Thanks to all again
@BMW = I already did that. Read it.
@Romeo = Sorry bro. But Whenever I'm trying to boot in safe mode then it fails to go beyond the command prompt.
@Apoorv = But I'm getting a display. I can view the logon screen. And 64 MB is alloted to the inbuilt video.
@Nishant = Little bit more info or perhaps a detail tutorial on that.
@Goyal = Link checked. Didn't help much.
@Vyasram = ????????????????????????
