Request to unlockpackard Bell MS7301 BIOS

Hi,  I have been given a Packard Bell PC model MS7301 (Cuba) with 1Mb Ram, according to ram checkers I should be able to use 2GB DDR2 667 Mhz PC2-530 PC2-5400 RAM.  However the BIOS doesn't recognize the new ram and reports the old (1Mb). Could the BIOS be unlocked to accept the new RAM.  I have attached a copy of the BIOS.
