From my understanding there are roms that can be flashed to the nand memory (wiping out the stock b&n crap), roms that can be burned to the emmc, and roms that can be burned to and booted from an SD card.
Provided I understand that right, ideally I want to have Gingerbread installed on the emmc and possibly either Nookie or the modified Eclair rom on the rom memory..
Am I understanding this correctly? Is this setup possible? If this is possible, could you then burn a THIRD rom to an SD card and also boot from that?
There is a thread somewhere with a script to change boot priorities and allowing you to boot into any OS, but I just want to ensure I fully understand how this thing works before I go attempting to flash 3 OS versions lol
This Nook is just my toy, I bought it the day I saw the honeycomb port so I just want to play around with different rom setups till honeycomb is stable and ready to be flashed the nand memory.
Thanks for any help to further my understanding, it's greatly appreciated.
My understanding is there is no nand on the nook which makes sense.
Roms that flash to emmc actually replace the stock rom image.
There are only two ways to install roms: to internal flash memory (EMC) and external flash memory (SD), so the answer is "no".
However, it should be possible with modified uRamdisk (or u-boot so it would run different init/init.rc, which would mount different partitions/subdirs) to have multiple roms on a single SD card.
ah ok I see...so the there is no rom/nand memory and the stock rom is stored of the emmc? So at most you could have one rom on the emmc and one on the external SD?
That makes alot more sense. Thanks for clarifying guys. I'm about to flash Honeycomb to the emmc, wish me luck ha
now I realize I'll prolly get the lynch mob soon after i post this... being that all the research is over in the dev section, but my question is fairly complicated and i cant seem to find a direct answer from my own reading.
now i have root on my NC and i would love to put a custom recovery/rom on my NC. could any one point me in the right direction to get me started loading a custom recovery? i dont want to run froyo off of an SD card i would love to have it just be a giant version of my phone(I'm sorry if that's asking to much)
i learned and pushed myself to do it a while back on my EVO 4g when i saw there was a rom with wimax capability's and that was my first time rooting anything. I do on the other hand work as a sprint instore service and repair tech. so all of this reading isnt completely lost on me.
and my second question. when i booted my nook back up after i let the battery die, all my setting and apps were gone. any one know anything about it?
thank you for any answer, and I'm very sorry about my spelling and grammar, i know it sucks >.<
i think my biggest confusion/hangup so far has been the custom recovery not sure if i have this right or not but. these are the steps (i think) i need to take.
1. aquire root. [check]
2.custom recovery.[?]
3.custom kernel.[?]
4. custom rom.[?]
So what you want to do is flash a custom rom? You would just download a CWM sd card image. Burn that image to your SD card. Then, grab the rom you want, such as nookie-froyo, or whatever. Copy that zip to the SD card.
Put the SD card into your nook, then reboot. It should boot into CWR and from there you can just flash the zip. The same thing with a custom kernel, just copy the zip onto your CWM sd card, reboot, and flash the zip.
I'm not sure if that is what you are asking, though.
I've actually figured it all out finally. is there any way to see what my CPU is running at?
The speed of your NC can be done by downloading 2 free apps in the market:
Linpack for Android
Quadrant Standard
The Linpack app will tell you how many MFLOPS (Millions of Floating Point Operations Per Second) and Quadrant will give you a score to benchmark for CPU, I/O, and graphics. They will also give you as a reference how you compare to other devices.

So I'm new to Nook. In fact it's still being shipped for the wife, lol. Little that she knows, it's getting nootered before it even gets in her hands.
I've rooted phones and flashed custom ROMs.
From what you're saying above, does CWM reside solely on the SD card? That's different than a mobile phone. So any time we need to install a custom ROM (even the first time), we'd have to boot using the SD Card that has CWM, right? Of course I'd have to root the nook first.
following should really go into a different thread:
So whats the best ROM? So many out there. I just want to be able to use all google apps and market (for kindle app).
Thanks in advance.

