Question about Mach Speed P4MBMS Motherboard

1 Answer

I have a p4mbms motherboard. ...won't boot

I have a p4mbms motherboard. The system won't boot.

Using a POST-PCI-Card, I get an FF error, which translates to "System booting. This means that the BIOS already passed control to the
operation system. If no error flags such as memory size are set ,boot via INT 19 -load system from drive A, then C; display error message if correct boot device not found. Boot system."

Any ideas as how to fix it?
Thank you,

    Does the card show other codes before the FF comes up, they go by
    pretty fast. If you have steady ff from the moment of turning the power
    on and no chance, check the leds on the debug card,

    A. Just a steady FF is displayed. I am noticing that there might not be power to the HD or CD drives as I can't hear them or eject the CD.

    I tried your other suggestions but they did not change any results...still have steady FF.

  • tom_mcbroom Jul 18, 2009

    I should have added that I can't enter the BIOS either.

  • tom_mcbroom Jul 18, 2009

    Using either the built in video, or a PCI video card, I still get the FF error and no apparent HD or CD sounds.

  • tom_mcbroom Jul 18, 2009

    I've tried all the PCI slots now, and have removed the other cards...still get the FF error.

  • tom_mcbroom Jul 18, 2009

    also, the speaker cable was unplugged when I opened the PC...I can't figure out where to plug it in on the motherboard. any ideas?

  • tom_mcbroom Jul 18, 2009

    I don't think I can flash the BIOS since I can't read a disk, or enter the BIOS. If you have any more suggestions I'd love to hear them.

Reseat the memory.

if the machine still doesn't boot.

take out all memory modules out from the machine, now with no memory plug in the power and try starting up, wait 1 minute and turn the power off, now place one of the memory modules back and try starting up again, remember to unplug the power when your connecting or disconnecting parts from the board.

Any change on debug codes how about beeping from machine?

    I see the board also has a integrated video adapter, are you using a agp card? Check both display connectors the machine may be working but its giving the video signal on the wrong source.

  • Ekse Jul 18, 2009

    The motherboard is not booting up at all, you have power but the bios is not running the POST power on self test at all, try another PCI port to make sure you got it on the right one.

    Seems like the bios has a problem or the motherboard / cpu.

    Or you may simply have it on the wrong pci slot.

  • Ekse Jul 18, 2009

    Yes the machine doesn't turn on fully you don't get picture, I understand - Thanks.

  • Ekse Jul 18, 2009

    Try the debug card on all the pci slot to see if it was on the wrong slot, maybe we will get another set of codes.

  • Ekse Jul 18, 2009

    It seems to me that the bios or the board is dead. - its not even trying to boot up, you could try flashing or replaceing the bios on the motherboard, or replace the motherboard. I wouldn't waste too much time on a motherboard.

  • Ekse Jul 18, 2009

    Front panel audio details:

    Same thing on most boards / sound cards.

  • Ekse Jul 18, 2009

    Heres how to do hot flashing with the help of another working motherboard.

  • Ekse Jul 18, 2009

    Oh, That one, Near the front panel connectors, power, reset, etc, if you look closely to the board, you should see text printed on the board, there should be a set of 4 pins (speaker has a connector of 2 wires or a 4 pin connector with only 2 of the pins in use). should read SPEAK. Bottom right corner of the board.

    Heres the user manual, it will be documented there (on the left side of the page link to user manual)

    Its on page 26 of the printed manual (page 29, if we look at the pdf document page count)

  • Ekse Jul 18, 2009

    if you got the speaker connected, you could check if its beeping when you power it on? if it does, how many long and short beeps?

  • Ekse Jul 18, 2009

    Alright, try the hotflashing, if the cpu and memory are OK and tested and the machine doesn't start up even after a fresh flash on the bios, I would replace the mainboard.

My system won't boot but there is power

The things to check when your system will not post are RAM (make sure it is in all the way) Hard Drive (make sure it is properly connected) Your CD/DVD drives (again check connection) and your video connection (if you have onboard graphics, this may not apply, if you have a seperate video card make sure it's properly secured in the PCI slot)

Once you've checked all of these things, if you still have a problem, listen for the beeps that come from your computer's motherboard and remember the order of short and long beeps. Respond with the beep sequence and type of computer you are using.

After installing graphics card my pc restarts several times giving error message ur last boot failed or post interrupted press f1 to continue or del to enter setup im using ati radeon 5770 graphics card...

Hey there,Im pretty sure this is becuase one of 2 reasons:
Possiblity 1:That you have not inserted your video card correctly and some adjusting to its position on your motherboard should help(or even another pci slot if possible)

Possiblity 2:That the Card is not compatible With your system which is unlikley..

I am using mercury 845gvml motherboard but having a problem in vga drivers

To set up vga you have to set the bios setting to the vga platform which you are using like intgated to on board ,pci to pci card and pci-E to pci express card .
Then boot pc and right click on my computer - manage-device manager-display adapter -and see any yellow mark in it .
if their is any mark then update the driver by keeping mother board cd in cd/dvd rom .
delete any non completable driver in it or you can use control panel to do this work .
if you are unable to boot in system then on boot screen press f8 to boot in vga mode or safe mode .and do all work recommended

Try disconnecting all power connectors to the hard drives and CD-Rom drivesin the system. Leave only the motherboard connectors and the video card connector if there is one. Re-seat your RAM and then try. If it boots up, the power supply is being overloaded and it will not power on the PC.

I'm going to assume you supplied the proper 8pin 12v connector besides the necessary 24pin, right? Unplug all cables to any internal peripherals, even data cables. Since you're getting random LED errors, I would remove the video card, open up one of those ancient computers to remove a PCI video card, install it on this board and boot to CMOS. I'd also prepare a Memtest86+ boot diskette and check each memory stick individually (that is if you have a PCI video card output). Keep monitoring/logging those LED errors (to note any type of pattern). The onboard MOLEX power connector, used to provide additional power to the PCI-Express slots when using x16 cards in SLI mode, is located between PCI slot 2 and the board's edge, as a last ditch effort, try powering it up when the Single SLI card is installed. Otherwise, you have either a mal-performing power supply (regardless the total wattage), a funky video card or a DOA motherboard. Always need to carry a known good PCI video card, I use a Matrox Millenium. OH... and take a good slug of your favorite liquor. ZT3000 "Beta tester of "0"s and "1's"
