The model P1500 touchscreen can accomodate WXP,and has support in the bios for booting with a usb optical drive.I don't believe your model does,it's too old,but I see that there is a pcmcia cd rom for that model.

Specs:For B110

* 3.2GB hard drive (larger on later models)

* IR port
* 2 USB ports
* PS/2 mouse + keyboard port (single port, double head cable)
