20.1.2 FLASHROM.COM – Flash ROM Device Update Utility
FLASHROM.COM is used to update the contents of a Flash ROM device with a new version of GeodeROM or equivalent
boot loader.
Example of usage:
"FlashROM file_name" [Flash & clear CMOS]
The following displays the command line options supported by versions 8.00 and newer of FLASHROM.COM:
FlashROM: Version 8.11
Platform = unknown/unknown
FlashROM: Version 8.11
FlashROM flash updates Geode-based systems that have one of the following ROMs installed:
Options:
FLASHROM.COM – The “/D” Command Line Argument
The “/D” command line argument prevents FLASHROM.COM from clearing the contents of the RTC CMOS RAM following
the completion of the Flash ROM update. This argument is required if the caller wants to preserve the current CMOS set-
tings when updating the system Flash ROM device.
FLASHROM.COM – The “/N” Command Line Argument
The “/N” option prevents FLASHROM.COM from displaying sign-on/status messages during the Flash update procedure.
FLASHROM.COM – The “/R” Command Line Argument
The “/R” option instructs FLASHROM.COM to read the contents of the Flash device into the file “file_name” as specified by
the user. FLASHROM determines the size of the output file by first “ID”-ing the installed Flash part and retrieving its size
from an internal table.
FLASHROM.COM – The “/C” Command Line Argument
The “/C” option instructs FLASHROM to clear the contents of the RTC CMOS RAM. This feature is useful for enabling
options that have been newly introduced to the system firmware and would otherwise not get enabled automatically. The
“/C” option can be used in conjunction with any command line option other than “/D” (Don’t clear CMOS RAM).
FLASHROM.COM – The “/I” Command Line Argument
The “/I” option instructs FLASHROM.COM to display the manufacturer and type of installed Flash ROM device.
