Re: corrupt bios

ROM is the key word here. for some reason, your bios flasher believes your CMOS memory is ROM: read-only memory! I do not know why. if you haven't already, try resetting CMOS (using jumper) and trying again.

Unknown processor - update BIOS - press F1 to continue

Hello jssingh

if the system boots but gives unknown processor message then it means you have to do what is says,that is to update your bios.

go to asus web site.

go to services ---> support ----> download

on the left hand side at the top enter your motherboard model number "P5SD2-VM".
under it choose Bios

the main board model will be listed and you be asked to choose an operating system. (choose any operating system. bios is independant of operating system)

look at the list all available bios versions. download the latest. it usually comes with the upgrade utility as well but you can download the utility anyway

you cal also try this link for your bios download

format a floppy disk and make it bootabel (you can also use a usb flash drive or even a cd)
copy the files to it. start the computer and boot from it.
at command prompt type the afudos command and the new bios version.
follow the prompt. it will update the bios.

good luck. hope this has helped you.

when you boot from the floppy at the command prompt you need to type in the utility name "Afudos" follows by the new bios name.

you can also do this using a bootable flash drive.

I always have failure to boot and have beep sounds. Already installed asus update v6.10.02, still shows overclocking failed on start up and requests to configure BIOS. My system includes: inno3D-FX5500...

1-Does your computer show any sign of response after power button press?
2-Is your power cable properly connected and have main power switched on both your power supply unit and the wall plug?
3-Is the 20/24-pin ATX power connector has been connected between your motherboard and power supply?
4-Can The standby power LED (Green blue) light up continuously after the mains power is connected? (Note: Both flashing and off are no good here)

Fix 1

(1) Isolate The power going into your system ( i.e. connect your system to the wall plug directly, without sharing the power with any other devices via power extension cable.)
(2) Check if the power supply and power cable functions correctly, and have the input of your power supply set to the correct position (either 100/110V or 220/240V, depending on your country)
(3) Please try replacing your power supply.

Fix 2

1. No POST

1.1 Please clear CMOS to have a try (refer to motherboard manual for details)

1.2 If the problem still persists, please contact your retailer for a check

2. There is error message during POST: BIOS ROM checksum error. Detecting floppy drive A media... Insert system disk and press enter

2.1 If the support CD supplied with motherboard is available

2.1.1 Please restart system and put support CD into optical drive, then the system will recover BIOS automatically using CrashFree utility

2.2 If the support CD supplied with motherboard is not available

2.2.1 Prepare a formated floppy disk, then unzip the BIOS file downloaded from ASUS website into the floppy disk.

2.2.2 Please restart system and insert the floppy disk into floppy drive, then the system will recover BIOS automatically using CrashFree utility
2.3 If it is not helpful after the troubleshooting as the steps 2.1 or 2.2, please clear CMOS( referring to the manual introduction)

Fix 3

Please try the latest BIOS. I recommend you to use AFUDOS to update BIOS. You need to unzip it to get the ROM file.

You should use the command as follows:

AFUDOS /i[biosname]

or, afudos /i A:\BIOSNAME.rom(if the BIOS file is in the floppy disk)

You can store your BIOS into a floppy disk or a hard disk with FAT format. Then, you will be able to use AFUDOS to access the BIOS ROM file.

If it is not convenient for you to use DOS and AFUDOS, you can try to use EZ Flash. You can save the BIOS file into a flash disk then boot the system and enter BIOS, then you can update your BIOS by EZ Flash which is in the BIOS Tools page. Please load the default settings in BIOS after you have succeeded updating BIOS.

If you need more help come back.Post / thumbs / testimonial are welcome!

CMOS BATTERY LOW CMOS SETTINGS WRONG CMOS MEMORY SIZE WRONG. I was getting that error, and then i went and brought a brand new battery, the CR 2032, the same that came after...After i booted it up, went...

