____________________________WARNING____________________________
Erroneously writing to a system EEPROM (like DIMM SPD modules)
can break your system. It will NOT boot anymore so you'll not
be able to fix it.
Reading from 8bit EEPROMs (like that in your DIMM) without using
the -8 switch can also UNEXPECTEDLY write to them, so be sure to
use the -8 command param when required.
Use -f to disable this warning message