You can still install Clockwork from the market and it'll run of the NC without an SD card. I've done it. But for the installation of CM7 (something to do with EXT4? I don't even know what that means...) CWM on an SD was necessary.
On what the best ROM is. Well, looking in the general section subsection here it looks like a lot of people are on rooted stock 1.1. I tried Froyo and it was cool and all, but I missed having the full 8GB of storage on the nook. I haven't tried Honeycomb yet, so no idea on that one. I currently have CM7 nightly 8 on my NC and really like it. I may not have all the storage space still (they're working on it) but it's snappy and sleek.
I would have posted this question on the developer board, but I am too much of a noob. I am wary that my question will sound like jibberish, but I am really confused about dual booting and the special files that are necessary.
I am using rooted 1.1 stock and have got it customized about as far as I can go. I want to run CM7, but the one app that keeps me tied to the Eclaire OS is the original B&N reader app that allows downloading of magazines and newspapers. From what I gather, the standard Market Nook app does not allow magazines and newspapers to be downloaded. I saw that some on this board are trying to port the original stock reader to Froyo and CM7, but they are not there yet.
Because I want to keep 1.1 and still try out CM7, I am looking to either boot CM7 off an SD card or dual boot 1.1 and CM7 in eMMC. I have yet to see a solution for booting CM7 off SD, so I have turned my attention to dual booting.
There are threads and files on the development board that allow for dual booting, but I can't quite figure them out. If possible, I would like to have the current 1.1 placed in the "alternative" partition (Power+n) and CM7 in the main partition (Power). Here are my questions:
Can I dual boot my existing 1.1 and the latest version of CM7 (14)?
Can I do this without any specially modded ROMs?
Does running the partitioning program destroy the existing 1.1 setup?
There is also a "script" to move the current setup to the new partition. Does that mean that my exising 1.1 setup will be left intact after the partitioning and can be moved without any alteration?
If so, do I need a special version of CM7 or will it automatially flash to the proper partition?
Assuming this is all possible, how do I use adb with all of the partitions?
And lastly, is CWM still usable in this type of arrangement?
I am sorry for all of these questions and I hope they kind of make sense. Thanks very much in advance for any help.
All good questions. I can only answer number 3. the partitioning zip will not destroy the BN install. Just makes the free space on the emmc smaller. Well it does more then that, but that is what you'll notice when using the BN install. I successfully used it to dual boot with HC. There is a bug with CWM 3005 that you'll run into if you follow the HC dual boot instructions from addictivetips. Use CWM 3010 or look for the shell script you have to ADB onto the CWM to allow CWM 3005 work with the dual boot script.
I'd love the answers to the other questions as well.
This is the fastest and easiest way I found to Dual Boot. Works flawlessly.

I bought the original Nook Color back in Nov. 2010. I went through all the methods back in the day, when guys first started rooting the Nook and all the problems we had back then ... side loading apps ... adhoc issues ... B&N updates ect ... we got CWM recoveries and finally we got fully working froyo's and Gingerbread's. Then CM7's and the Phiredrop's.
I been through it all. I ended up giving my Nook to my son, and he loved it. I got into Android Development Cell (ROMS). I Now got my Nook back from my son. It is working, but I have forgotten a lot about how to mod it .... mainly the partition tables, and how the bootloader runs. Does it look to the eMMC first ? or the SD-Card ? Can we flash from both locations ?
Anyways ... He has it setup weird now. It has a dual boot menu, I can boot into CM7 or CM9, But it is acting up and some stuff doesn't work. He also says it can boot into Stock 1.4.2 somehow *shrug*
I have done some searching here on xda but it is a lot of OLD posts and dead links.
Could you guys help me out with a few questions ?
01) I would like to wipe EVERYTHING from eMMC abd SD-Card and start over. I know I can format the uSD and also format the eMMC, but Can I flash a SD with a CWM image and then install Stock 1.4.2 on the eMMC. Do I even need to install stock first ? What is the best method for this ?
02) Will I need to nooter my nook again at this point if I do that ?
03) Can I run CWM on the SD and run a nandroid backup to that same SD if it is a large SD-Card ? I thought I could since the bootloader looks at uSD first (but I guess it looks at the boot partition huh ? ) my son says NO you can not run CWM and have a nandroid backup on that same SD. Yes or No ?
Bottom line is this is what I’m trying to do……
01a) I could care less about stock B&N.
02a) I just want a Nook that will dual boot into CM7 and / or CM9 preferably from my 16 GIG SD-Card but it really doesn’t matter, as long as I can install app’s to the external SD-Card.
03a) I want a way to backup the entire CM7 or CM9 via CWM to my SD-Card.
NOTE: I have a (1) 16 GIG SD-Card (1) 4 GIG SD-Card and (1) 8 GIG SD-Card.
If you could help me out with any info at all on any of this, please do so. I am mostly Android literate and I have a working ADB on my win7. I just have forgotten exactly how the nook operates at the lowest level, and how the newer CM's are flashed now after a clean format
Thank you for your time and help to any of my questions.

