This problem is related to the Voodoo Banshee driver. The newest driver provided by 3Dfx on its website is 1.04.0002-09-2000 and it cannot solve this problem. Thus, GA-630 cannot support S3 under WIN ME due to its driver's limitaion or one can use S3 only by using WIN ME built-in Standard VGA driver.
For 965P-DQ6、965P-DS4、965P-DS3、965P-S3 motherboard, if the memory setting is not the chipset spec of 800/ 667/533 MHz in the BIOS setting during system installation, then the system will re-write the initial motherboard parameter when the first boot after BIOS seeting. After the re-write is done, the system will reboot. The shutdown and reboot after the first power on is normal situation.
