Re: [edk2-devel] [edk2-platforms][PATCH v2] BoardModulePkg/BoardBdsHookLib: Register UiApp as boot option

["Nate DeSimone" <nathaniel.l.desimone@intel.com>]

Hi Benjamin,

The implementation logic looks good. We do have to consider the case of a system without BIOS setup, in which case UiApp will not be present in the image. However, that appears to be well handled by new implementation. If UiApp does not exist in the FV that contains BdsDxe then the file will not be found and the new boot option will not be added.

I do have two comments however.

First, if UiApp does exist in the FV, could you change the F2 hot key to go straight into the setup menu? The hot key is registered here: https://github.com/tianocore/edk2-platforms/blob/c9fff3e9efd2d5daab76b703cc94fd7cbf2ac0b2/Platform/Intel/BoardModulePkg/Library/BoardBdsHookLib/BoardBootOption.c#L472

Normally F2 is used to enter setup but the current implementation is designed to handle the case of a system not having setup rather lazily... it just routes both F2 and F7 to the boot option menu 100% of the time. Could you modify this implementation so that if UiApp exists in the FV, then F2 goes straight into setup instead?

My second comment is kind of a nitpick, we generally use the string L"Enter Setup" for UiApp instead of L"Platform Configuration" and sadly some of the old code has special handling of that string. For example: https://github.com/tianocore/edk2-platforms/blob/c9fff3e9efd2d5daab76b703cc94fd7cbf2ac0b2/Platform/Intel/PurleyOpenBoardPkg/Override/Platform/Intel/MinPlatformPkg/Bds/Library/DxePlatformBootManagerLib/BdsPlatform.c#L1244

Could you please change that string to L"Enter Setup"?

Thanks,
Nate

BootManagerMenuApp is the default PcdBootManagerMenuFile. It allows choosing a boot device, but system configuration is performed in UiApp.
Therefore, un-comment and fix UiApp boot option registration.

Tested, UiApp can be entered through the new boot option.
