[flashrom] [PATCH] Board enable (EC sleep) for Acer Ferrari 3400

[Magnus Alm]

Tested flashing with the backup file:

sudo flashrom -w BACKUP.ROM
flashrom v0.9.1-r993 on Linux 2.6.32-19-generic (i686), built with
libpci 3.0.0, GCC 4.4.3
No coreboot table found.
========================================================================
WARNING! You seem to be running flashrom on a laptop.
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.
========================================================================
Found chipset "VIA VT8235", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Disabling flash write protection for board "Acer Ferrari 3400"... OK.
Calibrating delay loop... OK.
Found chip "SST SST39SF040" (512 KB, Parallel) at physical address 0xfff80000.

This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE
Please email a report to flashrom at flashrom.org if any of the above operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -rV,
-wV, -EV), and mention which mainboard or programmer you tested.
Thanks for your help!

Flash image seems to be a legacy BIOS. Disabling checks.
Writing flash chip... Erasing flash chip... SUCCESS.
Programming page: DONE!ss: 0x0007f000
COMPLETE.
Verifying flash... VERIFIED.

Looked good, so I shut down the computer and it came up as normal.

Well done Michael ;-)

How do I remove the unneeded stuff from the .WHP file?

When I tried to flash with it, it gave me: Error: Image size doesn't match
