Firmware update cdrw 52-24-52

Hello,

I have brought a Btc cdrw 52-24-52 model CDWRITERIDE 5224 that I have
inserted in a my rack usb 2.0 for using with my notebook.
I want update the firmware.
When I go to:

http://www.btceurope.nl/english/3-1-3driver_download.htm

I see two firmware for model:

BCE 5224IM internal ide

and

BCE 5224UI external usb 2.0.

What is the right firmware that I must use?

The unit is the same, so I suppose the only difference is in the flasher itself. One is designed for IDE flashing, and the other for flashing through the USB port.

They actually link to the same file :wink:
