I think this comment was from Satish about ide=nodma. Why is that necessary? I've encountered the mediacheck failures similarly for the first time ever. If the drive operates normally, why do we need nodma in order to check only disk2 and disk3 of the CD set? Ans... I had similar trouble with FC2 install. I never had a problem with media check, but ran into a HANG issue when booting install or following install. I too questioned the nodma setting but was told not to worry about it. It seems to be related to a firmware compatibility issue with something on the IDE bus (Not necessarily your CDROM) But using nodma does not seem to affect operation or prevent/enable any functionality.. Just works. John Best jbest@xxxxxxxxxxxxx <mailto:jbest@xxxxxxxxxxxxx> Yahoo Msngr: JohnJBest
