PCIe Storage in Power Mac G5?

there were some "oem" silicon 3132 that could be used with the G5 (I don't know if it needs flashing)

If you want theory, here it is:

First revision of Revo was using Sil3124 controller. There's a 10.4 and 10.5 PPC driver for this chip, so theoretically it could work.
However, there's also PI7C9X130 bridge chip converting PCI/PCI-X signal to PCIe. If it's transparent for OS, Revo will work. If it isn't - it won't.

 

Big question is, is it bootable on a PowerMac G5? I am guessing it is not. If it will work on Leopard it means that it is only good for storage?

 

100% non bootable. It isn't even in MP.

 

Revos are cheap nowadays, esp. first gen., so maybe it's worth to try.
I think that this bridge chip is transparent for OS.
Ensure that you're buying Sil3124 based one.
Drivers are available on Silicon Image website.

 

AMCC 3ware 9650SE line is 100% compatible (also sold under the brand LSI). Driver's are found on their website. It is not bootable, though. Fun fact: it uses a PowerPC chip on the card.
