The solution to this problem is SCB Paging, a concept similar to Adaptec AHA-2920 SCSI paging. SCB paging takes advantage of the fact that devices usually disconnect from the SCSI bus for long periods of time without talking to the controller.

The SCBs for disconnected transactions are only of use to the controller when the transfer is resumed. When the host queues Adaptec AHA-2920 SCSI transaction for the controller to execute, the controller firmware will use a free SCB if one is available. Otherwise, the state of the most Adaptec AHA-2920 SCSI disconnected and therefore most likely to stay disconnected SCB is saved, via DMA, to host memory, and the local SCB reused to start the new transaction.

This allows the controller to queue up to transactions regardless of the amount of SCB space. Since the local SCB space serves as a cache for disconnected transactions, the more SCB space available, the less host bus traffic consumed saving and Adaptec AHA-2920 SCSI SCB data.

Hannum, Michael Graff, Jason R. Controllers with this problem have a 42 MHz clock crystal on them and run slightly above 10MHz.

This confuses the drive and hangs the bus. Target mode is not supported on NetBSD version of this driver.

Most modern motherboards perform the initialization correctly and work Adaptec AHA-2920 SCSI with this option enabled. For systems that store non-volatile settings in a system specific manner rather than a serial EEPROM directly connected to the aic7xxx controller, the BIOS must be enabled for the driver to access this information.

This restriction applies to all EISA and many motherboard configurations. Performance and feature sets vary throughout the aic7xxx product line.
