A new port would be needed to support 101B. There is not a firmware dump yet, so porting cannot be started. Even if there was a dump, there is no developer with the camera, although if the differences are minor, a "blind" port isn't out of the question.

See http://chdk.wikia.com/wiki/Porting_the_CHDK for information on how to obtain the dump and http://chdk.wikia.com/wiki/Adding_support_of_a_new_camera for how to make a port once you have that.

You will not find a "downgrader" that will turn your 101B camera into the supported 100e version. The firmware dumps we use for porting are not suitable for re-flashing to the camera.
Don't forget what the H stands for.

I have made a dump of the IXUS 980 IS 1.01B firmware, it can be found here http://www.frogkick.dk/projects/photo/CANON_IXUS_980_IS_1.01B_PRIMARY_cam-firm.zip. It would be great if somebody with knowledge of the 1.00E firmware could check how different the two versions are.

I would very much like to be able to take underwater photos in RAW format :D

Yours!

Purchased a Powershot SD990 today in Toronto.

Firmware: 1-5.0.1.0

Is this yet another firmware version?

That's not the firmware version.  See

Please note! your camera's firmware version is NOT 1.0.0.0 or 1.0.1.0! It's a number that looks similar to this example: 1.01e. If you get a number like 1.0.1.0, then you did not do it properly and probably the ver.req or vers.req file in the root directory of the inserted SD-card is missing.

You are in luck then, that's the only version that is currently supported.

Hello,

I got two new ixus980 a few days ago which have FW 1.01B but there is some strange behaviour: when inserting any bootable SD card including a diskboot.bin file, card is locked this is what happens: camera boots up saying 'card locked' so it seems it ignores the diskboot.bin and also ignores booting it - I tried same SD card in a different ixus camera with the correct diskboot.bin file and it boots up, whereas on the ixus980 this does not happen (even with the flase diskboot.bin the camera shoud at least lock). Any ideas whats different here?

thanks
Werner

ok did some more tests - the ixus980 seems to ignore different diskboot.bin files from other cameras - using the diskboot.bin from ixus980 version 1.00e the camera crashes as expected.

greetings
Werner

Hello & welcome, Werner !

The firmware update loading mechanism always checks whether the Platform-ID is the correct one for this camera model.
Different firmware versions (and also different "brands" like Powershot/IXUS/IXY or PAL/NTSC cameras)  have the same P-ID.
A "foreign" CHDK (i.e. with the wrong P-ID) will be rejected with an error message or will be ignored...

So, since the 1.01B fw is not yet supported, it must be ported first...
