This newly updated version of InstantCake for your Series1 DirecTV TiVo unit includes LBA48 support, large swap, and has been tested to run on single drives as large as 500GB. InstantCake will build the equivalent of our NetReady replacement drive kits -- this means you can purchase a TurboNet or CacheCard separately (available from 9thTee) and do the software configuration yourself without reinstalling the drive in a PC. NetReady replacement drive kits come with the latest TurboNet and CacheCard drivers pre-installed, and FTP access; by creating the file .NETREADY in your /var partition, you can unlock telnet access as well and the world becomes your oyster for installation of additional hacks.
