MDD Dual 1.0GHz Power-up chime, NO BOOT or video after Kernel Panic

My MDD DP 1.0 (FW400) suffered a recent kernel panic on startup, and since then it has failed to boot...
It chimes and the power light stays on, fans run, but seems not to access the hard drive, and or power the DVD drives, USB/keyboard, or Video.
I Can't reach her via ARD either.
I have tried:
Reset PMU Power cord in.
Reset PMU Power cord out
Replaced the Battery,
Left battery out for 48hrs
Started up holding X key
Started up holding Space bar
etc. etc.
Any ideas? I really don't to loose this trusty old server.
Other details.
Hard Drives Are 2 month old Hitachi 7k250 have been tested as working in a D2 enclosure
Video Stock Radeon 9000 as new
PSU was replaced as part of the PSU replacement programme
Extra 1GB (2x512) Crucial installed when new.
Thanks In advance

With care, you can manually open the optical drive tray. Pull open the outer door and use a good light to look at the front face of the drive beneath the hinged door. Somewhere there is a small hole, often under the tray, just slightly larger than a large paper clip's wire diameter.
Partially straighten a large paper clip and GENTLY insert the wire STRAIGHT into the hole. You should feel resistance after about 1/4 inch. Apply a little more pressure and the tray will start to move out. Grab it with your fingers and gently extend it all the way. I had to do this when I had the boot problems I mentioned.
Once you insert the System CD/DVD, push the tray closed and try to start, this time holding down the "C" key on your keyboard to force the computer to start from the optical drive.
BTW, be sure to check all internal cables for secure connections. As you're not even getting a gray screen, I'm getting a little concerned that your power supply has taken the long trail. When my MDD did the boot craziness, I at least got a gray screen.

G4 MDD Dual 1.25 - Aperture 2 - Do I need newer Video Card to run the app?

I am hoping someone can help steer me in the right direction. I spent all morning reading about Aperture 2, decided I must have it, downloaded the trial version and THEN found out my computer will not run it. When I try to install it, it says that I don't meet the minimum requirements but doesn't specify exactly what the problem is. The Aperture minimum requirements are confusing to me in that it says Power Mac G5 with Intel processor, BUT it says you can have a G4 Powerbook with a 1.25 GHz processor. My Powermac G4 has a 1.25 processor. Not sure if that is the problem or if it's my video card which is the standard ATI Radeon 9000 Pro. If I replace my video card will I be able to run Aperture 2? If so, which ones would be compatible with my older Mac? — Thanks, mark

Sick dual 1.0Ghz MDD

I inherited a snazzy dual 1.0ghz G4 MDD and am having trouble diagnosing it's ailment. It chimes when powered on, I can hear the HD spin up, but after about 8-10 seconds the fans spin up to full speed, nothing comes on the screen at all and the fans just continue to spin at full RPM.
One of the processors has a small amount of brown goo caked on near the die (not on the surface, just next to it - similar to the goo that oozes from a capacitor that's blown) and I was able to remove all of the crusty thermal paste and reapply new paste but the same thing happens when I try to start it up. I know little of the machine's history except that the person who owned it was attempting to install the OS at the time it crapped out.
If anyone has had a similar experience or knows what might be wrong please lend a hand. I'd like to be sure of the problem before I rush out and but a replacement MB or CPU.
Thanks!

Ewww...sounds bad. I've had that happen once. You see, the fans are controlled by the CPU's temperature, and the faster they move, that means the hotter the chip is. Also, that dried out thermal paste was either caused by, or the cause of your problem, as it is either a sign of excessive heat or non adequate heat protection. Sorry to say this, but I think the CPU is fried. That explains the rapid acceleration of the fans. I COULD be wrong, but that is normally what the syptoms describe. I'd have it checked out by a mac genius, as he can give you a more definate answer. If that's the case, you're gonna need a new CPU, or maybe a new logic board.

1.8Ghz & Dual 2.0Ghz Logic Boards/Power Supply

I have a perfectly fine working 1.8ghz G5. I also have a dual 2.0Ghz G5. However, the dual doesn't power up. I'm pretty sure it's the power supply. But, I'm not positive.
My question is. Is it possible to put the dual 2.0 logic board into my 1.8ghz machine? The inside of the cases look very similar. Or is there a way to test the logic board of the 2.0 before I take everything apart?
Thanks..

The CPU speed of a PowerMac G5 is always 2x the bus speed or less. Thus, with the 900 MHz bus speed of the 1.8 GHz motherboard, your 2.0 GHz CPUs would clock down to 1.8 GHz at best.

Dual 1.8Gb power mac G5 won't start up. No chime or video.

