Importing the base OS

[Joy]

I have a .cdr image of a base OS install that I’m trying to import into instadmg. I’ve tried mounting it on the desktop, but it fails. Does the base OS import have to be from the original DVD that you physically insert into the computer?

You can do it two ways. In the InstaDMG/Addons/InstaUp2Date/ Folder there is importDisk.py file. Just put the Original retail OS X Installer DVD in the drive and type ./importDisk.py –automatic –legacy and it will rip the disc.

Alternatively, you can put the OS Install DVD in and open disc utility, select the DVD and click new image. It sounds like you already did this for the Install DVD and have a .cdr file. You should be able to just make the file extension .dmg instead of .cdr and throw it in the BaseOS folder.

Do I have to run a checksum on the base dmg? I moved the .cdr to the base of folder and put the .dmg on the end and it is giving me a “unable to get checksum for image …..

It will checksum it automatically. It needs to be ‘Mac OS X Install DVD.dmg’ you don’t want ‘Mac OS X Install DVD.cdr.dmg’

If it is not checksumming properly, you could always try importing it using importDisk.py. Just move the file you have in BaseOS out and then run the python script. It’ll place it in BaseOS for you.

Where is the world did you get a .cdr image? In any case, if you need to use this one, then your best bet is to convert it to a main-line .dmg file. For sanity reasons I have put in the check you are running into to track what base disk image is in use, and we are going to be going farther in that direction later, so it is a good idea to get lined up for that (most people should not have to worry about this, you are in a weird case).

Assuming that this is a .cdr that hdiutil can recognize (you are hosed otherwise), you can use a command line this to convert it:
[code]hdiutil convert /path/to/image.cdr -format UDBZ -o ‘Mac OS X Install DVD.dmg'[/code]

I do want to sound the note of caution here: the .cdr format is a really strange bit. It makes me think that there is something odd going on here, namely that it is a “hackintosh” image (they are the only ones using that format… for whatever reason). I would be really leery of trying anything involvine “hackintosh” images with InstaDMG. There are real chances that you are not going to get what you expect, no matter what it is you are trying to do.

When you make a new image of a DVD/CD in Disk Utility and specify a ‘Image Format’ of ‘DVD/CD Master’ it spits out a .cdr file by default. I normally rip it as DVD/CD Master and then just change the extension to .dmg (Because it really IS a dmg, but it makes it a cdr for some reason…)

I’m not doing anything illegal or hacking anything over here. A colleague tried to image a new imac with an image I had created, and it is missing some drivers. So I asked him to put the image up on a file server and I would make a new one for the iMac. I thought it would be easier and quicker then having him trudge all the way across the campus, just to deliver the DVD to me.

I was apparently wrong.

I will try the conversion and see if that works. If not, I will have to break the bad news to him and have him trudge it over to me.

Larkost,

Did you mean to say “UDZO” compression in the command (above)?

UDBZ is too slow.

Also, your own ripper (importDisk.py) rips using “zlib” compression (not bzip2 compression). The compression you mentioned (above) must be a typo.
