I am totally new and attempting to dual boot. I have a 3D Prophet II MX graphics card. I can't get the graphical installation. Should I continue installation and address the GUI problem later, or is there something I can do now before installing? Thanks for replies

What distro are you trying to install? If redhat or most others with a grpahical install, then you can install using the text based install by issueing text when it first comes to:

boot: text

That should start the text install instead of a graphical install. But be weary, if it won't load the graphical install automatically, theres a good chance you won't have any type of GUI after installing and only command line.
You might want to check out http://www.xfree86.org for compatibility with your video card, if you might need an update or new drivers for it.

I'm trying to install Red Hat 7. If I install w/Text option, will I be able to download the drivers needed for my card, or can I download them in Windows 98.
Thanks for replies!

Yes, if you have network connection, its probably easier to download with a broadband connection as ppp in the terminal can be confusing, but xfree86 has a ftp site you can go in and download the drivers from within the terminal.
Or you can download onto your Windows hard drive and you can actually access that from within Linux byt mounting your windows drive and copying the files from there. Might make it easier that way as you can just go to the website and read upon what you might need and what drivers you need.

Thanks trickykid, First I'm going to try the install on a smaller machine that red hat seems to like better for now just to get rolling with red hat. I will then go back to this machine, which is better, and try to work it that way. thanks again. I'm sure you'll be seeing me a lot!
