can you tell me where exactly to read because I did read enough manuals and did many hours of hunting.  Many others will appreciate it.
You can't get more specific than this :
link> Bootable SD Card Method

I looked at the auto start script, but that didn't work as I wanted..  can someone tell me if it's possible to really press the on button or whatever button and get it automatically in hack mode without fussing with it?
Answer :  Yes.    Although you have to press the <ALT> key after the camera starts to switch into "hack mode".   The exact key used for that depends on the camera but its a one button press after you start the camera.   

Update :  in the sx40, I believe the <ALT> button is the "Print" button (to the upper left of the LCD display)

Thanks waterwingz, you might want to read my updated prior post just before your post.  Thanks!  I really appreciate it.  If you didn't post, I would have gotten it wrong again.  CHDK'd documentation is all over the place and this is just frustrating to no end.  I'll write back and you other newbies know.  The most common questions should be at the Quick Start guide .. Nobody would be able to find this link if you didn't write.

http://chdk.wikia.com/wiki/Prepare_your_SD_card#Bootable_SD_Card_Method

Again, thanks a lot.

Canon, you suck and you're too damn cheap to provide raw for sx40.  I'm going to post my experience on Amazon too so people will stay the hell away from Canon.  I shoot SLR too and there's some horrible things about canon.. one was their stupid option to "erase all" when you want to erase one picture only.  The erase all does not belong in the regular button menu, and frankly, shouldn't even be in the camera.  If there's naked pictures, then lot the erase be available by the PC.  That fix isn't hard to impliment in a firmware upgrade, but Canon refuse to fix the issue.  Too bad the Panasonic DMC-FZ150 cost a bit too much, otherwise, I would have gotten it.   The "erase all" that I'm complaining about is in regards to the Canon 20D.  They've lost a customer and I may well ebay this camera.  I got it for $270 at fry's electronics, new.  Why can't canon added a single chip that would have boosted quicker writes and put in raw mode too?  Canon was cheap, most probably they decided to forego this extra ram so because writing is slow, that's why they decided to forgo raw.  That must be the reason.  customers should not have to go the way of hacks just to find RAW capability!  I'll say it again, Canon, you're too cheap.

this is buried in the FAQ pile.  this sucks the way it's documented.. who would dig all the way that deep??  CHDK is worst than linux..it drives a person insane.  why can't this be in the short start up documentation and put it near the top?  This is a very common question everyone would have.  and for the record, my experience with CHDK has been really frustrating to say the least.
So can we assume you are volunteering to take on this project and produce such a short start-up document ?  You seem to think its important - time to give something back to the community maybe ?  Or would you prefer a full refund of everything you have paid for CHDK so far.

I'm just extremely pissed at the situation .. excuse the language but think about it.. I looked at the quick start document before, but i noticed half the pages are upside down.  Who's dumb idea is that??  Seriously, you ever find any document like that??  if you want to save paper, perhaps provide two version.  Also, that's not even a quick start.  if you want a quick start, I mean a REAL quick start.  this is what I mean.. and this stuff got to stop!  it drives me insane.  I'll go over the link you sent me and I'll write a real quick start that you can post on the web instead.  a quick start should not go in a pdf format cuz when I say "quick start" i mean, I need it quick and dirty style.  You know how many hours I've wasted on this stupid camera???

How many people even join the forum to figure this hack out?  Seriously, this is just intolerablely stupid, bad judgement or whatever you have, but dude, I'm just mad and totally frustrated at this point.  And how many people have wasted their days on this stuff?  It really adds up, and this is another reason why I am really hating canon.

Canon, you are cheap!  Can someone forward this message to Canon's CEO?  Heck, I'll do it.  I'll find their contact info and at least I'll do my part and email canon.  Heck, if someone is interested, perhaps start a petition at change.org and let the world know.  And I'll say it again - Canon, you are cheap and certainly don't have your customer's interest at heart.  I hope other companies eat you alive.

You do realize that CHDK is totally independent of Canon right ?   Not sanctioned, supported or aided in any way ?

