Recently I managed to flash an ASUS Maximus Formula x38 to a Rampage Formula x48. What this does is aid in FSB and Memory overclocking. It also expanded the CPU compatibility library. The whole process is quite easy and if you have flashed through DOS in the past even simpler. For those that haven't used a DOS tool I'm going to make this easy. just follow the commands. To accomplish this you're going to need to make a bootable USB and add some files to it which I will include in this post. The beauty of the bootable USB is that you can hve more than one program on it for flashing boards and cards it'll work for any of them. You just need the right commands to start the .exe of your choice. The one we're going to be using is an engineering version of AFUDOS. This one is the key to changing the board ID.
First you'll need to download and extract this folder.

Now, to make a bootable usb
Extract all of the files
Open up the Windows 98 Archive you downloaded and extract it to a folder.
Open up the HP Format tool. Make sure you select the drive you want to make bootable, and that FAT32 is checked.
Check the "Create DOS Startup Disk box, and link it to your extracted windows 98 folder.
Format the drive. It should be bootable now.
Prep USB for flashing
Copy the AFU236U application and 0803.ROM bios file to the USB. Just a note on BIOS version. Anything newer than this version will not work.
Plug in the USB
Start the board you are flashing and go to the bios. Select optimixed defaults and set the HDD priority to the USB that you are using.
Restart.
Flashing the board.
IF all goes right you should be greeted with a DOS command prompt, type the following to flash to the Rampage Bios
Note the "/i" that comes before the bios filename, this is required for any flash with AFUDOS. And note the extension on the bios file in use, you'll need to use this too.
That's it just restart the PC when prompted. I did have a slight scare here since after the re-boot , all I had was a black screen. I left it for a couple minutes like that then reset and it booted to the new ROG logo.
Next up is a simple pencil mod that fixed the Vdrop/Vdroop I was getting with this board. Before mod setting 1.4v would give me about 1.34v under load. After it was 1.4v to 1.388 drastic improvement and very simple all you need is a pencil. Softer ones work better but I did this with just your everyday school pencil.
1. locate the EPU chip (between CPU socket and RAM slots)
2. look for the first resistor, top right corner, adjacent to the CPU socket (see pic)
3. use 2B or 4B pencil (soft lead are better), do 2 strokes pencil in the resistor. Until it gets dark. Make sure you don't touch any other resistors beside it.
