

I wrote myself that it is EGA and it no change anything on the fact that is card with smallest reported memory footprint.. If other EGA cards are 16KB good to know. For someone is EGA good enough, but true is that very old games not usually game problems with high free conventional memory requirements.

May I contribute an useful detail little known back in the 1980s and probably even less known nowadays:

Usually at the end of the VGA BIOSes there is the code for the alternate font and its font table.
This was/is a feature never used in practice.
So, with most VGA cards, you can use the last 4k of the VGA BIOS area as UMB RAM or EMS page window.

It looks like AWARD BIOS 4.50 cannot use more than 32 KB for graphics card BIOS on 486 computers.
A friend of mine is examining its initialization routines.
