I am still confused by the more basic question of how you are detecting the presence of an 80 conductor cable. You need a GPIO or one of the mechanisms described in the PATA spec from T13. You need that in addition to knowing what the drives support. To know what the drives support you look in their identify device information (also specified by T13, but you can find examples in the kernel or Hale Landis' code) -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
