Some updates.. I'm trying with the nvflash version 5.13 that in the EEPROM list should support the chip of my card SST 29E010 at least is specified inside but the few progress I did were into safe mode of Win 98 where the card is recognized into the program booting with an ISA card, with "Adapter: RIVA TNT (10DE, 0020, 1102, 1011)" but with a message with PCi Subsystem ID different from the only firmware I've found also cause the card one seems read as "invalid" with a Version:Unavailable (Invalid) ID: 0000 : 0000 : 1102 : 1011 while the firmware I've found has a Version 02.04.18.00 ID: 10DE : 0020 : 1102 : 1015 (and this last numbers would differ anyway maybe is another PCB revision). Anyway even forcing the update it abort with the EEPROM ID (6B,2b): Unknown ERROR: Supported EEPROM not found message. The bios chip is listed by this version so could it be a damaged bios? How can I force the flash? And where I can find other Creative CT6710 video bios files?
put both cards in, you can boot the computer with the isa card, go to windows, install the tnt drivers (preferably 2.x), reboot, disable the isa card in resolution control panel, making the tnt1 as primary, and the tnt1 should work
