I just installed pure64 on a few machine with 3w-9500 RAID cards. The basic
problem is that the card is not autodetected, so the initrd image doesn't
contain the modules necessary to bring up the root fs.

I fixed it by, at the end of the install, dropping to a console and editing:

/etc/mkinitrd/modules, adding the line '3w-9xxx'


/etc/mkinitrd/mkinitrd.conf, replacing MODULES=most with MODULES=all

then rebuilt the initrd

mkinitrd -o /boot/myimage.img 2.6.8-3-amd64-k8-smp

then edit /boot/grub/menu.lst and change the boot image for your default
kernel to the 9500-aware image.

reboot and cross your fingers.

good luck,
