600E 2645-4AU
  • George Tellalov <>. BIOS 1.16 from spsdin36.exe worked perfectly with the method bootable cd from floppy image. I highly recommend this upgrade because it made my ibm-acpi module load (it wouldn't load before) and fixed some suspend to ram problems. Here's the cd image I used. Use at your own risk. You can send me a chocolate if it works for you ;)
600E 2645-5bU
  • Mike Vincent<>. Bios 1.16 from spsdin36.exe and then to the boot cd worked great for me. Thought I had bricked it three separate times using a "real" floppy! Each from different diskettes .The updater would start, give me the "going to take30 seconds" speech...and then access the HD for 10 minutes. Each time it would reboot fine. Did the cd as described above...worked great first time. Perhaps 10 year old seldom used floppy disc drives have some challenges?
600X 2645
  • Jonathan Byrne <>. BIOS 1.11 from spsuit55.exe worked perfectly using cabextract/CD method.
600X 2645
  • Andy Barnes <>. As per Jonathan above, extracted BIOS 1.11 from spsuit55.exe using cabextract, created a CD boot image and burnt to CD. Worked flawlessly - thanks to everyone who contributed to this article!

A21e 2628-JXU
  • Amit Gurdasani <gurdasani at yahoo dot com>. BIOS 1.13 flashed fine with cabextract/CD method. Alarmingly, after the BIOS update, the laptop beeped but did not shut down as was indicated onscreen -- that was frozen on the "do not shut down the laptop" screen. On power down and up again, the BIOS setup showed the newer BIOS image running, and Linux booted up fine. Linux ACPI didn't complain about the BIOS being too old either.
A31p 2653
  • Matthias Meinke, BIOS 1.09 1NET15WW flashed fine with cabextract/CD method.
A31 2652
  • Aaron Denney, BIOS 1.13 flashed fine with cabextract/CD method. The cabextract/CD method also worked for BIOS 1.10.
  • Jarrod, 30 August 2007, Thinkpad R30 Type 2656-E0M. BIOS updated to 1.40 (1CETF0WW) using floppy disk/mkisofs/cdrecord. Worked fine, no problems.
  • Matthew Lambie,
  • Antti S. Lankila, update to 1.27 via direct use of phlash16.exe against a BIOS image. Normal method did not work because the battery is dead.

Booted with external USB optical drive (I have internal drive broken) - at the beginning of the boot sequence press PAUSE, then wait several seconds, then ENTER, then F12 and select the drive. Without pressing PAUSE I am not able to boot from USB optical/hard drive as the drive does not show in the F12 boot list menu.

cabextract & unetbootin are staight foward(toggle floppy image instead of iso image in unetbootin dialog) No problems with update software. x31 has to be cajoled into booting from usb. Boot hangs when pendrive is present. Hit the key to bring up the boot menu. Unplug the pendrive. Let the boot menu come up. Plug in the pendrive. Select the pendrive in the boot menu and it boots.
