BusLogic BT-956C, User Manual

Testing Adapter Connectivity

Use the DMA 

 Port 

option on the AutoSCSI Diagnostics Menu to

test the adapter’s connectivity to the motherboard. This test writes and

reads data between the adapter and the motherboard.

1. Press 

Ctrl-B 

at 

the prompt that follows the system startup banner:

At the AutoSCSI main menu, use the arrow keys to select the Diagnos-

tics Menu and then select the 

DMA Test on IO Port 

option.

This DMA test checks the integrity of the adapter’s address and data

path during bus master operation. It writes data from the selected

adapter’s local memory to system memory, then reads the data back

and verifies its integrity. This test destroys system memory locations

from 6000:0 through 9000:FFFF.

You will see a display similar to the following during testing:

Testing DMA in memory range (Segment:Offset)

Performing Walking l’s and O’s on 

Test Loop: 2

The display has a counter indicating the memory locations as they are be-

ing tested and the number of test loops completed. If the test fails, 

SI shows the failing address value. For example:

DMA test failed at the above address.

In case of a failure, refer to your adapter hardware set up instructions.

A failure most likely indicates that there is a problem in the configura-

tion between the host system and the adapter.

3. Press 

 to abort this test.

Hard Drive Setup

Before you can install any software on the hard drive, you will need to en-

sure that your hard drive has been low-level formatted. Most off-the-shelf

hard drives are already formatted. If this is not the case, or your drive re-

quires a low-level format as indicated by error conditions, use the low-lev-

el format utility included with the 

 AutoSCSI utility (Section 4).

Proceed to Section 3 for AutoSCSI configuration.

If multiple adapters are installed, the utility will first prompt you to se-

lect the desired adapter.
