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.
