Step-by-step procedure to install mobile Catalyst control center for x1700
Officially there is no support for x1700

, but with proper changes it is possible to install the mobile catalyst control center 7.1 on x1700 Card!
You can either download the file I prepared from here:
X1700 Catalyst Installation Guide by Turbogear
OR you can do it manually as described below.

This can be done as follows:
(1) Download the Ati driver "Ati Mobile Catalyst 7.1"
(2) Unpack it. That can be done as follows.
Try to install the driver. It will unpack itself into a folder "C:\ATI\SUPPORT\7-1-mobile_xp_dd_ccc_enu_40212"
Of course it would not be installed since it say that the X1700 is not supported.

Now do the following steps to make the x1700 supported by "Ati Mobile Catalyst 7.1"
Every device has so called Real Device ID and that should be added to the installation routine.
The Mobility x1700 has the ID: 0x71D5 and this should be added to "install.ini" as demonstrated here:
(3) Open the "Install.ini" file with an editor. Usaully it is in folder "Driver" (normally in "C:\ATI\SUPPORT\7-1-mobile_xp_dd_ccc_enu_40212\Driver".
Look in the section described below and add the x1700 ID there so this section would look as follows:
[WINXP]
Label=R6
R6=DriverPath_R6,0x71D5,0x4966,0x496E,0x5961....
Save the file and exist.
Note: This is the procedure for windows xp. If you want to do it for other version of windows than you would have to edit the approaperiate section.
(4) Do the same procedure with the file "CX_40214.INI" which is also located under the same folder.
The windows xp section in this "CX_40214.INI" file should look like below after adding x1700 ID:
[WINXP]
Label=R6
R6=DriverPath_R6,0x71D5,0x4966,0x496E
(5) Change to the folder "XP_INF" (normally "C:\ATI\SUPPORT\7-1-mobile_xp_dd_ccc_enu_40212\Driver\XP_INF").
Open the file "CX_40214.inf" with an editor.
Now comes the part where most of work needed to be done 
Search inside "CX_40214.inf" file (with ctrl+F) for the entry [ATI.Mfg.NTx86] and add the following two entries to the end of this section:
"ATI Mobility Radeon X1700" = ati2mtag_M66, PCI\VEN_1002&DEV_71D5&SUBSYS_12421043
"ATI Mobility Radeon X1700 " = ati2mtag_M66, PCI\VEN_1002&DEV_71D6&SUBSYS_12B21043
(6) Search for the "General installation section"
It consists of blocks of code.
Scroll down to the block with title [ati2mtag_M56].
Copy the whole block and past is again at the end of the current block.
In the block that you have pasted there are two places where M56 appear. First in the title and again within the block.
Rename the title as [ati2mtag_M66] and change the other M56 to M66.
(7) Search for section "Service Installation"
scroll again to the block [ati2mtag_M56.Services]. Copy the block and past it again. Rename the pasted block as [ati2mtag_M66.Services].
(8) Go to section "Software Installation" and search for the Block "[ati2mtag_M56.SoftwareSettings]" -> Copy it,Past it, Rename pasted block as [ati2mtag_M66.SoftwareSettings]
In this Block there is still one more M56 entry rename it also as M66.
(9) Next search for Block:
[ati2mtag_M56_SoftwareDeviceSettings] -> Copy it, Past it, Rename pasted block as [ati2mtag_M66_SoftwareDeviceSettings]
(10) Now search for the last Block:
[ati2mtag_M56.GeneralConfigData]-> Copy it, Past it, Rename pasted block as [ati2mtag_M66.GeneralConfigData]
Please make sure that each time you copy the complete Block otherwise the procedure would not work properly.
That was it!
(11) Uninstall the old driver.
(12) Go to folder "C:\ATI\SUPPORT\7-1-mobile_xp_dd_ccc_enu_40212"
Now install the Catalyst control center by pressing: issetup.exe
Hopefully, this procedure will work for you as it did for me.
