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.

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.
