Host Adapter Setup

DOS Space > 1 GB. Using this option allows for single disk capacities to be extended up to 8 GBytes (yes). Please refer to the Appendix titled DOS Space > 1 GB for further information on this feature.

•(NO) DOS limits the number of cylinders per drive to 1024. The host adapter defines head and sector usage to 64 heads and 32 sectors. This format allows for maximum capacity of 1 gigabyte per disk storage.

•(YES) The upper limit can be extended from 1 GByte to 8 GBytes by increasing the number of heads to 255 and sectors used per track to 63. This is a powerful option.

DATA CAN BE LOST BY CHANGING SETTINGS.

Spin Up Disk Drive. This option is used to initiate motor spin-up for SCSI disk drives. The host adapter BIOS can limit system power requirements during power-up. This is accomplished by signaling the device to start at delayed intervals (default setting will be ‘no’).

Enable Disconnect. The host adapter uses this option to allow a device to temporarily disconnect from the SCSI bus (referred to as disconnect/reconnect). This allows the host adapter to perform other functions on the bus while the device is temporarily disconnected. The device and the host adapter can then reconnect when the bus is needed (default setting will be ‘yes’).

Adapter Setup

Host Adapter SCSI Bus ID. Used to change the adapter’s SCSI ID on the SCSI bus. The narrow host adapters provides eight ID’s available numbered 0-7, with 7 having the highest priority (and ID-7 reserved for the host adapter).

Installation of additional host adapters is permitted on the same PCI bus. This will allow the system to have more than one SCSI bus attached. Under these conditions, SCSI ID’s can be repeated.

Boot Device ID. This option selects which SCSI device will be the designated boot device for the system. The default ID for this option is 0.

SCSI Terminators. This option is used to set auto-termination located on the host adapter card. This option is also used to manually control termination on the host adapter. The normal setting for this option is auto.
