| .SH DESCRIPTION |
| .B flashrom |
| is a universal flash programming utility for DIP, PLCC, or SPI flash ROM |
| chips. It can be used to flash BIOS/coreboot/firmware images, for example. |
| .sp |
| (see |
| .B http://coreboot.org |
| for details on coreboot) |
| .SH OPTIONS |
| If no file is specified, then all that happens |
| is that flash info is dumped and the flash chip is set to writable. |
| .TP |
| .B "\-r, \-\-read" |
| Read flash ROM contents and save them into the given file. |
| .TP |
| .B "\-w, \-\-write" |
| Write file into flash ROM (default when file is specified). |
| .TP |
| .B "\-v, \-\-verify" |
| Verify the flash ROM contents against the given file. |
| .TP |
| .B "\-E, \-\-erase" |
| Erase the flash ROM device. |
| .TP |
| .B "\-V, \-\-verbose" |
| More verbose output. |
| .TP |
| .B "\-c, \-\-chip" <chipname> |
| Probe only for specified flash ROM chip. |
| .TP |
| .B "\-s, \-\-estart" <addr> |
| Exclude start position (obsolete). |
| .TP |
| .B "\-e, \-\-eend" <addr> |
| Exclude end postion (obsolete). |
| .TP |
| .B "\-m, \-\-mainboard" <[vendor:]part> |
| Override mainboard settings. This option is needed for some mainboards, |
| see the |
| .B "flashrom \-\-list\-supported" |
| output for a list. The vendor is not required when the board name is unique. |
| .TP |
| .B "\-f, \-\-force" |
| Force write without checking whether the ROM image file is really meant |
| to be used on this board. |
| .sp |
| Note: This check only works while coreboot is running, and only for those |
| boards where the coreboot code supports it. |
| .TP |
| .B "\-l, \-\-layout" <layout.file> |
| Read ROM layout from file. |
| .TP |
| .B "\-i, \-\-image" <name> |
| Only flash image |
| .B <name> |
| from flash layout. |
| .TP |
| .B "\-L, \-\-list\-supported" |
| List the ROM chips, chipsets, and mainboards supported by flashrom. |
| The list of mainboards consists of those boards which need a special |
| ROM write-enable function for flashrom to work. |
| .sp |
| There are many other boards which will work out of the box, without such |
| special support in flashrom. Some of the known-good/known-bad and tested ones |
| are listed at |
| .BR http://coreboot.org/Flashrom#Supported_mainboards , |
| but the list is not exhaustive, of course. |
| .TP |
| .B "\-h, \-\-help" |
| Show a help text and exit. |
| .TP |
| .B "\-R, \-\-version" |
| Show version information and exit. |
