Hi all,@raingrove: Thanks for a great guidance.Let me make some comments.4. insert CF, and then run firmware update again using testfir.fir the screen will go blank. wait 5 minutes, turn off, take battery out and back in.The testfir.fir make changes to 400d's boot flags immediately, so count down from 10 after testfir.fir blank your display screen. No need to wait 5 minutes.9. ......ISO levels 16/32/40/50 can also be enabled if you go to menu and turn "shoot without CF" ON, but not sure if they really work (i see no difference.)I think iso 16/32/40/50 are same as iso 160/132/140/150. Please test and post your comments so i can decide to keep them available or not10. .... to go back to "evaluative metering", you have to select other metering modes first, and then back to "evaluative metering", because the camera thinks you are at "evaluative" although you are at "spot metering".I will correct it soon and upload .bin file and source code too--------FYI-------------Dont have much time so no big Progress. Realy got stuck finding how to make and display a custom dialog. Not success to understand Canon's CreateDialogBox function (in firmware). It is very complicated. I dont know much about VXwork and Camera hardware. Still google for some documents. so inform you some ideas- Found out that there are alot focus point combinations others than Canon defaults such as cross; all points at top, at bottom, at left, at right; center point and 4 nearest points ... i'm trying to make it work.- Not sure if it can be enable focus confirmation for manual lens or not. if yes, you dont have to spend too much money for AF confirm mount (i have some M42 lens ).- Can we partition CF card to protect boot loader and the bin file from format or erase.- 60, 70, 80, 90, 100 second etc exposures would be useful, dont have a remote and holding shutter for bulb sucks (as requested by nicholas-c)
