@heslo Because using afudos /ibios.rom /pbnc /n (where bios.rom is an example filename) you will flash also bootblock area which contains SLIC (in other words 1B module will be totally rewritten) while flasing via windows (asus update) it's not sure you'll see SLIC. Anyway flash it and report feedback.
Anybody out there, who have a Asus P5K MoBo (newest BIOS is 1201) who have already sliced it with the new marker 2.1. (Cant wait to hard-activate Server 2008) Bye
Just use the tool, that is most likely the method that will be used anyhow.. Else it may be a little bit..
