#############################################################################
Mainboard	: B0742_PUZZLE-1100-A1-MB
System          : Z0803_PUZZLE-1100
Chipset		: Amston Lake
=============================================================================
Note:
1. This BIOS project can support Amston Lake, Twin Lake, and Alder Lake-N CPUs.
2. This project has two types of SKUs: 
   a. SKUs with a FAN.
   b. SKUs without a FAN.
3. IPMI need used [iRIS4-M467].
4. EC firmware is included in the master SPI flash.
   -> Running the 'GO' command will update the BIOS and EC firmware in the EFI shell.
5. COM Port 3 LDN needs to be activated.
   -> UART3 is used by EC.
6. Some Amston Lake CPU will trigger cold reset when pressing Ctrl+Alt+Del.(Ex: x7433RE).
7. On Windows 11, the LAN I226 must use the [NDIS driver].
8. COM Port 2 is used by BMC SOL.
