Been trying to do it all morning n had no joy! I downloaded the file which was called afudos.exe and renamed it to P5S800VM.ROM. Then when I start my computer up hold alt and f2 and it searches the floppy and say no disk found then it searches the cd and says that P5S800VM.ROM cannot be found :( ARGH! Anyone?

USB Stick?
#2
What's the model number for your motherboard?

I'm guessing Alt+F2 triggers some sort of inbuilt BIOS flashing utility. If your motherboard manufacturer supplies one, get a DOS BIOS flashing utility, make a bootable USB stick with DOS on it, put the BIOS update on the USB too and boot from it. It's the same procedure as booting from a floppy and flashing that way, except you're using a USB pen to do it.

Note if you BIOS update goes wrong it can make your motherboard unusable.

My computer is already being a bit unstable! Keeps just restarting for no apparent reason, GRRRR! I shall try and get that to work on a USB! Ulp

Not if you have dual BIOS feature

1: Download DOS System Files

2: Download HP USB Disk Storage Format Tool

3: Run the HP program once you have installed it.
4: Extract the DOS System Files to a new folder on your desktop.
5: Select the correct Device in the HP software
6: Select the FAT File System
7: Enable Quick Format
8: Enable Create a DOS startup disk >> using the files located at = browse to and select the new folder on your desktop.
9: Hit the Start button - Job done ;)

Just add your firmware file to the root of the USB stick, set it up in the BIOS to boot from other devices/boot from USB/etc and then follow the instructions from your motherboard manufacturer.

Hmmm, Im messing up somewhere - Ive formatted the drive using the programs you said. Then I put the bios file on the usb stick...

Then I was trying to follow the instructions on 2.4 in the manual...

http://dlsvr03.asus.com/pub/ASUS/mb/socket775/P5S800-VM/e2419_p5s800-vm.pdf

But when I boot and choose the USB it goes into MS DOS and it has C:\ on the side and doesnt let me go to G: or any other letter so using the afudos /oP5S800VM.ROM command isnt working?

I bet this is really easy Im just not getting it!
#8
How did you try to get to G: ?

C:\>
C:\>G:
G:\>afudos /oP5S800VM.ROM

Its not working for some reason :'( ARGH! Does it change the drive letter or something?
#10
It may do, just try them all (D: E: F: etc), and use "dir" to list what is there. For example:

C:\>
C:\>G:
G:\>H:
H:\>dir
Volume in drive H is BlahBlah
Directory of H:\
etc
#11
Ah **** its just saying invalid drive for all of them! Damn computers

and providing someone does not update both to a broken bios like some old msi and gigabyte boards used to allow.

surely the usb drive is getting the label c:, they often do..as they dos wont be able to see the ntfx partition on your hdd
you need both the afudos.exe and the bios file as well make sure they are not in a sub directory

Edited By: maddogb on Feb 07, 2011 23:49
#14
As Maddogb says the other drives won't be recognised and so the bios reassigns the usb to letter c:\.
Also why are you renaming afudos.exe to P5S800M.rom? this file is the flash tool you need to download the zip file and extract the .ROM file from it

1. Go to this link
2. Select DOS as the operating system
3. Click where it says "BIOS (20) [BIOS History]"
4. Select one of the download locations and download it
5. Open the zip file and extract the contents onto the usb stick
6. Boot into dos using the usb stick
7. Type afudos /i P5S800M.rom
8. Reboot when finished and remove usb drive

I'm sorry if the step step instructions seem condescending but it just looks like you are doing the wrong thing in the OP.
If you still can't get it to work then use the windows based asus update utility.

Try this program: CPUz - Download on the right panel.

Open up the Mainboard tab and it should give you all the information you need.

You may need to use an additional operator in the string to force the BIOS flash. Although I don't recommend it :3

What seems to be the issue that is making you want to flash the BIOS, maybe there is an alternative solution that is a lot safer?
#21
My computer is just restarting itself without warning sometimes and a few blue screens. Also I have two 1gb RAM in the drive and it showing as a total of 1.5 so I figured the motherboard bios may be out of date?

Your motherboard: P5S800-VM - appears to have an onboard graphics chip which will share the memory of the system. So 2GB of standard memory will = 1.5GB as 512MB is being used as VRAM (graphics/video memory). You should be able to modify this in the BIOS, 128MB/256MB/512MB/etc.

