first of all, your best bet is to use the nvidia driver installer package available here http://www.nvidia.com/object/linux_d..._1.0-4496.html
download the file NVIDIA-Linux-x86-1.0-4496-pkg2.run in win98 and copy that file to your linux home directory (or just use the console program "ftp" in linux). you will also want to download and probably print the README file ftp://download.nvidia.com/XFree86/Li...496/README.txt
because you have to make some changes to /etc/X11/XF86Config.
boot to linux, load up a console (terminal) window, and go to the directory you downloaded the installer to. switch to root, type:
note that you will need to enter the root password that you set up when you installed redhat. insert and mount (type "mount /mnt/cdrom") redhat 7.0 installation disc 2 and install the linux kernel source, type the following followed by pressing the TAB key before pressing ENTER to execute the command:
rpm -ivh /mnt/cdrom/RedHat/RPMS/kernel-source
install the nvidia driver:
now, follow the README file that you should have printed earlier to edit the /etc/X11/XF86Config file. good luck.
