According to this article about Windows Vista Requirements:
Other requirements included a SATA or 7200 rpm EIDE hard drive. For Vista on notebooks, Microsoft recommended the Acer Ferrari 3400, the Acer Ferrari 4000, the HP Pavillion zd8230, the IBM Thinkpad T43 and the Toshiba Tecra M4.
Sweet! If IBM/Lenovo will adjust their BIOS so there’s no more error when using a standard Hitachi or Seagate 7200 RPM drive, this sucker will be ready to go.
Very cool, this is a rather decent system. I like hearing that it’s anticipated to work well with Vista. That means I can keep it around for a while, and still be modern.
