The SX10 shows the advanced fw info page with ver.req, vers.req and also with both files, always.@orkok:
The Canon firmware info ("184.108.40.206") is shown when there's no ver.req or vers.req file on the card's root folder,
so i guess you're running Windows & you've got the typical Windows issue...
[..] (WIN XP) [..]Sure its vers.req and not vers.req.txt? Check in explorer in the menu "Tools" -> "Folder Options" -> "View" whether "Hide extensions for known file types" is set.
