This is the Windows port of the universal (LinuxBIOS) flash utility. It's named winflashrom. This code has not been merged into the LinuxBIOS repository. Therefore, it's available publicly only from Google Project hosting for a while. There are still some minor issues that prevent us to merge it into the LinuxBIOS repository. Anyway, you might want to watch LinuxBIOS mailing list (http:https://www.linuxbios.org/mailman/listinfo/linuxbios) for further updates on Winflashrom. Once a stable release of Winflashrom is available. The code in Google Project hosting will be updated as well.

To build the winflashrom utility you need to have the following packages installed on your Windows system:

• MinGW
• MSys
• Windows XP DDK or Windows Driver Kit (WDK). This tool is optional because the package comes with a precompiled driver. However, if you want to make changes to the driver source code, you will need one of them.
• DbgView (optional). You can use this tool for remote debugging if you want to try some changes to the driver code. DbgView is available from Sysinternals as a freeware.

• Building the application. To build the application, "cd" to the source code root directory of the source code from within MSys (or other compatible shell that you might use) and invoke "make".

• Building the driver. To build the driver, run the Windows XP DKK or WDK shell (The WinXP Free Build environment or the WinXP Checked Build environment). Then, "cd" to the directory named "driver" in the root directory of the source code and invoke "build" from there. If you would like to have debugging message, use the "The WinXP checked build environment" of the Windows XP DDK or WDK shell.

• Remote debugging the driver. To do a remote debugging, first run the DbgView client in the test machine by invoking the following command in DbgView installation directory: DbgView.exe /c /t Then, connect to the test machine from the remote machine by running DbgView.exe. In the remote DbgView window, activate the Capture|Capture Kernel option, Capture|Pass-Through option, and Capture|Capture Events option and Disable the Capture|Capture Wind32 option as it will clutter the output with unnecessary messages. Now, you can monitor the debug messages from the test machine.

usage:

./flashrom [-rwvEVfh] [-c chipname] [-s exclude_start]
[-e exclude_end] [-m vendor:part] [-l file.layout] [-i imagename] [file]
-r | --read:                    read flash and save into file
-w | --write:                   write file into flash (default when
                                file is specified)
-v | --verify:                  verify flash against file
-E | --erase:                   erase flash device
-V | --verbose:                 more verbose output
-c | --chip <chipname>:         probe only for specified flash chip
-s | --estart <addr>:           exclude start position
-e | --eend <addr>:             exclude end postion
-m | --mainboard <vendor:part>: override mainboard settings
-f | --force:                   force write without checking image
-l | --layout <file.layout>:    read rom layout from file
-i | --image <name>:            only flash image name from flash layout

If no file is specified, then all that happens is that flash info is dumped and the flash chip is set to writable.

Flashrom reads the LinuxBIOS table to determine the current mainboard. (Parse DMI as well in future?) If no LinuxBIOS table could be read or if you want to override these values, you can specify -m, e.g.:

flashrom -w --mainboard ISLAND:ARUMA island_aruma.rom

The following boards require the specification of the board name, if no LinuxBIOS table is found:

• IWILL DK8-HTX: use -m iwill:dk8_htx
• Agami Aruma: use -m AGAMI:ARUMA
• ASUS P5A: use -m asus:p5a
• IBM x3455: use -m ibm:x3455
• EPoX EP-BX3: use -m epox:ep-bx3

Flashrom supports ROM layouts. This allows to flash certain parts of the flash chip only. A ROM layout file looks like follows:

00000000:00008fff gfxrom
00009000:0003ffff normal
00040000:0007ffff fallback

i.e.:

startaddr:endaddr name

all addresses are offsets within the file, not absolute addresses!

If you only want to update the normal image in a ROM you can say:

 flashrom -w --layout rom.layout --image normal island_aruma.rom

To update normal and fallback but leave the VGA BIOS alone, say:

 flashrom -w -l rom.layout -i normal -i fallback island_aruma.rom

Currently overlapping sections are not supported.

ROM layouts should replace the -s and -e option since they are more flexible and they should lead to a ROM update file format with the ROM layout and the ROM image in one file (cpio, zip or something?)

DISK on Chip support is currently disabled since it is considered unstable. Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.

This code has been successfully tested on Pentium 4 (single core) system with ICH5 chipset and Winbond W39V040FA flash chip.

The driver architecture is still messy at this point. However, I'm working on to improve it right now and it should come with better code very soon.
