Setup Program
Setting the Selectable Drive-Startup Sequence
Selectable drive startup (referred to as Boot Sequence on the
Advanced Setup program screen, under the Boot Options choice)
allows you to control the startup sequence of the drives in your
server. Each time you turn on the server, it checks the drives as it
looks for the operating system. The order in which the system
checks the drives is the drive-startup sequence.
In most cases, you do not need to change the default drive-startup
sequence. However, you might want to do so if you are working
with multiple operating systems, or diskette drives of different sizes.
The default drive-startup sequence first checks the primary diskette
drive for a self-starting (bootable) diskette. If one is present, the
operating system or program is loaded from the diskette. If not, the
system then checks the primary hard disk for an operating system.
If one is present, it loads the operating system from that hard disk.
If you start the system from a diskette, the drive that contains the
diskette becomes drive A, regardless of the defined sequence, and
the first hard disk that you select in the startup sequence becomes
drive C.
If you elect to switch the startup sequence of the diskette drives, use
the Swap Floppies selection.
To change the startup sequence:
1. Turn on the server. Be ready to act quickly.
2. After the IBM logo screen appears and then quickly disappears,
you are prompted to Press <F2> to enter SETUP. As soon as
you see that prompt, press F2. If the Setup program screen does
not appear, restart your system and try again.
3. Press the right cursor key to go to the Advanced menu of the
Setup program.
4. Select Boot Options; then, follow the instructions on the screen.
