In PLAY mode (without ver.req) press FUNCSET and DISP simultaneously:
Firmware Ver. 1.0.0.0 [ OK ]
In PLAY mode (empty file named ver.req must be previously created on card root) press FUNCSET and DISP simultaneously:
Canon Powershot SX100 IS P-ID:315E PAL D Firmware Ver GM1.00B NoError 31 2007 19:07:47
subsequent press of DISP (while still holding FUNCSET) reveals:

On another camera, the following results were seen:

If you use vers.req instead of ver.req at the last screen is the following instead of the previous:

In my firmware 1.00B the "DRYOS version 2.3, release #0023" can be found in the ROM area.
Running CHDK[]
After CHDK is installed on the SD card, turn camera on by pressing the "Play" button (i.e. switch it to play mode). After that, go to menu and enter "Firmware update" menu item.
In case the card is made bootable and is locked to read-only mode, CHDK is loaded automagically on device power-on.
For Developers[]
LED memory addresses[]
To run the blinker you must have "bootable" SD card with "diskboot.bin"
#define LED_AF 0xc02200C0 // AutoFocus #define LED_BLUE 0xc02200C4 // next to the printer #define LED_RED 0xc02200C8 // next to the play button, rather orange #define LED_GRN 0xc02200CF // in the same position as above, but in green #define LED_PWR 0xc02200D0 // green power on top of the camera
Dumping the firmware[]
An almost ready made dumping version (camera, PC), is available you can find here: blinker_sx100.zip
It could be very good to know if all the 1.00B versions are the same and what is the difference among versions.
Firmware dumps[]
- Firmware dumps of the 1.00B and 1.00C firmwares are available from the drop.io chdkdumps backup archive:
