  99.  
  100.  
  101. 1.) Install the drive with the stripe on the 40 pin cable facing the 
  102. power connector. Use the user definable BIOS type to set up the 
  103. drive with 981 Cyls., 10 Hds., and 17 Sectors. No pre-comp and 
  104. no Landing Zone. This will format to 81 MBytes.
  105.  
  106. NOTE: If a user definable drive type is not available the other 
  107. acceptable parameters are 1024 Cyls., 9 Hds., and 17 sectors.
  108. This drive type will only format to 76.5 MBytes.
  109.  
  110. 2.) Boot the computer with your DOS boot disk. (at least 3.3 or higher)
  111.  
  112. 3.) Go into the "FDISK" program and set the partitions as required for your
  113. application.
  114.  
  115. 4.) High-Level Format your partitions i.e. "FORMAT C:/S". Repeat
  116. this for each of the partitions created.
  117.  
  118. 5.) The 7080A is now ready for use. This drive does not require nor do
  119. we recomend a Low-Level Format.
