    Hi everyone

    Since I bought the motheboard I'm using right now, almost a year and a half ago, and I've scratching my head real hard about three subtle and incomprehensible options. But first let me tell you about my machine's specs:

    1. Processor: Pentium 4, 3.2 GHz, with hyperthreading.
    2. Motherboard: Gigabyte GA-i8775PE, based on intel's i865PE chipset.
    3. RAM: 3GB Kingstone's 3200 DDRAM, non-ECC, 2 stick each one Gigabyte, and another two sticks each 512 MB
    4. Monitor: Viewsonic 20" LCD VX2025_wm monitor
    5. Video Card: Nvidia 7800 GS by BFG.
    6. Sound Card: Creative F-xi platinum sound card
    7. speaker system: Logitech z5500 5.1 digital speakers.
    8. Hard drives: Two SATA hard drives, 250 GB each, by Western Digital.

    I'm using the latest version of the bios available from Gigabyte's website, version F6. The three options puzzling me are:

    1. PSB parking.
    2. Dynamic Paging mode.
    3. Fast Chip select.

    I would really appreciate any comment, or even the time spent reading about problem.

    Best Regards

    I'm not sure if these were still open questions or not but... some additional options and question:

    "Init Display First:" will also have "onboard" as an option on the nForce 410 (and above) chipsets. Sets the GPU you want the computer to boot with.

    "Hammer Fid Control:" This is your CPUs frequency multiplier. This is what was called "FSB" is multiplied by to provide your CPU clock speed. Sometimes you can achieve a better overclock by reducing this and the HT freq multiplier. raising the 'FSB' to get a better match to fast memory (DDR550/DDR600) and a full speed HT. Sometimes is the keyword... not often.

    "Maximum Payload Size:" Looking for an explanation of this one myself. If anyone has a link to a good explanation of this one that'd be great! -- Skip

    The Casey Jones settings

    When the CPU hits a thermal limit (read 'way too hot') it slows down the CPU by the % above to cool it . The higher the % the slower it runs the CPU and so cools it faster but at a loss of performance while the CPU is "throttled" back. This really should NEVER be invoked or you have a serious overheating problem... probably a dead HSF fan or you knocked the HSF off the CPU during your last drunken Karoke party.

    [Musical Interlude Mode On]
    "Oh Casey Jones, Drivin' that train, high on Cocaine... ease back on that throttle 'cause the 958 is on the same track and headed your way..."
    [MI Mode Off]

    Set to 50% or higher IMHO. Think this might have been covered someplace but not finding it this minute. -- Skip

    BIOS Option : Virtualization Technology
    Options : Enabled, Disabled
    Motherboard : Asus P5W DH Deluxe
    Chipset : Intel i975x

    This option ist used to enable/disable the Intel Virtualization technology (also called Vanderpool).

    I don't know, if motherboards for AMD CPUs have a similar option for AMD virtualization (Pacifica).

    Edit:

    I also found this option in the manual of the MSI 975X Platinum PowerUp Edition Motherboard:

    BIOS Option : Virtualization Technology
    Options : Enabled, Disabled
    Description: When enabled, a VMM can utilize the additional hardware capabilities provided by vendor-pool technology.
    Motherboard : MSI 975X Platinum PowerUp Edition
    Chipset : Intel i975x

    vendor-pool is a typo in the manual, because the correct name is vanderpool.

    The right section for this feature in the BOG would be processor.

    Thanks, MrBurns! Will add it to the list ASAP.

    BTW, the typo is hilarious. :mrgreen:

    Hello beloma,

    Thanks for your support! :beer:

    And thanks for the list. I will work on them as soon as I can.

    Incidentally, No-Execute Memory Protect has already been posted here.

    OK, Boss, I'm sorry I did not pay attension to the fact that you already covered the No-Execute Memory Protect setting.

    Thanks so many times for you fast respond, always a pleasure to visit your forum !!!

    It's okay. It's understandable. There are currently about 388 BIOS settings in there! :mrgreen:

    PME

    I thought it stood for "Power Management Event" but seeing it used in front of the "event" casts some doubt on that.

    Ok, I think that we hae to ask to nvidia.....
    this is the official response of DFI to my technical request ...

    Dear Sir:

    To be honest this is not something I can help you with. Please remember that the task of DFI (or any MB maker for that matter) is to assist in any technical problems related to the motherboard. It is not the task of MB makers to educate members of the public as to how motherboard and their functions work. There are hundreds of advanced features in our various BIOSs which do not have explanations, and it would take a large amount of time to research and explane them. Unless there is a direct problem with the USB, please leave the settings at default values. Sorry if this answer is unsatisfactory, but I can not spend large amounts of times educating people.

    What a pud! Minus 1 point for DFI for hiring the jerk.

    Old MSI MS-6119 PCB 1.1 CPU PnP, Award BIOS 4.51PG, BIOS v. p2.9

    I've not seen this option in your guide:

    "Floppy FIFO Control" disabled by default.

    The mobo manual says a vague:
    During enabled, the FDD disk will perform better.

    Keep on!!

    Not yet. We are in the midst of doing something big in the background. Once we cover new BIOS options, we will be sure to post them. Thanks for your support! :thumb:

    LDT Bus Frequency

    Recently I've been trying to assist a guy at OC Wiki in squeezing his socket 939 Athlon 64 3000+ and Jetway mobo into running a bit faster.

    While looking for a way to set the HyperTransport multiplier to 4x we found this in ADVANCED CHIPSET FEATURES > LDT & PCI TIMING SETTINGS:

    • Upstream LDT Bus Width 16 bit
    • Downstream LDT Bus Width 16 bit
    • LDT Bus Frequency Auto
    • PCI1 Master 0 WS Write Enabled
    • PCI2 Master 0 WS Write Enabled
    • PCI1 Post Write Enabled
    • PCI2 Post Write Enabled
    • PCI Delay Transaction Disabled
    • VLink Mode Selection Mode 4

    BIOS Option : LDT Bus Frequency
    Options : 1GHz, 800MHz, 600MHz, 400MHz, 200MHz
    Motherboard : Jetway 939TURBO-G
    Chipset : VIA K8T890 with VT8237 SB

    I believe this to be the equivalent of 5x, 4x, 3x, 2x and 1x HT multiplier settings, respectively.

    With some further experimentation I've confirmed that this IS what this is.

    Another interesting thing in this BOIS is how the "DRAM Clock Frequency" works in the POWER USER SETTINGS menu. Right below the "CPU Clock" is a setting for "DRAM Clock". This function is the equivalent of other BIOSs where you can set the memory frequency (eg. 133, 166, 200) except the option values in this one vary as you change the FSB Clock. This one essentially applies the "divider" to the "CPU Clock" and lists the resulting DRAM frequency that will result. So while the FSB is set at 200 you will see 133, 167 and 200 as options as you go up in FSB these values will go up to what show the resulting memory input frequency. The memory "dividers" available are 0.5000, 0.6626, 0.8292 and 1.0000. So with the FSB set to 250 your options in "DRAM Clock" will be 125MHz, 166MHz, 207MHz, 250MHz and of course "Auto". Auto will select the "divider" with that gives the result closest to 200 but in our example case "Auto" set it to 207 which the memory installed could not support.
