SCSI Passive Device masker.

Ok. I have a bitchy SCSI host card, the ever-popular Adaptec 2930UW. Great card, still sold to this day for 109 dollars. Bios updates are fast and easy, and it'll take literally anything SCSI, Big 50, or UW68. I've got a few hard drives I use for primary backups I throw in there once in awhile. But sometimes, games, or other programs (Corel Paint Shop Pro X and Fruity Loops 6) won't install from the disk because of how I've got my SCSI set up. Well, I found a neat little program that hides SCSI passive devices (Optical Devices, tape drives, crap like that.) and they're treated as SATA/ATA devices, I'm not sure which.

YASU.
Run once to enable hiding of Passive SCSI devices, run again to disable.
