I just installed a 120 gig ssd in my G4 Digital Audio. I ordered a Sonnet Tempo Sata PCI, and a cheap IDE to SATA bridge as a backup...and the cheap bridge worked while the Tempo failed
Actually, the Tempo worked once when I first installed (booted to OS9.22). But now (with the card installed) the Mac doesn't even boot to CD or a good IDE drive. It does chime however, indicating the hardware is good. I take the card out, and the cheap bridge works great.
I contacted Sonnet support about whether the Tempo card will only boot from the card when it's plugged in (no response yet). So, I went to plan B (cheap sata bridge) and I am in business, but, the Tempo is a paper weight.
I was thinking about putting it in my pc to see if I could at least see it, and possibly downgrade the firmware (if required). Does anyone have any experience with this card?
