From the readme file I have:-
1. Download Sony CD Extreme [alternate location]
http://www.webtree.ca/newlife/user/CDExtreme.zip
2. Unzip that file and install Sony CD Extreme
3. Download this update for the Sony CD Extreme software.
http://sony.storagesupport.com/cdrw/downloads/SonyCDExtremeUpdate.zip
4. Unzip that file and update the software.
5. Download this Prassi engine update (for more burner compatibility)
ftp://eval.veritas.com/downloads/pro/exe/PxEngineUpdate327.exe
6. Run that EXE to install the newer Prassi engine.
7. The manual can be found here in PDF format.

8. Run the Sony CD Extreme software
9. Click on 'go to full application'. Select your burner drive from
the column on the left.
10. File --> New Job --> Data disc
11. Enter your Volume Label beside 'Volume Label'
12. Right-click in the middle of your screen and choose 'Add Folder'.
Pick the folder you want to burn.
13. Right-click again in the middle of your screen and choose
'Recording Options'. Beside 'File System Type', choose ISO Level 2
(212 characters). Click OK.
14. One note, under the 'Speed' dropdown box, pick the speed you want
to burn at instead of choosing 'max'. For some reason on 'max' it
would only burn at 4X with my 8X burner, so I had to choose 8X
manually.
15. Choose 'record' from the pull down menu. Click the red record
button.
And there you have it.
