Could someone explain that a little more in detail?

I built the normal image, but it didn't boot like expected. It seems that the 
ide drives get initialised, but i don't get any response on my monitor.
I also tried to compile a LAB image, where i get as response on the monitor 
just a blinking "_". On building the LAB image, i used the normal buildrom 
and just modified two ROM size parameters.
