[Siyah Kernel] Can I dual boot an ICS ROM and a JB ROM?

Title said it. I want to try out the new CM10 builds for the S2, but I still want to keep my stable CM9+Siyah build running in case the new ROM has some problems. Went to the Siyah kernel dual boot guide thread, and it's stated there that one can only dual boot 2 ICS ROMs. That means no ICS+GB... but is ICS+JB possible?
By the way, yes I did do a search before asking and found this thread http://forum.xda-developers.com/showthread.php?t=1800866 where a method is proposed, but it requires switching to another kernel and I'd like to stick to Siyah.
Current configuration: CM9 RC2, Siyah v3.4.

[Q] Dual booting two different Custom Roms GT-i9300?

I tried today Dualbooting Omega v27.1 as primary Rom and ParanoidAndroid JB as secondary rom and it worked perfectly.
Now i tried the same primary rom (Omega v27.1) and HyperGalaxy,Hyperlight,and some other small lite rom,none of them worked instead Blackscreen loop.
So my question is ; can i Dual Boot my Omega v27.1 with foxhound or Wanamlite or any other custom Rom,or this is just incompatibility of Updater Script from EveryRom??

gb? you mean ics roms! there is no gingerbrad rom for s3
and yes. newest release of shiya are only compatible with jelly bean rom's. it's better way to copy 1st rom to 2 rom directory by using the shiya 2nd boot utils an flash the other rom as first rom using normal recovery.
must flash shiya again after flash of any romwithout shiya included!

No. Siyah is just a kernel. You can flash that without a doubt, as long as your Rom is supported by the kernel. But you should be fine I mean, I'm running it on MIUI ICS . Normally that should have bricked it ^^

As mentioned, Siyah is a kernel, not a rom. You can flash any kernel and keep your rom, as long as it is supported. Siyah currently supports anything besides the new leaked 4.2.1 roms which have different drivers. Hence you will be fine. In case you face some trouble you also can simply flash back your stock kernel (you can find most kernels in Perka's Stash).

Help understanding.

hey guys.
I've got a few questions regarding my i9100's kernels and ROMs.
I'm currently running dual boot RR Rom in primary on dorimanx v7.8 kernel, the kernel got updated to v7.8 when i installed M1UI ROM in the secondary ROM space. Both ROMs are 4.1.2.
I've tried to install the latest stable version of root box and paranoid android into 2nd ROM position. When installing them via cwm recovery I didn't get the launcher like with M1UI or RR, so there was no option to upgrade the kernel.
Paranoid android didn't boot at all after install and root box booted but the start animation was laggy when booting and once booted the system UI crashed with everything else. Both ROMs are jellybean and dorimanx v7.8 supports jellybean?
I'm guessing I'm missing a obvious compatibility issue.
My question lays with updating the kernel. Is there a proper way to update the kernel so I can try paranoid android and root box?
Should I clean/wipe both ROMs and caches, run a kernel cleaning script and install a new kernel (the latest version of dorimanx)? Then my current ROM will be incompatible?
Do I just got ahead and install a compatible rom (root box / paranoid android)?
Is this the right way to go about updating kernel to try new ROMs?
I haven't been able to find a guide on this subject. Leaving me with a small fear of fiddling with things I don't fully understand. If someone could point me in the right direction that would be great.
Many thanks.

For the latest root box and pa to work you need say dormanx 8.xx. Do clean your system up with kernel nuke and rom nuke then flash rootbox 4.2.2rom to first rom then pa 4.3 rom to 2nd rom. I say 8.xx cuz if you want to use a stock based rom you will need 8.xx as this is for both stock and custom rom. 9.xx is just for custom. By all means if your going to run just custom the use 9.xx

So once I've nuked ROM and kernel do I just go ahead and run rootbox.zip or do I flash dormanx 8.xx first?
I'm guessing I have to install dormanx first as its not included In root box?
How do you classify stock based ROMs and custom ROMs?
There are currently 3 versions of this kernel depending on your ROM type and firmware. v7 = ICS, v8 = JB/ICS STOCK,*** v9 = JB CM/AOKP ONLY

PA is based from cm, aokp. cm and aokp are based on stock ROMs?

Flash rootbox then flash dormanx then reboot. Set up rootbox then bk into dormanx cwm an flash 2nd rom. Forget about dori 7.xx as it's old and out dated. That's for ics custom jb rom. Stock firmware is any thing that uses the stock base. If you want to run jb stock based rom it needs to be a modded for dual booting stock based rom.
Cm aokp pa custom roms
Ics jb firmware is stock rom
I9100/I9300
OK, I'm not planning on using any stock ROMs, as I don't like the Sammy stock ROMs. So I'll flash 9.xx?
RR, CM, PA, ROOTBOX. all custom ROMs?
If they ain't the phones stock ROM then its a custom ROM? Regardless if its based on stock android.
Sent from my GT-P5100 using xda app-developers app
So if you gonna use custom yes just use 9.xx
Cm aokp pa are custom roms.
Hybrid rom like alliance which is custom stock rom. Uses stock base but has aokp type features uses dormanx 8.xx to run. You need to read more about roms mate.

Thanks a lot Andrew. Appreciate you time and help.

One more question, haha sorry.
When I do kernel and ROM clean. Which order is best?
ROM clean - install ROM - kernel clean - install kernel
ROM clean - kernel clean - ROM install - kernel install
I'm guessing because I am cleaning and installing everything without booting in between it doesn't matter?
Sent from my GT-P5100 using xda app-developers app
Rom cleaning script then flash rom
Reboot.
Bk to recovery then kernel cleaning script then flash kernel.
Reboot.

Thanks. Give it a bash when I get home.

Dual boot ics and jb possible?

Hi can you dual boot 2 different os versions.
Currently using neat rom lite and philz kernel
Read this
http://technopyrate.blogspot.co.uk/2013/08/guidedual-boot-jelly-bean-and-ics-roms.html?m=1
I think this article was published before Samsung released jb 4.1.2 with preload filled with bloat. To be able to dual boot 4.1.2 you need a modified rom and dorimanx kernel.
Dori 8 will only run jb so iCS will not work.
Dori 7.5 was the last version to run ics and it could also handle jb.
I have some vague memory of running neatrom ics with some modded jb rom as second( mayhap chameleon 3.01) with this kernel. The question is : would neat rom xwlpy 3.4 as first and neatrom xwlsz5 (jb modified) as second work together?
Has anybody tried?
Will report back if I try.
