At last somebody answered ..............................
Thanks a lot titopoquito . Your suggestion to remove only the "rhgb" parameter worked fine. Now i can boot with runlevel 5 without any problems and my CD Writer is also working properly.
Sorry for that "ssci" thing. It was an error on my part it was actually "scsi" as you had mentioned
The link you gave me was also helpful.
Also could you please view another problem i am facing with my X server :
I got no replies for this thread. But this is also one of the major problems i am facing with my X server. Maybe you could help?
(I guess this is not against the forum rules?)
Thanks a lot again. You've saved me a lot of trouble.
