Dear Lister: I am not sure which list I should put this mail. Actually I have some question about the old Red Hat 5.2. I installed RH5.2 last year and had run it for a year. Recently I modified some crontab files (which is probably the causes for my problem) since I don't want the system to remove the temp files automatically, because I run a big job needed at least one month. However, during that job running, the x-window crashed although the job and the system was still on. Once the job finished, I reboot the computer (P2 300 with 128M RAM). However, I can't get the computer start. Boot from harddisk, the final following error appeared: Kernel panic: VFS: unable to mount the root fs on 03:05 If I boot from rescue mode, the following error appeared: Unable to open the initial console. So I want to reinstall the RH5.2 without reformat the hard disk, is it possible? Since I have lots of important data on this hard disk. Although I have RH 6.0, I still want to keep RH5.2. Thanks a lot for any hints! Best regards, Wei Quan Tian University of Guelph Canada -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
