How can I modify a Windows part of firmware?

[smart2003]

I need to replace some files in Windows of my magician to make my device read 2 Gb 150x SD cards. How can I modify the nc.nbf file of a firmware?

This isn't sooo easy as far as i know...
Do you know what you want to do? What files want you to change?

Windows doesn't allow me to replace the drivers of a SD card. I want to replace these files with the files from the previous version of Windows.

The only way I know of would be to edit the ROM files in Hex using a hex editor. This would be very difficult, as I don't know of a reference that would tell you where in the ROM file your particular file is found. But it could be done. If you found the file location you might could remove the file, then paste in your file - all in hex, of course.

Instructions for dumping your ROM can be found with a search of the "upgrading your Magician" board.
