PowerMac G4 (AGP Graphics) not booting after processor upgrade. Help!

Hey,
I just bought a Encore/ST G4 SG4-1600 1.6 Ghz (Duo) and trying to get my PowerMac G4 (AGP Graphics) (originally 500Mhz) to run with it.
I have upgraded the firm ware to 4.2.8f, and restarted the PMU on the Logic Board.
I have also checked that my logic board is two core compatible.
The computer just sits there after it's been turned on, the the motherboard is lit up and the all the fans are running, but it stops there, no screen, tone, or anything. Will just sit there with out ever spinning a hard drive.
If some one could help me get this going, please help!

I downloaded it, (for Mac OS 10.4.x) but getting a continuos error message reading:
Programing Not Successful!
Boot Section 0xF029672E
Recovery Section 0xC381FF3F
Main Section 0x73CCD5A8
This happens everytime I try to run the app. Could it be because it's OS X? I had to intall OS9 to update my firmware.
It says it's made to work on a PMG4 (agp) so I don't understand what's happening.

MacBook not booting after RAM upgrade

I'm sorry if the case has been already posted.
Yesterday I took my MacBook Alu unibody late 2008 to a RAM upgrade (from 2 to 4gigs) to an offical Mac Reseller. They installed it and showed me that the system loads properly and recognized the new RAM.
I took it home, started working on After Effects and Photoshop and when i wanted to check a video on Quicktime, this program refused to boot.
Then photoshop freeze and after effects did so. I quited all aplications and restarted. On restart after the 'bong' i've got the grey screen white an apple logo and a loading bar underneath, that was it, it never finished loading but shutting down.
After the 2nd try the computer gave me the BAD RAM alarm signal right before the start button was pressed and nothing more. I just managed to start it ONCE on safe mode, but this one also freezed and colapsed.
Today i didn't get the BAD ram alarm but the grey screen and loading bar after shutting down.
I took it back to the reseler, the shop boss who did the upgrade wasn't there , the guys on the morning shift placed the old RAM back resulting the same. So they told me it's a software problem, not hardware and might be caused by a failed firmware update or something i did wrong and since i was showed that the system booted after the upgrade i can't complain or argue that they did somethiing wrong.
So basically the want 80euros to check what's wrong with my computer plus the 120 i already payed them for a RAM that doesn't work and of course the repair cost of the computer.
On monday i'll go to talk to the boss, what do you guys recomend me to tell him? i'm frustrated that the guys there treat me like if i broke my computer for beeing stupid and wanted to get it fixed for free, when it clearly broke after they did something wrong on it!
please advice me!
thanks!

What brand is the RAM? From what you said, it is obvious that the RAM is at fault. I would simply tell them that it is not compatible and return the RAM.
Check the System Profiler to see what it says about the RAM (Apple Logo - About this Mac - More Info) and run this application to test the RAM:

If either shows any errors, print out the results and take them with you to the store.

Tecra A11-11N does not boot after CPU upgrade

Hi,
I would like to do a processor upgrade for my Tecra A11 11N from the i5-430M to a probably much faster i5.I thought the i5-580M would do, but the laptop did not boot when i installed this processor.
I reverted back to the 430M, did some research on the internet and found out that the 580M has a very high FSB speed and that is what probably made it not to work/incompatible with my machine.
http://ark.intel.com/products/43537/
http://ark.intel.com/products/49653
http://ark.intel.com/products/49652
and also at http://ark.intel.com/
Now i went back to the computer shop,returned the 580M and got an i5-560M as i compared it's specs and saw it would be compatible as it has the same FSB speed with the 430M.
I then later on in the day tried to install this cpu as an upgrade BUT alas!
It STILL WON'T BOOT ALSO.
I was left dumfounded.Processors in the same familly line are supposed to be compatible with one another provided:Lithography, FSB and socket type are similar.
Or what am i missing here?
I have done processor upgrades in many instances for both desktops and laptops and this is the first one that has left me with no words to say!
please offer some help/advice.

I solved this processor upgrade problem on my own.
I did some little research on what limits processor upgradability on computers and i
found out that BIOS was one of the factors that play a key part.
So,i went on a mission
to see if i could upgrade my BIOS and whether it would solve my problem.
I found this link to be very informative:
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=66624
I then downloaded the latest BIOS version for my laptop from this link:
http://uk.computers.toshiba-europe.com/innovation/download_bios.jsp
The following link gave me proof that the BIOS update would not bring any problems to my
machine and that there is already someone who had done it and not encountered any problems.
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=62459
Just to make sure that you are on the safe side,before carrying out the procedure to update
your BIOS,make sure you have a fully charged battery in addition to the AC plugged in.A power
outtage during this procedure would instantly kill your machine.
The BIOS installation took less than 3 mins.I copied the executable on the desktop and run it
from there.
On rebooting,the new BIOS was installed.The new BIOS version was 3.40 dated on 05/18/2012 while
the older one was version 2.0 dated on 04/03/2010.
From Intel's website,the i5-430M was released on Q1 2010 while the i5-560M and i5-580M were
released on Q3 2010.
It is pretty obvious that by the time BIOS version 2.0 was release,these two newer processors
had not been released and that explains why they were not being recognized when i installed them.
I finally swapped the 430M with the 560M,assembled back the machine and powered it.
Voil!,the machine booted to it's new life.Everything is as was before!
So far i have not seen any problems even to do with overheating or the cooling fan spinning any
faster that before.It is all the same as before.There is considerable performance gain with the
uprade.I am a software developer and my various development enviroments including compilers,
debuggers,database and deployment servers have all been running way way faster than they were!
I believe the 580M can also work but unfortunately i had returned it back to the shop.
There is no reason for buying new machines when we can upgrade the ones we have.What will
happen to the older ones?This means more electronic waste and so does new machines.Let us try
to make better use of the ones we have a in turn,SAVE OUR ONLY PLANET EARTH FROM GLOBAL WARMING!

Help Please - X200 will not boot after Bios Upgrade - keeps asking for power on password

Hi there,
I am new to this forum and please let me say a big Thank You for your help in advance.
I am using a lenovo thinkpad x200 running windows vista with service pack 1.
The laptop has always been running fine and has never given me any issues. Unfortunately, all this came to an end yesterday when I ran the system assistant which did a round of updates and it prompted me to reflash my bios.
I did what was instructed and closed all open applications and after the laptop restarted, there was a noise from the harddisk (the sound was basically like what happens if the harddisk suddenly loses power). Then, all i got was a black screen, no harddisk acitvity with only the power cable LED and another LED (with the shape of a N tiled at 20 degrees) on.
I searched the forum and did what was suggested in this entry: http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Blank-screen-after-Bios-Upgrade-on-X200/ta-p/29...
This is what I did so far"
I turned off the power, took out the backup battery and waited for about 30 minutes (repeated this step several times, also removing the harddisk) but to no avail.
I removed the RAM and tried booting and there was that characteristic beeping sound.
I replaced the RAM, redid the CMOS clearing, and now there is the Lenovo startup screen. However, there would be an error code 0271 (no date time) and 0251 (something about default configuration). Then, these disappear and all I am left with is the Bios Power On password prompt. Somehow no matter what I type nothing can be input into the field (and I did not create any password as far as I can remember).
I redid the clearing for the power on password by removing the backup battery as suggested at the bottom of this page http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-59377 but it is no use. Each time I restart, even if I press the blue Think Vantage button or F1 or F11, I still get the same 0271 and 0251 error messages and am left with the power on password prompt.
I am really desperate as I really like my lenovo x200 and there is important data on the laptop. I would appreciate any suggestions on how I can solve this. Its amazing how a simple update can turn into such a disaster. Now i know i should never upgrade or update my Bios (or at least proceed with extreme caution).
Anyone can provide some help to get my laptop workin again?
Thank you very much,
Mark

try reflashing your bios?

Not booting after BIOS upgrade in T500

I upgraded my T500 from BIOS 3.09 to 3.18 using the windows upgrade utility (6fuj42us.exe?). The upgrade went fine. I rebooted the machine and got the login windows screen (I have windows XP professional). However, the instructions of the BIOS upgrade called to enter into the BIOS and press the F9 key in order to set all the system defaults. After that the machine did not boot. It gives me the initial windows booting screen (windows flags) and then a blue screeen. I downgraded the BIOS to 3.15 using the bootable CD utility (6fuj39uc.iso?). The downgrade went fine. I can get into the BIOS but have exactly the same problem when loading windows. Unfortunately I could not find a similar bootable program for BIOS 3.09 only the windows executable program (6fuj34us.exe?). Is there any fix other than reinstalling windows? Thanks.

