+Flash BIOS without DOS/Windows:
+Dump flash info and set the flash chip to writable:
+# flashrom

+Backup the original BIOS:
+# flashrom -r backup.bin

+Notice: the following step will overwrite your current BIOS!
+So make sure you really know what you are doing.
+
+Flash the BIOS image:
+# flashrom -wv newbios.bin
