There's another way of installing - bootstrap the install from another machine. Once you've installed Slackware, try replacing the /dev/hd?? entries in /etc/fstab to /dev/sd?? for them to be seen as SCSI devices. Upgrade to the latest 2.4 or 2.6 kernel to enable SATA support. Note that you need to compile SCSI and SATA support directly in the kernel for you to be able to even boot it the next time you run that kernel. As for RAID support using the Promise controller 20378 - forget it. The Promise 20378 RAID driver is partially software based - better stick with Linux software RAID, or buy another RAID controller (the 3ware Escalade SATA RAID controller works afaik). There's incomplete support for the ICH5 chipset's SATA RAID in the current state of Linux libata code. -- Paolo Alexis Falcone [EMAIL PROTECTED] -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
