Red Hat Enterprise Ed: setup crashes while verifying the media. Kernal Panic.
LINUX 9: setup cannot find DVD ROM drive
LINUX 8: setup cannot find any of the harddisks

also all the setps start in text mode and the mouse is always unavailable. what steps do i have to take to install linux on my system

By Lnux 8 and 9, do you mean RedHat Linux 8 or 9?

Which version of Red Hat Enterprise Linux?

In any case, it sounds like you are trying to install versions which are very old and do not support your hardware.

What is the make and model of your motherboard or system?