I look forward to seeing your improved guide.

Before asking my question, let me just balance some of the comments here by expressing the following views as someone who stumbled upon chdk a couple of weeks ago.

Chdk is amazing and it makes my SX40 and other Canons much better cameras.  For my particular application, my SX40 is better than a DSLR and far better than any other other P&S, mostly thanks to chdk.

There is nothing wrong with the chdk documentation from my perspective.

Canon did what it did for good reasons and gave us a fine camera in the SX40; at the same time, it's great that chdk lets us circumvent some of what Canon did.

Now, my question.  This concerns the ND filter override.  I notice it is implemented in the SX40 build.  This suggests that the chdk developer found something in the firmware indicating that an ND filter really exists in this camera.  Is this known for certain?  Has the override been tested?  I get ambiguous results when using it (version i).  When the ND filter override is engaged in AUTO mode, I get underexposed images.  In P, Av, Tv, and M modes, it seems to make no difference at all, generating the same exposures with the same exposure settings.  Is there any relevant history relating to the SX30 build, with which people have more experience?

Thanks for the great work,

August

Of course, I know this forum is independent of Canon. :)  I'm really busy and haven't tried the auto load thing  yet, but when I do this week, I'll write a really quick and dirty startup guide.   Trust me, it'll be very short.  I apologize for being so upset with the situation, but you see what I went through.

August: "There is nothing wrong with the chdk documentation from my perspective."  I don't find your comment helpful at all.  I obviously found some huge problem with documentation, so you went and discount my reporting?  What's the point of this?  I also think many here would take issue when you say "Canon did what it did for good reasons and gave us a fine camera in the SX40."  I strongly disagree.  Canon did it for their self interest.  You can look at a video put out by the creators of Magic Lantern and you'll see why they also wrote a firmware.  People aren't happy with some glaring and annoying flaws, so I don't see why there's a need for you to defend any manufacturer.  It's like this, you found a problem with the ND feature, then do people go and say they don't have a problem with it (in fact, haven't even used it), and then point you to a pile of documentation?    :haha  anything un-necessary, don't say it.  The situation is already really inflamed.

Don't even get me started about Canon doing what they did for a good reason.  Yeah, then can you explain to me why it's such a good idea that Canon included the "erase all" pictures in one of their buttons on the 20d instead of to erase a single picture!  Imagine what professional wedding photographers felt back in the days.  I know personally a buddy of mine hit the wrong button.  And Canon still failed to update their firmware to fix that problem?  There's already a feature to format the CF card, so obviously, Canon did not think hard when they put in the stupid "erase all" feature.  Certainly, I don't think Canon put in that "erase all" as in hard erase to erase pictures I've taken of naked women!  Canon could have let people erase all the pictures via a PC and card reader.

I've detailed these problems about the documentation prior, so it is a problem for me and many other people:  a) absolutely necessary info is buried deep in the document, or shall I say, multiple documents.  And when I had a problem, I'm directed to search through a whole pile of documents until a nice soul pointed me to a specific area in one document, which I really appreciate.  b) one of the document is written in pdf format where half the pages are upside down.   ::)  Not everyone is interested in printing out the document.  Then you have some readers who are less computer savy and they'd be upset figuring out how to rotate the pages.  If anything, I'd make everything frustration free.

I believe what I write is very logical and reasonable.

Some statements add to the discussion, and some statements don't.

The documentation has many problems, and there is plenty of room for improvement. Contributions are  welcome. That said, it seems to me you are missing something fundamental: CHDK is hack.

Making simple, concise instructions that are easily followed by non-technical users is an admirable goal. It's also completely unrealistic, because using CHDK isn't simple or non-technical.

To be accurate, the documentation needs to cover a lot of technical details and corner cases. Even so, the behavior is simply not fully understood or well defined in many cases. I've been a CHDK developer for several years, but I still frequently find my self having to experiment and dig through code and firmware disassembly to figure out how a particular feature works. After doing that, my results are only valid for a few cameras, subtle and not-so-subtle variations between ports and models are common.
