Settings of CMOS and/or NVRAM Are Cleared
You can clear the settings in CMOS/NVRAM by using BIOS virtual DIPSW, which
can be specified by the “su” command of iSP. For BIOS virtual DIPSW, any
hexadecimal value of 8 digits can be specified. Setting values other than the ones listed
in the table below cannot be used because they are already reserved. In addition, when
a clear operation is performed, the setting value is automatically cleared to “0.” It is not
necessary to set “0” as a clear operation.
See the section “BIOS Virtual Dip Switch” later in this chapter and Table 4-28 for more
information about the Virtual DIP switch settings.

Adding or Deleting a Boot Device
To add or delete a boot device, you must enable or disable the Option ROM expansion
of the PCI card to which the boot device is connected. To add a boot device, specify to
“enable the Option ROM expansion of the PCI card that controls the boot device” in the
Option ROM submenu in the Advanced menu of Setup. To delete a boot device, specify
to “disable the Option ROM expansion of the PCI card” in the same submenu.
“Option ROM expansion” — to store the Option ROM data of the PCI card in memory.