Blue screens and restarting itself does sound odd though. Although I have rarely found these issues relate to the BIOS. More than likely they are heat related, memory related or you could simply need a clean install of the operating system.

Have you checked inside the case for dust etc?

Edited By: PhearFactor on Feb 08, 2011 19:54
#23
Yeah Ive just reinstalled windows so it should be fine, was still getting the restarting, Ive had the case open and it doesnt look overly dusty - Is it worth changing the RAM settings or is it fine how it is? Its not running slow or anything
#24
It should be fine how it is. Perhaps you should have a look in the Event Viewer to see if Windows has recorded any data before the crashes/BSODs that may help determine what the problem is.

Also if you open up CPUz again, the program you installed earlier. Can you post the details on the first tab that opens (CPU). It would be easiest if you could print screen and then post the picture on here. Hopefully you know how to do this?

Sure, think this link should work...

That looks normal. Next thing would be to check the temperatures and then after that to check the memory.

Speedfan should hopefully work with that motherboard: Download here
Reply here with the temperatures in case you are unsure whether the readings are good or bad.

For Memory testing instructions/software, best bet is to start here

Okay, not sure if Im giving you the right info here but here it goes!

GPU - 42C
SYSTEM 35C
CPU 68C
AUX 53C
HD0 32C
HD1 37C
CORE 42C
AMBIENT 0C

It has a flame beside the CPU and AUX, Id guess thats bad...

Will have a go at memtest now!
#28
That CPU temp looks high to me. You 100% sure that processor fan is dust free? :3
#29
Yeah, Ive had the front cover off to install the ram recently n it looked fine, hmmm will give it a good dusting and try it again!!!
#30
Might want to reapply the thermal paste between CPU and heatsink. Make sure heatsink is clamped on tight too. Mine is a right pain to get on and it's possible to not properly attach it to the motherboard if you're in a rush (have done it myself!)
1 Like #31
Just make sure it is mounted correctly also (the heatsink and fan). I think that processor should idle at less than 50c, so almost 20c higher doesn't look good. I would look in to getting that temperature down before doing anything else.

Also you could try renaming the .ROM file to P5S800-VM this may help

If not is the board an OEM for another manufacturers computer such as Medion or Packard Bell?

if you use the /nr switch it won't check the rom id but like you say not recommended as it could brick your bios.

bootable cd version of the bios here

Sorry didn't know the conversation had progressed to bug finding :|

I think it is safe to say that his Prescott is overheating. If it is at 70c when just browsing the tinternet then it does sound a little toasty. It is no wonder it keeps crashing as more pressure is piled upon it, poor little thing :(

I am not 100% sure on what the max temp. is for that processor, but surely between 70-80c - would explain the random restarts if it is cutting off to save itself from burning out.

Hehe, nothing better than a bit of troubleshooting.

Just did that memtest and I passed! WOO!

I guess it is just the fan, Just gave it a once over with the duster and its at a mean of 65C so nothing has changed! Will have to look into getting it to work better or just wait for it to blow up as Ivechanged the windows settings to disalow it from restarting when there is a problem!! Think Ill give the whole updating the bios a miss as it doesnt seem to be needed if the memtest is working okay...

One quick question about the ram though, Im pretty sure I have a graphics card that is different to the onboard one, should the RAM still be going into the onboard graphics chip? Im defiantly running my graphics through a NVIDIA GeForce 6200 card.

Now there's a good question. Just reading the manual now to see if there is an option to disable this.

no option in the bios to disable the agp shared memory but you can lower it to 32mb and set your primary adapter to agp. You could also disable your shared memory size. Don't think this will make much difference to your system though.


Edited By: trog0 on Feb 08, 2011 22:24: errors, ok? We all make them
#36
Thanks ill give it a go tomorrow! And put some ice in my computer or something to stop the fan overheating! Thanks for help tonight everyone!
#37
the temp is not overly excessive for a prescott but if its that with the side off or idling it will go much higher if the case isn't very well designed for airflow, or as stated with a lot of dust in the wrong place.
with the side off and the machine off you should see the metal heatsinks under the cpu fan quite clearly, if not get a natural paintbrush and vac in there avoiding the board components.

oh and give phear a load of thanks, flashing a bios on a overheating cpu is usually a major disaster.
