Notes:

Note! Some steppings might require updated BIOS/microcode to work properly. Specific mainboard revisions require specific processor cards in combination with compatible processors to function. As an example you cannot simply use Sabre processors on the Sapphire Red processor cards. The 375-0009 board shipped with the 501-4379 512KB Cache Sabre processor card. The fastest Sabre processor the 375-0009 board supports is the 2MB Cache 501-5222 360Mhz Sabre. The fastest Sapphire Red the board can run with (depends on your boards quality) is the 2MB L2 Cache 501-5149 at 440Mhz. Support for Sapphire Red processors (250nm) requires newer OpenBoot firmware (at least 3.19v4.). For more details refer to
