[QUOTE="harryb2448, post: 635369, member: 42497"] G'day and welcome. Firmware update usually read 4.2.8f1 after correct updating. Have a look at about this mac and see what is shown there as the BOOT ROM version. Also a firmware update should have come with the upgrade itself and Son net recommend, or insist, their upgrade be used. Failing that it could well be a dead CPU. Give Sonnet Technical Support a belt and see what they come up with. [/QUOTE]
