.B flashrom \fR[\fB\-rwvEVfhR\fR] [\fB\-c\fR chipname] [\fB\-s\fR exclude_start] [\fB\-e\fR exclude_end]
[\fB-m\fR vendor:part] [\fB-l\fR file.layout] [\fB-i\fR image_name] [file]
.SH DESCRIPTION
.B flashrom

chips. It can be used to flash BIOS/coreboot/firmware images, for example.
(see
.B http://coreboot.org
for details on coreboot)
.SH OPTIONS

is that flash info is dumped and the flash chip is set to writable.
.TP
.B "\-r, \-\-read"

.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"

see the

README 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>
