Netbooting Rev A iMacs Possible?

Got some old iMac Rev A's lying around and some RAM so I thought I'd have a go at updgrading them and getting them to boot from a network 10.3.9 image disklessly. They don't seem to want to do it, just get a grey screen. Checked their fimware Apple's latest 3.0 as far as I know. Built the image from a drive that comes from a Rev A iMac.
Have managed to disklessly boot slot loading iMac's no problem, am I just wasting my time or is there some trick to this. Not desperately urgent but would like to know one way or the other.
Thanks in advance

I thought the tray loads were based on an older version of NetBoot (Version 1?) anyways I know they can be netbooted because I used to have to do that in the past. I was using OS X Server v 10.2.8 on a firewire drive connected to a slot load imac with a small switch between the two. Maybe find a copy of 10.2 Server and install it on a spare machine (G4 Tower or better would be cool) and use that just for imaging. The tray load will be able to find the correct NetBoot server. Also note that I was using NetRestore version 1.2.2. Hope that helps.

Firmware for Rev B. iMac

I have a Rev B iMac, running System 9.1, 512 MB RAM, HARMONi 500MHz upgrade. The Boot ROM is 3.0.f2 which I THINK was installed by Firmware Update 1.1. I've read that I would need version 1.2 of the firmware if I want to install OS X.
However, on reading the description, it looks like the 1.2 update is only for machines that are used in a NetBoot configuration which mine is not. So my questions are:
1. Is the 1.2 update really required for OS X or is the 1.1 version good enough?
2. Would Mac OS 10.3.9 work on a Rev B or should I drop back to 10.2.x?
3. Will I even be able to update either the firmware, Mac OS X, or both since I have the HARMONi card upgrade?

This Apple article
http://support.apple.com/kb/HT1395
clearly states that firmware update 1.2 needs to be installed before updating to Mac OS X 10.2 or later. Despite the description of the update itself, it is the correct update to install. Doing so will NOT prevent future use of Mac OS 9; you can switch back and forth between X and 9 (or even Mac OS 8.x).
Mac OS X 10.3.9 works fine on stock tray-loaders. I think it runs faster than 10.2 on the same hardware because of the optimization effort by Apple for 10.3. Since you have the max 512mb RAM, it should work quite well for you.
You'll have to check your documentation or the Sonnet web site for question 3. If the upgrade was produced before Mac OS X (or a specific release of Mac OS X such as Jaguar or Panther), it probably was never tested to see if it was compatible. Someone with a Sonnet upgrade installed may pop by here, hopefully, with hands-on experience.

Rev C iMac and dust accumulation

Hi Folks,
This is my first post and hope I'm doing this right.
My wife has 20" Rev B iMac and she loves it. But being a material girl, she really really wants a Rev C iMac. The kids will get her old one. The only thing I'm worrying about is dust accumulation, since it seems that you can't open a Rev C case. I open up her Rev B (and my PC desktop) about every 3 months and vacume and blow them out. I'm amazed at the amount of buildup we get so quickly. We live in a very dusty place and our cheap carpet sheds like a collie.
Any thoughts? Can you easily open a Rev C?

No, actually its all been flipped around. You will lay it down screen side up, and undo the screws and pop the front off, instead of the back. The screen is first, then there is a brown piece of heavy plastic between the back of the screen and the back of the internals.
But the thing is if youre looking for the fans to be like they were in Rev A and B, they are different now. The fans arent open like they were. Youll only see the very center of the fans now as shown here-->

But i guess you can still blow it out. Another idea for y ou if you live in a dusty place is adding a piece of very thin cheese cloth or something to the vents under the screen. Cheese cloth is extremely small pored and will filter out even the smallest duct particals. Just cut urself a thiin, long piece and fasten it to the bottom using maybe a light glue on the edges. Just an idea. Could work for you tho.

Wireless keyboard & mouth on Rev A iMac G5.