I have a dual 1.8Gb power mac G5 that won't start up after the weekend. The computer was being run as a server using OSX 10.3. When my employee came in on Monday she said the fan was running full blast, but there was no video and the computer was totally unresponsive. The computer has been restarted with and without periferials plugged in, reset the PRAM and SMU/PMU/Cuda switch. Tried different monitor. I've put the hard drive in another G5 and it worked fine. I've also noticed that this computer does not click (sounds like a relay) when plugging/unplugging the power cord. I've always noticed my other G5 does this. Any ideas? I'd like to try and fix it myself and save the "Apple Authorized Service Provider" costs. Thanks!
Eric

It doesn't seem to matter if anything is hooked up or not ... mine nor his. I've tried three different power cords in two different locations. I wouldn't know what to "tighten" inside.
Most recently at home I've tried using just the mac keyboard an mouse connected to there own USB ports off the back of the CPU and then the Apple 17" studio display from the ADC output. Still nothing. I then tried the same setup, but with a 17" CRT monitor using the DVI output and the adaptor (finally found the adaptor). It booted up fully once, but then died (I wasn't there when it happened, but when I came back no video, fans on full, and unresponsive). I hadn't had any more success until this morning when I tried to fire it up again, and it came on, but with distorted video (the one that says you need to restart your computer). I'm beginning to think this is a bad power supply problem due to the specific component failure (same bad capacitors as the iMacs), but mine doesn't quite fall within the serial number range (just before).
Thanks for the help!

G5 dual 2.0Ghz bought in 2003+ 30" cinema display?

Hi all.
I bought the first generation G5 dual 2.0Ghz in 2003 and am sure that I have Radeon 9600 pro video card installed in the computer. Currently, I am thinking of buying 30" cinema display and did some research on it's specification.
I found that Radeon 9600 pro: pc/mac edition is compatible with the monitor, but I am wondering if the 9600 pro version can support the monitor.
If it can't, would anyone like to recommend a good graphic card except 9600 pro:pc/mac edition? Ugrading from original 9600 to 9600-pc/mac edition just sounds like a waste of money because of their similarity of specifications.
Any responce would be greatly appreciated,
Thanks..
KYE

To find out if your Mac already supports a 30" 2560x1600 resolution, go to the monitor resolution icon at the top of your Finder/menu bar on your desktop. Click on the icon and explore the various resolution possibilities. If they go all the way to 2560x1600 your good to go. No need to buy another card.
Unfortunately, I purchased a similar model in '04 and it does NOT include a sufficiently good enough graphics card to power the 30" [I was told by the apple dealer in '04 that it did. It doesn't.]
My research in to graphics card options for 'our' situation is as follows:
Low End: Radeon 9600 Pro Mac & PC Edition [$199]
Mid Range: Radeon 9800 Pro Mac Edition* [$250]
High End: Redeon x800 [$399]
I don't think the Rad9800 can drive more than 2048x1536. This might be satisfactory for you, it's not quite the maximum of 2560x1600, but your menus will be a little bigger at 2048x1536
Good luck.
My question to no one in particular is: did all early PowerMac G5 towers ship with AGP 8x slots? or 4x slots? or what?

ATI X800 XT 512MB on MDD dual boot dual 1.25Ghz.... possible?

Hi,
Just looking to see if I can install a Mac version of the ATI X800 XT 512MB on G4 MDD dual boot dual 1.25Ghz machine?
If so... great... I'll go pick it up straight away.
thanks
PS. I know it won't accelerate 9.2.2, but I already have the 9200 PCI card to accomodate that.

Just following up on japamac's excellent response.
ADC presents a seriously limitation on cards since the only two retail cards (no flashing, no fuss) on the market are the ATI 9600 and 9800, both without ADC.
I use a modified 9600 Pro from a G5, which has an unpowered ADC. Unpowered because the the ADC tab doesn't align, although some people have modified the card further to get power to the ADC port. For info on both of those mods, see:
http://www.pistolerapost2.com/viewing/96002g4.html
There is one last card -- extremely -- I can think of with ADC and more oomph than the retail 9600: the Apple OEM 9700. That was a BTO option for the MDD. Here's some info on that card:
http://www.xlr8yourmac.com/Graphics/Radeon9700PROOEM/index.html
Again it's really rare because it wasn't available even as a BTO option for very long. They fetch a premium on the used market when you find them.
What ADC monitor do you have? I hope an LCD. In which case, something to consider is the Apple ADC-DVI adapter which will set you back $100. It's basically a kind of splitter, with a brink supplying power to ADC monitor while passing the signal from the DVI port. Yeah this adds to your costs, but gives you more options in terms of cards.
Oh more thing about 9.x acceleration which you mentioned. With ATI cards, you might need to pull an extension or library from the Extensions folder to keep 9.x from stalling at boot. I had to do that with my 9600. Sorry, I'm on my MBP now, so I can't tell you which ones. Let me know if you need/want to know which ones I pulled.

