Dell PowerEdge 6400 - Manual (Page 73)

Diskette Drive A and Diskette Drive B identify the type of diskette drive installed in your computer. With the standard cabling configuration,
diskette drive A (the boot diskette drive) is the 3.5-inch diskette drive installed in the top externally accessible drive bay.
The settings always match the physical locations of the drives in your computer —the first drive listed on Page 1 of the System Setup screens is the
top drive in your computer.
The settings are:
l
3.5 Inch, 720 KB
l
3.5 Inch, 1.44 MB
l 5.25 Inch, 360 KB
l 5.25 Inch, 1.2 MB

Num Lock
Num Lock determines whether your system boots with the Num Lock mode activated on most keyboards (it does not apply to 84-key keyboards).
When Num Lock mode is activated, the rightmost bank of keys on your keyboard provides the mathematical and numeric functions shown at the
tops of the keys. When Num Lock mode is turned off, these keys provide cursor-control functions according to the label on the bottom of each key.
Speaker
Speaker determines whether the integrated speaker is On (the default) or Off. Rebooting the system is required for the changes to take effect.
OS Install Mode
The OS Install Mode determines the maximum amount of memory available to the operating system. On sets the maximum memory available to
the the operating system to 256 megabytes (MB). Off (default) makes all of the system memory available to the operating system.
Processor 1, Processor 2, Processor 3, and Processor 4
Processor 1, Processor 2, Processor 3, and Processor 4 display the version or stepping number of each processor slot in the system. These
options have no user-selectable settings.
Processor Speed
Processor Speed displays the internal microprocessor speed.
Processor Serial Number
Processor Serial Number enables or disables the processor serial number feature. This option has the following settings:
l Disabled (default)
l Enabled
Keyboard Errors
Keyboard Errors enables or disables reporting of keyboard errors during the power-on self-test (POST), which is a series of tests that the system
performs on the hardware each time you turn on the system or press the reset button.
This option is useful when applied to self-starting servers or host systems that have no permanently attached keyboard. In these situations,
selecting Do Not Report suppresses all error messages relating to the keyboard or to the keyboard controller during POST. This option does not
affect the operation of the keyboard itself if a keyboard is attached to the computer.
Boot Sequence
Boot Sequence can be set to Diskette First (default) or to Hard Disk Only.
The term boot refers to the system's start-up procedure. When turned on, the system "bootstraps" itself into an operational state by loading into
memory a small program, which in turn loads the necessary operating system. Boot Sequence tells the system where to look for the files that it
needs to load.

Diskette First
Selecting Diskette First causes the system to try booting from drive A first. If the system finds a diskette that is not bootable in the drive or
finds a problem with the drive itself, it displays an error message. If it does not find a diskette in the drive, the system tries to boot from the
hard-disk drive (drive 0). If the hard-disk drive is not bootable, the system tries to boot from the Plug and Play network adapters in the order
found.
