Fixing the TNT once and for all

- In this video I will fix up a TNT card I started working on in another video.
I take no responsibility if you try anything I do!
If you want to see the previous video of this card you can use this link.

If you want the UT OpenGL render from Chris Dohnal you can find it here.

If I recall version 3.4 is the only one I got working in Windows 98, the later versions are intended for Windows 2000 or newer.
now trust me, this restored computer can run hundreds of games 2D as well as 3D from the 90s reliably for next two decades. if you like information technology, retro computers it is satysfying to see this retro beige pc's beign restored. your 1998 quest has been completed successfully
It will probably survive me 🤣
The bios bit flip part was very interesting! 👍
Finally a TNT gets some well deserved love. I love the detail work on the cable and screws. Looks great. The TNT was the beginning of Glide's end. It was pretty clear that game devs wouldn't want to support an additonal proprietary API for such little return. Also, strange thing that the VGA ROM checksum wasn't verified by all boards. I wouldn't have expected that at all. Bit flip of the year!
Yea that bit flipp was odd.
idk enough about how a MB loads the Vbios, I just know I had to recompute it for a S3 bios I modded not long ago, or they wont post.
I figure there should be a standard and it seems my board ignores it. 🤣
A really solid build, I like it.
Good job sir!
Some great deduction with the TNT bios bit flip, so weird it was only the copywrite date in the bios splash screen that flipped a bit. Is the checksum bit check a common thing in all GPU bios'?
I dont know enough about how bioses works or how a PC decides if a VGA or Option bios is valid and should be loaded or not.
But m old S3 card has this check.
Im fairly sure some check is done on most cards but how it actually works that I dont know yet.
Modern card seems to encrypt the bios, after all Nvidia likes to look down the modern cards so you cant mine on them at full speed and stuff.
Great video! I have an identical card, and I too added a fan to it (wrestled out from some MX200 card I think), though your mod turned out better-looking. Please, what flux are you using?
I have some old Amtech so basically what Louis Rossman uses.
There are other options nowadays.
@ Should read "old" as "impossible to find nowadays"? :D
@@nicushorul2007 No, but Amtech has a best before date on there flux.
But from what Im told it last longer then that.
If your in the US you can check out Louis Rossmann's store, this one probably works.

They are often fake on ebay from what I read.
You can try Krisfix in Germany if your in the EU www.gpufix.de/en/amtech-nc-559-asm-tf-010.html
I have not bought from them but both have excellent reputation on YT.
They have other fluxes also, read the description so its suitable for what your doing.
Just wondering, have you looked into the changes needed to use the onboard regulator if one would fit it on?
I had a Riva 128 around these times, damn I wished so hard I had a TNT back then
I know one pad has 5V on it that I remember so that should feed the regulator I would think.
There are a few 0ohm resistors on the back so my guess is you remove those to isolate 3.3V from the Core voltage.
But thats just speculation, I have not verified my theory.
@ Your theory is a good as mine, that sounds about right, thanks! :)
How did you turn on multitexturing in quake II 16 bits? As I know drivers turns it off
banshee är väl ett pci kort? Trodde att TNT skulle dra mer nytta av att det är AGP men kanske inte var så stor skillnad som jag kommer ihåg
Dom fins som både PCI och AGP.
AGP bygger dock på PCI bussen och 3dfx nyttjar inga AGP specefika fuktioner ändå så enda fördelen med AGP är 66Mhz bussen.
Dock kan vitt jag vet alla 3dfx kort från Voodoo2 och framåt köra 66Mhz PCI buss så ja har man tillgång till det så spelar AGP än mindre roll.
TNT kortet är snabbare, ganska mycket så med man behöver en P3 700 eller nåt sånt för att få ut det exta.
Det beror mest på att glide kräver midnre CPU än OpenGL eller DirectX.
Så TNT skalar bättre med en snabb CPU sedan har det ju en extra TMU villket Quake 2 drar stor nytta av.
Men på mer periodisk korekt CPU så blir skillnaderna inte så stora.
I wonder if there was an aborted or bad bios update. I feel like the odds of that particular bit flip are insanely low.
Some cards like the Matrox G400 likes to corrupt the bios and matrox even have a blind flash tool forr the G100 to G400 series.
We also had people with 3Dfx Voodoo3 and up having corrupted bioses on our discord.
I guess there might be cases where something can be written to the EEPROM by accident.
CuriousMarc on YT had a Pentium 2 portable system that would corrupt the motherboards bios if the IDE cables where inserted the wrong way, doable if the cable and MB dont have any of the keying stopping it.
I never heard or seen that on any other system but on that one it happened twice I think.
I think maybe something happened to it that wrote that bit and bricked it, intentional flash attempt or just some something that was just a fluke.
Bit of a mystery anyways..
