Notes for OS Installation

See the following notes requiring attention when installing the OS:

!

Adding a SCSI card to a free slot and connecting a disk to the SCSI card
after the OS installation, might change the numbering of the disk and
prevent an OS boot from that disk.

!

PCI12 slot is set to not run Option ROM BIOS as default. Running
Option ROM BIOS on PCI12 slot requires changing the settings of the
slot with BIOS setup before booting the OS.

EFI Device Path

Each device installed in the system is managed with an “EFI Device Path.” The
following information describes EFI device paths.

See the following examples and Table 2-2 for device path formats for devices
conforming to EDD3.0 specification:

Example: SCSI cards and disks installed on the PCI bus:

Acpi(PNP0A03, 1)/Pci(2|0)/Scsi(Pun0,Lun0)/HD(Part1,SigFF050000)

Example: DVD-ROM device connected to the IDE Secondary channel:

Acpi(PNP0A03,0)/Pci(2|1)/Ata(Secondary,Master)/CDROM(Entry1)
