Should I update my boot rom?

Greetings to all,
I just purchased a power mac g4 1.25 dual processor. I have the boot rom 4.5.7f1. I read somewhere that it cannot be updated unless booted in os 9. I do not have os 9 on this computer. I was trying to find the boot rom download for this computer but was unable to.
Can I update the boot rom, without os9, and where can I find it.
Thank you for any help.
Marco

Is boot ROM the same as firmware so that there is no update at all?
Yes, and if no update is available from Apple, then it can't be updated and/or isn't needed.

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.

Error message when starting Boot Camp: 'You must update your computers Boot Rom'

I installed the latest firmware updated to my late 2011 13 inch MBP. Rom version is MBP81.0047.B24. Now Boot Camp won't start. Says I need to updated my boot rom. But its updated already. Anyone else having this issue? Thanks.

Fire the people that write meaningless message errors. Oh, can't. Get the point though.
you mean you are trying to use Boot Camp Assistant? Boot Camp has become meaningless through over use for too many things.
It doesn't even know bout your EFI frmware, I can say that.
You should though use Lion Boot Camp Assistant and the BC 4.01 drivers for your system.
Zap pram
repair your hard drive with Disk Utility - from DVD
make sure your free space is not fragmented, is contiguous and also large enough, 40 + 20GB for Windows, and still leave 20GB / 20% free for HFS.
And backup(s).

Trying to install boot rom update on 10.7.3 - but will not

I'm trying to install boot camp and I can't install until I update the BOOT ROM. I've downloaded the package macmini2011efiupdate.pkg and this coorsponds with my 5.2 model identifier. I have already updated lion to 10.7.3 and I seem to think that maybe the boot rom update was intended for 10.7.2 and it won't let me install on 10.7.3 because it thinks it isn't compatible?
The message I get when I try to install the Boot ROM update is this software is not supported by your system.
Sincerely, Kevin

Same feeling here... I am not advocate of mac. I bought one only for iPhone development. However the hardware is cool, it is my main home PC with Windows 7. For the OSX I left only 80GB disk space and the rest goes for Windows. Well, things would have been different if the OSX was workable the moment I bought it but it was not the case until this EFI update. Now I do not even think of get rid of the Windows.
Back to your case, what is wrong with your mac so you long for the update so badly? From the link you provided I gathered that your mini 5.2 is the one with ATI Radeon discrete graphic. Are there any problems with those? I thought only the HD3000 were so "crappy" because they were the cheapest version.
Anyway, if you slow down, do not expect too much, you will just gradually get used to the OSX philosophy. It's just different than Windows or Linux (on purpose I think). If you lunch Finder and Navigate to Application->Utilities there are the very useful things for start: "Grab" let you do screen capture and "Console" is like the EventViewer on Windows. You should lunch the Console, select "All Messages" and try the update again - look if there is anything logged from the update package which might help. You can also try to reset the SMC and check if that would help - if I remember correctly, the procedure is to unplug everything from the mini, wait ~5 minutes, plug only the power cord keeping the power button pressed for ~1 minute. The funny thing about that is that you have to follow it literally, I left the mouse and keyboard connected and I got wierd result - the fan was keeping at maximum speed. But try to verify the exact procedure on apple web, sorry I am a bit lazy now to search for it again ( I did it because I was desperate about fixing the sleep-resume problem). Anyway, again I would recommend not touching anything if you do not have any problems with your mac just because it does not want to "get something new". Just a common sense
Well, sory I just have scrolled up, and see your originall post why are you about the EFI update. It's really bad the Boot Camp does such check. It really does not make sense. You can do the install manually if you like, it's not so complicated. First go to disk management app in the Utility folder, and partition your disk formating the new one as FAT32 (the one which would be your windows partition). Next boot your minit keeping left alt pressed - you should see a list of booting devices so if you connected USB DVD (or pen drive with Windows - it's simple to do it yourself, just google for the recipe) you can boot the windows install. During the installation select the FAT32 partition and let Windows format it as NTFS and that's all. You can download from apple web a package for all drivers for Windows 7, and just install it in your windows. To choose which os you would like to boot, you can always do the left-alt select. I opted for installing rEFIt - it's really cool boot menu.

How do I update boot-rom

I have an Macbook from 2006 which I udated 2010 to Snow Leopard now v10.6.8. I have Office for Mac 2004 installed. Something is wrong with the color sync tool and a message said that I have to update the BOOT-ROM version.

I just installed it today (twice actually, after changing my mind about something) so I can tell you how to do it. What I did was completely ignore Boot Camp and used Disk Utility to format the intended Windows drive as FAT32/Master Boot Record. Then I just rebooted with C held down and the Windows 7 CD took care of the rest.
I have a 2009 Mac Pro so all my drivers etc were on my OS disc. If you need to burn the drivers, by all means use Boot Camp just for that part
I got a warning in Windows 7 that Boot Camp had issues with the RC but it has been rock solid so far.

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.
The long story:
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'm posting this in the Time Capsule community as well, since it might be an MA issue. Don't get mad, I'm new. If that's against the rules, I'll take it down.

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.

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.

Welcome to Apple Support Communities
As you can check in this website, you are running the most recent EFI and SMC version available for your computer. In this case, reset the SMC and the PRAM, and finally, try to use Boot Camp Assistant

HT1899 Is Boot Camp Assistant supported in Mac OS X 10.8.1? I am getting an error "Boot Camp Assistant cannot be used. You must update your computer's Boot ROM firmware before using this setup assistant."

Need boot rom update, Don't got MacOS 9!

I got a dual 1.1 G4 for one of those gigabit ethernet beasties. Right now it is a paper weight cauz I don't got MacOS 9. You can't run the updater under MacOSX (panther?). Probably won't run under Linux either. Suggestions anyone? Can you download MacOS 9 yet?
kevin

A friend of a neighbor loaned me a 9.1 install CD. It be flashed now. The upgrade seems fine (he says with fingers and toes crossed).
FYI: The actual "flashing" did not procede as I expected. I have this thing set to stop at OF. When I did the power on while holding the programmer button I expected it to do the flash then. It did not. It came up to the OF startup screen and prompt. The actual flashing happened when I typed boot?
Also, I initially tried to run the updater from a zip disk. It would not work. It did work when I copied it to the startup disk?
Yo Apple dudes, any chance additional boot rom upgrades for this thing will be OSX or Linux or OF boot CDs so I don't have to hunt for MacOS 9?

Boot camp assistant won't run - says must update boot ROM.

Just updated my mid-2010 13" MacBook Pro to ML 10.8.2. When trying to run boot camp assistant, I get the following:
No firmware or Boot ROM update seems to be available, however. EFI update 2.5 is not for my Mac, nor is v.2.6 - others don't install, either.
Anyone have the answer to this problem?

Hey thanks!

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,
