NEC 1080Xd manual OS Boot from EFI Shell

OS Boot from EFI Shell

You can boot the OS from the EFI Boot Manager. You can also boot the OS by entering commands from the EFI Shell.

An example follows for booting the OS from the SCSI hard disk drive in a hardware configuration containing:

!IDE DVD-ROM (Master)

!SCSI HDD: OS boot disk

!External LAN card built into the Expansion PCI slot.

Note: Cards are available if they are supported by the application programs or OS.

1.Specify the file system. Change the current file system to the file system with the connected boot device by entering the device at the Shell prompt.

For the example in the following screen (see Figure 2-14), enter fs0: for the fs0 boot device.

Shell> map		Boot device
Device mapping table
fs0	: Acpi(PNP0A03,3)/Pci(20)/Scsi(Pun0,Lun0)/HD(Part1,Sig0A7C0000)
fs1	: Acpi(PNP0A03,0)/Pci(21)/Ata(Primary,Master)/CDROM(Entry1)
blk0	: Acpi(PNP0A03,3)/Pci(20)/Scsi(Pun0,Lun0)
blk1	: Acpi(PNP0A03,3)/Pci(20)/Scsi(Pun0,Lun0)/HD(Part1,Sig0A7C0000)
blk2	: Acpi(PNP0A03,3)/Pci(20)/Scsi(Pun0,Lun0)/HD(Part2,Sig0A7C0000)
blk3	: Acpi(PNP0A03,0)/Pci(21)/Ata(Primary,Master)
blk4	: Acpi(PNP0A03,0)/Pci(21)/Ata(Primary,Master)/CDROM(Entry1)

Shell> fs0:

Enter fs0:
