post #1 of 3
Thread Starter 
OK so i been stuck with the version 1003 for p5n32 e sli plus for like weeks now. pissed me off the thing cant OC for ****

3 week ago i went mental on how to make a boot able USB drive. and believe me it was so hard to find some details post for a dumb and dumber like me. Dos twitching was like !!!!

However i ran in to this post like 1 hours ago and finally... my system is back on 3.6 again and no Vcore lock whhheeee~~~!!! .

This is a thread by Moderator LOGAN from DFI club.
How to Make a USB Pen Drive Bootable

The Guide is based on creating/getting a USB Pen Drive to boot on the DFI NF4 series mobo. The second part shows how to flash your bios from the pen drive.

Part 1
1. The easiest way to do this is with a floppy drive, if you don't have one, there is an alternative method at the bottom of the guide.
2. For XP users insert a blank floppy disc into the drive, open My Computer and right click on your floppy drive and choose "Format" from the popup.
3. Make sure the 'create a bootable system disk' option is checked. This will add the system files needed by the USB drive from the floppy. Click 'OK' to format the disk.



4. HP are constantly changing this utility, and as such the version you download might differ from the one in the guide HP Drive Key Boot Utility V2.1.8. Its intended obviously for HP usb drives but works fine with most other usb drives.
5. Plug in your USB drive and run the HP USB disk storage tool.
6. Ensure that the tool has found the correct drive in the "Device" box. Change the "File System" to "FAT". Check the "Create a DOS startup disk" option, and in the "using DOS system files located at:" window, enter "A:\\" to point the program to your floppy disk or browse to it. Now click 'Start'. The program will create the necessary boot files on the USB drive.



7. Reboot your pc, when you see the post screen hit the Escape key, this will bring up a Boot Menu screen. Choose your USB drive from the list and hit Enter.

8. If all has went well you should have rebooted to the C:\\ prompt. Congratulations you have just made a Bootable USB pen drive.

Alternative Method for users with no Floppy drives For users without a floppy drive download the XP Custom Boot disc . This is a .exe file that contains all of the system files that you will need. Extract the files to a folder using Winimage etc. In Step 6. Point the HP USB utility to the folder containing the XP Custom Boot files. (instead of choosing A: like in the image chose the folder you extract the file to)

Notes: Some USB pen drives do NOT work, mp3 type pen drives don't work or at least the ones i have tried do not, only a dedicated pen drive should be used, it should also be 256mb to 2GB size, below or above does not work either. The Corsair Flash Voyager USB Pen Drive work perfect.

How to flash your bios from USB pen


WARNING!!!!! Do Not Flash a Bios While Overclocked, always set Stock Settings before Flashing any bios.

If you have followed the guide above and have a working bootable USB pen drive then you can easily use it for say, flashing your bios....here's how.

1. Download the correct bios for your motherboard from www.DFI.com
2. Next extract your downloaded DFI Bios to a folder using WinRAR or similar, Copy the xxxxxxx.BIN, the AUTOEXEC.BAT file and AWDFLASH.EXE utility to your new Bootable USB drive.
3. Right click the AUTOEXEC.BAT file and choose Edit, add the following lines to the AUTOEXEC.BAT file, or open the AUTOEXEC.BAT file with any text editor (Notepad) and Edit/Add the the lines below.

@echo off
cls

C:\\AWDFLASH xxxxxxx.BIN /cks/sn/py/cc/cd/cp/ld/qi/WB/ch
echo "The version of BIOS was inaccurate,"
echo "Please remove the floppy, download the right one and re-flash."
@ECHO OFF



4. Where xxxxxxx.BIN = the name of your bios.Bin file. The prompt needs changed to C:\\ from A:\\ as above.
5. Save the AUTOEXEC.BAT and Close it.
6. Make sure your Bootable USB drive is inserted and Reboot your Pc.
7. Hit Escape key when the post screen comes up to enter the Boot Menu Screen.
8. Select your Bootable USB pen drive from options listed and hit Enter. The bios should flash automatically. Follow instructions when its finished flashing.

