Intel Desktop Board DQ57TML Specification Update

Intel Desktop Board DQ57TML Specification Update 7

Errata

Errata 1 and 2 below have been fixed in BIOS version TMIBX10H.86A.0038.

1. Disabling USB Boot Still Allows USB Devices to be Booted

Problem: If USB Boot is disabled in BIOS Setup, it does not prevent attached bootable

USB devices from booting. Default setting is Enabled.

Implication: The USB Boot Disable setting is effectively ignored. Any attached bootable

USB device will still be booted.

Workaround: A fix has been found and will be implemented in the next BIOS update.

Status: Fixed.

2. Enabling USB Backwards Compatibility Mode disables some

USB Ports

Problem: The current implementation of the Intel Desktop Board DQ57TML causes

some USB ports to be disabled in the operating system whenever an Intel

Core™ processor with Intel

Graphics Technology is used in USB Backwards

Compatibility Mode.

Implication: Some USB devices may fail to work unless USB Backwards Compatibility Mode

is enabled. However, certain Intel

vPro™ Technology features, such as KVM

Redirection, require this mode to be disabled in order to function properly.

You cannot use both KVM Redirection and USB Backwards Compatibility Mode

concurrently.

Workaround: A fix has been found that will allow Intel

Core™ processors with Intel

Graphics Technology to be used in USB Backwards Compatibility Mode with all

USB ports functional. It will be implemented in the next BIOS update.

Status: Fixed.

3. Multiple Insert and Removal Cycles of a USB Device May

Disable all USB Ports

Problem: The USB subsystem may become disabled after several insertion and removal

cycles of a single USB device when no other USB devices are connected. The

failure occurs when running Microsoft Windows* XP and it may require a

system reboot. Both Microsoft Windows Vista* and Microsoft Windows 7

operating systems do not appear to exhibit this failure.



Workaround: Enabling USB Backwards Compatibility Mode in the BIOS menu may reduce

the occurrence or alleviate this issue.

Status: No Fix.
