Hey there, I've been searching around and trying out the various tools to edit my SMBIOS, in specific my System Information structure (Type 1 UUID) but have had no luck! I've managed to rename my motherboard and manufacturer name to the correct strings. However I have been unable to change my UUID as SMBCFG.exe displays that it is READ-ONLY. I've created a flash drive to boot win98DOS and tried a number of other programs; I've attempted to use DMIDOS.exe but it will not work, instead displaying an odd screen that looks like a rainbow died at the bottom. I have an image avaliable but I don't think it is necessary atm. My OS is Windows 7 x64 Ultimate My Motherboard is an ASUS P6X58D-E My Bios is American Megatrends Inc. 8303. My SMBIOS version is 2.5 I am running an Intel i7 930. Some of the programs I've tried have dead links so I haven't had a chance. Lost and without anymore ideas or patience, I've posted a thread to seek out help. I am happy to give additional details if requested to the best of my abilities. I am completely new to playing around with my BIOS and have so far only done some trivial things like name my manufacturer ASSus, I'm interested in perhaps delving into far more useful functions but at the moment, I am dedicating my efforts into trying to change my UUID. Thanks!