Hi folks,
As you know, I have a Rev A iMac, which did not come with the Bluetooth module installed.
How do I go about getting the iMac set up for the wireless keyboard and mouse? Is it an internal part I need to buy or will it be an external receiver for the Rev A's?
Cheers.

Optimus...I use Logitech's MX 700 wireless keyboard and the MX 1000 Laser mouse. It is 'RF' technology instead of Bluetooth...both have worked flawlessly for over a year now.
I also believe that you can install an Airport module in your iMac yourself.For Bluetooth connection on your iMac I pretty sure you have to purchase a Bluetooth Dongle that pluggs into one of your iMac's USB ports.I did not use either of those options.

I have a GREAT Rev.B iMAC... I'll tell you why I do preffer it over Rev.C..

I have an iMac G5, 17", 2GHz - rev.B - 2GB RAM. wireless Mouse and KB and I do love it... silent... no dead pixels... no problem. But I'll tell you my concerns about the new models:
1. Now if you wanna go 17" you have to go back to 1.9GHz.
2. And also, you can't have paired RAM that would bring it to 128bits any more... (I have two 1GB RAM)
3.The 2GB RAM itself is SOOOO expensive... you can almost buy another computer...
4.The new iSight doesn't give you a chance of pointint it to another place in your room... I'd have to move the whole iMac if I wanted to show my mum (who lives in another country) my kids playing in the living room.
As I said I don't have any of the problems related to Rev A or B... I believe there might be many users just like me... with a quiet iMAC... and I use Photoshop, Flash, Dreamweaver, iPhoto, iMovie... Internet... all at the same time... It just works!!!
I have no need for Front Row... I am happy with my iMac being 2GHz and having 2GB RAM...
Give your oppinions...
Cheers!

Well I got my daughter a 17-inch ALS Rev B iMac in June, 2 GHz processor, and it is a spectacular computer. However, I read in Macworld that the new 1.9 GHz iMacs are actually a bit faster than the Rev. B 2 GHz iMacs due to other improvements. So going "back" to 1.9 GHz here would actually be an improvement. Given what I have read about these newest iMacs, of course I would prefer one over the "older" one we got in June. But that's how it always is with computers, cars, etc. The newer ones are almost always nicer.
I agree that the older iMacs are more user servicable and the memory set up is more flexible (and maybe cheaper). But the matched pair RAM chips has turned out to be an almost invisible advantage, perhaps measurable in special tests, but not visible in real world situations, from what I have researched on this topic (I looked into this before we purchased our computer without a matched pair). And my daughter's Rev. B iMac came with 512 Meg, we simply added 1 Gig for a total of 1.5 Gig RAM. We will probably never open the computer and will probably use it like this for its entire life. I would bet it would be the same if we had bought a newest iMac, and I'm guessing that most iMac users are like us. Tinkerers and customizers almost always get a PowerMac which have true expansion capabilities. But for the majority of home users who do stuff like email, web browsing, games, MS Office, graphics, iPhoto, iTunes, Adobe Photoshop and the like, the imac is great and the newest ones probably are a shade faster and nicer (and I would guess a bit more reliable since Apple has probably learned some lessons in that area as well).

24" iMac possible water spots/circle pattern?

I've had this issue come up in the last few days with no real explanation. I know the end result is going to be taking it to the Apple store, but I wanted to see if anyone else had a similar experience first.
I cleaned my iMac the other day with iKlear using the instructions (so no one assumes I dumped a gallon of cleaner on the display). This involved spraying a very very small amount of solution on one corner of the cloths so it is damp-not wet.
The display was turned off and allowed to cool then cleaned. When I restarted the iMac, I noticed small, brownish circles in varying sizes in the top left corner of the display. They are very noticeable on white backgrounds, and disappear in darker colors. I removed the "glass" front and the spots appeared to be on the display itself, but nothing worked in removing them...it seems like they are behind the surface of the LCD.
There is no possible way is came from the cleaning as it was barely wet enough to even feel damp. The only thing I can think of is somehow something entered through the back of the display via the fan vent/line?
It's livable I guess, but highly annoying. Not sure if it's worth paying to have fixed, but if anyone else has seen something like this, please chime in!
Cheers.

