Adding Wi-Fi to Epsilon BIOS

Epsilon BIOS 1.1

For modchip users, Djhg2000 from our forums offers two ways to enable and customize Wi-Fi on Epsilon BIOS: The hard way and the easy way. Yeah, you’re going to want the easy way first, wouldn’t you?

The easy (well, easier) way is to use his Epsilon BIOS Wi-Fi editor, downloadable from the link below. Instructions are included in the package (please read them!), but this will require the user – meaning you guys – to finalize the result with fixupdreg2.exe, which is NOT included in the package. And we’re not including it, for the obvious reasons. That last step is up to you.

On the other hand, there’s the hard way.

It requires the full article to display all the instructions.

On the other hand, there’s the hard way. It will require FileAssistant 0.4 installed on a Memory Stick Duo with at least 146,012KB free space remaining after the FA installation, and 1.50 firmware on the PSP. It will also require a bit of patience from the user – meaning you guys – as you go through each step (these steps come from Djhg’s post in the forums):

  1. Start your 1.50 PSP
  2. Add you WiFi connection in the XMB (note that all connections will be copied)
  3. Load up FA
  4. Press L to sycle the command menu and highlight “Disk”
  5. Press R to execute command
  6. Highlight “BIOS 1” and press O
  7. Highlight “Resistry” and press O
  8. Scroll down until “system.ireg” is highlighted
  9. Press [_] twice to highlight “system.ireg” and “system.dreg”
  10. Make sure it says “ms0:/” inside the upper right field
    • If it isn’t, press right and then go to “Disk” and execute, and then press left
  11. Cycle the command menu until “Copy” is highlighted
  12. Press R to execute
  13. Wait for the copy to finish and then shut it down
  14. Insert the MS Duo into your PSP with Epsilon BIOS
  15. Load up FA
  16. Press right to choose target folder
  17. Cycle the command menu to “Disk” and execute
  18. Note that the menu appears to the left this time
  19. Highlight “BIOS 1” and press O
  20. Highlight “Registry” and press O
  21. Now switch back to the source folder by pressing left
  22. Scroll down to “system.ireg” and press [_] twice to highlight the system files
  23. Cycle the command menu to “Copy” and execute
  24. Wait for the copy to finish and then reboot
  25. Test your connection in for example PVNC
