coreboot lenovo x230

[Mario Goljak]

I've been following coreboots official guide
http://www.coreboot.org/Board:lenovo/x230 but I'm unable to read bios chip
content with the buspirate and flashrom. I've connected it according to
this datasheet
http://www.macronix.com/Lists/DataSheet/Attachments/1740/MX25L3206E,%203V,%2...
but I'm not exactly sure how to connect 3.3V power lines from another
computer. can somebody please give me some guidelines. thanks in advance.