As a matter of fact, I came to the support forum looking for anyone else with this issue. A few months ago I had my iMac's screen replaced due to serious issues with the inverter. The new screen looked better and I happily forgot about it.
Until a few weeks ago - I noticed what looked like half of a clover burned into my display in the top third towards the middle. Thinking it was dirt, I cleaned the glass panel. No results. I removed the glass panel and cleaned the inside and LCD screen. No results. I tried resetting the SMC and PRAM and that didn't help.
I was dismayed about this defect but just ignored it and after a while I hardly noticed it, unless I looked right at it. Last week I noticed another blotch on the screen, to the lower left of the first, that is IDENTICAL in design. I have no idea what could be causing this but it is clear to me that this is not a burn in issue, as I've tried the fix for burn in to no avail.
Good luck with this. I'll be taking mine to a service center at some point as well.

Connect PS3 to latest 27": 3,2 GHz iMac - possible?

Hi guys,
Just moved to Zurich and left my FullHD screen back home - now looking for a new iMac 3.2GHz, 27" and using it as external monitor for my PS3.
Did some reserach but didnt get an ultimate answer if this is possible or not, seems like there are solutions out there that solve this problem but not entirley sure which one is the best/ if it works with the iMacs 27" that Apple is currently stocking.
Can anyone help? Not sure if that is of interest but i live in Europe so this might effect the adapters I require?
Thanks in advance,
Tom

Hi Tom,
As far as I know, you need Thunderbolt to use the mid 2011 & up iMacs as a monitor...

Netboot Issue - White Imac to 2007 AL Imac

Hi
We have just purchased 20 Mid 2007 Aluminium iMac's to add to our existing network. - The one i have taken out of the box was pre-installed with 10.4.11 with a Leopard Upgrade Disk inside (said that Leopard is not installed on the machine but can be upgraded by use of this disc).
We have a 10.4.10 Netboot image (built on a 17" 2006 White Intel iMac) on our XServe that I have tried to restore onto one of the new Aluminium Imac's.
The actual netboot operation worked fine and the operating system booted up on the new Aluminium Imac - but then i have found;
a) the onboard LAN port is greyed out and cant be configured
b) the isight camera does not work
c) the sound does not work
I downloaded the 10.4.11 combo updater and ran that on the machine hoping that it would replace drivers, etc - no chance.
Is there a way i can get the specific drivers for this hardware, as I dont want to have to install all of the programs and settings that we have for our network. then have to clone it 20 times.
Or is there a way i can remove the settings for the missing items (network, isight, sound) from the computer prefs and get them rebuilt on system startup?
Frustrated that Apple support has been less than forthcomming, with the reply of
"upgrade to Leopard" - Upgrading to Leopard is not an option.
Not understanding the problem which i was facing.
I might have to return the 20 and just get hold of 20 of the White Imac's - which are on sale from our reseller.

Thank you so much for your information. I have been using a Seagate GoFlex portable drive as my back up disc with TimeMachine on my iMac. The AirPort Time Capsule is arriving tomorrow with my new iMac. My question to you is this: Will it be easier to wait till tomorrow, set up my AirPort Time Capsule and back up my old iMac to it and then use it with the Startup Assistant to transfer my stuff or will it be easier just to use my GoFlex back up disc? I have had some issues in the last year where Time Machine send me a message that the (daily) back up failed because the file got corrupted and I have been unable to fix it so that I have to reformat the disc and back up everything I have. Just an FYI, I don't have a huge amount of stuff on my iMac even if is almost 7 years old....I have 900 GB out of 1TB available. This is one of the reasons I felt it's time to replace my iMac.
Right now I have a clean encrypted back up on the GoFlex but I don't want to transfer anything I shouldn't to my new iMac. Please advice and thank you.

