谁说随便换BIOS?当然必须是同一个类型的BIOS只是版本不同而已。你不可能拿一个AWARD bios类型去写一个AMI bios类型的主板？hnhuqiong你自以为懂那么就应该明白我的意思，不可能每次都要我再解析一遍？
这个我觉得其是可以的！BIOS只要能支持该主板的配置即可...跟牌子没啥本质联系。主要的是CPU+芯片组+SuperIO等核心部件相关。多数BIOS厂商都拥有很大的支持源码树。AMI的模块化层次管理比较清晰；AWARD代码比较混乱；Phoenix的没见过代码，不过应该是不错的。

; Name: RSDT
;
; Type: Data Array
;
; Description: Root System Description Table
; The Root System Description Table starts with the signature 'RSDT,'
; followed by an array of 32bit physical pointers to the other System Description Tables
; that provide various information on other standards that are defined on the current system.
;
; Referrals: acpi_generate_tables
;
; Notes: The OS locates that Root System Description Table by following the pointer in the
; Root System Description Pointer structure

; Description: The Firmware ACPI Control Structure (FACS) is a structure in read/write

; FACS table will be moved at Org 0 offset of the Type 4 memory
;
; Referrals: acpi_generate_tables

; Notes: For more information about the FADT FIRMWARE_CTRL field, see ACPI 2.0 spec, section 5.2.8,
