EISA Fast SCSI Caching Adapter
1.Set I/O port address as 330H.
2.Set the SCSI ID as 0 and 1 for fixed disk drives.
3.Device drivers are needed for other SCSI devices, such as removable cartridge, re-writable optical disk (MO), tape streamer, DAT, and CD- ROM.
4.If the DC-820B coexists with an AHA 1540/1542 adapter, you must set the I/O port address as 330H for Adaptec’s adapter and choose an I/O port other than 330H for this DC-820B. More information can be refer- enced in the following sections.
For DOS3.3/4.0/5.0/6.0 environments, the DOS 5 support enable/disable option provides you an opportunity to enhance some functions:
1.The limitations for both the I/O port 330H and SCSI ID starting from 0 no longer exist.
2.As for DOS 5.0/6.0, the DC-820B can control up to 8 devices through DC-820B’s BIOS, such as fixed disk and removable media devices.
To run the MCS ECU, type CF. Choose the DC-820B EISA SCSI Host Adapter to select the desired options. There are three fields providing as- sorted options for Hardware, Firmware, and SCSI devices. As for the AMI ECU, type CFG to set the options for Hardware and Firmware , and then run the utility ACF20SU.EXE for SCSI device option setting, if necessary.
