Cannot update P5K BIOS

I’m having trouble updating the BIOS on my P5K.

I purchased a Q9550 CPU. My motherboard is an ASUS P5K running BIOS version 0603. There are 5 later releases, all of which were updates for new CPUs, so I suspect I will need these updates.

I have tried 1 approaches:

First I followed the procedure on this page titled Using ASUS EZ Flash to Update BIOS.
http://support.asus.com/technicaldocuments/technicaldocuments.aspx?root=198&SLanguage=en-us

I get into the stated utility and wait for it to read the directory on A. I then tab over and click on the .ROM file name. It returns an error “error occurred when reading the file”.

---------------------------------

Next, from the same ASUS support page I downloaded the AFLASH.EXE file, unzipped it, and placed it on a bootable floppy. Then I copied the .ROM file to another floppy (insufficient space on the first floppy).

Then I boot from the floppy and get an A:/ prompt. I run aflash and get an error "can't find System BIOS' Hook."

---------------------------------

Any idea how to overcome this, or an alternate procedure?

  1. well, this just gets better and better.

    I found a program on the CD that came with the motherboard. It allowed me to update the BIOS. The screen instructions asked me to reboot which I did.

    On reboot the options for F1 (enter setup) and F2 (load defaults and boot). I took option 2.

    It booted and seemed to be ok. I powered down so I could perform a col reboot, and I intended to Alt/F2 so I could view the current BIOS in their flash program.

    Now I cannot power up the system. I see a green LED on the mobo but pressing the power button has no results.

    What now?

    The pisser is that I just bought this new Q9550 and had already opened it as I was preparing to install it today. Newegg has a "exchange only" policy. If I have to buy a new mobo, can I buy one sans-CPU so that at least the cost of the new CPU is not lost?
  2. Power off the PSU (or disconnect it) for a couple minutes and power it on. Then try to power up the PC. If that doesn't work, then reset the CMOS.
  3. Did that already.

    I will go google "reset the CMOS" but if you can direct me, please do. Thanks.
  4. ok, just found this. is this the correct procedure?

    ok, this is really awful. I found a diagram of the board.

    Just above the clrtc jumper there is a block titled "panel" where a bunch of little plugs are attached. To even see the jumper, much less grab it, I had to pull a plug off of "panel", and along with that came others. Do those go back on in any particular order?
  5. All you had to do is follow the procedure in your manual; you didn't have to remove any wires. Put them back the way they were; the info is in your manual. You probably shouldn't try to upgrade the CPU if you don't know about clearing the CMOS.

    That may be a valid point and I'll consider it seriously, and will very like haul the system to a shop for that. For the moment though, I need to decide if it is necessary to order a new BIOS chip, or if clearing CMOS will get me past the immediate problem.

    Unfortunately, due to the proximity of the wires to the jumper, pulling a couple wires was not avoidable. VERY crowded. I even pulled the drive bay out to make room.

    With that said, the manual states that the system panel connector (20-8-pin PANEL) is used to connect these:
    - system power
    - hard disk drive activity LED
    - system warnihng speaker
    - ATX power button/soft-off button
    - reset button

    I also see a plug labeled ground.

    Am I safe to generally plug them in to that connector, or is there likely defined positions on the plug where they go?
  7. Switches will work either way. LEDs will not work if plugged incorrectly. Reverse them if they don't light up.
  8. ok, not successful. I'll just take it to the shop. thanks.
  9. what is odd, btw, is that it looked like it worked. when I plugged it in and hit the power switch the drives began to run. Then it all just powered down again. ANy thoughts?
  10. If all wires are properly connected, then you have another issue, but it's difficult to test a system without spare parts. It could be the PSU, the video card, etc.
  11. You've been very kind to help. Thank you.
