I'm running out of luck, My flopy drive doesnt work and My qflash can't flash with a USB drive. I'm gonna try to get a floppy drive from a friend , but, for now i'm gonna try the unebootin usb method to install Windows nt as a temporary solution...

This is normal behavior, Q-Flash only supports floppy.

Alternatively, you can update BIOS from clean MS-DOS. I use Windows 98 CD-ROM for this purpose.

Gigabyte's BIOS update archive already comes with the flash utility (FLASH891.EXE) and autoexec.bat command.

You need to unpack archive (7-Zip executable archive) to HDD with FAT32 partition.

I captured the complete update process on my motherboard for reference:

I also remembered this BIOS option that might help:

For installing and using Windows NT it is necessary to limit the maximum CPUID to 3

The attachment Limit CPUID Max to 3.png is no longer available

I hope this helps. Good luck!

Update: i have two brand new used iDE cables and now i can boot from any CD ROM, Made a quick test with old copy of Windows nt 4.0 and now i AM up an running, next step Will be upgrade My BIOS to the latest available...
