Re: bios update

Make sure your bios is an eprom. people download bios upgrades only to find their bios is not a flash bios. that is it doesn't have the infrared source to physically "flash" the chip.

you must plug in your pc with ups

1st thing you'll need to do is go to the motherboard manufacturer's website & download the new BIOS file & the flashing program. These 2 files will have to be copied to a bootable floppy, then you'll have to boot off it & do the update from DOS. The motherboard website should have a detailed explanation on how to perform a flash...print out the instructions & follow them exactly & you should have no problem

File P4P800SE.ROM not found

Sounds like you're trying to flash the bios..

Using ASUS EZ Flash to update the BIOS: The ASUS EZ Flash feature allows you to easily update the BIOS without having to go through the long process of booting from a diskette and using a DOS-based utility. The EZ Flash is built-in the BIOS firmware so it is accessible by simply pressing <Alt + F2> during the Power-On Self Tests (POST). To update the BIOS using ASUS EZ Flash: 1. Visit the ASUS website ( to download the latest BIOS file for your motherboard and rename the downloaded file as P4P800SE.ROM. Save the BIOS file to a floppy disk. 2. Reboot the system. 3. To launch EZ Flash, press <Alt+F2> during POST

Hope this helps

Bios update problems P4S800-MX

An .exe file isn't a .rom file. You downloaded the flash program (the program used to flash new data to the ROM), you didn't download the flash data. Look on the site again, or look to see if there's another file - P4S800MX.ROM - to extract.

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 :-)
