Hi everyone,

Has someone succeeded to flash Middleton BIOS using a USB key ? I'm using Linux and tried the two following commands (this was the most promising lead after hours of googling... sorry I'm a noob) :
I can't boot : I get the "non-system disk" error

Any hint ? Thanks ! (currently don't have any Windows box here at home)

P.S. : I'm trying to bring new life to honeypie, my X61s... Was trying to flash Middleton before putting a SSD drive.

Middleton has a bootable .iso file in each download.
Use an external CD-burner/player to load the BIOS.

Check the USB is bootable.
sudo fdisk /dev/sdX
click p to view partition table and there should be an * in the boot column.

Other options:

OPTION 1
1. dd this image to your usb http://jesseo.com/thinkpads/dosboot.img
2. extract files from iso
3. copy necessary files to usb
4. boot from usb

I made dosboot.img as follows:
1. format usb in windows with Rufus using its default settings for dos image
2. dd if=/dev/sdX of=dosboot.img bs=512 count=30000
