During installation on real hardware with either the i586 or x86-64 iso images, I get a delay of at least 5 minutes, when the message "looking at packages already installed" (or something to that effect) is displayed. According to the log, the last thing run was running: monitor-edid -v --perl I'll attach the output from that command on an installed Mageia 2 system. I didn't notice such a delay with the dual-cd.
Created attachment 2912 [details] Output of monitor-edid -v --perl
