You need to make and run the program util/getpir (using the original BIOS, running Linux) to make the file irq_tables.c, then copy that file into the mainboard directory, and set the option HAVE_PIRQ_TABLE=1. Linuxbios when it starts will copy this file into the shadowed RAM at 0xF0000, where Linux can find it during startup. This allows Linux to route the irqs. -Steve _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
