If you need SCSI controller support during your installation, select one of the bootdisk images with a name ending in '.s'. NOTE: Just because your machine has a SCSI controller in it doesn't necessarily mean that you need to install with a SCSI bootdisk! If your Linux partition is on an IDE drive, and you're not installing from a SCSI CD-ROM drive, you should probably use an IDE bootdisk like "bare.i". Once the installed machine is up and running, you can edit /etc/rc.d/rc.modules to load the kernel module to support your SCSI card.
