I have a 4GB SDHC card that i'm trying to use to boot an a650is. i'm running os x 10.5.6.
I can successfully format the card as FAT16. An a570is can boot from this card. however, the "make bootable" function in chdk doesn't allow it to autoboot with the card.
i suspect that the problem is that i don't understand quite where to put the boot file name. i have gotten this to work with smaller cards.
the info from hexedit before and after modification is included in the text file. seems like the forum doesn't like previewing that info.
any suggestions?
