Asus P4P800-E Deluxe PAT question

post #1 of 4
Thread Starter 
Does anyone know what is the requirement for running the pat technology on p4p800 e deluxe. like if it would work with a 533fsb bus or does it need to be 800fsb only to work right.

You can apply the BigToe Bios modification to fool the computer into thinking that you are running the 533 bootstrap.

Any 533MHz fsb P4 on the P4P800 E Deluxe will automatically run PAT (Performance Acceleration Technology) and the 800MHz fsb P4 will also but only on the ASUS model. ASUS has built this functionality into their board.

However, should you take the FSB 1MHz past 200 you immediately disable PAT. BigToe's Bios Mod allows you to flash a P4P8X bios for the boot block, then flash a P4P800 E Deluxe bios (without the boot block). This effectively fools the computer into thinking you are running the 533MHz bootstrap and enabled PAT. You can then overclock past 200MHz with the PAT enabled.

I have performed this modification and it does work. Be advised it will NOT work on a P4P800 SE board.

Props for this Bios Modification should go to BigToe

Materials:

Two floppy disks
10-20 Minutes

Procedure:

Well, to start, get one floppy disk ready. Make it into a DOS Boot-Disk, and write-protect it. Put it aside.

Now, get the second floppy, and get AFUDOS 1.16 (comes on the ASUS P4P800 CD, it is also attached to this thread). Also, get a BIOS file for the P4P8X, and a BETA (important) BIOS file for the board you are using (in this case, a P4P800). Put all of the files on the floppy disk (AFUDOS, P4P8X BIOS, and the P4P800 BIOS)...

Reboot your machine, and go into your BIOS. Set it to defaults, and then set your overclocking settings to:

CPU Frequency [133Mhz]
DRAM Frequency [266Mhz]

And leave everything else default.

Now, boot off of your DOS Boot-Disk, and then switch to your second disk (BIOS files and AFUDOS).

Now, you have to flash your board to the P4P8X... In this case, the P4P8X BIOS will be named "p4p8x.AMI"... After you switch from the DOS Boot-Disk to the BIOS disk, type the following (change the filenames respectively):

afudos /iP4P8X.AMI /n /pbnc

Remember the '/i' before the BIOS filename, and let it flash...

Now, reboot your machine, and if all went well, you now have fooled your board into being a P4P8X...

After you are done, go back into the BIOS, and change your overclocking settings the way they were before you flashed BIOS (as follows):

CPU Frequency [133Mhz]
DRAM Frequency [266Mhz]

Now, reboot again, and boot off of the DOS Boot-Disk. Switch disks again, and then flash the BIOS file back to the P4P800 BIOS (in this case, 1020.002) with the following command line:

afudos /i1020.002 /n

Notice that the /pbnc is gone from the command line. This tells AFUDOS not to flash over the boot-strap of your BIOS.

Go back into the BIOS, and set things the way you like... Now check to see if PAT is enabled in Everest.

If all went well, you now have patched up your Springdale chipset (i865PE) into a Canterwood chipset (i875P) in effectiveness...

Final Notes:
Your board is now PAT enabled, and not only partially... It should perform a little better than before... Your overclock won't be as high as before, but thats a small sacrifice... Your memory bandwith will be higher than before... REMEMBER, if you flash with a release BIOS, then you will lose PAT capability... Also, using dividers different than 1:1 won't work as well/at all...

Needed:

AFUDOS 1.16 b2
P4P8X BIOS
P4P800 BIOS
