"Bocked"? Is that a word?

The key combination you mention is for resetting parameter RAM or PRAM. Nothing really to do with passwords.

At what stage is it asking for a password?

The word is "blocked". Sorry

When I press and hold option key at startup, the iMac ask me for a passwd before showing me the list of disks

I have never set this password so i want to know how to remove it. I red on a tutorial that in this case one only need to remove one stick memory and hold command-option-p-r. I tried that on another imac it worked but it doesn't work anymore on mine