The Nook Color boots from uSD first... then eMMC if there is no bootable uSD in the card slot.

Yes.... I do that frequently.. the thing is... the nandroid backup will be of the eMMC unless you use one of the modified CWM's designed for SD installs.
Additionally... if you are going to run that from a uSD with another ROM on it... you will certainly have to adjust the boot partition on the uSD to be large enough to hold the nandroid you are creating.

So you are saying that I can do it in this order:
1) Format eMMC ( only boot partition right ? )
2) Format uSD ( resize boot partition to a larger size for backups )
3) Create bootable CWM uSB ( any particular one you recommend ? )
4) Put one of the stocks 1.4.x files on the uSB then flash it
5) Put CM7 or CM9 on uSB and flash it
Question: Do I need to flash stock 1.4.x even tho I dont want it ? or can I skip step #4 ?
Thanks

Item 1) highly NOT recommended. There is no point to format /boot.
Item 2) if "uSD" means the external microSD card, then, no, you don't need to format it since it will be done in step 3 of your list.
Item 3) Get the CwMR version 3.2.0.1. And call it "flashable CwMR uSD", not uSB.
Item 4) If you don't want stock, leave it out as no point to touch it.
Item 5) After done step 3 above, put CM7 OR CM9 in there, the CwMR uSD, and flash.
Strongly suggestion: before doing anything. Be sure you know what you trying to do or at least, pls let us know what you try to accomplish. For example, do you try to run CM7 or CM9? Do you want to run it from the external uSD card or from eMMC? Instructions are different.

Hello -
Thank you for the update info. Glad I asked first. Thank you Dizzy for your help, you have been a big help to me in the past also. Votinh thank you for your reply. Looking back at what I wrote I see many mistakes in my process. Thanks for correcting them.
Now ... as to your question Votinh. What is it I am trying to do.
First off this is what I currently have. Nook is working, but not well and just a mess in general. Sometimes it locks up or just runs at a crawl. ( I have CPU oc'd to 1200 ) I have CM7 and CM9 but can't seem to boot into CM9 anymore at all. I also have CWM v3.2.0.1 installed on my external SD-Card with a nandroid backup.
I just want to erase it all and start over : )
I want my Nook to be able to Dual Boot into CM7 and CM9. I would like both CM9 and CM7 on my 16 GiG SD-Card, BUT if that is not easy or possible then I would like CM7 on internal and CM9 on external. I dont need stock.
If all else fails ... or just to complicated I could live with just CM9 (nightlies or stable) with all APPS installed to external SD. and forget about dual boot.
Again thank you .... and please ask me any more questions you might need to help clarify my goal.
Peace

So far, everything you've asked are doable, in fact, a lot of members currently having the same system you describe.
Firstly, "I would like both CM9 and CM7 on my 16 GiG SD-Card" is called "dual-boot, it is a true dual-boot.
Go thank "racks11479" for his tremendous work
Link: http://forum.xda-developers.com/showthread.php?t=1448186
Note: both CM7 AND CM9 are on the external uSD card.
Secondly, "then I would like CM7 on internal and CM9 on external."; since your wish is granted , this is just an option for you. Yes, you can easily install CM7 in eMMC (aka internal memory) and booting CM9 off uSD as you want.
For references:

In bold: sure, but what do you try to do? Format the internal so that you can install something else on it?
I currently have CM7.2-RC1 Kang running on eMMC, it is really good.
Booting off uSD is more like for experimental, play it for a while to see if we like it or not. For trying, I recommend using uSD.
I have not spent more time on CM9 since I don't see much of the benefit of it.
Also, MisRy covered pretty well there.

