No, vlink can be handled before or after ram init, and it isn't even necessary, if no config is done it will default to the slowest operating mode (newer chipsets may bootstrap to higher modes, depending on motherboard design). However, you do have to program the CPU bus registers and all the various dram config registers before ram init. Getting these settings right may be a real pain, depending on what chipset you're dealing with. -Corey -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
