    System BIOS 8.4.1 System ID and ROM Type Diagnostic applications can use the INT 15, AX=E800h BIOS function to identify the type of system. This function will return the system ID in the BX register. Systems have the following IDs and ROM family types: Table 8-3 System ID Numbers System (Form Factor)
  • Page 89 System BIOS 8.5 SMBIOS In support of the DMI specification, PnP functions 50h and 51h are used to retrieve the SMBIOS data. Function 50h retrieves the number of structures, size of the largest structure, and SMBIOS version. Function 51h retrieves a specific structure. This system supports SMBIOS version 2.5 and the structure types listed in the following table: Table 8-3 SMBIOS Functions...

  • Page 90: Usb Legacy Support

    System BIOS 8.6 USB Legacy Support The system BIOS ROM checks the USB port, during POST, for the presence of a USB keyboard. This allows a system with only a USB keyboard to be used during ROM-based setup and also on a system with an OS that does not include a USB driver.
