Let me clear. M09 does not mean automatically Slic 2.1. Original A09 has M09 marker but still stay Slic 2.0 (slic 20 00 00 ... and key starts with 26 16 7E ...) I replaced only slic area. You can see this if you will search for "WINDOWS" (slic 20 01 00... and key started with 6E EF 2F ....) another areas are not changed. I did that with help of winhex without rebulding of the bios. Second method uses PBE (Phonix bios editor). In this case PBE reorders locations of different bios areas and writes more changed bios. All phonix methods with normal phonix bios here are based on this method. I prefer to do less changes. You can ask to do modification somebody also, but at least every slic change is a modification of original bios. Another question why new bios was not written correctly.
you can stop requesting on this machine because it only haves slic 1.0(xp). only machines with slic 2.0(vista) can be upgraded to 2.1(win7)
shakeyplace, do you mind sharing how to pack .hdr back into the dell .exe bios installer? please. thank you.
