FireWire's speed limit with PCI and PCI Express cards

Hello, All.

Something I don't see in this article, which I'd like to know about and which might properly be included in the article, is what the speed limit is when a FireWire card is connected to a motherboard's PCI or PCI Express slot. I don't know much about this, but am getting the impression that the 400-Mb/s speed of FireWire can't be achieved through a PCI connection (because that connection's top speed is nowhere near as high as 400) but can be achieved through a PCI Express connection (because that connection's top speed can be at least 400).

Does anyone here know the answer? And where in the article might we include such information?

Thanks.

Wouldn't that be a limitation of the PCI cards, and not FireWire? If you want to mention it, it would probably be better mentioned in the PCI article than the firewire, since it has nothing to do with the firewire it's self. Hanii (talk) 09:52, 1 April 2009 (UTC)

Even the original 33Mhz Conventional PCI which pushes a sustained >1000 megabit/sec is perfectly capable of keeping up with Firewire's 400 or 800 rate. Now if you had an ISA based FireWire card... -- KelleyCook (talk) 14:09, 1 April 2009 (UTC)

does firewire need software

Does the fire wire need a software or computer's automatic reconized it? —Preceding unsigned comment added by 12.155.58.226 (talk) 14:18, 12 May 2009 (UTC)

usage errors in this article

Several times this article refers to "four circuits" or "six circuits" which I believe is incorrect. Firewire 400 connectors can be said to have 4 or 6 pins, contacts, or conductors -- but not 4 or 6 circuits. A circuit requires two conductors. —Preceding unsigned comment added by 74.92.152.108 (talk) 17:01, 4 September 2009 (UTC)

SCSI capabilities

The article says: Perhaps more important, FireWire uses all SCSI capabilities. But the sdparm utility page says that IEEE 1394 only supports the Reduced Block Commands (RBC) set.--Sergei (talk) 07:09, 18 November 2009 (UTC)

"purchase newer machines which map a virtual memory space to the FireWire "Physical Memory Space" (such as a Power Mac G5, or any Sun workstation)" this sections seems out of date, it should be updated and/or clarified.
