Powermac G5 no SATA
Posted by: alan on 2019-08-16 12:59:13
hello all

I have managed to get an old but nice looking G5 about to be binned. Its a 1.1 version 2x 2.66 I think processors. 2GB ram

It was missing a graphics card and side panel.

Got an ebay special radeon5770 card and now I get a display

I managed to get a OSX leopard install ISO and put it to USB and booted from it. Reassuring 'dong' boot up sound and all.

I get into the OS install screen but the hard disk doesn't show up. Ok so I took it out and tried it on my PC and the HD was FUBAR. So I have a few older HD's which I attached to the mac.

I tried a

80 GB WD800 sata 1 drive

a 1.5 gb sata 3 drive

a drex  X1 sata 3 60gb SSD

nothing appears in disk manager, bar the USB install 

The optical drive randomly appears but will not respond to OPEN commands or manual button on front. Green light always lit.

I removed the optical drive but the sata HD's still don't show up

so it looks like the sata interface is duff. I checked the power connectors and there is 12v ok.

is there a PCI SSD arrangement I can get to work?

it would be a shame to scrap this machine but I don't want to spend lots of cash in buying stuff if at all possible

any help much appreciated as I am a complete MAC noob

Is this a Powermac G5 or a Mac Pro? 1,1 and the speed rating would indicate first gen Mac Pro with INTEL processors. 

If so it has pcie slots, not pci. Either way, mac sata controller cards are available, for intel or ppc. But please confirm your exact model before buying anything...

I haven't heard of the SATA interface going on these, but it's not impossible.

There are SATA cards that should work, but mounting a replacement drive will be annoying. A card with one or two SATA m.2 or mSATA connectors should work, but this machine is unlikely to be able to boot from NVMe disks.

You can install the OS onto a USB disk to get started. That will get you booted into Mac OS X, which also gets you system profiler, and you can see whether the SATA chipset itself shows up.

Mac Pros were built when Southbridge chips were still used to control storage, ethernet, usb, sound etc so are any of those non functional as well?

I have a PC that works fine except the motherboard SATA do not work at all (nothing detected), I just assume that part of the southbridge is defective. Storage is taken over by a 3rd party PCIE SATA card.
