Thanks for the link. It also looks like I messed up the process by not 
installing ACPI. I had found some "workarounds" for the VMWare problem, but 
they didn't work for me, (could be that I didn't get them right). The VMWare 
support people worked extensively with me during the BETA of 5.0 and none of 
their magic incantations worked either. I suspect it has something to do with 
late level hardware as you suggest. I bought this hard drive just for the  
purpose of running Linux on the system while preserving the ability to go 
back to "factory" when I need to. 

FWIIW: be careful of what brand/model drive you use if you want to swap out 
the main drive. I have a Hitachi that causes an error when you power on, 
(hitting F1 WILL boot the system though). The Fujitsu I bought works fine 
(that is what IBM/Linovo put in the system to begin with). 

Thanks again, glad I found this list. I have been running Thinkpads for over 
10 years, but this is my first serious experience with Linux.
