[work] [ltp] thinkpad Mandrake 9.0 sound fix, region free DVD & PII 400 upgrade

[linux-thinkpad@linux-thinkpad.org]

I installed the PII 400 in a thinkpad 380Z that previously had a PII 233. No 
BIOS flash was needed. I downloaded the Thinkpad 380Z Hardware Maintenance 
manual from IBM. It showed complete disassembly instructions, and I followed 
them.

I previously installed a PII 333 in a Thinkpad 380XD Pentium 233. In this 
case, I flashed the BIOS to a PII BIOS prior to CPU upgrade. It is indeed 
possible to go from a Pentiun to a Pentium II depending on the Thinkpad model.