Thanks for the info Misry. I have many sd cards and have used them all will good results. My Sandisk is only 4 gig ... so it was not going to be my first choice. I also have a Class 4 8 Gig Kinston I was thinking of using. Or a Class 10 16 Gig Patriot, which I know people dont like, but it seems to work fine in my phones ....?
Magus-
The difference in the SD card class as far as speed comes down to the size of the information we want to write. The lower classes aren't very fast with the large hunks of info, but excel with the tiny byte exchange used in the ROM. As the speed of your system will really be affected by the slow I/O rates of something like a class 10, compromise on size before class. It may be counter intuitive, but people have given up on cyanogen in general only because they had the wrong sdcard. This is especially true if you have a dual boot and are running the ROM off of the sdcard itself.
Look at the "strange results or how I learned to love cm" or something thread. Google that with xda and nook and you'll find it. That has all the info you'd want and way more.
Do another book with Eddie Campbell and we'll call it square. You know you want to.

Well I was testing a homemade script and I believe I did in fact format eMMC and either scrambled the boot partition or deleted it also on emmc. No mater what I do I can not get eMMC to boot. I can boot cwm from SD-card, but nothing on eMMC.
Advice ?? please be as technical as needed. I do not have Linux right now, but I do have adb on win7 and 3 sd-cards
THanks
Well, let's see what we're working with...
$ su
# fdisk -l /dev/block/mmcblk0
Post the output of the above. It'll show what partitions are left (if any) and then we can take it from there. This can be a hassle indeed, and it will require some research as I have avoided doing this myself. I am hoping your ROM partition is still intact, at least.
Anybody else who can help, please do. I may not be able to respond as often as I would like.
I was gonna suggest 8+1 to see if we can get back to square one.
http://nookdevs.com/NookColor/RestoreToStock
He's gonna need a ROM partition for that to work.
For a long time, 8 failed boots would (as a last resort) result in a working Nook for just about every problem. But, as users are getting more experienced across the board, more advanced and dangerous stuff is being attempted.
When everything goes right, it can be pretty rewarding, but when it goes wrong...well, let's just say the solutions become a lot more advanced as well.
The output of the command will let us know which partitions are erased and if any are still intact. Considering the information we have so far, I am not hopeful. If the emmc was erased and formatted...well, we'll see.
Here's what has occoured:
over-wrote the following partitions with "0":
# 0p7 = /cache
# 0p1 = /boot
# 0p5 = /system
# 0p6 = /data
Then formatted 5-7 ext4. Flashing a ROM with a blank boot partition has been done on another device many times with no issues, for some odd reason this nook responded poorly and I believe the the boot.img never copied over to 0p1.
I am not sure what all he tried but I know he tried the flashable emmc fixer, which didnt' fix it. I am actually concerned that made it worse, but that's my opinion and I don't have my hands on the device. For what ever reason he couldn't get adb working with the device. I found this thread:
http://forum.xda-developers.com/showthread.php?t=919353
And since ADB wouldn't work, I wrote a script and created a flashable zip for him so it would perform the same operation, but it stopped saying bad zip. He tested it with 7zip and there were no errors, I checked my script and I see no errors in it and yes, I used a proper program for it as well, NotePad++. He's a bit frustrated and sending it to me. I am confident that if none of the things he tried didn't completely scramble the internal partitions that I can get it working. But if anyone has any idea as to why the script would fail, let me know.
Edit: And correct me if I am wrong, but it's the lack of a kernel which caused it to respond so badly. A similar thing happened on our phone but was due to powering off with a blank boot partition (not our noob moment but someone else's), but being that it's a tegra 2 system we have Nvflash and all is easily rectified. My theory is that there's something, most likely memory, which is loaded by the kernel and is required for a recovery to run.
He tried the 8 failed boot and it did bring up something which ended with an error about no boot partition, I'll try to get the picture he showed me later, I need to run off to work right now.
... Nevermind

