    • Had a few cards lying around I'd stockpiled so I could convert a couple of satellite X2's and so I have a spare for my TTX2's.

      Method-1 = flash with elsa bios
      Method-2 = edit bios and change card ID codes to match TTX2 ones.

      Dell 0HH748 7900GS - works fine with method 1.
      P455 Geforce 7900GS - works fine with method 1.
      Palit Geforce 7900GS - works fine with method 2, bricks card with method 1 (you just get random patterns on screen).
      BFG Geforce 7900GS OC - works fine with method 1.

      All tested with a legit Street Fighter IV drive and a V210A TTX2.

      Used an ECS NM70-M V1.1 motherboard with build in Intel celeron processor, booting from USB-pen to flash the cards.

      Now just need to upgrade my old RC2 TTX2 multi drive to whatever the latest version is.

      Can you talk a little more about method 2, when you have some time? I tried flashing an MSI card recently, and while the flash did succeed, I get really bizarre behavior where some games work fine, and others crash and burn at random intervals. Wondering if editing the BIOS would resolve the problems.
      Easy, method 2:-
      • Set PC to boot from USB as first device in bios.
      • Put 7900GS card into PC - don't forget the 6-pin power lead or it won't work properly.
      • Boot PC using a usb-pen with the image in the OP.
      • CD to TTX2
      • Run "nvflash --index=0 --save original.rom"
      • Remove USB pen from PC
      • Plug usb pen into a pc running windows
      • Run NiBitor
      • Open j:\TTX2\original.rom (assuming USB pen is J:\ drive)
      • Click on adv tab
      • change device-id to "0292" (probably this already)
      • change sub-vendor-id to "1048"
      • change sub-system-id to "0F09"
      • change board-id to "1901"
      • Click on "Boot settings" tab
      • Change card "display text" so you can tell it has TTX2 bios
      • Save to j:\TTX2\modified.rom (assuming USB pen is J:\ drive)
      • Eject USB pen
      • Boot PC using a usb-pen with the image in the OP
      • CD to TTX2
      • Run "nvflash --index=0 -4 -5 -6 modified.rom"
      • answer "Y" to all prompts
      • On my PC the caps/num lock lights flash during bios programming and it beeps once complete
      • Once complete reboot - if splash screen shows modified text then it's worked.
      • Put card in TTX2 and test with real HDD/Dongle or Niko's multi.


      If it doesn't work re-flash with original firmware, stick on eBay and buy a different card.

      BTW : if you get garbage on the display and you're PC hasn't got on-board video, don't panic, because you saved the OEM bios before you flashed the custom one didn't you...
      Assuming boot from usb is set to default boot order.
      • Reboot the PC with usb pen plugged in (you'll get nothing/garbage displayed on screen, so you have to assume it's booted OK).
      • press enter a couple of times
      • type "cd ttx2" - press enter
      • type "nvflash --index=0 -4 -5 -6 original.rom" - press enter
      • press "Y" 3 times - pc should bleep 3 times
      • on my PC the caps/num lock lights flash during bios programming and it beeps once complete
      • reboot pc - card should be restored to OEM BIOS.

      • STEPS

      So I'm taking a deep dive into the X2 hardware.
      I have been searching up and down in documentation but I can't find the reference thread I was looking for.
      I know in the past somebody has flashed one of these, and I'm kinda at a roadblock.
      While I have a 7900 GS that came with the unit, I would like max specs possible.



      In the steps above, where do I cange the clock values for this BFG 7950GT?
      If somebody has flashed one of these in the past, do you have your BIOS or settings on backup you'd be kind enough to share?
      I'll tip ya a 6 pack of beer via paypal.

      Thanks!

      Here is a custom ELSA 979 BIOS with a slight overclock I run on my 7950GTs.

      It fixes the slowdown thats present in a few of the more demanding games while being underclocked compared to the stock 7950GT for maximum life.

      @NikoI've just sent you $10.00 via Paypal FnF.
      Please buy yourself a nice 6-pack for your split second help while I got shit on the bench.
      I just got past yanking the backup bios, so all I trust I need to do is follow the steps with your Bios in place.


      Update:
      this BFG 7950 with your ROM image booted up like a champion.
      Everything feels incredibly snappy with the new proc and 4Gb of ram. (detects as 3.2)
      This has been a fun lil project.
      I need to now understand how hard drive images work, and look for all the legacy software dumps.
      I wanna play that Tetris game that's on here.



      Thank you good sir.

      Much respect.
