My mail to Creamware:
On the Apple website you can read that you can choose between PCI or PCI-X.
The PCI slot can be used for 5,0 V cards but only at 3,3 V signaling. Can I use my PowerPulsarII cards with such slots ?
Knowing that you are investing time and efforts for providing us with an OS X version of SFP, your answer is critical in my decision of buying an Apple Power G5 Dual 2Ghz with PCI slots rather than a Power G5 2,7Ghz.
I love your sytem but I want to move completely on Apple.
PS: hereunder the details about PCI and PCI-X

About PCI Expansion Cards
Your Macintosh has three expansion slots, labeled 2, 3, and 4, which can accommodate expansion cards up to 12 inches long. Depending upon the model of your Power Mac G5, you can install either PCI or PCI-X cards.
Maximum power consumption for all four expansion slots (the three PCI expansion cards and the AGP card) should not exceed 90 watts (W).
Card type supported Slot Card speed
PCI slots 2, 3, and 4 64-bit, 33 MHz
PCI-X slots 2 and 3 64-bit, 100 MHz
slot 4 64-bit, 133 MHz
The PCI slots can accomodate mixed-voltage (5.0 V, 12 V, or 3.3 V) cards, but only at 3.3 V signaling, with 32-bit or 64-bit data widths and a 33 MHz frequency. You can add a 66 MHz card to a 33 MHz PCI slot if the card can operate at the lower 33 MHz rate.
Warning: Do not use PCI cards that function only at 66 MHz in the 33 MHz PCI slots. Damage to your equipment could result. If you have a 66 MHz PCI card, check with the card's manufacturer to see if it also works at 33 MHz.
