Each mainboard usually has an early uart setup located in auto.c or cache_as_ram_auto.c. For example the Serengeti-Cheetah has the following lines. w83627hf_enable_serial(SERIAL_DEV, TTYS0_BASE); uart_init(); console_init(); Marc -- Marc Jones Senior Firmware Engineer (970) 226-9684 Office mailto:[EMAIL PROTECTED] http://www.amd.com/embeddedprocessors -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
