Question about ASUS P4SGX-MX Motherboard
If you installed an AGP graphics card before your fist boot of the system, you will not receive display. By default the onboard graphics is set to boot display. (If this is the case, remove the AGP graphics card & boot the system). The Asus P4SGX-MX can only use a 4x AGP 1.5volt (only) card.
There is an order of sequences to perform before installing/ adding an AGP graphics card on to the board when the board also uses an integrated graphics card.
First, shut down the system & unplug the power supply from the PC. Connect your monitor to the VGA port at the rear of the board. Remove the AGP card. Re-connect the power supply & boot the system. You should have display? Re-boot the system. As the system starts up press the delete key on the keyboard every 2 seconds. The bios main menu will load. (Open your manual). Go to
section 2.4.3, page 2-20 under Advanced, PCI configuration. Set Primary VGA bios to
[AGP VGA Card]. Save the bios & exit. The system will auto restart. Press & hold the power on/ off button on the PC case until the system shuts off. Unplug the power cord from the PC. Insert the AGP card into the AGP slot. Connect your monitor to the AGP card.
Check all internal data & power cables, (Incase something came loose). Re-connect the power cord & boot the system. You should have display! Install your video software.
If your using the integrated VGA PCI graphics card, go over the bios settings page 2-18 & 2-20.
