As each card matching the devce:vendor ID is claimed by your driver, simply call the firmware loader with a corresponding file name. How you determine the file name is up to you - This could be from a default list, or an array passed at load time. An alternative would be:... On Wednesday 02 May 2007 18:00, Peter C.

Useful - Would there be sufficient space for 16 or 32 characters ? Presumably, a trivial user space utility would be needed to "burn in" any file names..

And as always, there is a multitude of wrong ways of doing something. This bfload is just one of them. Presumably the "what" and "where" also extends to "when" so a user can dump a new firmware blob on a live system.. Yet another example of user space binary that requires root permissions, ignores proven, stable libraries/methods in favour of NIH programming. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
