Strange. From the times listed, I was editing it while you were posting. Never saw a board do that before.

BTW You should also be able to format without DOS: 'My Computer' -> right-click card -> choose format
        Just make sure it uses FAT not FAT32 (there should be an option for that)

I've tried it that way also. Make bootable stays grayed out though, and that's the only thing I really need to do.

OK, in that case: follow fe50's recommendation and download HxD here:

(free download) http://mh-nexus.de/en/downloads.php?product=HxD

i also did, so let me know when you're ready ...

edit: just tested it (verified with CardTricks) and it works. In the program, you first need to
        goto menu Extras -> Options -> Security (on tab General) -> uncheck "Open disk as readonly by default"
        Click OK.
        then, goto menu Extras -> Open disk and select your card's drive letter under "Logical disks"
        (BTW, always format cards with CANON_DC as drive label (like your cam does)  that makes it easier to recognize
          them - this program also shows the drive label)
        Click OK to dismiss the warning and your card will be opened in the editor.
        It's the rightmost column that we're interested in - this shows the ASCII representation of the card.
        In the first line of this column you should see MSDOS5.0, in the 4th there should be FAT16. Yes ?
        Then put the cursor on the 1st character of the 5th line and type (capitals !) BOOTDISK
        Then goto menu File -> Save , OK the warnings and close the program. Done.

Okay, I've downloaded the hex editor, have placed the build on an old 256 card to play around with, (which was fully formatted via right click in My Computer), and here's what I see, just so you'll know where I'm at:




I might be busy for a while tonight, so might not get back to you quickly.

Joe - still can't see whatever you're including - but check my previous post, I edited it with a detailed guide.

By George, that was easy enough. It works!     :D

To recap, for anyone who'll read this later:

I fully formatted my card by right clicking on it in My Computer, making sure that CANON_DC was the volume label (it always is if you used the card in the camera first, no doubt you'll have to label a new card), used Card Tricks to get my camera build onto the card (which I might be able to do manually - will check later), then used the hex editor to type BOOTDISK on the 5th line of the header.

Now I have something to understand by comparison. This is sorta like editing the header in a .jpg.

Thank you!

@Joe

Nice ! Just remember every time you do this to check if it says FAT16 on line 4 ...
(i'm not sure from which size camera's start formatting FAT32, but they definitely
  do for 4 Gb and up)

cheers,

wim

yes, it's just an unzip operation

exactly, you can also do that with this program.

I just now got another card to work, a 1 gig. Tried it on a 4 gig card, but it didn't work, but that's okay since it did work when I set it up on my friends machine. (Don't understand much of it, of course, but I noticed the header was a little different on the 4 gig).

All in all, I can now make do with anything less than a 4 gig, until I can get to an XP machine. Wim, thanks for your help!

Oops.  fe50, thanks to you as well.

The problem is the Win98 format command: there's no /FS: switch since Win98 can only use FAT.

Up to 2GB format uses FAT16, with 4GB automatically FAT32 is used - that's why CT disables the bootable button.
It's also the same with in-camera formatting...

So the card should be formatted on a Windows XP machine with FAT16 (either with Cardtricks or in a CMD windows with the /fs:FAT parameter), on Linux it should also be possible.
Maybe there's another format tool that can do it...

I wonder how a 4 gig standard card would work with what you guys have taught me, (not an SDHC type, which both of mine are). Seems there aren't that many of the standard ones around. Perhaps nobody's tried?
