flashrom v0.9.4-r1457 on Linux 3.1.10-1.16-desktop (x86_64), built with libpci 3.1.7, GCC 4.6.2, little endian
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
========================================================================
WARNING! You may be running flashrom on an unsupported laptop. We could
not detect this for sure because your vendor has not setup the SMBIOS
tables correctly. You can enforce execution by adding
'-p internal:laptop=this_is_not_a_laptop' to the command line, but
please read the following warning if you are not sure.

Laptops, notebooks and netbooks are difficult to support and we
recommend to use the vendor flashing utility. The embedded controller
(EC) in these machines often interacts badly with flashing.
See http://www.flashrom.org/Laptops for details.

If flash is shared with the EC, erase is guaranteed to brick your laptop
and write may brick your laptop.
Read and probe may irritate your EC and cause fan failure, backlight
failure and sudden poweroff.
You have been warned.
========================================================================
Proceeding anyway because user forced us to.
Found chipset "Intel ICH7/ICH7R". Enabling flash write... OK.
This chipset supports the following protocols: FWH.
Found Winbond flash chip "W39V080FA" (1024 kB, FWH) at physical address 0xfff00000.
Flash image seems to be a legacy BIOS. Disabling coreboot-related checks.
Reading old flash chip contents... done.
Erasing and writing flash chip...  writing sector at 0x7fd89861f600 failed!
Reading current flash chip contents... done. ERASE FAILED at 0x00048aa0! Expected=0xff, Read=0x60, failed byte count from 0x00000000-0x000fffff: 0xa85c8
ERASE FAILED!
FAILED!
Uh oh. Erase/write failed. Checking if anything changed.
Good. It seems nothing was changed.
Writing to the flash chip apparently didn't do anything.
This means we have to add special support for your board, programmer or flash chip.
Please report this on IRC at irc.freenode.net (channel #flashrom) or
mail flashrom@flashrom.org!
