ThinkPad X220 Expresscard Serial Port

[Knovats]

I recently bought a ThinkPad X220 with an expresscard slot because I need a direct serial port (NO USB adapters please). I cannot run my software in Win7 and I cannot access my serial port expresscard in XP virtual machine. I tried to install XP as dualboot but the whole system crashes immediately after installing drivers and attempting install startup. I need to either resolve installing the dualboot system or configuring the expresscard in virtual machine. I tried both the Windows and the Oracle virtual machines. XP works fine but I cannot set up a com port on the serial expresscard. Any solutions?? Is it possible to purchase a WinXP install disc with Lenovo ThinkPad/Tablet drivers?
