Problems with Jetway Board and Winbond chip

[HaMa]

Hey there…

first of all: Thank you for that incredible flashrom tool.
But sadly: I can not write my BIOS chip on my Jetway Board.

I got a Jetway NC96FL Mainboard with a Winbond W25Q80BV BIOS Chip, Intel 
NM10 Chipset and running Ubuntu 10.10.
Flashrom detects the chip and the chipset well, but can not disable 
block protection. So it is not possible to write.

I also tried to flash the chip with the Serprog/Arduino-Flasher on an 
Arduino Uno and it works. (But I want to burn it with my Jetway Board.)
Then I tried to write it in my Jetway Board with manual raising the 
/WP-Pin of the Winbond Chip to VCC and it works too.
So is it something (GPIO) to raise the /WP-Pin in the chipset?
Can somebody help me?

I attached the logs from:
$ flashrom -p internal -V (flash.log)
$ lspci -nnvvxxx (lspci.log)
$ superiotool -deV (superio.log)

Thanks a lot,

Hans-Martin
