Only 15 devices can be configured on each adapter. When target mode is enabled, this adapter appears as a processor device on the other system and unless you have specialized software that can communicate between the two systems through these processor devices (peer-to-peer communication), there is no advantage in having target mode enabled. When target mode is disabled, this adapter does not appear as a device to the other system, and one more device can be shared by the two systems. If your system is not sharing any SCSI devices with another system on this adapter, it does not matter whether you enable or disable target mode. The normal default for this option is enabled." NamedItem Prompt "SCSI Disconnect" Choice "Enabled" pos[5]=X0XXXXXXb Choice "Disabled" pos[5]=X1XXXXXXb Help "Disconnect is a SCSI-bus procedure in which a device logically stops communicating with the adapter during certain operations and then reestablishes communication with the adapter when the operation is complete. Disconnect should not be confused with the 'Presence Error Reporting' option for a device in 'Set and view SCSI device configuration.' If you are using an operating system that is single-threaded and issues commands to only one device at a time (such as DOS), disabling SCSI disconnect might result in a slight performance improvement. If your operating system is multi-threaded (such as OS/2), disabling SCSI disconnect will degrade the performance of the SCSI subsystem. The normal default for this option is enabled."

ADPItem 1 prompt "ROM Address Range" EXEC Help "This field shows the address of the 32K block of memory that is assigned to the adapter. Only one SCSI Adapter will have the ROM assigned, and any other SCSI Adapter installed will share that address range. If you are in the 'Change Configuration' window, you can change the setting. Use F5 and F6 to scroll through the choices, the Up and Down arrow keys to move from field to field. If a setting conflicts with another, an asterisk (*) appears next to the conflict. You must fix conflicts before you use the adapter. If the ESDI adapter is also installed, then the address of the SCSI adapter must be greater than the ESDI adapter address."