Hi malope,
please enter the Bios and check the HDD is switched to compatible mode instead of AHCI Mode.
Maybe than you can start Windows.

Macbook Pro is Not Booting After RAM Upgrade

Hi,
I just upgraded the RAM in my MacBook Pro running Mountain Lion from 4gb to 8gb (Using the memory that the guy at Fry's recommended). It has been stuck on the Apple logo for about 20 minutes after the upgrade, even after I made sure that the RAM was seated properly. Is it normal for it to take this long to boot after a RAM upgrade?

I installed 8gb (2 X4gb) and it has a maximum of 8gb. I have determined that it was just bad RAM, so I will return it as soon as I can.
Thanks.

Windows 7 not booting after memory upgrade ProBook 6540b

Hi
HP Probook 6540b
Windows 7 Professional 64bit
Currently, I have 2x2GB of RAM and I want to upgrade it to 2x4GB. After replacing the 2GB sticks with the new 4 GB sticks, the notebook does not start anymore. I bought the right kind with right speed (DDR3 1333MHz 10600 9-9-9-24 SODIMM) and BIOS shows the correct amount of memory but it gets stuck at "starting windows" screen. I've upgraded the BIOS to latest version... if i put the older 4gb (2x2) sticks back in there, it boots just fine. Memory was new and never even used. The memory diagnostics tool doesn't show any errors either, i.e. the test passes without errors.
Any ideas? Thank you for the help.
Regards
Martin

My new MacBookPro will not boot after an upgrade to Yosemite

I upgraded my brand-new (month old) MacBook Pro to Yosemite tonight, giving it plenty of time to reboot itself -- twice -- finally putting up the login screen.
After logging in, I noticed that the WiFI was off, and even worse, it would not turn on, so I rebooted it again.
After rebooting, it went through another long boot, with a thin slider showing progress, and then it showed the login screen.
I logged in, and then was able to manually enable the WiFi.
However, the system fan was spinning quite loudly. I checked for any 100% or more processes, but the system was actually quite un-busy. There was no reason for the fan to be spinning full speed. The office temperature is a very mild 71 degrees.
So, I did a Shutdown from the Apple menu and left for dinner.
A couple of hours later, came back to boot it, hit the power button, and .. no response. The MBP was plugged in with power, so it should not be out of battery. I tried holding down the power button for 10s and then 20s of seconds: no joy.
Does anyone know of a way to power up the system? I tried CMD-OPT P R with power button, 10s and 20s, but still no joy. The system appears to be completely, utterly dead.
At this point, it's looking like a "bricked" MBP, and I'll have to take it to the Apple store.
Very disappointed in this OS upgrade experience, and Apple's apparent decline in quality control since Steve has passed on. I guess no one is holding production's virtual toes to the fire anymore, eh?

Hey aks_sba,
Thanks for the question. There are a few more troubleshooting steps you can attempt before visiting an Apple Store, including resetting the SMC:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Laptop not booting after I Upgraded BIOS

Toshiba Satellite A215-S5849
Originally had issues with the left speaker making a horrible buzzing noise. Searching forums & help boards & the fact that I'm fairly computer Literate I came to the conclusion a OS reinstall was called for.
Since I only use this laptop for DJing theres only a couple of programs on it so it was not too much hastle.
Reinstalled OS Windows 7 updated it & all the drivers & the Buzz was still there.
This is when I read from a couple of users of Toshiba laptops said an upgrade of the BIOS helped them.
So I went to the official Toshiba support page & flashed my laptop using the following BIOS upgrade
ACPI Flash BIOS version 2.00 for Satellite A215 (PSAFGU/PSAFHU) 32/64-bit
Nearing the end of the flash my pc screen went black power lights are on, cord light on, battery light on just no OS
What I've tried.
Unplugged from power supply.
Removed Battery
Left for 20 mins & then tried to reboot.
Same thing happens each time
Power lights come on HD spins for a minute but nothing happens after that.
Any ideas why an official software update would cause my computer to not work & how do I roll back or clear my bios to default specs.

