Only get a PC Radeon card IF you have a PC or bootable Mac with alternate video so that you can flash the Radeon ROM (BIOS in PC speak) to Mac. This might be too complicated for you, I can help, and it doesn't take too long if you know what you're doing, but it's a hassle. If you don't have any way to flash a cheap $10 PC card you'll be stuck having to buy a Mac card. Someone might sell a Mac card cheap on LEM-Swap list if you place a WTB? I will buy a PC card.

Dual 2.0ghz G5 won't boot after being unplugged overnight....
Yesterday we had a thunder storm and when leaving my office I not only turned off my power strip that our (G5 DP2.0ghz, 4.5gb ram) computer was plugged into, but I also unplugged the power cord from the strip/surge protector. I usually just turn off the surge protector when we have a storm, but after my father's G4 lost it's power supply after a bad storm a couple weeks ago, I decided to unplug the cord as well. This morning it chimed but soon stopped everything at the gray apple screen. I held in the power button to shut it down and after trying again it chimed and then the light above the power button now just blinks 3 times every 5 seconds or so. Then the chime went away and it just blinks 3 times as mentioned. I wanted to do a pram reset however it does not chime. I tried replacing the pram battery but it still does this blinking thing. I assume that is an indicator of the problem and am hopeful someone here can help me get back running again.

Yes, although I've never gone as far as soldering a new ROM chip onto a card. If the ROM is the smaller size, there is a special reduced size ROM file that works in the smaller ROM chips. Also, there can be some problems with the speed of the physical VRAM on the PC cards which in rare circumstances can cause video glitches. This can be corrected by using a custom ROM file, or adjusting the ROM clock in software using ATIcellerator II. I prefer the custom ROM if this is necessary. The Mac Radeon 7000 only came in a single version which has 50ns (ns=nano second) VRAM chips, which correspond to a clock rate of 183 MHz. The Mac ROM normally sets the GPU Bus speeds to 183 MHz. The PC cards came with a variety of VRAM chips that vary from a slow of 75ns, but also come in 70, 60, 50, 40, or 35ns speeds. If your card has chips that are SLOWER than 50ns (i.e. 75, 70, or 60ns) there will be video glitches artifacts because the clock rate of 183 MHz will be too high for these slower chips. Sometimes it's not a problem, it's like overclocking the slow chips, and sometimes they overclock OK, but if not, you can either create, or download, a slower ROM. There's a 166MHz ROM common for download that will normally fix this issue. The VRAM chips have a # printed on them, and there is a - at the end of this # followed by the speed in ns, so the number would be something like -50 if the chip was a 50ns chip, and -35 if it was a FASTER 35ns chip. Since 50ns is the standard Mac chip, it always works. If the chips are FASTER (i.e. 40 or 35ns) then you can safely overclock the card to a higher clock rate, probably 200MHz, or maybe even 225MHz. There's no need to overclock, the faster chips will work perfectly with the standard 183MHz Mac ROM, they will run cooler and effectively be underclocked. Most likely you won't need to deal with this aspect of custom clock rates and can simply flash the card with a standard Mac ROM and it will function fine. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: screen saver photos
Thanks for the suggestion, but I chose a different folder. left SYST PREFS and then went back in and reset to teh one I want no difference, On Sep 26, 2012, at 12:05 PM, Dan wrote: At 2:39 PM -0400 09/25/2012, JohnV wrote: G5 1.8 dual running 10.4.11 on 2 monitors I have a folder of pictures that cycle through the screensaver slideshow thing.

Re: G5 Repair - Next step?
Hello MJoeYoung, Thank you for the help and link for prospective parts. Here is what I did recently: replaced the PRAM, swapped the CPUs (A to B, and vs. a vs.) made sure the CPUs were well-seated. Of course, having to take apart the G5 (not as bad a project as I thought), that gave me a chance to reseat everything. I also inspected the board - no noticeably bad elements, though I suspect the ROM chip may have gotten fried (I have no actual evidence to this effect, just a gut feeling based on the way the unit boots up. Thank you for the link. The motherboard is less in $$ than anticipated, so, I need to decide to invest a little in the hopes that it offers the cure, or simply give up and part out the unit. Thank you again for all your contributions on this project. Dana On Sep 25, 11:40 am, mjoeyoung mjoeyo...@gmail.com wrote: I want to confirm that you switched CPUs (A in B slot and B in A slot) and that they were both seated properly when you turned the computer on. If CPU A is bad and CPU B is good putting CPU B in the A spot and CPU A in the B spot should allow the computer to boot. Both CPUs (even if one is bad) need to be installed for the computer to work. When I was fixing my problem I had both issues (unseated and only one installed). One of the earlier G5s was able to run with only one CPU installed in a 2 CPU system so you could try that, but I think it was an earlier model to yours. Have you replaced the battery? That can be the cause of various issues. I do not know of any motherboard checks except for visual inspection of bad capacitors. If the computer is making sounds and the fans eventually go into wind tunnel mode I would think the power supply is probably okay. The chance that BOTH processors went bad at the same time seems slim. So, I would guess logic board. I fixed mine on a whim just to see if it was possible before getting rid of it. These computers are so cheap now that it is almost not worth the time/effort to repair them. This is the storehttp://www.electronicscafe.com/ I purchased my parts from. They also sell on ebay. They have a motherboard that might work for about $17 and a pair of cpus for $25. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