Good stuff, but why do you need a bootable USB drive, you have a ASUS board and ASUS EZ Flash 2 so do like this, it´s from ASUS Forum. Have done it many times and it works every time

EZ Flash 2 – the best, the safest and the most convenient way to update BIOS.


Revised January 7, 2008.



Updating BIOS is serious business!
Every precaution should therefore be taken to prevent that anything goes wrong. Above all: DO NOT USE ASUS UPDATE!!! AFUDOS is the only good alternative to EZ Flash 2.





EZ Flash 2 is a built-in function of BIOS. It is the safest way to update BIOS, because one is not dependent on the Operating System, any application, internet connection, firewall settings, antivirus or anything else that can put the vital BIOS update at risk.



On a new build, BIOS can be updated to the latest version before installation of the OS, which may possibly make the installation go smoother and safer.



Note: All what's said below about loading BIOS defaults also applies to the other BIOS update methods (ASUS Update and AFUDOS)!



The PC must never be overclocked during the BIOS update! Always load and save BIOS defaults before and after a BIOS update (press <F5>). By loading and saving BIOS defaults before the update, CPU frequency, memory frequency and voltages are set to default (Auto).
Memory timings are set to SPD values which ensures that a PC with high performance memory that need a higher voltage than 1.8V is able to boot on the standard DDR2 Memory Voltage of 1.8V. Save the default settings (press <F10>) before starting the update.



When these instructions are carefully followed, there will be no need for a CLRTC.


Preparation:


Document all your preferred BIOS settings (i.e. the settings you have changed from the default setting).
Download the BIOS file, which normally is compressed (zipped).
Unzip the BIOS file to a FAT/FAT32 formatted USB Flash Disk with only one partition (or to a Floppy Disk or IDE CD-ROM). If the unzipped BIOS file is named like e.g. 'P5B-ASUS-Deluxe-1101.ROM', you can rename it to 'P5BD1101.ROM'. Otherwise a truncated name will appear as 'P5B-AS~1.ROM' due to a limitation to max 8 characters in the filename (8.3).
Updade:

Reboot.
Press (tap) <DEL> during POST (Power-On Self Test) to enter BIOS Setup.
Load BIOS Defaults (press <F5>).
Insert the USB Flash Disk containing the BIOS file P5BDxxxx.ROM. (Note that the USB Flash Disk has to be inserted before boot to enter BIOS, otherwise it won't be detected).
Save and Exit <F10>. (BIOS will now restart).
During BIOS restart, press <DEL> to enter BIOS Setup again.
Under Tools menu, select ASUS EZ Flash 2. It may take 20 seconds for the drives to show up. Select a drive in the left pane <Tab>. Use <Up> and <Down> arrows and <Enter> to select a drive. If you don't see the BIOS file in the right pane, check the other drives. Note that the drive letters are not the same here as in Windows and that no HDD's are shown here.
Select the BIOS file (e.g. P5BD1101.ROM) and press <Enter> to start flashing. Supervise the update, which includes the following stages: Erasing - Flashing (writing) - Verification. BIOS will automatically restart when the update is ready.
Disconnect the USB Flash Disk before/during the restart.
Perform a C.P.R. (CPU Parameter Recall) which resets the chipset. Power down, remove power cord from the PSU for 2 minutes and then power up.
Enter BIOS and load BIOS Defaults <F5> again.
Reinsert your preferred BIOS settings - if you are using AHCI or RAID mode, don't forget to set 'Configure SATA as' to [AHCI / RAID]. Also remember the settings for the JMicron Controller, Audio and Memory Voltage. Check also that the Boot Device Priority is ok.
Save and Exit <F10> (automatic restart).
Press <DEL> to enter BIOS Setup and make a final check that all BIOS settings are ok. Save any changes.

In case of a new build:


When BIOS is updated to the latest version, and prior to the installation of the operating system, run Memtest86+ (v2.01 or later) for a few hours to check that the memory test doesn't report any errors.
There are precompiled bootable downloads for Floppy Disk and CD-ROM (ISO).

@GHOSTLEADER:

Yes i know ez flash2 is good but it can only upgrade not downgrade. So USB boot is the only method that can get you around downgrade bios.

"In case of bios downgrade 100% exflash2 will report incompatible rom"

So this is the purpose of USB boot.