First, why in heaven's name would you purposely want to write zeros on the boot partition?
Second, adb was not working because there was no kernel or ramdisk on the boot partition since you had him zero it out. Adb needs both.
If he was trying to flash your zip with CWM from a bootable SD card, then the zip needs to be properly signed before CWM will flash it. You can have CWM toggle off that check, but I doubt he did that. Hence the bad zip error.
Also if he has his CM7 SD card still working, he can repair the emmc partitions using the terminal emulator from CM7. All the adb type commands can be run from there.
The boot partition probably needs to be reformated to vfat before it can accept any files from a CWM restore.
THANK YOU IN ADVANCE FOR ANY HELP! I'm dead new with android and just got a Nook HD+ 32gb (groupon deal $130)
anyway, I've done a ton of reading on here and watched a bunch of youtube vids- i don't know if people use overlapping terminology that means the same things or what.. and also seems like theres a lot of opinions in the forums.
I want basically the full android experience and root access- like i said, never used any android, but i like toying around with these things. BUT i also really want a fully stable platform- don't want constant crashing or it reseting on me.
questions i have-
1)the CWM is the "program" (don't know the correct terminology) that basically gives me the access to back up and install new roms, root, etc? TWRP does the same thing- but i understand you don't use that?
2)If i have a BRAND NEW nook HD+ do i need to back it up before messing with it OR are the "stock rom" zips you provided just that?
2) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?
2a) What problems am i going to run into using my mac to make the SD card, if any? what program do i need to use?
4) when you back up through CWM where does it save it? to the SD card?
4a) this is where i was confused about the image, reading into some of the posts it led me to think the image file took up the entirety of the
SD card.
4b)So in the future i could just boot from the SD card and would have the option to flash the stock rom back on the HD+ if desired? and/or
go back to CM?
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.
7)what is this "trim" lag problem? couldn't really figure out what people were talking about.
thanks a ton for any help you can give me- I'm sure you receive a lot of questions!

CWM (ClockworkMod) is a recovery program that allows you to do just what you said. TWRP is also a recovery, but uses the touch screen instead of hardware keys to control it.

You can either use the CWM backup tool to return your device to stock (including any data you have already created, like registration) or the plain stock zips I have will also return you to stock, but the way it was when you got it new before registering.
3) with the SD card image, do i need to put a specific image on the specified sd card. i.e. 4gb SD gets a 4gb image? or is the image universal to whatever size SD card i get?

Since you have a Mac, the best way to do it is the new procedure without burning an image. Since I don't have a Mac, I don't know the exact programs to use. I think SDFormatter comes in a Mac version. And I know there are lots of mac partitioning programs to set the first partition active. And using the procedure does use all of the SD, so it is best to use a relatively small one, 2-4GB.

It saves it either to the SD card or internal memory, you choose.
Yes it uses all of the SD if you use the new procedure. But you need that if you choose to backup to SD. A backup takes about 1.5GB.
And yes, save the SD for future use, like restoring backups or installing new ROMs.
5) what is DUALBOOTING? and NANDROID? how do they tie into CWM and CM10. very confused about this.

Dual booting means having one operating system on internal memory (also called emmc for Embedded MultiMedia Card) and one installed to a bootable SD. Most people that dual boot have stock on internal and CM on SD. They are separate and independent from each other.
Nandroid just means internal memory. So a nandroid backup means backing up whatever you have on internal memory.
6) any disadvantage to flashing the EMMC vs booting from SD card every time? I THINK i want to flash the emmc, i don't want to be tied to booting from the SD card everytime- if I'm understanding that correctly.

The only advantage to booting to CM on SD is it leaves internal memory untouched for warranty reasons. The disadvantage is it runs slower and is less stable.

LAG is a complex issue to explain. If you are used to hard drives getting fragmented and slowing down your system, LAG is similar but a different mechanism with solid state flash drives. TRIM is a process to undo what causes LAG. But some of the solid state chips in these devices have a bug and when TRIM is run, it bricks the chip, making it unusable.
