If you want to use SCSI then you'll have to limit > memory to 3.5 GB. What you're saying is that Adaptec and LSI Logic SCSI controllers behave badly (and can cause data loss) on amd64 systems which contain more than 3.5GB of RAM. This is a very big claim. Have you talked to Scott Long about this? Please expand on this, and provide evidence or references. I need to document this in my Wiki if it is indeed true. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
