Intel (x86 Ivy+Panther Point) Power Sequence (開機訊號時序)

這篇介紹的是按下電腦開機按鈕到Bios接手之前的訊號時序邏輯, 以Desktop Motherboard為範例

// 開啟電源後，從SIO(super IO)報到南僑
1. PWRBTN# assert (to SIO)
2. SIO assert SB_PWRBTN# to PCH

// PCH和SIO的handshake
3. PCH assert SUS_WARN# to SIO
4. SIO assert SUS_ACK# to PCH

5. PCH de-assertSLP_LAN# 去叫邏輯電路打開 3.3v_ME
6  PCH de-assertSLP_A# 去叫邏輯電路打開 1.05v_ME
7. PCH  de-assert  SLP_S4# 信號去開啟dual power rail (這個power rail是由standby power轉來的)
8. PCH de-assert  SLP_S3# 信號去開啟ATX power的PSON#
9. ATX power 回 ATX_PWROK給PCH
10. PCH發給CPU, DRAM_pwrok 和 CPU_pwrOK，代表VCORE ready
11. PCH de-assert PLTRST# (有些設計是PCIRST#), 接著就開始Reset一些周邊裝置

C# : Show Version

string FileLocate = @"\\Address\Filename.exe";

if (File.Exists(FileLocate) == true)
{
    var versionInfo = FileVersionInfo.GetVersionInfo(FileLocate);
    string version = versionInfo.ProductVersion; //  "1.0.0" as default
    
    string MessageBoxTitle = "Version";
    string MessageBoxContent = version.ToString() + "\n";
    DialogResult dialogResult = MessageBox.Show(MessageBoxContent, MessageBoxTitle, MessageBoxButtons.OK);
}
