This page describes how to replace the standard IBM BIOS Bootsplash (The one with the ThinkPad- and Pentium M-Logo), without access to Microsoft Windows or a floppy drive.

Windows users who want to have a custom splash image when they start up should try [[How to change the BIOS bootsplash screen (under Windows) | this guide]] instead.

== Getting the Files ==
You'll need the bios upgrade file from the IBM website.

=== Method 1: Using a Non-Diskette-File and cabextract ===

For ThinkPads {{R50}}, {{R50p}}, {{R51}} (1829, 1830, 1831, 1836), {{R52}}, {{T40}}, {{T40p}}, {{T41}}, {{T41p}}, {{T42}}, {{T42p}}, {{T43}}, {{T43p}} this file is suitable:
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj28us.exe 1ruj28us.exe]
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj29us.exe 1ruj29us.exe]
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj30us.exe 1ruj30us.exe]
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj33us.exe 1ruj33us.exe]
There may be a more recent file on the IBM website.
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj35us.exe 1ruj35us.exe]

For Thinkpads {{T61}}, {{R61}} 14.1 inch screen
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/7luj05us.exe 7luj05us.exe]

You need the cabextract tool to extract files from the exe:
:{{cmdroot|apt-get install cabextract}}

Do this to get the ibm file and extract the disk image from it:
:{{cmdroot|cd /tmp}}
:{{cmdroot|wget ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj35us.exe}}
:{{cmdroot|cabextract -F "*.IMG" 1ruj35us.exe}}
:{{cmdroot|mv 1RUJ35US.IMG floppy.bin}}

=== Method 2: Using a Diskette-File and dosemu ===
Another option is to use the "Diskette BIOS file".<br>
For ThinkPads {{R50}}, {{R50p}}, {{R51}} (1829, 1830, 1831, 1836), {{R52}}, {{T40}}, {{T40p}}, {{T41}}, {{T41p}}, {{T42}}, {{T42p}}, {{T43}}, {{T43p}} this file is suitable:
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj28ud.exe 1ruj28ud.exe]
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj29ud.exe 1ruj29ud.exe]
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/1ruj30ud.exe 1ruj30ud.exe] Released 2005-05-26

For Thinkpads {{T61}}, {{R61}} 14.1 inch screens
* [ftp://ftp.software.ibm.com/pc/pccbbs/mobiles/7luj05us.exe 7luj05ud.exe] Released 2007-07-16 '''NEW!'''

The file is an OS/2 executables and don't run with wine, so you need to install dosemu to run it and create the image.<br>
:{{cmdroot|apt-get install dosemu dosemu-freedos}}
(for non-debian-users: Get dosemu and freedos somewhere and make it work somehow).

With dosemu, you can run this executable, but this program unfortunately
needs a floppy drive to write to. So use the loopback device, to create a virtual floppy.
:{{cmdroot|1=dd if=/dev/zero of=/tmp/floppy.bin bs=1024 count=1440}}
:{{cmdroot|losetup /dev/loop0 /tmp/floppy.bin}}
Put this block device ({{path|/dev/loop0}}) into the dosemu configuration as the floppy disk device.
Now you can run the extractor executable, which makes {{path|/tmp/floppy.bin}} the desired floppy image .
:{{cmdroot|dosemu 1ruj27ud.exe}}
:{{cmdroot|losetup -d /dev/loop0}}

For 2.6.12+ if you have dosemu error:
:{{cmdroot|echo 0 > /proc/sys/kernel/randomize_va_space}}

== Adding the custom image ==
Mount your floppy.bin as a loopback device.
:{{cmdroot|mkdir /tmp/mnt}}
:{{cmdroot|1=mount -o loop,umask=000 /tmp/floppy.bin /tmp/mnt}}
Create a 16 color 640x480 BMP (4 Bit/pixel VGA palette) (for example with Gimp) and save it to {{path|/tmp/mnt/logo.bmp}}.

When creating your image, keep in mind that on the T43p (and others??), regardless of your custom bootsplash screen there will be a superimposed black "Centrino" logo (~100x100 pixels) on the upper right of your display, so you might want to keep that area clear. You might also want to reserve the bottom 150 pixels for the "boot options" / "Entering BIOS setup" message(s) too, which will also be displayed.

Now prepare the image with <tt>prepare.exe</tt> using wine: (This does not work with dosemu!)
:{{cmdroot|wine prepare.exe logo.scr}}

The image must compress to <10k. If you receive an error, you can try reducing the number of colors in your image palette (step down to an 12 or 8 color palette for a very significant reduction in image size.) When successful, there should be a new {{path|logo.mod}} and your {{path|logo.bmp}}. If so, you are set, don't forget to unmount your loopback device:
:{{cmdroot|umount /tmp/mnt}}

== Fake a floppy ==
Now you need to put the image on a floppy and boot from it. Since recent ThinkPads don't have a
floppy drive, we can use a CD-R (or a CD-RW, actually, for the cheap ones, like me) and burn it with the following command:
:{{cmdroot|1=mkisofs -b floppy.bin floppy.bin <nowiki>|</nowiki> cdrecord dev=<device> - }}
(<tt><device></tt> being your cd writer device)

== The exciting part ==
After this worked, reboot your ThinkPad from the cdrom by pressing F12 while booting
and wait for the IBM tool to start.
Be sure to have your ThinkPad on AC power and say ''Yes'' to the questions the BIOS Upgrade Tool asks.
It will then flash the BIOS, which will take about a minute.

Suddenly the laptop turns itself off with two beeps.
When booting, you'll have your bootsplash picture.

Unfortunately, you won't see it really long, but it's better
than the standard one, so it was worth the action.

Have fun!

BTW next time you have to flash the BIOS the IBM BIOS updater will detect a custom boot splash and ask you if you want to preserve it or restore the original.

== Share your custom bootsplash image ==
If you've created your own bootsplash image and want to share it with other you can post it here.

* Schnappi bootsplash: Bow to the power of [http://folk.uio.no/igorr/t43/final.bmp Schnappi]. The BMP image compressed to about 6KB. Schni, schna, schnappi!
* IBM Tux: An image of [http://users.tkk.fi/~jpaalija/stuff/filestorage/ibm-tux.bmp Tux with the IBM logo] written on its tummy.
