X Series Thinkpads do not have an internal drive. If there is no Windows installed, the BIOS must be updated by booting from an USB drive or a drive that is integrated in the docking station. Since a while Lenovo provides BIOS updates in form of bootable CD images. Unfortunately, these images are intended to be used with the docking station's CD drive. If you do not own such a drive, things get complicated.
The problem is that current BIOS updates are quite large, about 3 MB in size. Booting from CDs typically works like booting from a 1.44 MB or 2.88 MB floppy disk. The floppy image is stored on the CD and is referenced in the CD's boot record. Because the BIOS update file are that large, they do not fit on such a floppy image. Thus, they must be stored on the CD outside the virtual floppy image. To access these files a driver for the CD drive has to be loaded. Since Lenovo's CD images are intended to be used with a docking station's CD drive, it is not possible to use them for BIOS updates by booting from an USB CD drive.
But there is hope. This page describes some approaches to solve the problem.
Approach 1: Use larger boot image and create virtual CD drive
The CD images provided by Lenovo can be modified such that a BIOS update is possible -- without loading any drivers. I (Joachim Selke) successfully updated my Thinkpad X60s using the following method.
My first idea was to take Lenovo's ISO CD image and modify it such that a USB CD drive can be used instead the CD drive in the docking station. Unfortunately, simply replacing the drivers is not enough. While doing the BIOS update, the USB ports seem to get disabled or something like that. To circumvent this problem I tried to create a RAM disk, copy the needed files to this RAM disk, and then use this RAM disk as some kind of virtual CD drive. However, there were some problems with this approach as reported below. For a description of this old approach see the section "Approach 2: Load an USB driver, create RAM disk and copy the files to the RAM disk" below. I developed a new approach to solve this problem and will describe it here.
The idea is to create a new bootable ISO image that is large enough to hold the original ISO file. This can be done by switching from the virtual floppy drive used by Lenovo's update disk to a virtual hard disk drive (for details, see the El Torito standard). Instead of loading the CD drive driver provided by Lenovo we load the [SHSUCD drivers]. This driver enables us to create a virtual CD drive from Lenovo's original ISO file.
I wrote a script to automate this steps and create a new ISO file from Lenovo's ISO file. This new ISO file can directly be used to update the BIOS. My script takes four arguments:
- the filename of Lenovo's original ISO file (e.g. /home/selke/Desktop/7buj23uc.iso)
- the filename of the new ISO file to be created (e.g. /home/selke/Desktop/out.iso)
- the location of shsucdrd.exe (e.g. /home/selke/Desktop/shsucdrd.exe
- the location of shsucdx.com (e.g. /home/selke/Desktop/shsucdx.com
Both shsucdrd.exe and shsucdx.com can be downloaded from [1].
To sum up, an example call of the script would be convertlenovo.sh /home/selke/Desktop/7buj23uc.iso /home/selke/Desktop/out.iso /home/selke/Desktop/shsucdrd.exe /home/selke/Desktop/shsucdx.com
Note that you need recent versions of the following tools:
- mkdosfs
- mkisofs
The script runs perfectly on my Fedora 8 system (it should also run without problems on Fedora 7 and other popular distributions). If there are problems, please tell me (Joachim Selke).
Further note that the script at some point requires you to enter the root password since it must mount a disk image. As far as I know, this cannot be done without root privileges.
What does the script do? I will give a short overview:
- Extract the boot floppy image from Lenovo's bootable ISO file.
- Create a new boot hard disk image and copy both the boot sector and the files from Lenovo's boot floppy image to the new image.
- Copy Lenovo's ISO image to the new hard disk image.
- Also copy the SHSUCD drivers to the hard disk and change autoexec.bat and config.sys accordingly. When booting this hard disk image a new virtual CD drive will be created by SHSUCD. This virtual CD drive will have Lenovo's original ISO disc "inserted."
- Create a new ISO file that only consists of the boot image given by the bootable hard disk image just created.
Here is the complete script (save it as convertlenovo.sh):

If you have any questions, feel free to ask. :-)
BTW: It would be much simpler if I simply could put the new ISO images for download somewhere. But I guess for legal reasons this will not be possible.
Approach 2: Load an USB driver, create RAM disk and copy the files to the RAM disk
I ( Joachim Selke) successfully updated my Thinkpad X60s using the following method.
My first idea was to take Lenovo's ISO CD image and modify it such that a USB CD drive can be used instead the CD drive in the docking station. Unfortunately, simply replacing the drivers is not enough. While doing the BIOS update, the USB ports seem to get disabled or something like that. To circumvent this problem I tried to create a RAM disk, copy the needed files to this RAM disk, and then use this RAM disk as some kind of virtual CD drive. However, there were some problems with this approach as reported below.
- Download the ISO image style BIOS update from Lenovo's website. This file will be refered to as /tmp/bios-lenovo.iso.
-
Extract the floppy image from this ISO image. You can use the following shell script for this task (or an alternative one from [2]). Simply save this code into the file /tmp/extractbootimage.sh, set the x-flag (chmod +x /tmp/extractbootimage.sh) and call it using the command /tmp/extractbootimage.sh /tmp/bios-lenovo.iso /tmp/bios-lenovo.img. The floppy image contained in the ISO image will then be saved to /tmp/bios-lenovo.img. Here is the code of the shell script:
#!/bin/bash # This script extracts the floopy boot image from bootable ISO images # # Written by Joachim Selke (mail@joachim-selke.de), 2007-04-07 ISOFILE=$1 IMAGEFILE=$2 if [ ! -r $ISOFILE ]; then echo $ISOFILE: file does not exist or is not readable exit 1 fi if [ -z $IMAGEFILE ]; then echo Error: no image file specified exit 1 fi ISOFILESIZE=`stat -c %s $ISOFILE` # collect El Torito data # see http://www.phoenix.com/NR/rdonlyres/98D3219C-9CC9-4DF5-B496-A286D893E36A/0/specscdrom.pdf for reference BOOTCATALOGPOINTERBYTE=$((17 * 0x800 + 0x47)) if [ $ISOFILESIZE -lt $(($BOOTCATALOGPOINTERBYTE + 4)) ]; then echo ISO file is too short, possibly damaged exit 1 fi # absolute pointer to first sector of boot catalog: BOOTCATALOG=`od -A n -t x4 -N 4 -j $BOOTCATALOGPOINTERBYTE $ISOFILE | tr -d [:blank:]` BOOTCATALOGBYTE=$((0x$BOOTCATALOG * 0x800)) echo Boot catalog starts at byte $BOOTCATALOGBYTE if [ $ISOFILESIZE -lt $(($BOOTCATALOGBYTE + 32 + 2)) ]; then echo ISO file is too short, possibly damaged exit 1 fi # media type of boot image # only floppy disk images are supported by this script BOOTMEDIATYPE=`od -A n -t x1 -N 1 -j $(($BOOTCATALOGBYTE + 32 + 1)) $ISOFILE | tr -d [:blank:]` if [ $BOOTMEDIATYPE -eq 1 ]; then echo Boot media type is 1.2M floppy disk IMAGEBLOCKS=$((1200 / 2)) elif [ $BOOTMEDIATYPE -eq 2 ]; then echo Boot media type is 1.44M floppy disk IMAGEBLOCKS=$((1440 / 2)) elif [ $BOOTMEDIATYPE -eq 3 ]; then echo Boot media type is 2.88M floppy disk IMAGEBLOCKS=$((2880 / 2)) else echo Boot media type is $((0x$BOOTMEDIATYPE)). This type is not supported yet. exit 1 fi # absolute pointer to start of boot image BOOTIMAGE=`od -A n -t x4 -N 4 -j $(($BOOTCATALOGBYTE + 32 + 8)) $ISOFILE | tr -d [:blank:]` BOOTIMAGEBYTE=$((0x$BOOTIMAGE * 0x800)) echo Boot image starts at byte $BOOTIMAGEBYTE if [ $ISOFILESIZE -lt $((0x$BOOTIMAGE * 0x800 + $IMAGEBLOCKS * 0x800)) ]; then echo ISO file is too short, possibly damaged exit 1 fi echo Extracting boot image ... dd if=$ISOFILE of=$IMAGEFILE bs=2K count=$IMAGEBLOCKS skip=$((0x$BOOTIMAGE)) echo Finished
-
Mount the floppy image as root using the loop device:
# mkdir /tmp/bios-lenovo.img-mnt
# mount -o loop /tmp/bios-lenovo.img /tmp/bios-lenovo.img-mnt
-
Download needed drivers. First download some USB drivers from Panasonic Japan. Save the file to /tmp/f2h_usb.exe This file is a self-extracting EXE file, that can be executed under Linux using Wine:
$ wine /tmp/f2h_usb.exe
-
Let's modify the floppy image:
$ cp /tmp/F2h/Usbaspi.sys /tmp/bios-lenovo.img-mnt/
$ cp /tmp/F2h/USBCD.SYS /tmp/bios-lenovo.img-mnt/
$ cp /tmp/F2h/RAMFD.SYS /tmp/bios-lenovo.img-mnt/
$ cp /tmp/srdisk/srdxms.sys /tmp/bios-lenovo.img-mnt/
$ cp /tmp/srdisk/srdisk.exe /tmp/bios-lenovo.img-mnt/
DEVICE = A:\SRDXMS.SYS DEVICE = A:\RAMFD.SYS DEVICE = A:\USBASPI.SYS /V DEVICE = A:\USBCD.SYS /D:TPCD001
Finally, edit the file /tmp/bios-lenovo.img-mnt/autoexec.bat replacing the last line (saying COMMAND.COM) by the following:
A:\SRDISK 10000 COPY *.* D: D: COMMAND.COM
Maybe the RAM disk gets a drive letter different from D: on your system. In this case, you have to change the above lines accordingly.
