m Boot disc, and then type Root command to enter single user mode. At this moment, super user prompt # would appear;
-Use command “mount/dev/fd0135ds18/mnt” to install Boot disc onto the hard disk, and then recover the unix file under disk root directory with command “cp/mnt/unix/”;
-Remove the Boot disc from hard disk with the command “umount/dev/fd0135ds18”;
-Keyed haltsys to turn off system; remove Boot disc, and then the failure is eliminated, system could boot normally;
-After system boots normally, enter super user, change the host and group of the /unix file to system originally defined bin and mem.
3) Probably this is caused because improper startup/shutdown, which makes some material on disk damaged (hope it’s logical damage). Start the machine with XP disc, enter to main console mode, run CHKDSK /R to check up and repair disk error (according to different sizes of hard disks, it takes different times, usually, half an hour).
Suggestion: after backing up important data, it would be a better strategy to partition, format and reinstall system. As after the process above, such failures would still happen probably! If it’s OEM XP, you’d better to update all patches for system, in case something happen you cannot forecast.
