            NAME 

            AddBuffers - Increase the sector cache for system 
        disk drives.

            SYNOPSIS

            AddBuffers DRIVE/A BUFFERS/A D2 B2 D3 B3 D4 B4

            DESCRIPTION

            This command increases the number of disk buffers 
        used by the system for disk drive access. By increasing 
        the number of buffers, you can reduce disk access time at 
        the cost of losing memory to the sector cache (exactly 
        512 kilo-bytes per buffer). The buffers specified are 
        used for a specific drive, and do not affect the 
        performance of the other drives in the system.

            Commodore recommends not using more than 25-30 
        buffers with the standard filesystem, because more than 
        this does not improve system performance by much.  With 
        the new FastFileSystem (and a hard drive), more buffers 
        may increase performance, so more than 30 may be used to 
        good effect if you have the memory.

            Starting with version 1.3 of AddBuffers allows you to 
        set buffers for up to four disk drives with a single 
        command line.

            The default number of buffers are 5 for floppy and 30 
        for hard drives.

            Those formatting using the Fast File System (2.x and 
        above) will always benefit from more disk buffers. More 
        likely than not, the buffers are allocated during the 
        partitioning, and it is stored in the Rigid Disk Blocks 
        (RDB).

            With buffer space more information will be read from 
        the disk into memory, thereby making disk searches and 
        transfers much quicker. So, you are sacrificing memory 
        for programs in exchange for quicker disk access.


            For 2.x and 3.x ONLY: You can use this command to 
        find out how many buffers are assigned to a drive. You 
        can also subtract buffers to free up some memory.



            EXAMPLE
          1. To add 15 buffers to the sector cache for drive df0 
        do:

             AddBuffers DF0: 15

          2. To add 10 more buffers to df0:, and 20 to hard drive 
        dh0:

             AddBuffers DF0: 10 dh0: 20



		   For 2.x and 3.x ONLY:
          3. To subtract 10 buffers from df0:, and 20 to hard 
        drive dh0:

		     AddBuffers DF0: -10 dh0: -20

          4. To Return the numbers of buffers assigned to df0:

			 AddBuffers DF0:
