You probaly include the #define DISABLE_INTERNAL_DEVICE config option.
Use normal BIOS to select
what ever internal devices you want. Use "lspci -xxx -s 0:1.0" to find
out the value of register 0x7c of LPC
bridge. Change the line in "mov $0x7c0e, %ax" in sis/730/raminit.inc to
the value your got.
#ifdef DISABLE_INTERNAL_DEVICES
movw $0x7c0e, %ax # Writting undocumented LPC register
write_lpc_register:
/* Input: AH - register number. AL - register value. */
movl $LPC_BRIDGE_BASE_ADDR, %edx
movl %eax, %ebx # Save %eax to %ebx.
movzbl %bh, %eax # add register address to
addl %edx, %eax # PCI base address
movw $PCI_COMMAND_PORT, %dx
outl %eax, %dx
movw $PCI_DATA_PORT, %dx
andb $0x03, %al
addb %al, %dl
movb %bl, %al
outb %al, %dx
#endif /* DISABLE_INTERNAL_DEVICES */
