I'm sure the CPU and memory will work fine with Haiku, the main issue would be the motherboard ACPI interface, the hard drive controller and video. As far as I can tell most L520 models just use the built-in Intel Extreme HD video. Haiku does not yet support that with a native driver, though I think it should at least work in VESA mode. Once I get my new hardware set up I may start my Haiku video-driver writing career by writing a driver for the Extreme HD, since Intel has pretty extensive PDF documentation for it on http://intellinuxgraphics.org. Apparently it is different enough from the normal Intel Extreme that it needs a new driver (similar to Radeon and Radeon HD.) Can you get to the boot menu screen by pressing space before the boot loader? If you turn on the screen debug output you should have a better idea of where things fail. Otherwise I'll probably be trying to boot Haiku on my new hardware within the next week. Of course getting a desktop machine booting may be easier than a laptop. In the worse case I can add a supported video card and turn off the embedded Extreme HD. -- Regards, Ryan My L520 uses the built-in Intel Extreme HD videocard. The notebook boots from CD and I can´t see the bootscreen. So pressing space didn´t work or my fingers are to slow ;).
