Booting a computer using virtual memory

5.2.2Booting 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

5.2.2.1Determining 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 this attached 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 booting 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 server for information on availability or plans of a BIOS revision that will support booting from a composite USB 2.0 device.
