Asus a7n8x deluxe 1394 problem

Ok Here it is ( found in SP3 knoledge base ):
if you add a host controller for a new 1394 device to your computer,
you must add or modify the SidSpeed entry in the Windows registry for
the new 1394 host controller. To do this, follow these steps:1. Click
Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\P CI\1394_hc_hw_id
\1394_instance_id\Device Parameters
3. If the SidSpeed value does not exist in the right pane after you
click the Device Parameters subkey in step 2, create it. To do this,
point to New on the Edit menu, click DWORD Value, type SidSpeed, and
then press ENTER.
4. Right-click SidSpeed, and then click Modify.
5. In the Value data box, type one of the values that are shown in the
following table, and then click OK.Value Speed
0 S100 speed
1 S200 speed
2 S400 speed (default value)
3 S400/S800 speed (Windows XP Service Pack 1 [SP1] value)
Note If you try to use a value that is larger than 3, SidSpeed will
use a value of 0 (S100 speed).
6. Quit Registry Editor.
To locate the FireWire controller information, follow these steps:1.
Open Device Manager. To do this, right-click My Computer on the Start
menu, click Manage, and then click Device Manager under System Tools.
You can also click Properties under My Computer, and then click Device
Manager on the Hardware tab.
2. Locate your FireWire controller in the IEEE 1934 Bus host
controllers section.
3. Right-click the FireWire controller entry, click Properties, and
then click the Details tab.
4. Click Device Instance Id. You see a string of letters and numbers
that is similar to the following:
PCI\VEN_104C&DEV_8020&SUBSYS_00D81028&REV_00\4&19F D8D60&0&60F0
The information between the two slash marks (\) is the
“1394_hc_hw_id". “VEN_104C&DEV_8020&SUBSYS_00D81028&REV_00” is the
hardware ID in this example. The information that follows the second
slash mark (\) is the “1394_instance_id”. “4&19FD8D60&0&60F0” is the
instance ID in this example.

This text tells you what that information applies to -

"This problem occurs if you connect a 1394a or 1394b
FireWire device to a *1394b* port. This problem occurs
because Windows XP *SP2* changes 1394b ports to S100
speed when you upgrade."

The A7N8X Deluxe has a 1394a, and it is based on a
controller in the chipset, plus a RealTek PHY chip
to drive the 1394a ports. So there is no need to
change the registry. Just plug and play.

There are fewer boards with built-in 1394b ports.

Agreed. The 1394a (aka Firewire 400) port on the A7N8X deluxe only
needs the drivers included with XP and doesn't need any special treatment
or downloads.
XP can also use it as a network port - I use that to connect 2 PCs on my
network and get terrific throughput - network drives operate almost as
fast as local drives.
