Page 2 Installation Instructions: Roadrunner 030 and 040 AM-2000M Upgrade
Depending on your order, some SCSI disk drives are factory loaded with a bootable
copy of Roadrunner compatible AMOS software. If you ordered a SCSI disk drive
without the factory loaded software or if you choose to use your existing drive, you will
need to download and configure a Roadrunner compatible AMOS operating system
using the instructions found in Appendix C at the end of this document.
