对应的BIOS版本是P0C05
准备
下载这个目录下面的文件，需要使用H2OUVE.exe进行BIOS的读取与写入
读取
对于DVMT，需要修改
SaSetup 区域的值后面的命令都需要使用管理员身份
读取 SaSetup 中的值
-gv 是读取， -sv 是写入./h2ouve -gv SaSetup_var.txt -n SaSetup读取 CpuSetup 中的值
./h2ouve -gv CpuSetup_var.txt -n CpuSetup修改
DVMT
0xDF 块的值默认为 0x01 将其修改为 0x02 设置DVMT为64MB[01C] "SaSetup"

DVMT 和 CFG Lock
DVMT和CFG是参考网上对MX250的修改文档并结合IFR得到的
在黑果下可以正常使用 1680x945、1536x864 等大于 1440x810 的分辨率的
SpeedShift 和 Voltage Unlock
SpeedShift和Voltage Lock是结合MX150需要修改的部分（SpeedShift 和 Voltage）加上IFR得到的，这个不保证效果。但是实际上SpeedShift是开起来了
但是电压的话，使用XTU没有成功启动过，提示可能有其他的优化软件正在运行，ThrottleStop没有尝试。XTU版本 6.4.1.19、6.4.1.24
参考对于 MX250 的文档是
里面有提到如何提取BIOS并得到对应的参数的说明，IFR就是从这里面提取到的
