Each controller board typically has 32-64 MB of cache, used when transferring data from the disks to the computer. We are looking to repurpose that cache memory as RAM aaccessible directly by the operating system. <br /> <br /> &#039;&#039;&#039;Current Status&#039;&#039;&#039;<br /> Currently we are following a similar project undertaken on [http://spritesmods.com/?art=hddhack&amp;page=1 sprites mods]. We have identified the JTAG pins on the controller board, we now need to solder these wires to the JTAG debugger for manual reprogramming. Updates to come soon.</div>
