____ 1. | Devices within peripheral subsystems shall not terminate the SCSI bus. |
____ 2. | Provides two 50-conductor high-density SCSI connectors on the external device enclosure with visible SCSI icons near the connectors. |
____ 3. | Supplies terminator power to the SCSI bus with a self resetting current limit device. |
____ 4. | Provide labeled manual SCSI ID switches for use with non PnP master host connections. Note: This item is recommended for backward compatibility and is not a requirement for full PnP SCSI systems. |
____ 5. | Ship with default SCSI ID per Table 1. |
____ 1. | Support SCAM level 1 slave protocol to request automatic SCSI ID assignment. |
____ 2. | Support the full PnP SCSI command profile if and when defined (CD ROM definition in process) |
____ 3. | Direct access devices return the actual number of user accessible logical blocks in response to the Read Capacity command. |
____ 4. | All peripherals support Synchronous Negotiation protocol to avoid hanging the bus. |
____ 5. | All peripherals support the SCSI INQUIRY command without significant delays. |
____ 1. | ISA adapters are required to meet the PnP ISA specification. |
1.1 Implement isolation circuit for unique card identification. 1.2 Identify resource requirements (IRQ, DMA, Memory and I/O space) in on board registers. 1.3 Provide software programmable resource options. | |
____ 2. | Use a 50-position high-density connector for external SCSI connections with a visible SCSI icon near the connector. |
____ 3. | Supplies terminator power to the SCSI bus with a self resetting current limit device. |
____ 4. | Supplies regulated termination: 4.1 For one end of the SCSI bus for internal only or external only SCSI chains. 4.2 Only if switchable terminator is at one end of the bus. |
____ 1. | Implement SCAM level 1 master protocol to automatically assign SCSI IDs. |
____ 2. | Adapter option ROM requirements: |
2.1 INT 13h BIOS extensions including logical block addressing for consistent geometry translation. | |
____ 3. | Implement PnP device drivers. |
