Will migration assistant import my previous boot ROM version?

Hi. I've been reading these forums for a long time...first time posting.
I have a MacBook 5,2. It came with OS X 10.5. As far as I know, the latest boot ROM for 10.5 on a Macbook 5,2 is MB52.0088.B05 (EFI 1.4) (see http://support.apple.com/kb/HT1237).
A while ago, a friend convinced me to update to 10.6. Apparently, with the 10.6 install, it updated the boot ROM version to MB52.0088.B06. Now, I'm concerned that there is a firmware issue (which I might be wrong about, and the reason I think there is a firmware problem is very convoluted but I'll explain if you want). So I decided I wanted to go back to MB52.0088.B05. I had been thinking about going back to OS X 10.5 anyway. So, I backed up my system using Time Machine to a Time Capsule via ethernet. Then I did an Erase and Install with the original 10.5 install disc that came with my Macbook. Then, I used Migration Assistant to restore most of my system from the backup. I should have taken a look at the boot ROM version before I ran Migration Assistant...but I didnt.
The boot ROM version still says MB52.0088.B06.
I tried downloading the MB52.0088.B05 update and running it anyway, and it says my computer doesn't need the update. When I was still running 10.6, I did try the method described here: http://pubmem.wordpress.com/2011/04/09/flash-efi-firmware-update-manually-on-a-m acbook-51/ (which has apparently worked for someone else on a 5,2; see https://discussions.apple.com/thread/3747472?start=0&tstart=0), and it didn't work. I don't know if it's a good idea to try it again now.
So:
Why didn't my boot ROM go back to MB52.0088.B05 after a clean 10.5 install?
Did Migration Assistant import the previous boot ROM somehow?
Should I do another clean install without MA?
Should I try PubMem's manual method again?
Is there another way I can flack back the firmware?
Thanks a ton!
P.S. I posted this in the MacBook community as well. Don't get mad, I'm new. If that's against the rules, I'll take this one down.

Boot ROMs are firmware. Migration Assistant doesn't transfer firmware. Once you update firmware it can't go back to some previous version on its own. You would need to manually reprogram the ROMs with the old firmware.

How can I go back to a previous boot ROM version?

Hi. I've been reading these forums for a long time...first time posting.
The short story: I have a Macbook 5,2 running OS X 10.5 with boot ROM MB52.0088.B06, and I'd like to know how to flash the boot ROM version back to MB52.0088.B05.

At least you have made some progress. My inkling is the optical drive is dead.
I think you're right.
To run the AHT you would need the AHT disc that came with the computer, but it's unlikely you have it for that old iBook G4.
I do have it, in fact! But it's not working. Here's the situation, copied from a conversation with Kenichi Watanabe over in iMacs...
I haven't been able to run the Apple Hardware Test. I have the AHT CD that came with the computer (v1.2), and I also downloaded v1.2.6 here and burned that to a CD. In both cases, when I load the CD into the external optical drive which is connected via a firewire cable (exactly what I used for the install disc), restart, and press and hold C, the computer ignores the CD completely and boots from the HD. Any idea how to fix this? Or, is there another function I can use to achieve the same thing, maybe in single user mode?
Regarding the Apple Hardware Test CD, holding down the C key will attempt to boot from the internal optical drive. Since there is nothing in there, it boots from the internal hard drive. I would try starting up with the Option key held down. That should get you to the Startup Manager screen. If that CD is in the external FireWire drive, it should be listed as a startup disk choice. Select it and see if it will start up from it.
Right, that makes sense. Unfortunately, in both cases, when I select the CD to start up from, the screen blinks for a second and then returns to the screen where I am supposed to choose a startup disc. It does this as many times as I try to choose the CD, until I select the HD and start up from there.
When I put either CD in the drive, with the computer on and booted from the HD, the CD mounts, and Disk Utility says it's verified. But when I try to select it as a startup disc from system preferences, it doesn't show up. Ideas??
Update: I tried Hoja's reccommendation from this thread using Open Firmware, but in response to
boot cd:\diags
It says:
can't OPEN: cd:\diags
for both CDs.

Will Migration Assistant application transfer my applications' settings and all my games' save file such as Spore and even ported games?

