It convinces some pre-SCSI2 disks which use  CCS command set (very close to
SCSI2) to answer like a SCSI2 disk. Without it, it acts like a SCSI1 device.

My Micropolis MP 1624 is one of them. 

(ahb0:1:0): "MICROP 1624-07MZ1077801 HZ2P" type 0 fixed SCSI 2
sd11(ahb0:1:0): Direct-Access 642MB (1316751 512 byte sectors)
sd11(ahb0:1:0): with 2112 cyls, 7 heads, and an average 89 sectors/track
