Dear All, I meet a problem that after I remove the following drivers in dsc and fdf , MdeModulePkg/Bus/Scsi/ScsiBusDxe/ScsiBusDxe.inf MdeModulePkg/Bus/Scsi/ScsiDiskDxe/ScsiDiskDxe.inf
The boot option of UEFI SATA DVD-ROM is losted in UIAPP. Is it a designed behavior? In shell, devtree of failed case(without SCSI driver) showed the following info: Ctrl[D8] PciRoot(0x0)/Pci(0xF,0x0) Ctrl[E6] PciRoot(0x0)/Pci(0xF,0x0)/Sata(0x3,0xFFFF,0x0) Ctrl[E7] PciRoot(0x0)/Pci(0xF,0x0)/Sata(0x3,0xFFFF,0x0)/HD(1,GPT,4362629B-C2C8-40CD-BAEA-1D905100EA32,0x800,0x100000) Ctrl[E8] PciRoot(0x0)/Pci(0xF,0x0)/Sata(0x3,0xFFFF,0x0)/HD(2,GPT,3DDA8351-6EC4-4761-B240-A8BA82E6EFE8,0x100800,0x7EF6000) Ctrl[E9] PciRoot(0x0)/Pci(0xF,0x0)/Sata(0x3,0xFFFF,0x0)/HD(3,GPT,0E47B02D-3C55-4BB5-8582-042471DE137E,0x7FF6800,0x5F9E000) In shell, devtree of passed case(with SCSI driver) showed the following info: Ctrl[E4] Sata Controller Ctrl[F3] KINGSTON SHFS37A120G Ctrl[F5] FAT File System Ctrl[F6] PciRoot(0x0)/Pci(0xF,0x0)/Sata(0x3,0xFFFF,0x0)/HD(2,GPT,3DDA8351-6EC4-4761-B240-A8BA82E6EFE8,0x100800,0x7EF6000) Ctrl[F7] PciRoot(0x0)/Pci(0xF,0x0)/Sata(0x3,0xFFFF,0x0)/HD(3,GPT,0E47B02D-3C55-4BB5-8582-042471DE137E,0x7FF6800,0x5F9E000) Ctrl[F4] SCSI Disk Device Thanks in advance _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
