Advertisements It's been a while since I last did this, so please forgive me. I'm trying to run SApper on the drive from a TiVo HD 652 unit. I apparently created a boot CD about four years ago and used it on another 652 of mine. When the disc boots, it IDs itself as a "PTVUpgrade LBA46 Support Utility Disk version 4.04DD." I can do an ls-l and see a number of directories (listed as etc/, bin/, mfs-tools-2.0/ etc.) but no files in the root. If I look at the disc in Windows 7, I can see the files I want to run (tweak.sh, sapper, rbautch_files.tgz, CUSTOM_KERNELS directory, etc.) but I don't see the same directories I see when booting under Linux. Does anyone even know what I'm talking about (I feel like I'm missing something I should know here) and how I can boot from this disc to run the programs against the TiVo hard drive?
