UEFI : Shell Command & Information

EFI Shell "不" Support exFat / NTFS, 做成此類File System的碟機，只會看到有安裝BlkIo Protocol但看不到增加File system節點, 以下在shell底下研究map指令的輸出結果

從實驗的結果來看，幾個blockio handle的數量會等於partition的數量加上device的數量
幾個可被Uefi recognize的FileSystem(ex: fat32) 就會產生幾個 fs節點

USB Uefi Boot disk

<note>
HD(PartX,SigY)
Partition X on a disk with signature Y
Pci(1|0)
device/slot number 1
function number 0

USB Uefi Boot disk + 1 Sata Without Partition => No Sata Hard Disk was found, But found another BlockDevice

USB Uefi Boot disk + 1 Sata With 1 Partition (exFat) => exFat can not recognize by UEFI, so no other fs was found but do found Harddisk (MBR)