  1. here are the instructions to Flash Your BIOS -
don't forget to read the information that's included and related to flashing in your motherboard's manual. Yes, dig that manual out (or if you can't find it then download it from the manufacturer's website; it's usually available) and read it!
Four of the most common flashers are: AWDFLASH, AMIFLASH, UNIFLASH and AFUDOS (only for ASUS boards). Out of these the UNIFLASH (get it here) is the universal flasher that can usually flash every BIOS; it has awesome compatibility capabilities. Keep in mind that BIOS flashing can be (and is) dangerous, because in the case of a bad flash the data ends up corrupted and your computer won't POST anymore. So I'm recommending wholeheartedly that you use the BIOS flasher that's explained in the manual and provided by the manufacturer of your board. Read the manual, do your research and when you're ready, then and only then proceed to follow the instructions.
After you get your flasher you need the latest BIOS flash file. First find out your motherboard manufacturer's name and your board's exact name and specifications. Visit your manufacturer's website and download the latest non-beta version (betas can be risky and I don't suggest you experiment if you can't fix it if a bad flash happens; we'll discuss that a bit later). These files usually have ".ROM" or ".BIN" extensions. Later on I'm going to call the "latest BIOS file" "newbios.bin."
I'm going to give you examples of how to use UNIFLASH, AWDFLASH, AMIFLASH and AFUDOS. Read them strictly as examples and do not proceed to flash your latest BIOS version before you understand what each option gives and how to use these flashers.
Flashing with UNIFLASH:
A:uniflash.exe newbios.bin
Flashing with AWDFLASH:
A:awdflash.exe newbios.bin /py /sn /cc
Flashing with AMIFLASH:
A:amiflash.exe newbios.bin /A+ /-B /-C /-D /E /-G /I /L /N /R /V
Flashing with AFUDOS:
A:afudos.exe /inewbios.bin
Even though the above commands do work it's always crucial that you read what every command does and understand them. First of all, once you're booted into MS-DOS, execute the flashers without commands and options. Just use a simple "awdflash.exe" or "amiflash.exe"-- then a help screen (which explains all of the available commands and options) will appear. Read that thoroughly before proceeding and follow the instructions.
As a side note, UNIFLASH has a UI (user interface) so it definitely helps beginners. Execute the "uniflash.exe" and the UI will appear and guide you through.

Problem with my Asus p5pe-vm motherbord.When i start it,the message CPU uCode loading error appears.What to do...HELPPPPPPP

If your over clocking your CPU settings reset to default. See if you still get the error. If you still get the error than update your bios. There are a couple of way to do this. You can use the software on your Asus CD or you can down load the latest BIOS-Utilities, Afudos BIOS update tool V2.36. Than download the bios file, P5PE-VM BIOS 1501.
Using built-in EZ Flash to flash BIOS Please be informed that not all motherboards support EZ Flash,
please use DOS flash utility to update BIOS if your motherboard does not support EZ Flash;

Happy holidays!

I am unable to update bios of my p5rd1vm mboard it update every time but nothing happen

You need to download AFUDOS and the new ROM for the BIOS (both can be gotten from the Asus website). It is easiest with a floppy disk but since I couldn't find any store that carried them I created a bootable CD (search around at for the different ways to do this) and added AFUDOS and the ROM to it. Once this was burned, I rebooted and booted from the CD and was able to flash the BIOS using the instructions that came with AFUDOS. Of course this is only required if you can't get the EZ Flash utility to work which I could not.

BIOS 1004 cpu not support

I got it :-)

Damn Asus , it was a hard session ;-)

1. Make an ISO from your original Asus CD denn insert (with isobuster or something) the Bios Firmware 1004 in the main Dir name the file M2N-MX.ROM

2.Burn a Second disc with the 0804 Bios ROM also rename the 0804 Rom to M2N-MX.ROM

3. Go to EZ FLASH with ALT + F2 and then insert the 1004 CD wait till Erasing is ready Then Turn OFF your PC :-) so you crashed the bios thats what you need to run the embeded CrashFRee Tool

4 After you turn your PC on insert the 0804 CD then it flashes the this Rom and we are Happy :-)

mfg Eddi Hope this helps someone
