Ok, so one of the components needs to contain 3ware 9xxx drivers, as well as 7/8xxx. The head node of my cluster, which should be arriving RSN, has all its disks connected to the 3ware card. -- #define X(x,y) x##y Peter Cordes ; e-mail: X([EMAIL PROTECTED] , des.ca) "The gods confound the man who first found out how to distinguish the hours!

amd64 installation images
Hi. I am planning to deploy the amd64/pure64 version of Debian on a new system. However while investigating the netinst images at http://debian-amd64.alioth.debian.org/debian-installer/daily/netboot/ I noticed that the initrd misses something I would need in there: the 3ware 3w-.ko and/or 3w-9xxx.ko kernel modules. Would it be possible to add those to the initrd? It seems that the 3ware 9000 series is pretty popular among AMD64 users. cu, sven