Hello:
Will Migration Assistant application transfer my applications' settings and all my games' save file such as Spore and even ported games?
I doubt if anyone can answer your question. With a new Mac, setup assistant opens the first time the system is turned on. One can also use migration assistant.
I have used both for several years and have never "lost" any data.
If you want to move, have a good backup and then do it.

BOOT ROM VERSION ISSUES WITH MINI MAC POWERPC G4 (1.2)

HI,
I AM HAVING SOME BOOT PROBLEMS ON REBUILDING MY MAC MINI. WHENEVER I PUT IN A BRAND NEW COPY OF EITHER PANTHER OR TIGER THE BOOT SCREEN WITH THE APPLE LOGO CRASHES AND FUNNY GRAPHICS APPEARS, RESULTING IN A FORCED REBOOT AND USING F12 TO EJECT THE CD. THE MAC MINI IS FINE BOOTING OFF OF ITS OWN MANUFACTURE CD, WHICH IS A COPY OF PANTHER, BUT WON'T UPGRADE WITH ANY TIGER DISKS. I HAVE EVEN MANAGED TO CHANGE THE DISKS WITH SOMEBODY ELSE WHO WAS SUCCESSFUL IN UPGRADING TO TIGER.
I HAVE LOOKED ON THE INTERNET AND OTHER PEOPLE HAVE EXPERIENCED THE SAME PROBLEM. THEY MENTIONED THAT I SHOULD CHANGE/UPDATE MY BOOT ROM VERSION FROM 4.8.9F1 TO 4.9.8F4.
DOES ANYBODY KNOW WHERE I CAN GET THIS BOOT ROM UPDATE? I HAVE LOOKED ON APPLE DOWNLOADS, BUT NOTHING APPEARS TO HELP. ANY OTHER SUGGESTIONS APPREACIATED.
MANY THANKS
SUPERHEROTIMO

Welcome to the Apple Discussions!
First, a word of etiquette, writing your post in ALL CAPS is considered the same thing as yelling. Please don't use ALL CAPS when writing your messages.
Exactly which Mac mini do you have? Is it a G4 Mac mini running at 1.2, 1.3, 1.4 or 1.5GHz? (If it came with Panther install disks, it couldn't be an Intel Mac mini.) Which version of Mac OS X came with your Mac mini? Some of the earlier Mac minis shipped with Mac OS X 10.3.7 and will not startup from any earlier version (most of the retail copies of Panther are 10.3.0 or 10.3.4). If it's a Mac mini that shipped later, it would have come with Mac OS X 10.4.2 and, again, won't startup from any earlier version (most retail copies of Tiger were 10.4.0 but now have 10.4.4). Trying to startup from a disk that's the wrong version will usually cause a "kernel panic" and force you to restart.
So, if your Mac mini shipped with Mac OS X 10.3.7, you should be able to use any retail copy of Mac OS X 10.4 (Tiger) to update your computer. However, you won't be able to update to 10.4 from the install disk that came with another Mac. You will need to buy a retail copy of your own.
There are no firmware updates available to download to upgrade the "Boot ROM" on your G4 Mac mini, so that option is really not available.

can i update to snow leopard?? and how? im having a hard time its my first mac.   I need to to create documents, Im trying to avoid buying a new computer.

You cannot upgrade to snow leopard. Snow leopard was the first of os x to drop support for the motorola ppc processors. The latest you could possibly run would be leopard.
Hope it helps,

Will migration assistant migrate a boot camp partition?

I am considering replacing my wife's IMac core2duo with a new IMac. Will the current Migration Assistant transfer the full operable boot camp partition to the hard drive of the new computer? If not, what is the easiest way to do this? I do use Carbon Copy Cloner as a back up, in addition to Time Machine. Thank you.

No it don't migrate the BootCamp partition! You can save the partition with WinClone to save and restore the windows partition.

HT4889 Will migration assistant restore previous settings to a new mac?

I had a hard drive crash which required replacement. The tech shop reinstalled OS 10.6.8 for me and I want to use my Time Machine backup to restore all of my files, settings, bookmarks, etc. I have used Migration Assistant and done a restore but nothing has changed, although I know files were transerred from the backup. What am I doing wrong?

Migration Assistant will restore the user accounts that existed previously. Did it create a new account for the one on the old drive?
Are you trying to restore it back to 10.8?

Will Migration Assistant replace my apps?

