+This is the universal (LinuxBIOS) flash utility.
-I am making this a general-purpose userland flash burner -- RGM
+Build Requirements
+------------------
-Earlier notes from Ollie:
+To build the flashrom utility you need to have the following packages
+installed on your Linux system:
-Here is some utilities for using/programming flash ROM on SiS 630/950 M/Bs
+* pciutils
+* pciutils-devel / pciutils-dev
+* zlib-devel / zlib1g-dev
- 1. flash_on, turnning on the flash writer enable for 630/950 M/Bs,
- you have to run this before load DoC drivers.
- 2. flash_rom, use your 630/950 M/Bs as a flash programmer for some
- flash parts. This utility is made as modular as possible. If
- you find your flash part is not supported, you can add a driver
- your own. Or sending me the data sheet.
+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.
+
+
+LinuxBIOS Table and Mainboard Identification
+--------------------------------------------
+
+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 AGAMI:ARUMA agami_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
+* GIGABYTE GA-M57SLI-S4 v2.0: use -m gigabyte:m57sli
+* GIGABYTE GA-M61P-S3: use -m gigabyte:m61p
+* MSI K8N Neo3: use -m msi:k8n-neo3
+* Acorp 6A815EPD: use -m acorp:6a815epd
+
+
+ROM Layout Support
+------------------
+
+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 agami_aruma.rom
+
+To update normal and fallback but leave the VGA BIOS alone, say:
+
+ flashrom -w -l rom.layout -i normal -i fallback agami_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
+--------------------
+
+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.
