Disabling SCSI Sync Negotiation

Use the following instructions if you need to disable the SCSI sync negotiation, which forces the
controller to transfer data at a specified rate (slower than its capability) for the target devices.
To disable sync negotiation:
1. Power off the system and reboot into DOS using the SYSUTIL diskette.
2. From the SYSUTIL main menu, select SCSI Select Utility.
3. From the Options box, select Configure/View Host Adapter Settings.
4. Select the SCSI Device Configuration option.
5. Change the Initiate Sync Negotiation values for all the attached SCSI devices
(represented by their SCSI ID number) to no.
6. Set the Maximum Sync Transfer Rate values for the devices to the desired settings. If
changing these settings to extend cable lengths or add more devices, set Ultra SCSI devices to
10.0 or less.
NOTE The Advanced Configuration Option allows you to disable the Ultra SCSI controller. When Ultra SCSI
is enabled, the available sync rates are 20, 16, 13.4, 10. When Ultra SCSI is disabled then 10, 8, 6.7,
5 are available.
7. Press
ESC
8. Press any key to restart the system.
