Thank you for rewriting this in a much less invasive way. I have a few comments, but I hope they are simple enough that they can be addressed quickly.

This would let the entire body of this function fit on one screen page, as well as giving the ability to provide a descriptive function name that explains what the effect of the loop does without having to read through it all. (It would also mean that temporary variables used only in the for-loop would not take up space at the start of this function.) This is nearly exactly the cut-off point for me - if there was only a couple of more lines of code in the loop, I would always ask for it to be broken out. > + > + if (NumberFileSystemHandles != 0) { > + FreePool (FileSystemHandles); > + } > + > + FreePool (UsbPathTxt); > + > + return Result; > +} > + > +STATIC > +UINT16 > +GetBBSTypeByDevicePath ( > + IN EFI_DEVICE_PATH_PROTOCOL *DevicePath > + ) > +{ > + VENDOR_DEVICE_PATH *Vendor; > + EFI_DEVICE_PATH_PROTOCOL *Node; > + UINT16 Result; > + > + Result = BBS_TYPE_UNKNOWN; > + if (DevicePath == NULL) { > + return Result; > + } > + > + Node = DevicePath; > + while (!IsDevicePathEnd (Node)) { > + switch (DevicePathType (Node)) { > + case MEDIA_DEVICE_PATH: > + if (DevicePathSubType (Node) == MEDIA_CDROM_DP) { > + Result = BBS_TYPE_CDROM; > + } > + break; > + > + case MESSAGING_DEVICE_PATH: > + switch (DevicePathSubType (Node)) { But nested switch statements are always too hard to read in one place, so please turn this inner one into a helper function. > + case MSG_MAC_ADDR_DP: > + Result = BBS_TYPE_EMBEDDED_NETWORK; > + break; > + > + case MSG_USB_DP: > + Result = GetBBSTypeFromUsbPath (DevicePath); > + if (Result == BBS_TYPE_UNKNOWN) { > + Result = BBS_TYPE_USB; > + } > + break; > + > + case MSG_SATA_DP: > + Result = BBS_TYPE_HARDDRIVE; > + break; > + > + case MSG_VENDOR_DP: > + Vendor = (VENDOR_DEVICE_PATH*)(Node); > + if ((&Vendor->Guid) != NULL) { > + if (CompareGuid (&Vendor->Guid, &((EFI_GUID)DEVICE_PATH_MESSAGING_SAS))) { > + Result = BBS_TYPE_HARDDRIVE; > + } > + } > + break; > + > + default: > + Result = BBS_TYPE_UNKNOWN; > + break; > + } > + break; > + > + default: > + Result = BBS_TYPE_UNKNOWN; > + break; > + } > + > + if (Result != BBS_TYPE_UNKNOWN) { > + return Result; > + } > + > + Node = NextDevicePathNode (Node); > + } > + > + return Result; > +} > + > +STATIC > +EFI_STATUS > +GetBmcBootOptionsSetting ( > + OUT IPMI_GET_BOOT_OPTION *BmcBootOpt > + ) > +{ > + EFI_STATUS Status; > + > + Status = IpmiCmdGetSysBootOptions (BmcBootOpt); > + if (EFI_ERROR (Status)) { > + DEBUG ((DEBUG_ERROR, "Get iBMC BootOpts %r!\n", Status)); > + return Status; > + } > + > + if (BmcBootOpt->BootFlagsValid != BOOT_OPTION_BOOT_FLAG_VALID) { > + return EFI_NOT_FOUND; > + } > + > + if (BmcBootOpt->Persistent) { > + BmcBootOpt->BootFlagsValid = BOOT_OPTION_BOOT_FLAG_VALID; > + } else { > + BmcBootOpt->BootFlagsValid = BOOT_OPTION_BOOT_FLAG_INVALID; > + } > + > + Status = IpmiCmdSetSysBootOptions (BmcBootOpt); > + if (EFI_ERROR (Status)) { > + DEBUG ((DEBUG_ERROR, "Set iBMC BootOpts %r!\n", Status)); > + } > + > + return Status; > +} > + > +STATIC > +VOID > +RestoreBootOrder ( > + VOID > + ) > +{ > + EFI_STATUS Status; > + UINT16 *BootOrder; > + UINTN BootOrderSize; > + > + GetVariable2 (L"BootOrderBak", &gOemBootVaraibleGuid, (VOID **) &BootOrder, &BootOrderSize); > + if (BootOrder == NULL) { > + return ; > + } OK, here is the only _functional_ feedback I have on this implementation: I would prefer if this solution did not use an environment variable to keep track of whether "BootOrder" had been modified or not.

Think about this case: suppose that the board was reset after the BootOrder variable was set, but not run to ReadyToBoot, The following code will restore BootOrder variable from BootOrderBak vairiable in next boot. PlatformBdsInit ( VOID ) { //Signal EndofDxe Event EfiEventGroupSignal(&gEfiEndOfDxeEventGroupGuid); // restore BootOrder variable if necessary. RestoreBootOrder(); The other commends are modified.
