Finally, I managed to modify the Omega driver to get it working on 9800SE with the help of recent
forum :
http://www.driverheaven.net/showthre...&postid=197125
1 ) What i did is install the omega driver v2.4.78 for Win 2k/XP, while installation it will pop up the BIG RED ATI install screen, and lisence. And it show error on *.inf etc... Ignore the ERROR.
2 ) Browse to C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF
Select either one (depends on what refresh rate user select later in the installation) :
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\75Hz
Or
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\85Hz
Or
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\100Hz
3 ) Find the directory mentioned above and keep browsing till you find two INF file called
"C2_RAD_OMEGA.inf" and "CX_RAD_OMEGA.inf"
Open these INF files for EDITING. Notepad or whatever.
Find the [ATI.Mfg] section.
Should look like this, < a REAL CATALYST inf is much longer. I have removed a bunch of lines>
++++++++++++++++++++++++++
[ATI.Mfg]
"RADEON 9700 PRO (Omega 2.4.78) " = ati2mtag_R300, PCI\VEN_1002&DEV_4E44
"RADEON 9700 PRO - Secondary (Omega 2.4.78) " = ati2mtag_R300, PCI\VEN_1002&DEV_4E64
"RADEON 9800 (Omega 2.4.78) " = ati2mtag_R350, PCI\VEN_1002&DEV_4E49
"RADEON 9800 - Secondary (Omega 2.4.78) " = ati2mtag_R350, PCI\VEN_1002&DEV_4E69
"RADEON 9800 PRO (Omega 2.4.78) " = ati2mtag_R350, PCI\VEN_1002&DEV_4E48
"RADEON 9800 PRO - Secondary (Omega 2.4.78) " = ati2mtag_R350, PCI\VEN_1002&DEV_4E68
"RADEON 9800 SE (Omega 2.4.78)" = ati2mtag_R350, PCI\VEN_1002&DEV_4148
"RADEON 9800 SE - Secondary (Omega 2.4.78)" = ati2mtag_R350, PCI\VEN_1002&DEV_4168
++++++++++++++++++++++++++
You must ADD these lines to the INF file already added in the above example. (note the IDs 4148/4168)
"RADEON 9800 SE (Omega 2.4.78)" = ati2mtag_R350, PCI\VEN_1002&DEV_4148
"RADEON 9800 SE - Secondary (Omega 2.4.78)" = ati2mtag_R350, PCI\VEN_1002&DEV_4168
Then you save the INF file with the new IDs.
Finally you install the driver by control panel -> Update display Driver, and you must browse to the directory ( eg.C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\85Hz )
**note: the 75Hz or \85Hz or \100Hz it depends on the update driver that user going to browse**
The key points to remember are,
1- must have driver unpacked on Hard Disk so you can edit the INF file.
2- Editing the inf will invalidate digital signing, so the driver will show as not certified.
4 ) After that go to control panal, go to Device Manager, update the display adapter on the Radeon Driver.
5 ) Update the particular driver, click install from a specific location , browse to :
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\75Hz
or
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\85Hz
or
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF\100Hz
6 ) Wait for it to install, while installing half way it require a driver, browse to:
C:\Program Files\Radeon Omega Drivers v2.4.78\2KXP_INF
Reboot!!! DONE!!! Now we got the latest 9800SE driver !!!
