I need to restore prefetch data for free


There's no need to worry about prefetch data. They're automatically generated by Windows to help programs you use often launch faster. But in the counterpart, when this folder get very "big", it becomes an issue to the performance of your machine. That's why some "cleaning" programs propose to delete the prefetch files.

I have a Satellite L305-S5918 laptop computer. When I turn it on,it goes to a blue screen and says it insert driver instalation disc


You will need to insert your windows installation disk during startup and perform a repair when it loads. If you do not have a windows disk then you will need to restore your system from a backup.
Either option you run the risk of losing any data so hopefully you have a backup. If not you may have to take it to a local computer shop and have the data recovered before carrying out any of the above.

Unix


Improving UNIX server performance NOTES.INI settings Most NOTES.INI settings that affect IBM® Lotus® Domino® server performance apply to all UNIX® platforms.
NSF_Buffer_Pool_Size_MB Many machines that run UNIX have very large amounts of physical RAM. Use the parameters NSF_Buffer_Pool_Size_MB or PercentSysAvailable Resources to control how much memory Domino is allowed to use. Each Domino instance on a UNIX machine can reference a maximum of 4GB of RAM.
Disk and memory requirements When a UNIX system runs Domino server software, the server must have enough disk space for program and data files and enough memory to handle swapping and the number of processes. You can also change several system parameters to improve server performance.
Disk I/O tuning Maintaining multiple file systems for operating system files, swap space, transaction logs, and data improves overall server performance.
Use RAID 0+1 hardware for the disk drives on which the data files reside. Use multiple smaller disk drives instead of a few large disk drives for Domino data. Domino does not perform simple predictable sequential reads; therefore, disable Read Ahead Cache and enable Write Cache.
Keeping swap space on its own separate striped volumes improves server performance at high loads. The transaction logs should always be on the most reliable and highest performing disk subsystem available to the system hosting the Domino server. Transaction logging must be on its own disk drives for improved server restart time, reliability, and availability. The logged transactions are written to disk as fast serial writes to a sequential file that is of configurable size in 4K blocks.
Console and database logging To improve server performance, limit the amount of information that is logged to the log file (LOG.NSF) and the console.

Re booth system


To resolve this problem, select the Delete restoration data and proceed to system boot menu option which enables the computer to perform a normal restart, instead of performing the restoration process while the computer is in Hibernate mode
