Cache DRAM test: Suppressed/Simplified/Full test. Suppressed test is the
default option and would just skip the test on cache DRAM to save time for
system boot-up. Full test on cache DRAM includes regular pattern, random
pattern, and address pattern tests. Choosing the Simplified test option would
only activate the regular pattern test.
Host Adapter SCSI ID: 0-7. The default ID of DC-820B is 7. Each device,
including the DC-820B, must have its own individual SCSI ID. If any
conflict occurs, check the device menu for proper ID setting.
DOS 5 Support enable / disable: Under DOS environments, the devices
connected to the DC-820B can be controlled through BIOS INT 13H or
device drivers. There are some limitations for devices serviced by BIOS INT
13H, such as the I/O port has to be set as 330H and the SCSI ID must start
from 0. This option enables you to overcome the above limitations. Two
options available are as follows:
1).
Disabled (default)
When this option is chosen, you can only handle two drives through BIOS
INT 13H. Be sure that the SCSI IDs of these two drives must start from 0
and make sure to set 330H as your I/O port address. All other SCSI
devices, such as fixed disk (more than two), removable cartridge, re-writable
optical disk (MO), tape streamer, DAT, and CD-ROM, should be controlled
by device drivers.
When devices are under the control of BIOS INT 13H, IDE drives always
have higher priorities over SCSI drives. The following is an example describ-
ing all the combinations:
