Chdk version for manual (via "Firmware update" option) load.

For 1.00C and probably 1.00B

Converted from unencoded xianofeng's diskboot using fi2 encoder and 31C3 P-ID (for A1100 IS)

Please test and see how it works.

It does not work with Firmware 1.00C.
No flashing blue light. indicating bootup.
A1100 reports that SD card is locked.

xiaofeng's diskbboot May 11, 2010 build does work (within limits)
using the review button to power up.

Xiaofeng:

Good news for the A1100 porting. Some parts of the scripting work.
The following interval script works using CHDK 0.9.9 Date Jun 23 2010  FW 100C

rem Author - Keoeeit
rem a1100 LCD screen OFF  hha 20100721
@title a1100 Intervalometer
@param a Delay 1st Shot (Mins)
@default a 0
@param b Delay 1st Shot (Secs)
@default b 0
@param c Number of Shots (0=inf)
@default c 0
@param d Interval (Minutes)
@default d 0
@param e Interval (Seconds)
@default e 0
n=0
t=d*60000+e*1000
if c<1 then let c=0
if t<100 then let t=100
do
  click "display"
  get_prop 105 s
until (s=2)
g=(a*60)+b
if g<=0 then goto "interval"
for m=1 to g
 sleep 930
next m
:interval
  n=n+1
  if c=0 then print "Shot", n else print "Shot", n, "of", c
  shoot
  if n=c then end
  sleep t
  goto "interval"


With zero delays and with 1/50 sec exposure (selected by the A1100 in P-mode) and C=5,
the a1100 produces shots at  1.4, 3.7, 5.9, 8.2, and 10.6 seconds after pressing the shutter button,
with the images saved as normal quality 5 Mp jpeg.
The 2.3 seconds mean separation between shots is the time save one image.
get_prop 105 turns the LCD OFF and decreases the mean battery current from 560 mA to 420 mA.
This is less than I expected, probably because the software timing loop keeps the CPU clock speed high.
The red and green LED flashes to show activity.
Curiously the "Shot n " etc messages still flashes up for an instant.
With c=0 and 15 sec exposure in SCN=Night Mode and dark-frame subtract, the a1100 shot 102 pictures of the night sky
in one hour, when I stopped the sequence.

Some other features of CHDK are not working, maybe because the a1100 has no Manual mode,
or because some variables or memory locations have been switched around.

We all know that the CHDK software updates the CCHDK.cfg file in the CHDK directory on the SD card just before the camera is powered OFF. This file gets occasionally corrupted, presumably when exploring incorrectly implemented CHDK menu options or function calls. In that case, when turning the power ON using the review button, the blue light blinks (=success), then the camera turns the LCD and everything else OFF and responds to nothing. I never needed to do this on my a530, so I presume this is an indication that the pre-beta release of diskboot ( CHDK 0.9.9 Date Jun 23 2010  FW 100C) is not stable.

It seems like I was trying different auto-iso settings or shutter speed over-ride. Has anybody else noticed this and was able to correlate this with any specific action?

The solution is to replace the CCHDK.cfg file with the last good version. Then all returns to normal. If no computer is near, change the SD card to "unlock".

Actually, CHDK does not know when the camera is being turned off. AFAIK The config is written when you leave the CHDK menu, or leave ALT mode, IFF it has changed .
Don't forget what the H stands for.

Can someone help me? I'm new with CHDK, and I'm trying to install it on my A1100 IS. But I don't have firmware update option in display mode with sd card locked (or not). I copied on card ps.fi2 file (and later also DISKBOOT.BIN). What am I doing wrong?

To see the firm update option, you usually must start your camera with the play button, not the power button.

Usually this means you are using the wrong build for your firmware version.
