S5IS

The Canon PowerShot S5 IS is a an 8.0 megapixel bridge digital camera. It uses DryOS instead of vxWorks. As of 2008-04-07, CHDK works on the S5IS (1.01b).

Notes:

• The S5 lacks an intervalometer, even though the S1, S2, and S3 have one. The closest thing it has natively is a "custom timer" -- a timer that will take multiple photos. Use a CHDK intervalometer script to add this feature.
• RAW samples have been submitted to rawsamples.ch and are also available for direct download [1]. UFRaw does not support S5 yet, but dcraw (upon which it is based) apparently does.
• Use DNG4PS to convert the raw files to .dng format, which can then be read by GIMP+UFRaw or by sufficiently recent versions of Adobe Photoshop.

Installation

S5IS CHDK does not have PS.FIR, so you'll have to follow these steps:

• Make sure your card is 4 GB or less. Bigger cards require FAT 32, which requires some extra-special steps.
• Format your card as FAT 16.
• Make the card bootable using the instructions for your operating system.
• Create the MISC and DCIM folders.
• Drop the latest DISKBOOT.bin onto the card.
• Lock the card using its switch.
• Insert the card into your camera.
• Turn on your camera.

Note: CHDK will already be loaded after turning on your camera, there is no need for using the "Firmware Update" menu entry to load CHDK (also because that entry will not be there because there is no PS.FIR / PS.FI2).

Developer notes

Firmware versions

As in the A610 case, the ver.req file works as well in this model.

Presumably, the "NT" in the upper block refers to "NTSC", because a camera bought in Europe (see below) had "PAL" in the same location.

1.01A

Upper block:

Canon PowerShot S5 IS
P-ID:3148  NT D

Lower block:

Firmware Ver GM1.01A
No error
May 29 2007    18:17:20

Pressing DISP twice more (still holding SET) returns this additional block:

Adj Ver.007.000
IS Firm Ver.  3.00
IS Param Ver.  3.00

A copy of the 1.01A firmware dump (from 0xff810000) for the camera listed above (dumped via blinking the AF led) is available here.

1.01B

Another version has this lower block:

Firmware Ver GM1.01B
No error
Jun 14 2007    16:12:20

The upper block and additional text are the same as with 1.01A, though. (Timestamp changes, of course.)

A copy of the 1.01B firmware dump is available here (md5: 63f211fe670b185e48b3062aefd789ca).

Another camera with 1.01B (American-bought) returned a timestamp of Jun 14 2007 20:11:19. Note that this is the same timestamp as the European one below.

European 1.01B

Another version bought at Amazon in Germany (Made in Japan):
