5.2.2 Booting a computer using virtual memory
In many cases the virtual media feature can boot an attached computer from a device
attached to the USB port on the KVM s3-1621 or KVM s3-1641 appliance. Most
computers with a USB port can use virtual media; however, limitations in some USB
media devices and the BIOS of some computers might prevent the computer from
booting from a USB device attached to the KVM s3-1621 or KVM s3-1641 appliance.
Booting from a virtual USB device is dependant on the target server supporting booting
from an external composite USB device. It also requires a CD of the operating system
that supports external USB 2.0 booting. The following is a partial list of operating
systems that support booting from an external USB 2.0 device:
• Windows Server 2003
•Windows XP
• Windows 2000 Server with Service Pack 4 (SP4) or later
5.2.2.1 Determining if your computer can be booted from virtual media
Connect a USB CD drive to the KVM s3-1621 or KVM s3-1641 appliance with an
operating system installation CD that is bootable, and map it to the target server.
Reboot the target server to determine if it will boot from t his a tt ached CD drive. The
BIOS might need to be set to boot from an external USB device.
If the target server will not boot, connect the USB CD drive to a USB port on the
target server and reboot the target server. If the target server successfully boots
from the CD drive, the BIOS is not supporting booting from a composite USB 2.0
switch. Check the support Web site from the target server manufacturer to
determine if a later BIOS is available that might support booting from a composite
USB 2.0 device. If so, update the BIOS and retry.
If the target server is not capable of booti ng from an external USB 2.0 device, try
the following methods to remotely boot this target server:
• Some BIOS versions provide an option to limit USB speeds. If this option is
available to you, change the USB port setting to “USB 1.1” or “Full Speed”
mode, and try booting again.
-or-
• Insert a USB 1.1 card, and try booting again.
-or-
• Insert a USB 1.1 Hub between the KVM-IA and the target server, and try
booting again.
-or-
• Contact the manufacturer of the target ser ver for information on availability o r
plans of a BIOS revision that will support booting from a composite USB 2.0
device.
