          Modification History
          --------------------
          2003-Feb-17  - Base release
          2004-Jul-19  - Fix for panic when scatter/gather list exceeds 
			  maximum count (fz528544)


          To install the driver, follow these instructions:  
	  
          1. Acquire the driver from the ftp address given above.

             - Download the btld image to a directory/file on your machine,
               for example, /tmp/iir_btld.img.

             - Verify the downloaded image using sum:

                  sum -r /tmp/iir_btld.img

	       This should return:

	          10314  2880 iir_btld.img

             - Format a floppy disk using the format command.

             - Copy the downloaded image to the floppy:

                  dd if=/tmp/iir_btld.img of=/dev/fd0 bs=18k

             - Verify the copied floppy image using sum:

                  sum -r /dev/fd0    

	       This should return:

	          10314  2880 /dev/fd0
	  
          2a. Fresh Installation on Primary Drive

              - Insert a boot disk or Installation CD and boot the system.
    
              - At the boot prompt, type:
          
                   defbootstr link=iir

              - Press <Return> and continue with normal installation.  
	  
          2b. Installation on a Secondary Drive
            
              - Boot and Login normally.

              - Mount the floppy image:

                   mount -r /dev/fd0 /mnt

              - Use the BTLD Install script to install the driver:

                   /etc/btldinstall /mnt

          Once the kernel has been relinked, reboot the host and verify
          that the driver is initializing the card.