Jumper Settings for Second SATA-II drive Installed Into Dual 2.0Ghz G5

I have installed a second SATA-II 500GB Maxtor drive into a brand new (purchased as re-furbished computer from Apple) dual 2.0Ghz PowerMac G5. The drive has four connector pins with a jumper slide over the last pin on the right. Before I power up the computer I want to verify the correct jumper settings. According to the Maxtor website, no jumpers are required since the "serial ATA host automatically determines the master and slave hard drive." And according to a MacSales tech (this is the vendor where I purchased the Maxtor drive) I should pull off the existing jumper. Can anyone verify if this is, in fact, the correct jumper setting (no jumpers on the connector pins) for this drive on this system?
G5 dual 2.0 Ghz Mac OS X (10.4.8)

Hello! From the Maxtor web site.
"PLEASE NOTE: Unlike standard ATA drives, Serial ATA drives DO NOT require the use of jumpers to configure the drive. Please disregard any references to jumper settings and Master, Slave and Cable Select configurations in the Maxtor Installation Guide."
I'd leave the jumper as is came when you got it. tom

PowerMac G4 MDD Dual 1.42 not recognizing hard drives

I have a PowerMac G4 MDD Dual 1.42 GHz, and I just moved across country, and it was working before the move, now it won't start up. It goes right to a grey screen with a blinking question mark and finder icon. I have 2 hard drives in it. One with Leopard, and the other with Tiger, and it won't recognize either. I reset the PRAM, I checked all the connections inside, started it up holding the option key and it doesn't show either hard drive. I also started it up with the Leopard install disc and using Disk Utility it still couldn't find the drives! Next thing I am going to try is resetting the PMU and see if that works...otherwise both hard drives went bad or possibly the cable for both of them went bad??

... I checked all the connections inside...
When you checked the cable connections, did you check both ends of all cables? For example, if the moving loosened the ATA cable at the logicboard/controller end, checking the drives' connectors won't reveal much.
Do the drives spin up when you power the machine on (you may need to open the side panel and gently touch the drives while booting to test this)? If not, suspect a power cable connection issue. If they do, suspect an ATA cable connection issue.
Best way to confirm a cable connection is sound is to undo it and redo it - they can look okay when they are not okay. Do this with the machine shut down, of course.

Is there much difference btwn dual 1.8ghz and dual 2.0ghz

Hi,
I have seen a dual 1.8ghz (M9454LL/A) second hand with this spec:
Machine Type: Power Mac G5
Machine Model: PowerMac 7,3
CPU Type: PowerPC G5 (2.2)
Number of CPUs: 2
CPU Speed 1.8GHz
L2 cache (per CPU): 512KB
Memory: 1.25 GB
Bus speed: 900MHz
Graphics Card: GeForce FX 5200
ATA Bus (DVD): Pioneer DVD-RW DVR-117D
Serial-ATA (hard-drive): Maxtor 80GB
for a good price around £800 which would leave me with money to buy a monitor.
This model already has airport built in and additional ram added.
I am a music producer (running digidesign protools LE) and need a studio computer to see me through the next couple of years. I have been looking at getting a dual 2.0ghz machine but these are invariably more expensive and I would have to pay to add the features this model already has, as well as purchasing a flatscreen.
Basically I want to know how much of a performance difference i will see between a dual 1.8ghz machine and a dual 2.0ghz machine.
cheers guys

Ok that dual 1.8 is not much difference from a dual 2
Your dual 1.8 has a 900 Mhz front-side bus per processor
The dual 2 has 400 more Mhz total in CPU speed (not much really) and a 1000 Mhz frontside bus per processor.
So the difference is minimal.
You could upgrade that video card to a AGP ATI X800 and 3D game all the latest ones with no problem. (I would before they are all gone)
If you get yourself another internal hard drive, something large like a 250-300GB SATA and keep your user files in there instead of on the 80GB Maxtor, your performance "feel" would be pretty good as well. (no Western Digital, they upgraded their SATA specs)
And you got a Superdrive, so you can burn dvds.
If time doesn't equal money, and your not constantly pushing your CPU's day and night, this machine is a good buy IMO. You should get a good 3-4 years out of it, especially if you know when to stop upgrading the OS/apps.
Yes I say you got yourself a good buy there.

