In what order do I up[date BIOS and load system drivers?
I'm just starting to do a heart transplant on my 8 year old machine and things seem to be different now. All the previous times I built a system, I assembled the electronics, loaded and ran a floppy that loaded the drivers, set up partitions, loaded the operating system (s) and then each of the aps. When I read in the user manual how to update the bios if needed, I opened the box for the first time and looked for the system disk. There was none. I looked on ASUS but could not find a way to download a system disk nor any comments about that step. I couldn't find a voice phone for MicroCenter and after some confusing texts, MicroCenter assured me that there was no disk-- the system drives would be downloaded from the web site. I also found a cute little leprechaun sized USB drive with a clam shell pictured on it which I decided was probably to be used to update the Bios. So much for playing Adventure before building the box.
So here are my two questions: Do I need to load the bios as a first step after POST or do I wait later in the process and check to see if it is up-to-date? Something I overheard on this forum suggested that maybe MicroCenter had already done the update. Maybe that was why the box was not sealed? (There is a 1/4" red dot sticker on the ID sticker but it is not dated.)
The second question is: do I download all the various drivers before loading the operating system or wait until the OS is loaded and updated before checking dates and versions? If I wait until after the Windows OS is loaded will Windows try to load all the drivers and maybe choose the wrong source?
