Firmware info

The trick with the ver.req file works well on the A540.

Pressing SET and DISP button shows the following screen:

Canon PowerShot A540
P-ID:311B PAL

Firmware Ver GM1.00B
No error
Jan 31 2006 11:02:45

Pressing SET and DISP button again results in:

Canon PowerShot A540
P-ID:311B  PAL

Adj Ver.002.002

The vers.req file works, too.
Pressing SET and DISP button a third time results in:

Canon PowerShot A540
P-ID:311B  PAL

Adj Ver.002.002
Total Shoot  :xxxx
Open Shutter :0
Close Shutter:0

The number P-ID:331B is a hexadecimal code for the platform version id. Note that the platform ID is almost the same as the S3 IS model: 311B vs 311A. Platform codes for other models can be looked up under P-ID.
