I finally created a batch to update them all..
Installation Method:
1. Copy all files in D:\win9x (where d is you cd-rom letter) to c:\updt (or whatever name you want)
2. Copy this file into that directory
3. Reboot and F8 -> Command Prompy Only
4. Run the file (u98stome.bat)
5. You are DONE !
I recommend you setup a clean 98se before going into this process..
Going through [Setup->Driver installation->Directx9.0c installation->Windows 98se Unofficial SP install->This process] works fine..
