Step 2. Setting the SCSI Device ID
Each SCSI device must be assigned a unique SCSI ID
ranging from 0 through 7. Most SCSI peripheral devic-
es are shipped with a pre-assigned SCSI ID. Your Bus-
Logic adapter is set to SCSI ID 7 by default.
Note: The SCSI ID for your boot drive must be lower thn
other drives. BIOS scans from ID 0 to find the boot drive.
If needed, change the SCSI ID for the peripheral devic-
es as recommended in the owner’s manual. The only
time you may need to change the adapter ID is when
multiple adapters share a common SCSI bus (see the
AutoSCSITM Host Adapter SCSI ID option (Step 7)).
Step 3. Terminating SCSI Devices
The first and last SCSI devices connected together on a
SCSI bus must have terminators installed or enabled.
Terminators, which can be connected to either SCSI de-
vices or SCSI cables, are required for reliable operation
of the SCSI bus.
If more than two SCSI devices axe connected in a SCSI
daisy chain, you must remove/disable the terminators
on the middle device(s).
If the BT-54XC is not being installed at either end of the
SCSI bus, disable its terminators by using the Adapter
SCSI Terminators ON option on the AutoSCSI Configu-
ration Menu (see Step 7).
Step 4. Configuring Switch Settings
Before installing the adapter, check the switch settings
to verify that the default settings for BIOS Address and
Port Address do not conflict with other installed cards.

Figure 3. BT-54XC Switch Detail
The I/O Port Address must be unique. The adapter
is factory-shipped with Port Address 330. Check for
conflicts with other cards.
One card in the system must have BIOS enabled. by
default the BT+IXC’s BIOS is enableri at address
DCOOOH. If unavailable, change to one of the other
addresses listed in the table below.
Switch 8 enables/disables the floppy connector on
the BT-545C. Switch 8 is ON (enabled) by default.

Step 5. Installing and Cabling the Adapter
Remove the mounting screw and the existing
bracket from the rear panel behind the 16-bit slot
where you want to install the BT-54XC.
Ikss the BT-54XC downward into the se&ted 16-
bit slot, align the mounting bracket, and reinstall
the mounting screw. Make sure that the board is
properly seated in the slot.
Connect the 50-pin SCSI cable to the adapter’s sin-
gle-ended SCSI connector attaching the other end to
the SCSl device connector. Before plugging in cable
connectors, check that the “v” mark molded on the
connector or the colored stripe on the cable (indicat-
ing the location of Pin 1) matches Pin I of thti con-
nector on the BT-54XC.
If connecting to a floppy drive, insert the Wpin
floppy cable from the floppy drive into the floppy
connector (BT-545C only).

