1) Yes, on DTivo it will.

2) I think it is a planned feature, I've not loaded anything from CVS in a while so I'm not sure.

Thanks for the reply. So, as for Question #1: If I have just a "basic" Tivo using RF in from Cable TV, the v2.5 upgrade should not effect me. Correct?

Okay, I too have super stupid newbie questions. I presently do NOT own a TIVO nor have I got a great deal of Linux experience - I can load it and get around however.

Is there a "step by step" guide anywhere that would help? I'm interested in purchasing a TIVO, upgrading it (there are guides), hooking it to my network, pulling streams off of it, compressing them, burning them onto VCD. This would be as opposed to using the hated VCR. I'm only interested in things like TV shows etc. That I could edit commercials out of and then archive the shows. I'd like to do this as much in Windows as possible (sorry Linux guys, it's what I'm used to).

I understand the TIVO runs a flavor of Linux but I'm looking for guidance on a TIVO purchase, and then guiance on how best to hack it so that shows can be pulled off for archiving in a somewhat simple fashion. Is the software to that point yet or is there still a great deal of tinkering? IF I ould get the stream off I don't mind fiddling with CD-RW until I got it right.

Anyway, some guidance or a pointer to a guide would help a grea deal. I know some of this is probably on the Underground but I also know that alot of it is also taboo (sigh). :confused:

The method they have used to stop modification of the system is trivial to disable. Well, trivial assuming some knowledge of linux. They've just upped the ante to a point where it will weed out some of the less enthusiastic/less knowledgeable. No more chmod -i, etc.

While I'm sure specifics will come around when 2.5 is official, I'll hint: The method they use is a standard linux process called initrd (Initial Ram Disk) which uses a small disk image and can be modified fairly simply. Check out http://www.linuxhq.com/kernel/v2.0/doc/initrd.txt.html and hit Google some.

I wouldn't suggest that people currently running 2.5 on their DirecTiVo do anything however - this is a beta test after all. Don't need to flood TiVo with user caused errors or throw it in their face that it's an insufficiant method.

Well Mark, unfortunalty it's not as simple or trivial as you think. The initrd image is located in the kernel partition and is loaded by the prom on bootup. The bad part is that the prom hashes the kernel partiton and checks it against a sig file before loading it. If the kernel partition does not match the sig then it will not boot. So until someone finds a way to generate these sig files or disable the checking in the prom, there is no way around it.

Is this 2.5 upgrade going to kill Hard drive mods? I'd hate to lose my 100 extra hours with the new version! TiVo was practically unusable at 14hrs.

The only thing it is harming is the TivoNet on DTivo's and the ability to get a shell from the serial port. If you have a SA Tivo, no worries, the ramdisk checking is not enabled with the prom that is currectly in the SA Tivo's. Not to say that that won't change in the future, but for now your safe. Any space upgrades that were made to DTivo's with the 2.0.1 or earlier software will not be affected either.