22 inch LaCie Blue II to new iMac - possible?

I have a new 21" iMac and an old 22 inch LaCie Blue II computer Monitor that I'd like to add as a second monitor because I like the tonal quality for print - is it possible? Will I be able to span or is the old LaCie to slow? Thanks

Could my iMac possibly just have a temporary case of heat stroke?

After working on my iMac off and on all day, I left it up and running when I stepped out of the room briefly and returned to find it had shut down. This particular Mac is networked to a PowerMac G4 and dual core iMac, both of which seem to be working fine .. . (as was this one, until this problem started).
Hitting the power button did not get it up and running, although the chime seemed to work; however the screen remained black. It was hard to tell, but I also think the power switch was working a little erratically, because at various times it seemed like it required eiher a "forced quit" and restart, restart with the shift key on — or sometimes just a restart alone to ring the chimes. Bottom line though, was that while the on button sometimes lights up, the screen remains black.
Unfortunately, my optical slot drive died about six months ago which is how I ended up with the dual core iMac — but so far have not used it much, since most of the software I normally rely on is not yet available for the new model. So instead, I have been switching back and forth from one computer to the next, as needed. However, because of the drive problem, I have been unable to boot from either the hardware diagnostic or system CDs to look for or repair possible errors.
Although the two iMacs currently are connected via Firewire, I have not yet taken time to see if I can transfer and save the most important data — hoping to get all systems up and working properly first.
More importantly, I'm also hoping one of you Mac wizards will tell me the problem is just weather-related, since the temp outdoor has been in the low to mid-90s all week and probably even hotter indoors. Is there any point in just letting things cool down overnight instead of repeatedly hitting the "on button" . . . or does it sound like my goose is really cooked?
Anyone have another idea of how I can rescusitate this machine?

Update:
Sorry to report that while I waited in frustration for some sort of response, my iMac gave up and died.
Since initially it looked like it might "only" be a power problem (not worth repairing, as the CD drive also pooped out about 6 months ago), I was arranging to have the drive reincarnated as an external drive, only to learn that the drive, too, was on its last legs. I have no way of knowing what's on the drive, so am still trying to decide if it's worth paying for data recovery. Luckily I think have backups of the most important doocs.

Rev B iMac Quieter with 10.4.3?

Does anyone else think the fans sound different after applying the update? My Rev. B sounds about the same as my Rev. C. Let's compare the before and after.

For what it is worth, I agree with Peter. My iMac rev. B is running quieter after the update to 4.3. It will be interesting when I erase and re-install everything in about two weeks if I notice a change stepping up again through the update.

Migrating from 10.6.4 MacBook to a 10.4.11 iMac, possible over network?

I've had an iMac for a few years but after getting a macbook this past xmas I rarely use it. I decided to get my iMac up to speed with my macbook using migration assistant. I used it to setup my macbook when i got it with no issues. So after running migration assistant to transfer back to my iMac it duplicated users. So I had 2 users with my name, 2 with my wife's etc. So I thought I'd be smart and I booted from the disc that came with my iMac (osx 10.4), deleted everything, ran all the software updates and tried using migration assistant again. My issue is this, Migration assistant on the iMac, under the from another mac option will only recognize a firewire cable. My macbook (came with osx 10.6) doesn't have a firewire port. Am I missing something? Is there a way for me to do this with a cat5/6 cable? I've tried having them on the same network and using file sharing uploaded the entire macbook HDD onto the iMac, but it wont let me boot from it. I also am unable to copy the macbooks HDD onto the macbook itself. What do I ned to do to get htis going, i've scoured all the forums I can find and have found no answers that work for me. I'm not a computer whiz and I've tried everything I know how to do.

