Anyone know if i Can use the .fl1 in ibm bios redestribution file for reprogramming tsop?

Will it boot to a diskette drive?

If it does, it can be reprogrammed. The flash program used in the IBM diskette is called Phlash and it can be used directly from the A: prompt.

I would assume you can do the same on an external programmer.

Have you thought of just finding the right pins and just wiring them to another ThinkPad instead. Removing the chip and resoldering sounds like a lot of work to me.

Good luck!
