How to bypass /Extra from Loading?

[MonkeyDLuffy]

Hi all,

Is there a way to bypass "/Extra" from loading at boot-up with a kernel flag?

The reason I want this is that I have installed Snow Leopard and Leopard in my external hdd.

This is how I configured my External HDD:

Partition 1 = 30gb Snow Leopard Installed and this is where /Extra is installed (Chameleon RC3 Installed)
Partition 2 = 30gb Leopard and there is no /Extra
Partition 3 = 20gb NTFS

I'm having problems booting in my Leopard partition because it loads the /Extra from the Snow Leopard partition. Of course, my Leopard will have errors from the Snow kext.

If it is not possible to bypass /Extra, what other methods do you suggest or any kernel flags to boot directly to the Leopard partition (2).

Thank you so much.

dude,

With RC 3, on your Extras folder create 2 folders one named 10.5, one named 10.6. On each of these folders, create a subfolder called Extensions. Copy all the appropriate kexts to the corresponding OS to these folders. Copy Leo kexts to 10.5/Extensions/, copy SL to 10.6/Extensions/. Thants it, it will know which system you are booting and load those particular kexts.

In the Extras folder, you should have your boot.plist, your dsdt.aml and smbios. You should also have your Themes folder here.

EDIT: Spoke too soon!  Almost fixed though I'll edit the whole message.

Thanks dude!  It is almost working.

However, I noticed some problems.

I noticed that the /Extra/10.5/Extensions doesn't load when booting to leopard.  The 10.6 loads properly when booting to snow.  I don't know why the 10.5 doesn't work.  I checked the spelling of the folders and they are ok.  I tried putting /Extra/Extensions and it is being loaded in 10.5.  The big problem with this is when booting in snow, it loads both "/Extra/Extensions" AND "/Extra/10.6/Extensions".  So I had to remove the /Extra/Extensions to boot to snow.

What could I be doing wrong?


The other problem is kinda big. I have two DSDT.aml - 1 for Snow, 1 for Leo.

Unfortunately, the dsdt.aml from Snow doesn't work in Leopard.  It kernel panics.  My dsdt.aml from Snow Leopard has the CMOS reset fix and I believe that is the culprit in the panic.  The one from Leopard works both in Snow and Leo, but if I boot to Snow using the dsdt from Leo, CMOS resets (as expected).

My next question is:

Is it possible to AUTO-load two separate dsdt.aml, located in 2 different folders?  I checked out the help file in RC3 and I read that you can pinpoint where the DSDT loads.

kernel flag

DSDT=path.

 I haven't tried it yet, but I need to know if there is a way to automatically load it.  I hate to type it every time.

Any suggestions would be greatly appreciated.

Thank you again! You've been a great help!

Use the same DSDT for both, just add the CMOS reset fix to your old DSDT manually. It should not cause a panic, something else is wrong I think. Try comparing both DSDTs in a text file comparing tool.

I can boot both OS fine with the same DSDT.

This only works if Chameleon is installed into EFI System Partition, if you installed it into a standard partition it will not work. /Extra/Extensions from the the system partition is read always and 10.5/10.6 (the one matching the OS version in the partition) ignored.

It will also work if Chameleon is installed to a separate partition.
