| schestowitz[TR2] | firmware, not modifiable at all. The Tivo also contained a modified | Aug 27 07:57 |
| schestowitz[TR2] | version of Linux, modified with a malicious DRM functionality. The | Aug 27 07:57 |
| schestowitz[TR2] | firmware would verify that the running copy of Linux was the precise | Aug 27 07:57 |
| schestowitz[TR2] | binary that the company had shipped. As a result, it was impossible | Aug 27 07:57 |
| schestowitz[TR2] | to fix the DRM by installing a modified version of Linux -- the | Aug 27 07:57 |
| schestowitz[TR2] | firmware would detect that and turn off some functionality. | Aug 27 07:57 |
| schestowitz[TR2] | (DRM decoding, I think.) | Aug 27 07:57 |
| schestowitz[TR2] | The fix in GPLv3 was to require the binary to be accompanied by | Aug 27 07:57 |

| schestowitz[TR2] | GPLv3-covered program in the same hardware and have it fully | Aug 27 07:57 |
