It's really easy to get the Bios from your graphic card, there are two ways of doing this, if you have a Floppy-drive, a partition formated with FAT, or other kind of media that you can use to save files on from DOS, you can use the step 1, if you don't have this pre-requisites you need to use step 2, it's safe if you just do what i'm going to explain...
If you don't have a floppy-drive with Windows 98 boot files, you can burn the boot.iso on a CD-RW, and then reboot and start the pc from the CD-Rom, to do this you need to press F12, if you have it enable on the bios, if you don't have press F2 and go to boot options, and choose to use F12, save and reboot, and use the option start the computer with cd-Rom support, when the PC is started write this command on command line:
nvflash -- save A:\Bios.rom
note:If you have a partition formated with FAT you have to find is letter and then put it instead of A:\, if your partition is F:\, the command will look like this:
nvflash --save F:\Bios.rom
