- Secure the graphics card to your chassis with screws.
4.5 Connexions d'alimentació
Connect the main 24-pin ATX power connector and the 8-pin EPS 12V CPU power connector from your power supply to the motherboard.
4.6 Connectors del panell frontal
Connect your chassis's front panel cables (power button, reset button, USB, audio) to the corresponding headers on the motherboard. Refer to the motherboard diagram for exact locations.
5. Instruccions de funcionament
5.1 Arrencada inicial i configuració de la BIOS/UEFI
- Després de muntar el sistema, connecteu un monitor, un teclat i un ratolí.
- Power on your system. During POST (Power-On Self-Test), repeatedly press the Del or F2 clau per entrar a la utilitat de configuració de la BIOS/UEFI.
- Configure boot order, enable XMP/EXPO for memory, and set other system preferences as needed.
5.2 BIOS Flashback
The BIOS Flashback feature allows you to update the BIOS without a CPU, RAM, or graphics card installed. This is useful for supporting newer CPUs not natively supported by the initial BIOS version.
- Baixeu la darrera BIOS file from the ASRock weblloc web per al model específic de la placa base.
- Canvieu el nom de la BIOS file a
creative.rom(or as specified by ASRock) and save it to the root directory of a FAT32 formatted USB flash drive. - Insert the USB flash drive into the designated BIOS Flashback USB port on the rear I/O panel.
- Ensure the motherboard has power (24-pin ATX connected), but do not power on the system.
- Press and hold the BIOS Flashback button for approximately 3 seconds until the LED starts flashing.
- Release the button. The LED will continue to flash, indicating the BIOS update is in progress. Do not remove the USB drive or power off the system during this process.
- The LED will stop flashing when the BIOS update is complete.
6. Manteniment
Un manteniment regular ajuda a garantir la longevitat i el rendiment òptim de la placa base.
- Neteja: Netegeu periòdicament la pols de la placa base i els components amb aire comprimit. Assegureu-vos que el sistema estigui apagat i desendollat abans de netejar-lo.
