Hi,
I already tried some time ago to flash my hp xw9300 mainboard bios but with no luck. Then I realized that I was using Ubuntu on a VirtualBox so it maybe could not access the mainborad chip...
I retried in these days using an Ubuntu live-cd, and I also read this old forum thread

where a guy tells to have succesfully written a Tyan original bios on the HP branded version of the same mainboard (the Tyan K8WE S2895) that is the HP XW9300 mainboard. (I didn't connect pins as he edit it wasn't necessary to do that but to enable the jumper of boot block)
Hi Federico,
it seems like different versions of the firmware engage different write protection mechanisms and your version requires either a small piece of code in flashrom to disable the write protection or the ugly hack of connection the respective pins to VDD. The problem is that deriving the right commands for the board is not straight forward and no one bothered to find them yet (it requires reverse engineering the firmware files).
