Start options: Start options take effect when you start the server. You can select keyboard operating characteristics, such as the keyboard speed. You also can specify whether the keyboard number lock (NumLock) starts on or off. You also can enable the server to run in disketteless and monitorless operation. You can specify the startup sequence the server is to use to determine the device from which the operating system loads. For example, you can define a startup sequence that checks for a CD-ROM, then checks an installed hard disk drive, and then checks a network adapter. Attention: If the CD-ROM drive contains a startable CD, you must remove the CD if you want to use a startup sequence that begins with a startable diskette. You can enable a virus-detection test that checks at startup for changes in the master boot record. You also can also choose to run POST in the enhanced mode or in the quick mode. Select Start Options; then, use the Left Arrow (←) or Right Arrow (→) key to advance through each data field.

Start options:
Start options take effect when you
start the server.
You can select keyboard operating characteristics, such as
the keyboard speed.
You also can specify whether the
keyboard number lock (NumLock) starts on or off.
You
also can enable the server to run in disketteless and
monitorless operation.
You can specify the startup sequence the server is to use
to determine the device from which the operating system
loads.
For example, you can define a startup sequence
that checks for a CD-ROM, then checks an installed hard
disk drive, and then checks a network adapter.
Attention:
If the CD-ROM drive contains a startable CD,
you must remove the CD if you want to use a startup
sequence that begins with a startable diskette.
You can enable a virus-detection test that checks at
startup for changes in the master boot record.
You also
can also choose to run POST in the enhanced mode or in
the quick mode.
