Hi Jack,
Do the following changes in the Minnowboard BDS to enable
HotKey functionality
*File:* BdsUiLib.c
*File Path:* MinnowBoardPkg/Bds/
*Line No:* 1311 (approximate)
*Function Name:* BdsUiInteractiveMenus()
Comment out the following line
/*
if (PcdGetBool (PcdEnableFastBoot) && (BootMode ==
BOOT_WITH_MINIMAL_CONFIGURATION || BootMode ==
BOOT_ASSUMING_NO_CONFIGURATION_CHANGES)) {
if (gPickList != NULL) {
mEfiBootCallBack (gPickList[0].BootOption);
}
}
*/
In Platform.dsc file Set "PcdPlatformBootTimeOut" pcd to 2 seconds.
This might solve your issue.
You may now press Esc key to interrupt the boot. + / - keys can be used to
navigate through the available boot list.
If you don't press the Esc Key, the Boot Menu will be visible to you, but
only for 2 Seconds as set in PcdPlatformBootTimeOut.
Regards
Vijai Kumar K
