Mainboard AV41

No, it does not support ECC memory. AV41 supports PC 100/133 compliant SDRAM up to 1.5GB (un-buffered) capacity only. Also supports PC 100/133 compliant SDRAM up to 3GB (registered) capacity.

After installing the driver for ATI series AGP 4x VGA card on AV41 mainboard, why do I get a blank screen? Then no matter what I do, system powers up but still blank screen.

Please follow the following steps to avoid the problems :

• 1. Disable AGP 4x mode or change to 2x mode in Bios
• 2. Install O.S.
• 3. Install VIA 4-in-1 drivers (4.29V or later)
• 4. Install ATI VGA driver
• 5. Enter to O.S.
• 6. Restart the system and go back to Bios Setup to enable AGP 4x mode.

Adhesive thermal silicone gel such as Shin-Etsu Silicone will set after about 6 hours and form a strong bond between the heatsink and CPU die or other applied surfaces (eg. memory module, chipsets). This type of adhesive thermal compound is strongly not recommended to use on P4 Socket 423/478 CPU die. Since fan heatsink will stick strongly to the P4 CPU die and due to P4 Socket 423/478 ZIF socket structural design, upon removal of the heatsink will force P4 CPU to break apart from the ZIF socket thus damaging both pins on P4 CPU and ZIF socket. Please use non-adhesive thermal compound for P4 CPU only to avoid any damage done to the ZIF socket and P4 CPU.

When upgrading Bios, please extract ZIP file to a bootable floppy Disc, restart system and reboot into pure DOS environment. Type in the following commands: 
awdflash av41biosname.bin /cc/cd/cp/sn/py/r/f
