        1.) INSTALLATION


            To install the Utility drivers in a floppy disk or hard
            disk, please use the installation program  called
            "install.exe" which is included in this diskette.

                The install program will modify (or create) a file
            "config.sys" in the disk on which drivers are going to 
             be installed, and will copy the required drivers to 
            that disk.
             
                After installation, reboot your computer using the
             modified disk. The installed drivers will be available.

                If there is any error during installation, the
            install program will show you the error message. Please
            fix the error first, and then run the "install" again.



        2. DRIVER DESCRIPTION


              For a XT mother Board with 1024KB memory size, there 
              should be 384KB Virtual RAM. Those RAM can be used to 
              perform a RAM Disk, Printer Buffer or Hard Disk Cache.

            

                a. RAM Disk  

                        A file "CDISK.SYS" in this diskette is a
                   device driver which simulates a disk drive by
                   using the Virtual RAM.
                
                        To prevent from loss of data when power
                   off or system reset, remember to save the files 
                   in the RAM Disk to floppy disk or hard disk drive.

 

                b. Printer Buffer

                        Normally, the size of buffer in a printer is
                   several Kbytes only. If the printer is slow, you 
                   may waste a lot of time to wait for the completion
                   of printing whenever a large file is printed. By
                   this Printer Buffer, you can save about 90% of 
                   time in waiting for print. This frees you from
                   waiting and you can do another job.

                        The file  "CPRINTER.SYS" in this diskette 
                   is the device driver program of Printer Buffer. 
                   Which can handle both the LPT1 and LPT2 
                   simultaneous. Another program called "cp.com" 
                   is used to clear the Printer Buffer. Just 
                   type "cp" in the command line whenever you
                   want.
                   
                        

                c. Hard Disk Cache

                        This driver can speed up your hard disk 
                   about 4 times faster by storing recently used
                   disk data in the cache and pre-fetch data 
                   from the hard disk. Since DOS organize disk 
                   data in the unit of cluster (4 sectors) and
                   about 99% of requested data size is 1 sector,
                   the cache will read a whole cluster when the
                   requested sector is not stored in the cache.
                   
                        The Hard Disk Cache driver is called
                   "CCACHE.SYS". Another program "rate.com"
                   is used to check the hit rate of the cache.
                   When you want to inspect the hit rate, just 
                   type "rate" in the command line. 
                   
                        You no need to care about which hard
                   disk should be cached. All the hard disks 
                   will be handled automatically.
                 


                d. Change Mother Board's speed


                        The program "STURBO.COM" is used to change 
                   the speed of the mother Board, and to set the 
                   board's speed during disk access.


                   STURBO [switch]  [disk access speed control]

                   where  [switch] = ON    turbo mode  (high speed)
                                   = OFF   normal mode (low speed)
	                           = HARD  hard switch dependent
		
      [disk access speed control]  =  /t  :  high speed
	                           =  /n  :  low speed
	     

                   

                        Once the "STURBO.COM" is run. You can use 
                   keyboard to switch the speed of the board.


                   Press 'alt' 'ctl' '+' at the same time for high speed.

                   Press 'alt' 'ctl' '-' at the same time for low speed.

                   Press 'alt' 'ctl' '*' at the same time for hard
                                         switch dependent.

                   note :  The '+', '-', and '*' are the keys in
                           in the key pad.
