FireWire - USB 2.0 Neither 1394 nor USB were ready until about 1998. There were USB connectors on boxes, but no peripherals avaialable. Bios changes were required to enable USB on early machines as the protocol changed several times even after the chipset was finalized. Windows 98 was the first system that could run USB 1.0. Firewire (1394) was not intended to replace SCSI or other internal connections. It is primarily a high speed peripheral connect for devices "outside the box". It currently is ready except for 2 things. 1) No native support in Windows. 2) No access to the CPU through a high speed connection. Both of these were planned and were in the PC98 and PC99 specs. It was not until the Sony chipsets were released which enabled 1394 devices to communicate peer to peer that USB 2.0 was substituted. Do you remember when PCs used 5 1/2 inch diskettes? IBM came out with a high-density version of the diskette which was "backward compatible". Of course a high density floppy which looked the same wouldn't work in a low density drive, and a low density diskette formatted on a high density drive would no longer work in a low density drive. Often the failures were intermittent. A similar confusing array of "backward compatible" cables and products are about to be thrust on the consumers. Any existing "low density" USB cables will fail (or intermittently fail) on "high density" peripherals even if connected to a USB 2.0 port. Of course these cables look exactly like the high speed cables. New periferals connected to older machines will not work properly even though all the parts fit just right. It's going to be a mess, and it doesn't have to be one. TP
