I'm looking for a compatible IDE/SATA adapter to put a hard drive or SSD in a Power Mac Quick Silver.
I've tried two, but I can't install the system.
If anyone knows of a working adapter, please include the make and model. Any eBay links where I can buy one?
Or if anyone has one for sale?
I live in Italy.

The ultra cheap one I bough ages ago just worked.

But....

I would advice getting a SiL3112 SATA card (10€ or so) and
... either flash it with a PPC/Apple BIOS
... or leave it as is and boot from a CF card hooked up to IDE

I did the 2nd option as it allows you to have the SATA SSD with an RDB and that setup even worked for Linux.

You could even keep a spinning HDD on the IDE as all you need there is a place to put the boot.img.

Could you explain this better with a GUIDE?
So just one partition for the boot.image file and then any connected hard drive?
I don't quite understand. I'd like to delve deeper into this.
I've been using Morphos since the first version for Mac Mini and I'm quite knowledgeable about Morphos.
These IDE drives have become very rare in 2025!
But an IDE-SD adapter might even work,
even just for booting, and then I'd use a secondary hard drive.

Basically you just install MorphOS to the CF card or IDE HDD as usual (even a 1GB CF card will do that trick).

Next you install the SATA card and drive, partition it the way you like it and make one partition bootable.
(make sure to have none clashing drive and device names).
Run the installer again with the SATA drive as target.
Put the SATA drive at a higher boot-priority and "put away" the partitions on the CF card to unclutter your Ambient screen.

System should now boot from SATA.

Here's something I did for 2.5" PATA drives so I could get cheap SSD to Mac Mini G4 and PowerBook G4: https://infosec.exchange/@harrysintonen/110860104802345898

I've never looked into 3.5" PATA solutions though, but I guess you could always just add 2.5"<->3.5" adapter, or maybe there's some adapter that does the same with 3.5" drive connector directly.

Get the DIGITUS DS-33151-1 IDE TO SATA CONVERTER. I am using it on a PMAC Sawtooth along with a ADATA SU630 240GB. Works perfectly. I have tried to use it with an even bigger ADATA (480 or 512GB, can't rememeber) but it wasn't recongised. Perhaps because in the meantime I installed a second regular (IDE) drive 320GB, idk. But anyways, above combo works really nice and maxs out the bandwidth.

G4 PMacs have OF limitations on HDD size. The older the model/OF the smaller the useable drives get.

That and the limited speed (ATA66) is why I recommended going with a PCI SATA card + small boot drive.