-
Unmount the floppy image (as root):
# umount /tmp/bios-lenovo.img-mnt
-
Copy the content of the original CD image to a new directory and create a new ISO file:
# mkdir /tmp/bios-lenovo.iso-mnt
# mount -o loop /tmp/bios-lenovo.iso /tmp/bios-lenovo.iso-mnt
$ mkdir /tmp/bios-new.iso-mnt
$ cp /tmp/bios-lenovo.iso-mnt/* /tmp/bios-new.iso-mnt
$ cp /tmp/bios-lenovo.img /tmp/bios-new.iso-mnt/boot.img
# umount /tmp/bios-lenovo.iso-mnt
$ mkisofs -relaxed-filenames -b boot.img -o /tmp/bios-new.iso /tmp/bios-new.iso-mnt/
- The file /tmp/bios-new.iso is the modified ISO file. Just burn it to CD and use this CD for updating your BIOS (boot from it using your USB drive). Please give some comments here if it worked for you.
Comments on Approach 2
- I have followed your excellent instructions. The CD booted, the update program ran but stopped working and responding while updating. Luckily the BIOS was not destroyed. Since destroying the BIOS is a very high risk, I am going to recover the original Windows on an old HD and will run the update exe update program from there.
- I followed these clear instructions, and like the comment above I ended up with a CD that booted but the update program stopped working and responding. An ALT-CTRL-DELETE rebooted my x60s, and it works so the BIOS must not have been damaged. I was trying to upgrade from version 2.08 to 2.11, I wonder if these instructions are somehow particular to certain versions? Latch 01:22, 14 June 2007 (UTC)
-
After following the above instructions, the program also stopped working while updating the BIOS. But after changing the drive letter from D: to C: (see code below), it everything worked fine. However, I had some trouble figuring out, which letter to choose over D: at first, as the BIOS Upgrade program started right away.
A:\SRDISK 10000 COPY *.* C: C: COMMAND.COM

Flashing the bios (2.12) works for me on a X60s (using drive c). Using the DVD-R on an USB-Hub did not work.

Approach 3: Alternative method using a USB stick
Note: none of the above methods worked on my X60s. This method worked for me, however. PhilipPaeps 16:41, 24 August 2007 (UTC)
This method was surprisingly painless once I convinced my ThinkPad X60s to boot DOS from a USB stick. I used VMWare and some mystical tool to get DOS on the stick. If you can find another way to get a bootable DOS stick, please update this section!
- Tell VMWare to create a virtual floppy image for you and format it under Microsoft Windows and tell it to create a system disk. You can do this by clicking into "My Computer", then right-clicking on the "Floppy" icon and selecting "Format". In the box that pops up, you need to check the box that says "Create an MS-DOS startup disk" and then click "Start".
- When you've done that, get this tool: http://www.techpowerup.com/downloads/330/mirrors.php and install it. The tool is apparantly something HP once wrote, but I have been unable to find a link to it anywhere on the HP website.
- In a command prompt again:
C:\DriveKey\HPUSBF.EXE E: -Q -B:A:\
, replacing theE:
with the "drive letter" associated with your USB stick (you can find this letter in "My Computer" under "Removable Storage"). WARNING: this wipes anything on the USB stick. You will end up with a USB stick which appears empty at this point, but there is DOS on it somewhere.
- Now mount the BIOS update ISO image from Lenovo as a virtual CDROM using VMWare again and copy the files from it to the USB stick:
copy D:\*.* E:\
.
At this point, you may want to fiddle with the splash image, as described elsewhere on ThinkWiki.
- Reboot and press F12, tell the BIOS to boot from your USB stick.
cd flash
;updtflsh.exe
Think happy thoughts. The ThinkPad will beep quite ominously (and loudly!) a couple of times. Do not let this worry you too much. After about three minutes, the program will ask you to press enter to restart and hopefully all will be well.
Approach 4: Alternative method to the above "alternative method"
This is based on the above "Alternative Method" and works on my X60.
1. Download the BIOS Update iso image and the USB Stick Formatter.
2. Now get access to Windows -- be it in an emulator, or a colleague's PC. Steps 3, 4, 5 needs Windows to complete.
3. Install the HP USB Stick Formatter.
4. Go to the directory where you installed the tool: e.g. C:\DriveKey and extract HPUSBF.EXE to HPUSBF\ (using WinRAR).
5. Run the HPUSBFW utility, selecting the location of system files as C:\DriveKey\HPUSBF, and format the USB stick.
6. Extract the iso image to the USB stick, for example to K:\7buj22us (K: being the USB stick).
7. On the target computer, boot with the USB stick and issue the commands "cd 7buj22us" then "command.com"
This brings up the BIOS flash interface and you can update your BIOS from here.
