DRIVERS AND DUAL BOOT PROBLEM WITH SONY VAIO

Question

i AM WILLING TO PURCHASE A LAPTOP LIKE SONY-VAIO-VGN-CR36G/B. BUT THE PROBLEM IS THAT SONY DOES NOT PROVIDE ANY DISK AND DRIVERS WITH IT.
1-) MY MOST OF THE WORK IS RELATED WITH WIN-2003-SERVER IF GET FORMATED THE SYSTEM AND RUN WIN-2K THEN HOW CAN I ARRANGE DRIVERS
2-) CAN I CONFIGURE THE LAPTOP AS DUAL BOOT WHEN VISTA IS ALREADY THERE.
3-) IS SONY VAIO FACING THE PROBLEM OF LOOSE BATTERY.? I MEANT IF SONY VAIO LAPTOP GETS SHECKED THE POWER GOES OFF.
