-As you remember the entry point for our UEFI programs is:
-
-```
-EFI_STATUS
-EFIAPI
-UefiMain (
-  IN EFI_HANDLE        ImageHandle,
-  IN EFI_SYSTEM_TABLE  *SystemTable
-  )
-```
-
-The passed structure `EFI_SYSTEM_TABLE` looks like this according to UEFI specification:
-
-```
-typedef struct {
- EFI_TABLE_HEADER Hdr;
- CHAR16 *FirmwareVendor;
- UINT32 FirmwareRevision;
- EFI_HANDLE ConsoleInHandle;
- EFI_SIMPLE_TEXT_INPUT_PROTOCOL *ConIn;
- EFI_HANDLE ConsoleOutHandle;
- EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL *ConOut;
- EFI_HANDLE StandardErrorHandle;
- EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL *StdErr;
- EFI_RUNTIME_SERVICES *RuntimeServices;
- EFI_BOOT_SERVICES *BootServices;
- UINTN NumberOfTableEntries;
- EFI_CONFIGURATION_TABLE *ConfigurationTable;
-} EFI_SYSTEM_TABLE;
-```
-
-We've already used most of the fields of this structure. Now it is time to peek inside these fields:
-```
-UINTN NumberOfTableEntries;
-EFI_CONFIGURATION_TABLE *ConfigurationTable
-```
-According to the UEFI spec:
-```
-NumberOfTableEntries	The number of system configuration tables in the buffer ConfigurationTable.
-ConfigurationTable	A pointer to the system configuration tables. The number of entries in the table is NumberOfTableEntries.
-```
-
-As for EFI_CONFIGURATION_TABLE type:
-```
-EFI_CONFIGURATION_TABLE
-
-Summary:
-Contains a set of GUID/pointer pairs comprised of the ConfigurationTable field in the EFI System Table.
-
-typedef struct{
- EFI_GUID VendorGuid;
- VOID *VendorTable;
-} EFI_CONFIGURATION_TABLE;
-
-```
-
-Let's create a simple program `ShowTables` to look at tables referenced by this structure in OVMF:
-```
-#include <Library/UefiBootServicesTableLib.h>
-#include <Library/UefiLib.h>
-
-EFI_STATUS
-EFIAPI
-UefiMain (
-  IN EFI_HANDLE        ImageHandle,
-  IN EFI_SYSTEM_TABLE  *SystemTable
-  )
-{
-  for (UINTN i=0; i<SystemTable->NumberOfTableEntries; i++) {
-    Print(L"%g, %p\n", SystemTable->ConfigurationTable[i].VendorGuid,
-                       SystemTable->ConfigurationTable[i].VendorTable);
-  }
-  return EFI_SUCCESS;
-}
-```
-
-Build and execute it under OVMF:
-```
