After several attempts and a lot of frustration with Nero, and older tutorials I came across this easy fix.
It uses the built in CD burning in Windows XP. This BIOS is for a x2 2.2lite +
If you have a different chip that requires a different size BIOS, then change the BIOS file size accordingly.

What you need:
* Windows XP- Home or Pro
* 1MB BIOS file (renamed to bios.bin) I used the x24979.06
* 100MB Dummy file
* CD-RW ( I used an Imation 4x speed)
* CD burner (obviously) :)


* This is a tutorial for use after you have installed a preflashed modchip that has a Cromwell BIOS on it, and is when you boot you're Xbox,
is asking for "BIOS update CD". *

1. Make a folder on your desktop (name it Bios) and put your 1MB BIOS file in there, and rename it bios.bin.
2. Next make a 100MB dummy file- this is what I used. http://mynikko.com/dummy/
This program is free and very simple to use and understand.
Enter 100MB for the file size.
I checked the "random file content" box.
It will create the file in C:\dump.txt
3. Next, copy that "dump.txt" file into the folder you created on the desktop where your bios.bin file is located.
4. Now you should have your 1MB bios.bin file and the 100MB dump.txt file in the folder on your desktop.
Almost there...
Make sure you have a CDRW ready to go in your CD burner drive. (preferable new unused media)
5. Now, open that folder, select both files CTRL +A, right click, go down to "Send to" and select D: or E: whatever your
drive letter is for your CD burner.
6. Windows XP will now notify you that you have file ready to be written to CD.
7. Open that window, if will show your 2 files that are ready to be written.
Select "Write these files to Cd" in the top left pane.
8. XP will burn the files to the cd
Thats It! No messing with all those stupid Nero settings anymore.
The CD worked the first time in my Xbox. You may have to try the CD a few times, depending on what type of DVD drive your Xbox uses.

Note: I haven't tried this method yet with any other files, but chances are this will work with burning other install CD's (EvoX installer, etc.)???
