A previous blog discussed the fundamentals of the powerful “BIOS-Level Access” that KVM-over-IP Switches like the Raritan Dominion KX Switches provide. This blog covers more advanced features including: (1) virtual media usage in the BIOS, (2) special KVM features that we have implemented over the years, and (3) BIOS changes that are sometimes necessary to support BIOS usage by KVM switches.
Virtual Media in the BIOS
Virtual Media is a KVM-over-IP Switch function to mount various media such as USB drives, DVD drives, and ISO images from the user’s laptop/PC to a remote computer through the computer’s USB ports. The user can then transfer files, install software, and more. A really nice feature is that these virtual media drives are available in the BIOS, so an IT administrator can even boot an OS from the virtual media drive.
Special KVM Features for BIOS
When we initially implemented virtual media in the Dominion KX II many years ago, users reported problems with virtual media drives in the BIOS, as well as problems with using the keyboard and mouse in the BIOS. We discovered that some BIOS versions did not support USB virtual media, keyboard, and mouse in a standard way.
To solve these issues, we created a few innovative solutions for our Dominion Switches:
With these new features, Raritan’s Dominion Switches now support virtual media in the BIOS and a wide variety of BIOS from multiple computer manufacturers.
BIOS Changes for KVM Switches
While we are on the topic of the BIOS, it is good to mention that sometimes BIOS settings are needed to support the connection of KVM switches. I have come across these situations in my experience:
More information on Raritan KVM switches can be found in the documentation and online help, available on the Technical Support Pages for each product. For more information on your computer’s BIOS, contact the documentation from the manufacturer.
