I have a quick question I have a Sony VGN-SZ4MN which, as standard, is loaded with the R0112N0 bios (SLIC2.0). This site contains SLIC 2.1 versions of this BIOS. Am I safe (reasonably) to be able to use the SLIC 2.1 BIOSes posted or do I need a specifically modded version for my machine? I can't find reference to the SZ4MN Thanks
