I managed to create a network bootable disk image on my 17-inch iMac. I then used that image to simultaneously boot both my 2006 Intel iMacs as diskless network clients off of a PowerPC G5.
I don’t want to sound daft….but I never knew this was possible…. 😁
Very cool.

I found two sil3512s ina box of pc stuff in my garage that I didn’t realize I had so I pulled out my B&W and flashed them both with the Weibetech firmware flashing utility I pulled of WBM.

Worked fine on the B&W. For some reason, the utility spits out a memory error on my Graphite. Anyways, yet another reason to keep such a Tempermental PITA box as a B&W around. I also picked up another Orico SSD sled (2.5 to 3.5) and stuck that in my a1117 so the 2.5 drive isn’t flopping around in there anymore lol.

Never a dull moment putzing around with my PPC stuff. :)

Speak of the devil. Mr.Postman just dropped off the new dvd drive for my kids 2009 iMac. They burned out the old one playing Sponge Bob & Home Alone DVDs lol

So glad that I'm not the only person to think this. Much as I love my B&W, heck I forked out and bought it a G3 1Ghz upgrade only a year or two back. I have to say that since owning a Quicksilver, I have quickly become aware of what a PITA it really is. I love how it looks, I love that it was my first ever G3 back in 2005. BUT it gives me more headaches than any other machine I own. It's the karen of my computer collection. I've not had it turned on since last year, I know for a fact if I were to drag it across the room and turn it on now. It wouldn't boot, until I've laid on the floor, removed each dimm stick, reinserted them, took them out again, placed them in different slots, flashed the pram, THEN placed them back in their original positions only to see it boot up. I'm amazed I actually have any hair left lol

The QS hadn't been powered on since last Nov and it just worked when I fired it up a few weeks back.

The SATA cards I bought are just generic cards I bought off ebay which have been pre-flashed by the previous owner, who may or may not be on this very forum lol One of the cards boots OS 9 and I think the other only boots OS X, I know one only has a single internal SATA and two external, while the other has two internal ports. Which is the one I was planning to use on my QS.
 
I hear ya man. Part of me loves this B&W but a big part of me just wants to kick it across the room when it gets pissy.

This made me LOL. Perfect description of this box :D

Every weekend I boot up my original iMac G4 and my 12" PowerBook G4 to know that they're alive and badly obsolete on the software side. It's reassuring.

Well a couple of days ago I fired up my 1st Gen Firewire iPod, just to confirm it's still alive. I mean it should be as I replaced the battery in it not that long ago. The annoying thing I had was it repeatedly locking up or just down right not being recognised by iTunes on the QS. I got it in my head that perhaps I had sync'd it on another machine, yet the QS was allowing me to see it and alter it's contents (when it appeared and didn't lock up that is). I pulled out my G4 iBook, which I know does work with that iPod, as I'd previously been using that as my daily machine until a few years ago. Sure enough it appeared in iTunes, works fine. I took it back to the QS and what do you know, works the moment it's connected SOAB!

Over the next few days I think I'll fired up my Pismo and G4 Powerbook, just to top up their batteries and make sure they're working. I miss using the Pismo, loved the keyboard.

The B&W is sat beside the door to my office, I upgraded it last year from a G4 500mhz to a G3 1Ghz and honestly it wasn't wort the effort or the money. Sure it's a little faster, I can make it on here even. But overall it isn't mind blowing, gee wiz that's fast! In fact, since I fitted the darn G4, it has become super picky over ram and will NOT accept 1gb of max ram. I'm not sure if there's a hardware limitation I'm not aware off, but no matter what I do, it does not want to boot with a full bank of 256mb sticks.
 
I downloaded your R-gui port and I am rlly impressed because you managed to build it with Aqua interface. How did you do that? Could FileZilla be build using Aqua?

Fixing the code was trivial, just revert a couple of breaking commits: https://github.com/barracuda156/R-GUI-PPC/commits/powerpc
XIBs are forward-ported from some earlier version (portfile has exact details). In principle it is probably possible to take modern XIBs and sequentially re-save them in older formats in several Xcode versions down to 3.2.6, but I never wanted it that much LOL

I never even looked into fixing Cocoa in FileZilla, tbh. From what I understand, it uses wxWidgets in any case, it is backend which varies. Native backend in wxWidgets builds but does not work correctly (menus are not clickable) up to 10.8, I think. If that bug is fixed, chances are it gonna work.
 
