Linux Redhat6 is unable to detect my "Display adapter"

["rizwan younus" <dr_riz hotmail com>]

Hi to everbody there!
                   I am new to linux and installing it from a bootable 
cd.The 1st time i instlled linux my vga card which is SiS620 was detected 
and X window was installed(gnome);but the problem was that the desktop area 
was very big at least 3 times larger.So i removed the linux partition and 
tried to install it again with correct configuration but this time linux was 
unable to detect the vga card and i tried hard to some how make it detect 
but in vain.Now linux is installed in text mode only.
By the way my system has other 2 partitions containing windowsNT(NTFS) and 
Windows98(Fat16). I am also having problems in configuring LILO.
Although i read the articles " how to install linux with windowsNT" but due 
to the desktop problem was unable to solve the LILO problem too.
Can anybody help.??
                    I would be greatly thankful.
                                                 Regards.
                                                  Dr.Rizwan.