Finally I found a good Phoenix crisis copy at : http://mods.myftp.org/Tools/CrisDisk_and_Pen_Drive?_Recovery.rar
to download my own version of crisis disk with the new v2.0 rom bios. ready to build the floppy by running the crisdisk.bat:
http://rapidshare.com/files/410963513/CrisDisk.zip?.html
I posted this instruction to repair my A215 with these files:
Since finding a solution was a very confusing experience, here is how I fixed it (it should work for most similar models.)
Now read it all the way through because the steps are critical.
I got a Toshiba Satellite A215 PSAFGU (S6814) And after shutting down from overheating during a flash from windows it didn't boot. Black screen and nothing more. Meanning my bios was corrupt
So after lots of trial and error, using an external usb floppy drive I managed to save my laptop.
Maybe people here describe how to do it, but they tell you to download the wrong crisis recovery files and once you try to use your ROM instead of the one on the disk, or try to replace phlash16.exe it just fails. Tried injecting but that didn't work.
Finally I found a good Phoenix crisis copy at : http://mods.myftp.org/Tools/CrisDisk_and_Pen_Drive?_Recovery.rar
unrar and go to the directory, then unrar (you'll see it) CRISDISK.rar .
This copy of crisis with phflash16.exe (in the extracted directory) is a good version that can handle the newest versions of bios ROM.
Now copy your ROM file to the crisisdisk directory renaming the file to bios.wph and thus replacing the existing one.(i used the new 2.0 version ROM from the Toshiba site - in this case its called m10a200.rom)
To prevent 'dos path' errors when building the disk, copy the entire directory to a simple one like c:\cirsis
Build your disk now by running CRISDISK.BAT - the process includes quick formatting, copying the three files, and lastly making it bootable, make sure you go through all the steps. ( at first, i messed the last part by not having it bootable and it failed ofcourse)
once it says it created the disk successfully, put it in your external usb drive (or use the disk you created to make a bootable flash drive by using hp drivekey boot utility available here: http://h20000.www2.hp.com/bizsupport/TechSupport/S?oftwareDescription.jsp?swItem=MTX-UNITY-I23839 I didn't have a chance to test it with usb flash drives, but it should work.)
Now once you connected your media to the usb port on your laptop:
make sure the battery is out, power cord out, hold fn+f, while doing that, plug the cord and then push the power button, release the fn+f key once you see the light on your usb drive/usb floppy is starting to blink. it should pause for a few seconds, and then start reading the disk for a while (not just 3 seconds). Process should not take more then 10 minutes so waiting more then that is a waste(trust me). The computer should reboot byitself if everything is fine. Mine took about 5 minutes but give it 10 just to make sure.
After hours of finding, replacing, injecting, only this worked.
This works for sure, if you follow these instructions with your Toshiba Satellite A215. Don't loose hope - you will recover it.
A good sign is when using the fn+f method and it flashed the usb drive/floppy. It means its 99% recoverable.
Really hope this saves time for others.
This is a solution posted by yarivc on the USA Toshiba site.
http://laptopforums.toshiba.com/t5/System-Recovery-and-Recovery/Toshiba-Satellite-A215-S7422-bios-crisis-recovery/td-p/69185
BTW
to the last poster
If you were to ask 100 customers in any comp store who just purchased a Toshiba Laptop if they knew a OFFICIAL UPDATE from the manufacturers support website would VOID a warrenty I gaurantee not one of them would know that nor be impressed by it.
Further more what screwed up my bios was not the BIOS upgrade but the fact that Toshiba has a install from your desktop (windows) button in the update, researching this I found that one should never use this method because Windows in inherently unstable when it comes to BIOS update.
This option should NOT have been included in the update since its very unstable to do so.
On a side note.
My left speaker buzzing noise is back. But it doesnt seem too annoying right now concidering I saved myself money & headache.

Anyone knows what's going on? Please help!!!!!!

