    Question
    On the P4IBMS BIOS ver 1.0D with an ATI Xpert 2000 Pro (Rage 128 Pro Ultra chipset) video card installed the system will not successfully recover from a Suspend To Ram. The system suspends fine, then when the power button is pressed to wake the system, the screen fills with garbage and the system reboots. In the BIOS when S1 is selected in place of S3, the system works. The same ATI video card works on ASUS and Giga-Byte boards with the Intel i82845 chipset. The operating systems I have tried are Windows 2000 Pro (Service Pack 2) and Windows XP Pro. 


    Answer
    V1.0e BIOS fixed
