很多设备都有配置寄存器，BIOS可以基于系统可写内存中的设置向其中写入合理或正确的值。
Many devices have configuration registers to which the BIOS can write reasonable or correct values, based on Settings located in the system's writeable memory.
这意味着您不能使用-fomit - frame - pointer进行编译，所有寄存器向栈中保存都要参照%ebp而不是%esp。
This means that you cannot compile using -fomit-frame-pointer and that any registers that you save on the stack should be done in reference to % ebp instead of % esp.
