For PowerBook 5300 series computers. Addresses a potential conflict with slow SCSI devices such as 1x CD-ROM drives (like the Apple CD150), Zip drives, and PowerBook in SCSI disk mode. Not all PowerBooks will experience the problem and a PowerBook that does may not experience the problem all the time (even with different units of the same make and model). You should only install this extension if you are experiencing constant freezes or crashes when transferring files with a particular slow SCSI device. Installing this extension will degrade performance with ALL SCSI devices by 10 to 50 percent.
