    I have a Phoenix Award Bios on this system and its loaded full of options, most I understand (Mostly) but some I have alot of doubts about and the manual is nearly useless.

    If anyone can help me out on the right settings for my CMOS, please post ..

    ATI Radeon 9800 pro
    512 2700 RAM 333 speed

    Dram Control Rate (1T command or 2T Command)
    DRam Bust Len (4 or 8)
    Write Recovery Time (3T or 2T)
    AGP Aperture Size (AGP Mode, 128M, or 256M)

    Question, what are midi ports?

    You're asking a little too much. It would take some pages to describe how these settings work, how they interact and potential causes of problems. You should try googling for most of these settings and THEN asking about the remainder in forums like this. hehe "sponge" is a good nick

    Here's a start. BUT find out what they do first

    Dram Control Rate 1T
    AGP Master 1 WS Write and Read Disable
    VLink 8X Support Enable
    System Bios Cacheable Enable
    Video Ram Cacheable Enable
    IDE DMA Transfer Access Enable
    Onchip IDE Channel 0\1 Enable
    Midi Port Address try 300
    midi port IRQ try 5

    Spread Spectrum Disable (contrary to poular belief)
    CPU Clock set at 133

    >CPU Voltage (set at 1.45 v)
    The 2.4B has variable VID leave it at what the BIOS picks up

    Leave DDR voltage (set at 2.60 v)
    Leave AGP Voltage (set at 1.50 v)
    Leave DDRVTT Voltage (set at 1.25 v)
