HP ROM-Based Setup Utility User Guide

NMI Debug Button
The NMI Debug Button option is a simple toggle setting that enables you to enable debug
functionality when the system has experienced a software lock-up. The NMI Debug Button generates
an NMI to allow the use of the OS debugger.
NOTE: When enabled, pressing the NMI Debug Button on the system board during normal OS
operation generates a Blue-Screen Trap, ABEND, or Panic, and halts the system.
Virtual Install Disk
The virtual install disk is a holding place within the system ROM that contains embedded boot
drivers (such as SCSI or RAID controller drivers) that may be necessary to complete the operating
system installation. Typically, boot drivers that are placed in the virtual install disk are either not
included as part of the operating system media or are updated for new controllers. Supported
operating systems automatically find these drivers, eliminating the need for user intervention. To
further optimize the system, HP recommends updating these boot drivers to the latest version after
the OS install.
Secondary IDE Channel Support
The Secondary IDE Channel Support option is a toggle setting that enables or disables the secondary
IDE channel. When enabled, an additional IDE device can be connected to the secondary IDE
channel.
BIOS Enhanced RAID
The BIOS Enhanced RAID feature is a toggle setting that, when enabled, analyzes the Linux data
on installed hard drives for failure information. Based on the analysis, the system ROM automatically
chooses which hard drive to boot.
Node Interleaving
The Node Interleaving feature requires all nodes to have equal memory sizes when enabled.
Enabling Node Interleaving may affect OS performance.
