SUMMARY
This article explains the significance of renaming a new bid for a boot drive to spare001.sys or bootbid.bid.



MORE INFORMATION
When you are booting your system, your machine designates the first disk it finds as boot disk. If you have two SCSI controllers, laddr boots from the one it finds first by default. If you want to boot from the other one, rename it boot.bid so that ddr will find it first from then on.

SPARE001.SYS was set up because any bid that is not registered in IOCFG01.SYS is not tried as the laddr drivers are loaded. If you rename any new bid that comes out to SPARE001.SYS, it will be tried as well. The other option is to include a &quot;device = &quot; line in CONFIG.SYS.
