-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
The sil3114 chip has a class code set to something else then IDE by strap resistor. It took me long time to figure out that this chip is otherwise IDE compatible ;) Try attached patch for coreboot which reprograms it back to IDE mode ;) It should start to work - booting from FILO and from Seabios.
