I've updated the BIOS and it still suffers from the same problem. Also the 
R40 with the latest BIOS suffers from this problem. (The Changelog doesn't 
mention such a problem fixed so there wasn't any hope anyhow ;)))

So maybe nice to have it listed somewhere that these machines don't allow 
to boot from USB using memdisk:

	Thinkpad T30 with BIOS <= 2.06 - 1IET67WW
	Thinkpad R40 with BIOS <= 1.18 - 1PET50WW

I can try later on a T23 too, but I fear that it won't make a difference.
Is it possible that all the Thinkpads have this failure, or is it maybe 
some conflict between memdisk and the BIOS that has not been discovered 
yet ?

Is there something I can do to debug the problem or to get more 
information so someone else can debug this ?

Thanks in advance !
