Dell OptiPlex GX100 - Manual (Page 90)

Selecting Diskette Drive A: as the first device 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 next device in the boot sequence list.
Hard-Disk Drive
Selecting Hard-Disk Drive causes the system to attempt to boot first from the hard-disk drive and then from the next device in the boot sequence
list.
IDE CD-ROM Device
Selecting IDE CD-ROM Device causes the system to try booting from the CD-ROM drive first. If the system finds a CD 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 CD in the drive, the system tries to boot from the next
device in the boot sequence list.
MBA UNDI
Selecting MBA UNDI allows the system to boot from the network server. The MBA UNDI option appears under Boot Sequence only if the
Network Interface Controller option is set to On w/ MBA. If the Network Interface Controller option is set to On or Off, set it to On w/ MBA
and then press to save the change and reboot the system. MBA UNDI then appears under Boot Sequence.
When you select this option, the system prompts you to press at the Dell logo screen during system boot. A menu then appears
that allows you to select PXE, RPL, BootP, or NetWare as the active boot mode. If a boot routine is not available from the network server, the
system boots from the next device in the boot sequence list.
CPU ID
CPU ID provides the manufacturer's identification code for the installed microprocessor.
CPU Speed
CPU Speed indicates the processor speed at which your system boots.
Press the left- or right-arrow key to toggle the CPU Speed option between the resident microprocessor's rated speed (the default) and a lower
compatibility speed, which lets you accommodate speed-sensitive application programs. A change to this option takes effect immediately
(rebooting the system is not required).
To toggle between the rated processor speed and the compatibility speed while the system is running in real mode, press <\>. (For
keyboards that do not use American English, press <#>.)
