I had the freezing problems when trying to erase in jf using via 6421 and maximus extractor through usb
Podger posted a while ago about this but for some reason it dosnt seem to have cought on
I installed the VIA_RAID_V530C which can be found here
http://www.versiontr...einfo/win/70826 and the problem was sorted

No boot disk or dos or rebooting pc required, you can do the whole thing in 1 go

Thank's again podger

i couldnt get your link to work so heres an alternative for anyone having the same problem
