Text for this description has to be done yet.. sorry.
The pictures will show enought about what are the steps needed to install an ACARD board.

The ACARD Bridge board lets you use usual IDE disks with you own Silicongraphics (and not only) computer
that have SCSI interfaces.. since they dont have IDE, and this makes lot of money to be saved
from your wallet :)
Not that the ACARD are cheap, but its surely cheaper than buying a 150Gb SCSI disk :)))

I really guess I need to say nothing about it and just let you jump watching the pictures.

cheers.
