So, for flashing activities on a 6800 series card,
Flash the bios in DOS using nvflash.exe v5.25
nvflash -r (removes any protection)
nvflash -b ORIGBIOS.ROM (saves original bios)
nvflash -4 -5 -6 BIOSNAME.ROM (flash new bios file)
However because of DOS filename restrictions, "ORIGBIOS.ROM" and "BIOSNAME.ROM" must have no more than 8 char's in first part of filename and no more than 3 char's in extender part, otherwise DOS will not recognise the command.
And note; the -4 -5 -6 command switches will force a flash regardless of any ID mismatches, so always just select to continue.
Or, if wanting to use a blind flash floppy, then add the following commands to the "autoexec.bat" file,
nvflash -4 -5 -6 -A BIOSNAME.ROM
That worked, using 5.25 with -4 -5 -6, I think it was because I was using older commands like -p -e -u that i read on a website that made it stop the process, but it works now. Thanks for your help every1
