Introduction

This guide shows how to update the latest UEFI for your motherboard. You will need bootable UEFI update CD image and USB flash drive.

Format USB drive

Create partition and format it to FAT-32. Check dmesg to find out the USB flash drive device node (/dev/sdb in this guide).

root # cfdisk /dev/sdb
root # mkfs.vfat -F 32 /dev/sdb1

Install grub4dos to USB drive

user $ wget http://download.gna.org/grub4dos/grub4dos-0.4.4.zip
user $ unzip grub4dos-0.4.4.zip
user $ cd grub4dos-0.4.4
root # ./bootlace.com /dev/sdb
root # mount /dev/sdb1 /mnt/usb
root # cp grldr menu.lst /mnt/usb/

Copy bootable UEFI update CD image to USB drive

root # cp ~/Downloads/1yuj18us.iso /mnt/usb/

Configure grub4dos

Add thinkpad-bios entry to grub4dos.

   /mnt/usb/menu.lst - Menu entry
title thinkpad-bios
map (hd0,0)/1yuj18us.iso (hd32)
map --hook
chainloader (hd32)
boot

Unmount and reboot

Now you are ready to reboot and update your UEFI.

root # umount /mnt/usb
root # reboot
