Page 2 Installation Instructions: Roadrunner 030 & 040 AM-1000 / AM-1200 Upgrade

The performance achieved by a Roadrunner upgrade depends largely on the type of

hard disk drive you are using. With the Roadrunner hardware installed, an AM-1000 or

AM-1200 computer booting from a SCSI-1 hard disk drive connected to the Roadrunner

SCSI port will see a significant improvement in overall system performance. However,

maximum performance is achieved when a SCSI-2 hard disk drive is used in

conjunction with Roadrunner hardware.

The Roadrunner hardware does not support an ST-506/Xebec controlled drive as a boot

device. However, Section 5.4 describes how you can access your ST-506 drive as a

subsystem device connected to the SASI port, for the purpose of transferring software

to a SCSI drive attached to the Roadrunner board’s high performance SCSI port.

A typical Roadrunner upgrade will include the installation of an AM-172 or AM-174

board, an AM-985 board, and a new 3-1/2" SCSI disk drive. SCSI disk drives ordered as

part of a Roadrunner upgrade may be factory loaded with a bootable copy of

Roadrunner compatible AMOS software. 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.
