Note: Read the AHA-1530P/1532P Getting Started guide first when you are ready to install your AHA-1530P/1532P Plug and Play host adapter. Getting Started explains Plug and Play technology and tells you how to make your PC Plug and Play ready before you install the host adapter. 1 Overview This Installation Guide explains how to physically install and configure Adaptec AHA-1530P/1532P Plug and Play SCSI host adapters.
2 Host Adapter Layout This diagram and the following table show the major AHA-1530P/1532P components.

Plug and Play may override some default settings when it assigns system resources. Section 6, Configuring the Host Adapter, explains how to change settings with the SCSISelect utility. 4 Installing the Host Adapter Inserting the Host Adapter Follow these steps to insert the host adapter in a slot: WARNING: Turn OFF and disconnect the power to your PC and attached devices before you remove the chassis cover. See your PC’s documentation for instructions.
Disabling the BIOS The AHA-1530P/1532P onboard BIOS is enabled by default. This allows you to boot your PC from a SCSI disk drive connected to the host adapter. It also allows you to run the SCSISelect utility when your PC boots, as described in Section 6. However, when the onboard BIOS is enabled, the host adapter ’s IRQ and other resources are fixed and cannot be reassigned by Plug and Play, unless the PC motherboard BIOS supports Plug and Play.
If you need to set SCSI IDs with switches or jumpers, we recommend that you assign SCSI IDs 0 and 1 to the first two SCSI hard disk drives. Terminating SCSI Devices The SCSI bus is the cabling that connects SCSI devices to the AHA-1530P/1532P. Data can only be transmitted on the SCSI bus if the devices at each end of the bus are terminated. Termination must be disabled on all other devices on the SCSI bus. Termination on the host adapter itself is controlled by software commands via the SCSISelect utility.
Connecting Internal SCSI Peripherals Caution: AHA-1530P/1532P host adapters support only single-ended SCSI devices. Do not connect differential SCSI devices to the host adapter. Read the device documentation to determine whether a SCSI device is singleended or differential. Follow these steps to connect the host adapter to SCSI devices mounted inside the PC case. Use the internal SCSI cable included with your host adapter. 1 Disable termination on all internal SCSI devices.
Connecting External SCSI Peripherals Follow these steps to connect the host adapter to SCSI disk drives, CD-ROM drives, and other external devices. 1 Attach the connector of a 50-pin, high-density external SCSI cable to the host adapter ’s external SCSI connector. (External cables can only be plugged in one way, so pin-1 orientation is automatic.) 2 Plug the other end of the cable into one of the two SCSI connectors on the back of the first external SCSI device.
6 Configuring the Host Adapter Your host adapter includes the SCSISelect utility, which lets you change configuration settings without opening your PC or editing configuration files. Running the SCSISelect Utility If the AHA-1530P/1532P onboard BIOS is enabled, you can start the SCSISelect utility by pressing Ctrl-A when the prompt appears at boot time. If the AHA-1530P/1532P onboard BIOS is disabled, you must run an executable version of SCSISelect called 1530cfg.exe.
Select Advanced Configuration Options to view a menu of the following options: Host Adapter BIOS Enable/Disable, Support Removable Disks under BIOS as Fixed Disks, and Extended BIOS Translation for DOS Drives > 1 GByte. Do not change these options unless absolutely necessary. SCSI Disk Utilities When you select SCSI Disk Utilities from the Main Menu, a list of installed SCSI devices appears. When you select a device, the Utilities menu appears. Format Disk runs the Adaptec SCSI low-level format utility.
■ Make sure all SCSI devices have unique SCSI IDs. ■ Make sure the SCSI bus is correctly terminated. (See Section 5, Connecting SCSI Peripherals.) 9 Switch Block Settings The five switches on switch block s1 are all set to Off by default, as shown in this diagram: 5 4 3 1 2 OF F This table shows all the possible settings of the switches on switch block s1. Default settings are marked with an asterisk (*).
