Bin:
  Why remove FreePool (Blt)? It is still used.  

Thanks

Hi Liming,

In BootLogoEnableLogo() function, the FreePool(Blt) function will never be called, some Blt related code as below:

a. Blt = NULL;  -> Step 1, Blt was initialized.
......
b.    if (Blt != NULL) {  \
      FreePool (Blt);      -- Step 2, Blt was checked, the judgment is always false.
    }                                    /

c.    Blt = Image.Bitmap;  Step 3, Blt get an valid value.

>From above, I think we can remove this if judgment.

Best Regards,
Bell Song

Bell,
FreePool (Blt) purposely frees the pool of Image.Bitmap, which was returned from previous loop. It's useful.

Thanks/Ray