Today, I upgraded my Power Mac G5 DP 2.3 GHz from 4.5 GB of RAM to 8.5 GB of RAM, running before and after benchmarks using GeekBench 2.2.7.

Here is the memory configuration before the update:

2025-03-19.02, Power Mac G5 DP, 4.5 GB RAM Configuration, System Profiler.jpg


and here is the memory configuration AFTER the update:

2025-03-19.03, Power Mac G5 DP Memory Configuration, 8.5 GB, System Profiler.jpg


You will note that the new RAM, although sold as, and labeled as, PC2-4200U, is recognized by the Mac as PC2-3200U, and hence is presumably accessed at a slower speed than the PC2-4200U RAM.

Happily, this was not the case, or if it was, it did not impact system performance.

Prior to the upgrade, the GeekBench 2.2.7 RAM score was 1693. After the upgrade, the same score was 1730, actually FASTER despite the slower RAM. I am a bit perplexed, but happy nonetheless. It annoys me that the new RAM was recognized at a lower speed than what it was sold as, but it has clearly not impacted system performance.

One other "side effect" of the upgrade. This machine used to idle at about 38 C. Now it idles at about 47 C. That new RAM must throw more than a little heat! The CPU fans actually seem to be running at a slower speed than before, which is also perplexing, but may in some measure account for the higher idle temperature. At any rate 47 C is well within the "safe zone" for the PowerPC 970MP. If I *ever* succeed in getting my G5 Quad to idle at 47 C I will declare victory and be done with my seemingly endless work on the Quad's Liquid Cooling System (LCS).

Looking for some troubleshooting advice... I'm trying to bring a rev 4 trayloading iMac G3 back to life, but I've hit a roadblock. I originally thought the CD drive was dead, but I finally got it to boot a 9.2.1 install disc (slowly, the drive is dying) only to find out that it doesn't identify the SSD I was planning on using.

I'm using the red Startech IDE->Sata adapter board (which seemed like the one everyone recommended) along with this Transcend 32GB SSD. I connected it to my M1 Mac Mini and formatted it into MacOS Extended partitions, one 26GB and one under 6GB. The adapter pins are jumped to Master and the CD drive is also set to Master. When I get into the 9.2.1 installer, it only detects the disc and not the drive. Is my formatting wrong somewhere, or do I need to go scrounge up some other hardware?

My gut says its something about the SSD. Lotsa folks use the startech adapter without issue. Just to check, when you created the SSD partitions, did you set the partition table to APM? PPC macs should still be able to see it if you set it to guid but as a boot drive, it would have to be APM. I have had a few SSDs (they were Netac branded) work fine in Intel macs but not show up in a PowerPC mac - upon further research it was an upgraded controller on the ssd that caused the new ones to not be detected. If you have a sata spinner somewhere you could stick that onto your adapter (set to master of course) to see if classic sees it. Conversely, if you suspect the adapter, you could test it in another computer.

About the DVD drive. Suprisingly, I was able to connect an external superdrive via my tray loaders usb1.1 and use that to boot/install optical media from. I did not expect that ro work LOL. It was usb1 speeds, so sloooooow but it did work.

Wow, good to know about the drive. I've gotten into 9.2 setup three times with my disc and two out of three times it was dog slow, but the other time was actually kinda snappy. I'm hoping the built in drive has enough life to get this OS install done and then I can work around it with USB.

I did partition table to APM. I don't have any other drives handy and the only thing that might have one is an early Intel Core 2 Duo Mini, but I don't want to take that apart if I don't have to... Might need to go find a new SATA disk then :/
 
After 03/23/05 and before 07/12/05, Apple added GPT support to Open Firmware (maybe OF version 4.9.x for 32-bit Macs or 5.2.x for 64-bit macs). It might allow booting Mac OS X from GPT? 2005 is the last year Open Firmware was updated.
 
Woke the machine up from it's winter-sleep.
Read the Chimera thread and alubook133's ongoing adventures = Everything was the same
Put the machine back to sleep for another year, to see if the adelielinux-people has got a working install

An update on the above. The machine is back to idling at about 36 C now, but I think the fans have ramped up a bit to accomplish this result. The machine is still not particularly noisy - the CPU intake fans are running at 1455 RPM now; they were at a lower RPM level... I think!

Anyone else with a Power Mac G5 DP 2.3 GHz, what are your idle temperatures and fan speeds? Thanks!
