Thanks for the info - though I did do just that, and each time I tried it, the image was missing. So I'm a bit stumped.

Can you confirm at what 'address' in gifExtractor the image should be located at?

When I initially run it on the vanilla modified navboot file and run the extract, I can see the ===BMW=== image - though at the address above where the image is, it is blank. So I click on the address where the image is located, do an 'exchange' and tick the Complex Gif and Ignore Filesize and load the image. Close down gifExtractor and re-run against the now modified navboot and the 'blank' location shows up but not the location where the splash was inserted.

Perhaps I am doing something wrong as I did have a right freak with the stuck disk this morning!! Any advice appreciated (but I have had no problems with other versions of navboot)!

Cheers,

Mark.
