Can Windows 7 be installed on X05? I get ACPI incompatible BIOS and have updated to last known one. Please help!

The only issue i can see is if your your ram has not been updated since leaving the factory, you will notice from the tables W7 requires a min of 1GIG and your machine leaves the factory with 256mb(dependant on country possible) so check your ram. I run windows 7 on 2GB and its great, your machine will take 2GB. The Samsung X05 was released 2004 and the NVIDIA Geforce 4 should be fine. i would point out drivers and compatability but windows 7 so far is really good but driver support is crucial
hope this helps

Hay que entrar en la BIOS, entonces, dentro del men? advanced desactivamos el "speedstep".
Despues guarda los cambios pulsando F10 y reinicia. esta vez deber?a funcionar y dejarte terminar de formatear.

You must enter in the BIOS, then, you must go to the advanced menu and disable the "speedstep" option.
After doing that save the changes pressing F10 and restart the computer. It should work.
