*DOUBLE POST*
Okay, I was able to do it successfully. Here is how I did it:
1. Open xbtool and click on 'unpack'.
2. Select the BIOS file, (5035.bin, or whatever your BIOS filename is) and click open.
3. xbtool will immediately extract the BIOS into a folder named after the BIOS file itself in the same directory as the BIOS file. Example: Original BIOS file is 5035.bin, so the folder with the extracted BIOS files will also be called 5035.
4. Copy vgapatch.exe into the EXTRACTED BIOS's folder.
5. Open vgapatch.exe and UNCHECK the 'Make Backup' option, and then click patch. If all went well, it should
show the following:
*START PATCHING*
[SEARCH & REPLACE PATCH]
loading file:
xboxkrnl.img
file patched!
...done!
*PATCHING DONE*
6. Delete the vgapatch.exe file, and all you should have left in that directory should be: 2bl.img, remainder.img, & xboxkrnl.img. (Assuming you are using the 5035 BIOS.) NOTE: If there are any other files in here other than what was extracted by xbtool, then xbtool will probably fail when packing, due to the fact that xbtool adds all the files in this directory into the BIOS image.
7. Open xbtool and click on pack, then browse to where the extracted BIOS files are and open up xboxkrnl.img.
8. You will be immediately asked where to save the new bios, and what to name it as. You can save it anywhere, but personally I would just save it to the desktop as 5035.bin.
9. After saving, you will be back at the xbtool screen. Just click quit, and flash your new BIOS.
NOTE: The versions/builds used for this tutorial were the following:
XBtool v1.0.18.b2
X2 5035 BIOS File - x2_5035_vOld_512k.bin
DVADER's VGA Patch v0.1
Hope this short tutorial is helpful.