This is what I mean:
For example, I had Facetime on my current Macbook, and I used Migration Assistant to get all my apps from my Time Machine backup.
In the Time Machine backup, the Facetime app is in it.
Will the Migration Assistant replace the new Facetime in the Macbook with the old Facetime in the Time Macine Backup??
When I upgrade to Mac OS X Lion, I am planning to use Migration Assistant to get my old apps and files into Mac OS X Lion.
Thanks.

No, neither Setup Assistant nor Migration Assistant will replace an app. See How do I set up a new Mac from my old Mac or its backups?
But there's no indication you need either to upgrade to Lion. That has not been required in any previous version of OSX; it just installs the new version, without disturbing anything else.

Will migration assistant overwrite updates already made

I just switched drives from one using 10.4.11 to a newer one using 10.5.8 (I know that makes me a dinosaur, but it's a G5).
I forgot about migration assistant since I have been using carbon copy cloner to handle copying to new drives with the same OS.
I already imported iCal and Address Book files and Safari bookmarks successfully (using Export from the iCal menu and Safari menu and copying the cards to a separate file) . The problem occurred when I exported (according to instructions in Help) the iTunes 8.0.2 library and imported it into iTumes 10. Disaster! Half the music is missing, none of the playlists made it.
My question: Can I uses migration assistant at the juncture? Will it overwrite alrady imported files and information or make a huge duplicated mess?
Thanks.

Migration assistant will create a new user account, and transfer the files to it. You can omit some broad categories, but you can't "pick and choose" within those categories.
See the pink Migrating User Accounts box in Using Migration Assistant on Snow Leopard or Leopard for details.
That might be the way to go; if you exclude apps, settings, and most everything from that account except your Music folder (assuming that's where iTunes is), then delete (or rename) the damaged one, and copy the transferred version from that user account to where you want it.

Will migration assistant change the default display settings on my new Mac?

I just set up a new iMac and used Migration Assistant to load from my Time Machine. But now the display looks muted and not as bright. Would Migration Assistant change the default display settings on my new Mac?

Migration Assistant may not be the cause. But you should reset the NVRAM and see it that fixes the issue.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the third time.
Release the keys.

HT4889 Will migration assistant/setup assistant transfer applications like Photoshop, MS Office, etc.?

I'm going to be moving from one MacBook Pro to a newer one. My current MBP has the MS Office suite installed, plus Photoshop and Lightroom. Will setup assistant/migration assistant transfer those applications, or do I need to install them on the new machine myself?

It should, if there is nothing the matter with the hardware of the machine. Backup your data as a clone just in case. It is always helpful to have more hard disk space in the destination than the origin.

Will Migration Assistant work with an external drive?

I'm upgrading the hd in my Powerbook and for various reasons have the new drive in an external enclosure. It's got a fresh OS installed and all I need to do now is copy all the data from my old drive that's still in the Powerbook to the new drive in the external enclosure. What's the best way to do this? I know I shouldn't just copy everything over and I got error messages using Disk Images. A friend suggested Migration Assistant but that only seems to want to work with complete computers, not external drives. I've got a G5 in the office too that I can employ if needed.
I want to keep all my settings and prefs intact as I'm told Migration Assistant will do.

As long as the Firewire hard drive is a bootable drive for Mac OS X it should work with the Migration Assistant. These two companies offer that kind of drive:
http://www.macsales.com/
http://www.cooldrives.com/
While it doesn't matter for the machines you quoted, if you choose to migrate to a newer Intel Mac, it won't work. This article explains what to do in that case:
http://discussions.apple.com/thread.jspa?threadID=435350&tstart=10
Also, there is no such thing as a "Fresh install". This tip discussions what installation options exist:

Will Migration Assistant Continue Where It Left Off?

I'm transferring applications from my MacBook to my new MacBook Air via Migration Assistant over my wireless network. It's been transferring for over 24 hours, and says it will finish in 19 hours. I was wondering if aborting it prematurely (using Command-Q) would damage the applications or hardware, and if I continue the migration later, will it pick up where it left off or start again?

It's a really bad idea to use MA over wi-fi, depending on the amount of data you have it could take up to a week to complete! It's much wiser (and faster) to connect using FW or FW800 if both machines have it. Aborting mid migration will only result in an incomplete migration, in that case it's wise to reinstall OS X onto the new machine and start over this time connecting via FW.

Will migration assistant import my previous boot ROM version?