Well the people at Apple have no way of knowing if you have a marginal hard drive, or something installed that would interfere with the update from a third party. Problems can arise especially from tools such as system cache cleaners, anti-virus, firewall, and other software that operates in the background.
http://www.roaringapps.com/ should help you know what is compatible if you are running 10.7 or later.
In the future ignore push notifications, and turn them off via the Apple menu -> System preferences, Software Update, and the App Store preferences.

Already have the latest Firmware (Efi and SMC) for quite a long time, can`t reinstall it or downgrade it (due to apple.). Apparently CD firmware restauration not available to my model ( original installation cd don`t work beacuse it is a previous version of firmware?)
What else can I do?

Wrvs4400n not stable after firmware upgrade help!!

Hi,
I need some help.
System:
WRVS4400N wireless router
Firmware 1.1.03
IPS: 1.31
I went through LinkSys site and downloaded the new firmware and ips signature listed above. I upgraded my system a few days ago and having alot of problems with disconnection through the router. I would have to reset my wireless router every so often since the firmware upgrade. Most of the time, it would take one tries but sometime i would have to unplug and plug the router's power cable many times before having internet access. My previous firmware version i believe is 1.0.06 and it was working fine except that my MAC OS X wasn't able to connect via wireless connection. That's why i decided to proceed with the firmware upgrade. Now, the new firmware is giving me a whole new problem and unfortunely i forgot to back up my previous system's config (firmware).
I am sure this problem is not caused by my IPS or the modem because when the connections get dropped, i was able to connect directly through the modem. I am not sure if others are experiencing the same problem, but at this point, i think this is some bug on the new firmware. Please i need some solution to this. Any advice or suggestions?
Thanks

There is a Recovery program for recovering from the latest firmware "upgrade" that borks the router. The latest "firmware "upgrade" completely trashed my router. I could not even connect to it from its internal IP (192.168.1.1) to attempt to downgrade the firmware. Nice of Linksys to allow people to go through an upgrade that trashes their router. Then to make matters worse, the Receovery program only works in windoze, so I had to find a windoze machine to use to downgrade the firmware. What happens if you run Linux - out of luck. Long story short, why not have some kind of warning on the firmware upgrade that unless you first do the recovery firmware flash, you can kiss you router goodbye for the time being.

Leopard won't install on PowerMac g4 AGP graphics

Leopard won't install on PowerMac g4 AGP graphics (2) which was pimped to 1.5 ghz with Sony dual power drive with 100 GB internal HD currently happy running on OS X 10.4.10 Tiger, the rest of the G5s (6) was upgraded bautifully. Again anybody out there with slick idea on how to deal with this leftover G4. The Leopard disk simply say " OS X 10.5 can not be installed on this computer" end of story if we insist on trying other ways the machine simply blank-out ( you know the dreaded question mark and the happy face folder).

Need opinion : Tiger Server running on PowerMac G4 (AGP Graphic)?

Dear Gurus,
I have a spare PowerMac G4 (AGP Graphic) with 2GB RAM, and a spare copy of 10.4 Server. Is it reasonable to install Tiger Server into this PowerMac? The computer will serve as a file server for about 20+ user (mostly documents, no video or gigabyte psd file).
The machine meet Tiger minimum system requirement but I need some real life opinion of whether this is okay, or just a bad idea (system will sluggish, etc, etc.)
TIA

Server doing File Sharing is an I/O problem, not a compute problem. I have run Server 10.3 on a Beige G3 \[with a SCSI RAID added].
You need fast Hard Drives and a fast (preferably Gigabit Ethernet) connection to the workstations to get "near Hard Drive" performance.

Mac Mini will not boot after Security Update 2008-007

Hello,
A G4 Mac Mini machine I was asked to take a look at will not boot after the owner (succesfully) installed Security Update 2008-007 from Software Update. Booting always hangs at the blue screen after the Apple logo, and booting in verbose mode reveals that WindowServer is crashing repeatedly. Permissions and filesystems have been repaired, PRAM reset, etc. Safe boot also exhibits the same problem, but it is possible to boot to single user mode. Hardware checks out fine with diagnostic utilities.
Any suggestions on how to fix this? Unfortunately, backups are not available (it's not my machine =).

Hi Arkku , and a warm welcome to the forums!
I'd certainly give Sig's advice a try first.
