Interrupt assignment of the slot connectors on the bus board
Changes and supplements to section 8.5.4.2 of the operating instructions.
Note
All system resources (hardware addresses, memory allocation, interrupt assignment, DMA channels) are assign
ed
dynamically by the BIOS or the Windows operating system, depending on the hardware equipment, drivers, installed
expansion cards and connected external devices.
Assignment is automatic and depends on the demanded resources of the connected devices and the inserted modules. Due
to this configuration dependency, clear statements can only be made by determining them in relation to the system in the
final configuratio
n. Resources may be viewed as follows under Windows:
Press the "Windows key" and "R" simultaneously.
The "Run" dialog box opens.
Enter "msinfo32" in the "Open" field.
3. Confirm your entry with "OK".
Change to section 8.6.5 of the operating instructions.
The change is valid as of BIOS V19.02.06.
The default setting of the DisplayPort audio device has been changed from "Enabled" to "Disabled".
Note
You have to change the following BIOS setting to "Enabled" if you want to use the audio function of the DisplayPort monitor:
Advanced > Video Configuration > Internal Graphic Device > DP
