| 10 | To build the flashrom utility you need to have the following packages |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 11 | installed on your Linux system: |
Stefan Reinauer | 06b2c4d | 2005-12-01 10:51:08 +0000 | [diff] [blame] | 12 | |
| 13 | * pciutils |
Uwe Hermann | 83f0db2 | 2006-12-20 14:53:22 +0000 | [diff] [blame] | 14 | * pciutils-devel / pciutils-dev |

| 22 | [-e exclude_end] [-m vendor:part] [-l file.layout] [-i imagename] [file] |
| 23 | -r | --read: read flash and save into file |
| 24 | -w | --write: write file into flash (default when |
| 25 | file is specified) |

Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 32 | -m | --mainboard <vendor:part>: override mainboard settings |

Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 37 | If no file is specified, then all that happens |
| 38 | is that flash info is dumped and the flash chip is set to writable. |

Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 44 | Flashrom reads the LinuxBIOS table to determine the current mainboard. |
Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 45 | (Parse DMI as well in future?) If no LinuxBIOS table could be read |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 46 | or if you want to override these values, you can specify -m, e.g.: |

Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 52 | ------------------ |
| 53 | |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 54 | Flashrom supports ROM layouts. This allows to flash certain parts of |
| 55 | the flash chip only. A ROM layout file looks like follows: |
Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 56 | |
| 57 | 00000000:00008fff gfxrom |
| 58 | 00009000:0003ffff normal |
| 59 | 00040000:0007ffff fallback |
| 60 | |
| 61 | i.e.: |
| 62 | startaddr:endaddr name |
| 63 | |
| 64 | all addresses are offsets within the file, not absolute addresses! |
| 65 | |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 66 | If you only want to update the normal image in a ROM you can say: |
Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 67 | |
| 68 | flashrom -w --layout rom.layout --image normal island_aruma.rom |
| 69 | |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 70 | To update normal and fallback but leave the VGA BIOS alone, say: |
Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 71 | |
| 72 | flashrom -w -l rom.layout -i normal -i fallback island_aruma.rom |
| 73 | |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 74 | Currently overlapping sections are not supported. |
Ollie Lho | 184a404 | 2005-11-26 21:55:36 +0000 | [diff] [blame] | 75 | |
Uwe Hermann | 2dc5f42 | 2006-11-20 20:32:35 +0000 | [diff] [blame] | 76 | ROM layouts should replace the -s and -e option since they are more |
| 77 | flexible and they should lead to a ROM update file format with the |
| 78 | ROM layout and the ROM image in one file (cpio, zip or something?) |

| 82 | ----------- |

| 84 | DISK on Chip support is currently disabled since it is considered unstable. |
Stefan Reinauer | cbc55d0 | 2006-08-25 19:21:42 +0000 | [diff] [blame] | 85 | Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS. |
