I know nothing about Linux. But it's my job to figure out how to install Redhat ES 4 on a Dell Poweredge 1950. During the first part of the graphical install it says there are no hard drives found and that I have to install device drivers. I have the Dell disk with the drivers on it. So I click on Add Device. The GUI says that if I have a disk press F2. I do this and it says "Insert driver disk into /dev/hda and press ok to continue" I'm not sure what /dev/hda is. I can't open the CD drive. Nothing happens when I press the open button. Any help would be appreciated.
