Latest drivers are downloaded automatIcally with win7 64 bit. I never had to zsearch for anything.
semp
did it automatically install your MB drivers?
like for the North Bridge/South Bridge, USB drivers, MB/processor drivers, OnBoard Sound card driver, On Board LAN driver, SATA Controller Drivers, RAID Drivers ( if used )..etc.....
reason I ask, is sometimes one might need a specific driver for their MB and if it is not signed by MS then it is not gonna load it, to where if one goes to their Components Manufacturer's website ( or Components CD ) they can have what works for their board.....or Video Card, or PCI Sound Card, etc.....
example...... I installed windows 7 on my Mom's PC...it picked everything up, all worked fine...but it IMPROVED when I went and loaded her MB drivers for her Motherboard.......
YMMV
edit: as BaldEagl has posted... needing to FLASH one's BIOS is on a "only if Need to" basis........ like possible PC performance increase, or the existing BIOS might have an issue with certian PC components, or for example, if I wanted to upgrade to an AM3 processor, my ASUS MB needs an updated BIOS instaled/flashed...to where right now it will only accept AM2 & AM2+ processors with the current BIOS I am using......
hope this helps
