People sometimes describe SCSI as requiring black magic (including sacrifricing goat's blood, or occasionally Lusers). 

  

 __Note:__ Do not underestimate the black majick involved in [SCSI]! If you don't have a terminator on the non-controller end, it might work for a while, and then never work again. Or it might work under some OS's but not others. Put a terminator on it already. While you're at it, ensure BOTH ends of each channel are terminated. Most modern cards have "Auto" termination, and this almost always works these days, but if unsure, set to "Enabled", terminate the end of the cable, and if you're unsure if your cable terminator is active or passive, enable "term. power" on at least one of the devices on the channel.

 Go to http://people.debian.org/~blade/install/preload/ and download the bf24 SCSI driver disc. Modules for the kernel included with Debian's bootfloppy-2.4 kernel are on this disc. It will make the woody install nice and smooth.
