Flashing X61T Windows 10 64 to Middleton ROM

[Tito_V]

I have scanned all these answers without finding out how to flash my X61T rom with the Middleton version. The issue I had is that I had already installed Windows 10 64 bit, and the Middleton ROM Flasher will only work with 32 bit installs. The X61T is a spare that I'm experimenting with, so I just made a wild guess and it seems to have worked.

I made my boot USB following the instructions on this forum:

- Found an old 1GB USB Thumb Drive
- Downloaded the win98boot files and unzipped them into a folder
- Installed and ran the HP USB Disk Storage Format Tool in admin mode.
- Formatted USB Flash Drive in FAT[16] as a Boot Drive, pointing it to the folder with the win98boot files.
- Downloaded Middleton's ISO file. (There are a variety for different machines) http://www.thinkwiki.org/wiki/Middleton's_BIOS
- Opened Middleton's ISO file using an archive extractor and just copied the contents of the folder I wanted (not the disk images, in my case) over to the root directory of my newly formatted USB BOOT drive.

HERE'S WHERE WHAT I DID DIFFERENTLY FROM THE SOLUTIONS IN THIS FORUM
- I downloaded phlash16 v1.7.0.21 from https://www.wimsbios.com/phoenixflasher.jsp. This DOS version is essential, since we are working off a DOS boot.
- I copied PHLASH16.EXE to the root directory of the USB BOOT drive
- I opened FLASH.BAT from the USB root directory and changed it as follows:

Code: Select all

@echo off
echo Updating BIOS. Please wait...
PLASH16 $01B6200.FL1    [This starts Phlash16 for Dos and runs the ROM image file, in my case $01B6200.FL1]
echo BIOS flash completed. Reboot your machine now.
pause

- Changed my ROM startup to USB Drive

- Restarted. Boots into DOS.
- At the Command Prompt typed "Flash" and enter to run the batch file.
- The system ran the ROM update process
- Let it run the process.
- It will restart, press F1 to enter BIOS. Check version number, if matches to Middleton's BIOS version then you successfully flashed to the modified BIOS.

I make no guarantees. Use this strategy at your own risk. Hope it saves someone the hours of trolling through forums finding hints on possible solutions.

My thanks to all those who wrote about this process, including ScaryRaebbit, ThinkWiki, Ahmed Hossan https://www.bios-mods.com/forum/Thread- ... OS-PHOENIX, and even though I didn't have time to try his method, pcapex.

I still haven't gotten my touchscreen working or the buttons on the tablet, but I continue working on it.

Nice post. I still install Windows XP when I flash the Middleton Bios and then format for something else, but its nice to know one doesn't have too.

Middleton's BIOS can be installed using a self-booting CD from the ISO that's included in the download...
For an X61 you need either an external CD-drive or an Ultrabase.