P/N for Install discs, G4 MDD, Dual 867

Does anyone know the Apple part numbers for the original discs that came with a Power Mac G4 MDD, Dual 867Mhz? or where to get them?
After reading through the postings here I gather they are a MUST have to be able to boot OS9.
If anyone knows of another way please let me know.
Thanks,
Jeff

Hi, Don and Jeff. I made a list a while back that was primarily focused on the part numbers for all the retail (universal) installer CDs. I do have some model-specific discs' part numbers, but not the one for the disc you need, Jeff. Calling Apple may be the best idea. If they're out of that disc and have no record of what its number is (very unlikely, I suspect), try reposting in the PowerMac G4 forums and seeing whether someone who has the same model can supply the number for the disc. Good luck!

MDD Dual 1,25 Ghz random shutdown and false time/date

Hey,
A friend of mine has a dual 1,25 Ghz MDD and he really likes it, but for about a month now the mac behaves very strange. The Mac shuts down itself (not the standard shutdown processes, just shuts down) and sometimes there are is a wrong date/time displayed !
I think that might be the batterie, do you agree ? Or can this also be a Board or power supply failure ?

I think it prudent to find out a little more about what your friend calls a"freeze," and to post the version of the Mac OS he's running.
Some freezes are just that--nothing works and you get no notifications of a problem. The other kind is accompanied by a new screen in multiple languages saying you need to restart the computer, or you simply see a lot of code-looking text across the scene. The later is a kernel panic and can be due to either hardware or software. If it's a kernel panic, this article may prove helpful:
http://thexlab.com/faqs/kernelpanics.html
If he's getting real kernel panics, search (command-f) for the word panic and, if the search returns a file called panic.log, double-click it and see if any clues are present.
Your friend should also determine how much free space the boot volume has. Single-click on the boot volume (always the uppermost drive icon shown) and do "Get Info..." from the Finder's "file" menu or simply press command-i. The resulting window will show capacity, amount used and amount free. You want at least 20 percent of the volume to be free space so that the OSX virtual memory process has someplace to write files.

G5 Dual 2.5 CPU Power PC will not boot unless I remove the Plastic Sheild.

G5 Dual 2.5 CPU with 4 gb of memory will boot everytime if I take the plastic sheild out. I bought it from a guy who would turn it on then let it sit until the fans revved up after about 5 to ten minutes. I figured out that it would boot everytime if I removed the plastic sheild. Now I am trying to find a permanent fix for this issue.
Thanks for any assistance anyone can give.

I don't think its just a plastic shield and door - there is a contact switch that signals when these are removed and the fans rev up to a higher speed. My guess is its the higher speed of the fans that's keeping things cool during the power surge of the boot stage thats allowing it to startup.
When the doors are on and the fans are kept low there must be some hardware failure that is occurring during boot up - that seems to be prevented when speeding the fans up. And after the initial boot up power surge, things run cool enough that I can safely put the plastic shield and door back on and the computer keeps running fine (it ran OK all night).
I can think of no other logical explanation at this time.
Any other ideas?
What puzzles me, is I use this computer to do some heavy 3D graphic renders and have run it intensely for days at at time with absolutely no sign of failure during operation once its booted up. I've never had a freeze or anything like that. So when its so reliable during operation, why so fragile during boot up?

It will not run on Mac OSX 10.5.8, on a G% dual 2.0ghz, now my older version of Firefox is gone...

I downloaded Firefox 4.0 and It will not run on Mac OSX 10.5.8, on a Mac G5 dual 2.0ghz. Now my older version of Firefox is gone...Why won't it work, the download page says it is for OSX and does not say it will not work on any particular OSX. Can your clarify. And can I get the old Firefox 3 back or should I continue using Safari....?

Yes I've read every one of them, none of them provide solutions whatsoever, I have spent about ten hours on this site in the past two days to no avail, none of the "resolved" threads provided any sort of solution for me, I have tried everything suggested on this website so far, multiple times, to no avail.

My iBook will not display after Power up Chime

Please I need Help.
My iBook (16VRAM) Does not display after the power up chime. so i have tried to reset the PRAM by holding down CMD, OPTION, P & R after the chime, But Nothing Happens, I dont hear a second chime (I dnt Knw how long am suppose to hold down the keys, But i held it for 2 mins and still nothing)
Please help.
Thanks.

Welcome to Apple Discussions Aaron
Force quit in the middle of an installation spells "trouble". Try starting the computer in Safe Mode. If successful, restart the computer and see if it fully boots. If not, you more than likely have directory damage that needs to be repaired. Disk Utility may be up to the task.
