i had similar issues with same VIA 6421 heres how you fix it for windows 7
go to device manager and right click the via card and diable it
then browse to C:\Windows\system32\drivers\
find and delete the vmraid.sys file
go back to device manager and enable the port, it should then have a yellow symbol with exclamation mark on it
RESTART your computer and then open device manager and make sure the yellow symbol with exclamation mark is still beside the via card
windows will not see or be able to use any device attached to the port, but JF should be able to see it and use it without error or freezing.
ps if you were using windows driver you need to install via driver first, restart PC then do the above or else the system will keep on reverting to the windows driver.
As you can already read in my post, i already disabled the device and removed vsmraid.sys then re enabled the device in device manager, got the yellow exclamation so i knew it was windows disabled, yet i got a freeze up writing bank 3 and after that windows would not see the drive on the via card obviously because the driver was disabled, so this confirms that the driver must have been disabled in windows as nothing was detected on that port which for mine is 0x8c00, anyhow like i say nforce ftw
