an update is available for your BIOS (0160). If you update to this following
https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it
doesn't, could you please both specify what happened, and just provide the
output of the following terminal command:
sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date
Thank you for your understanding.

** Description changed:
Aten CM0264 KVM misbehaves with Ubuntu: it is apparently misdetected as
CD-ROM, causing long delays and all kinds of strange errors, making the
KVM all but unusable. (Disconnecting USB cable from it temporarily
during boot acts as a workaround, albeit a very inconvenient one.)
This happens with 64-bit 10.04 and 12.04 at least (others not tested).
