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
root # nano /mnt/usb/menu.lst <pre> title thinkpad-bios map (hd0,0)/1yuj18us.iso (hd32) map --hook chainloader (hd32) boot </pre>
Unmount and reboot
root # umount /mnt/usb root # reboot