Though I'm a little confused too, Migration Assistant is probably designed to use Firewire for a good reason, though creative network solutions might be possible. (I stopped using simple ethernet cable when Apple Talk stopped being supported.)
People are know by your computers as simple integers. They used to start with 501. So 501 on machine 1 could be 'Fred', 501 on machine 2 could be 'Jim'. I'm guessing it just converted, say, the incoming 501 account to 502. Don't know if that helps.
Firewire isn't needed for DVD transfers, is it? I've never tried this, but I should anticipate that it would stop and ask you to insert a new disc.

Copies MacBook.dmg to DVDs just by creating the image & dropping it on the 'copy' window. I take it you've tried rebuilding the iMac with 10.4.11, copying MacBook.dmg to the iMac's hard drive, and telling MigrationAssistant that that folder is a DVD folder? (Devices are all just folders to Unix.)
I've used this application only once, to move Applications from 10.4 to 10.3, and it worked perfectly. I archive or backup all other data, so I just copied it or restored it to the older machine.

Jedi Academy 1.01e Multiplayer Freezes iMac - Possible issue with Leopard?

Just migrated everything over from my old iMac G4 17" to the new Intel iMac, Jedi Academy single and multiplayers seem to be freezing my iMac hard. I have downloaded the UB patch (1.01e) from Aspyr, made sure all Apple software was up to date, done a clean install after clearing out all the prefs/.plists for it and it will still lock up.
This occours trying to run Multiplayer, it gets to either 'Awaiting Snapshot' or just joins the server and the system freezes.
I've been working with Aspyr's technical support, initially they could not get the problem to happen in single player but when they tried multiplayer they experienced the same problem of it freezing the computer. They have passed it on to their Dev team as a possible Leopard problem but figured I'd mention this here as well in case other users have this issue.

Cannot say, can you use Real Player until it is solved, or flip for mac?

Installing Internal Hard Drive in iMac possible or reliable?

Is it possible to install internal 2TB hard drive in iMac? I have my complete internal Hard Drive full in the iMac. And I work heavily on Final Cut Pro and always have heavy work data, so should I get external 2TB for editing and working in FCP or is Internal more reliable?
Thanks in Advance!

Apple doesn’t ship an iMac with anything larger than 1TB and opening up the current iMac voids your warranty and isn’t easy. I’ve cracked open every computer I’ve ever owned and have a large amount of experience with modding. This iMac will be the first computer I won’t be opening. So if you want a larger drive, external will be the way to go. Look at the LaCie Thunderbolt drives. I’ve not pulled the trigger yet but when I do get a TB drive, that’s probably where I’ll go.

Bad noise/ fan speed problem with Rev B iMac

Like a lot of other people, I'm having problems with ridiculous fan noise. I've read through the forum and tried the following (with no success):
1) Reset SMU (x2)
2) Ran Maintenance Scripts. (x2)
3) Removed the back and blew dust from fans, ports, etc.
The processor is set to automatic. The problem occurs whether or not I have any peripherals plugged in. I get the noise/rpms when all I have running is Safari and XRG.
On certain websites, the CPU fan will climb to 5600, CPU temp to 79C, with CPU usage at 80-90%.
Does this sound like a logic board problem? Something else, possibly?
Basically, I'm trying to cover all of my bases before I get on the phone with AppleCare. I'd like to try to keep that as short as possible. Thanks in advance for any help/comments.

iMac G5 (ALS) 17" 2.0GHz 512MB RAM Superdrive Mac OS X (10.4.8)

Just an FYI. During my iMacs motherboard replacements (3) I was never asked for a case number once. I spent hours on the phone with Applecare when in reality I already new I had a hardware problem and if I would have just taken it in it would have been fixed quicker. The third time I took my iMac G5 in for service the local tech told me to call up Applecare (3rd time then call) and ask for a replacement stating that if they need to call me he would explain that I had a lemon. In everyone of the three bad motherboards the fans spun out of control so I have more experience than I would prefer on this subject. They did step up and as you can see in my profile I have a new Intel iMac courtesy of Apple.
