I will try the 2.0 but I'm flashing on a Radeon 9100 IGP motherboard (P4R800-VM). Only one I got with this BIOS IC and socketed. +++ Same problem with the 2.0 version. Tried both IC's and multiple .ROM and even .AMI files, identical errors. You can also try flasher provided by board manufacturer ( …

Ok, I got Uniflash 1.40 booted from FreeDOS USB, swapped the BIOS chip on the fly, detected again (even though they are all the same type) and after offering it the P4P81019.ROM file, it tried to flash but failed with FLASH DATA VERIFICATION ERROR. Tried 2 different chips of the same type but the …

if you have another motherboard with the same bios socket you can hot swap the chip with uniflash, doesnt have to be the same chip, uniflash has an option to re-detect the chip before you flash. I'm not 100% sure that the above sentence is always correct. Not only does the socket have to be the …

I don't think you can program parallel flash/eeproms with CH341. AFAIK it only supports serial ones (I2c, SPI, Microwire). Edit: I've looked into your flash chip specification - it supports 2 modes: FWH (Firmware Hub) and LPC mode. So far I don't have any experience with LPC mode, but I've …

The Gigabyte GA-Z97-HD3 worked quite well for me with the Audigy 1 (SB0090) on Windows 7 and Linux. I still have that board and card and can check again for you if you want. I did not test the Audigy 2ZS because unfortunately I do not have it 🙁

Thank you ! I think that Powerstrip is able to overclock Voodoo 1 (and underclock a little - to 48 MHz). It stores clock value somewhere, which is applied when Windows is restarted, even if Powestrip isn't configured to launch itself at startup. Everest Home edition can display 3dfx frequency (and …

I have found one OpenGL 1.1 Benchmark tool so far for Win9x. Other OpenGL Bencmark tools need OpenGL 1.2 or newer OpenGL support that Rage3 cards do not have. This has nothing fancy, just simple OpenGL tests and it works with Rage3 cards. It generates log and csv file after test is finished. What …

MX400 on the picture above is AGP version not PCI. So, if your motherboard doesn't have AGP slot - take Radeon 7000. Otherwise MX400 is much faster, and much better choice (even better is Geforce 4MX 440 128bit - twice as fast as 2MX and in the same price range). BTW: What is your CPU and …