Host Adapter SCSI Terminators ON. Use this option
to set adapter SCSI termination. Only terminators on
devices at both ends of the SCSI chain should be turn4
on. (Def=Yes)
Device Configuration
Enable Fast Transfer (10MByte). Many devices arc ca-
pable of transferring data across the SCSI bus at 5 to 10
MBytes/set. This option can increase performance in
some applications if the attached device can also sup-
port the faster 10 MBytc/scc data rate. Used together
with the En&e Sync Ne,@iation option. (Def=Yes)
Enable Sync Negotiation. U SC this option to enable the
adapter to initiate the synchronous data transfer ncgo-
tiation bctwccn itself and each SCSI dcvicc connected
to the SCSI bus. (Def=Yes)
Enable Disconnection. Use this option to enable or dis-
able SCSI disconnection on each target device. When
enabled, it allows SCSI devices to perform seek opera-
tions in parallcl and thus improvcovcrall SCSI bus pcr-
formance. (Drf=Yrs)
BIOS Sends Start Unit Command. This option allows
you to specify the SCSI dcviccs whose motor spin up is
sequentially controlllti by BIOS at power-up. (Def=No)
Ignore in BIOS Scan. This option lets you exclude SC’-
lcctcd drives from BIOS scan and registration. (Def=No)
Advanced Configuration
Host Adapter BIOS Enabled. This read-only field dis-
plays whether BIOS is enabled or disabled for this
adapter.
Host Adapter BIOS Uses INT 19 for System Boot.This
option allows you to include or exclude the adapter on-
board BIOS in the DOS boot process. (Def=Yes)
Host Adapter BIOS Supports DOS Space > 1GB. This
option cnablcs the adapter onboard BIOS to support up
to 8 Gigabytcs per drive of DOS disk space. The > 7
CByte support must be turned on under the following two
conditions: (1) the combined space of all the DOS parti-
tions exceeds 1 GByte or (2) > 1 GByte disk accesses are
required to boot the operating system. (Def=No)
BIOS Supports Removable Disks as Fixed Disks. This
option enables the adapter BIOS to register removable
disks as fixed disks and access them via Interrupt 13H.
(Def=No)
BIOS Supports > 2 Drives (DOS 5.0 or Above). This
option turns on BIOS support for more than two hard
disk devices on the SCSI bus. (Def=Yes)
Enable BIOS Interrupt Mode. Enable if your version
of DOS is multitasking (e.g., PC-MOS). (Def=Yes)
Support Floptical Drive. When this option is enabled,
BIOS registers and controls floptical devices. (Def=No)
Enable SCSI Bus Reset. When this option is cnablcd,
the adapter asserts a SCSI bus reset signal upon dctcct-
ing a hard reset. (Def=Yes)
Resewed RAM for BIOS access (Segment: Offset) 0.
U SC this option to allocate system memory for BIOS p”-
ramcter storage. (Def=XXI)
Set Host Adapter I/O Port Address as Default. This
option is always enabled for this product.
Step 8. Testing Adapter Connectivity
Use the DMA Test on l/O Port option on the AutoSCSI
Diagnostics Menu to test adapter connectivity to the
motherboard. This test writes and rads data bctwccn
the adapter and the motherboard. Press <ESC> to end
the test. If the test fails, check your cable connections.
Step 9. Formatting the Hard Drive
Because most off-the-shelf hard drives are factory for-
matted, it is unlikely that you need to perform this pn)-
cedurc and you may proceed to Step 10. If, however,
you have an un-formatted disk, or if you arc expcricnc-
ing problems with your hard drive that indicate the
need for a low-level format, use the Format Disk option
on the AutoSCSI Utilities Menu.
Caution: This procedure will eruse everything on your
drive. Hack up your hard drive before proceeding.
The format duration dcpcnds on the size of your hard
drive. You cannot stop the format once it’s started.
Once it is completed, you may run the Verify Disk op-
tion to check the format.
Step 10. Setting Up the Hard Drive
You will need to take the following steps to configure
your hard drive for operation:
n Create a partition on the drive for your operating
system and high-level format the drive.
7 8

n Install the operating system.
These procedures differ depending on the operating
system you are installing. Refer to your operating sys-
tem documentation for details.
Step 11. installing the Device Driver
Device drivers arc necdcd to allow devices attached to
the adapter to be recognized by and operate with the
operating systcm.Whcrc the operating system has cm-
bedded support, you can install up to a specific numbcsr
of hard drives without ncxcding additional softwarcb.
For cxamplc, drivers supporting BusLogic SCSI hoht
adapters arc embedded in NctWarc ~3.12 and 4.X.
You will need to install drivclrs when going beyond
built-in support or whc>n installing dcsvicc>s such as C’D-
ROM or tape backup drivc>s, cbtc.
When you install BusLogic dcGcc, drivc\rs, you 1~111
have support for:
m Up to three BusLogic host ,ldaptcrs
n Up to seven SCSI pcriphc>r,ll dc)viccsh (hard drive>,
etc.) per host adapter
m Connectivity to SCSI CD-KOM drives, photo C’Dh,
tape drives, magneto optic,)] (MO) disk drives and
other devices.
DOS and NetWare Driver Installation

If you have not already done so, insert the floppy
diskette containing the DOS and NetWare drivers
into the floppy drive. If the driver floppy is in
Drive A:, cntcr: a: install
You arc promptcul to indic‘ttc the drive containin);
the floppy or press <ENTER> to dcccpt the default.
You are next prompted to scloct the> installation
method:
-
If you select Express, the DOS drivers will be in-
stalled automatically.
-
If you select Custom, you will be prompted to
specify the DOS or NetWare drivers to be in-
stalled.
The next step depends on which drivers you’re in-
stalling.
BusLogic DOS Driver Installation:
You will be asked if you want the utility to automat-
ically update your system CONFIGSYS and AU-
TOEXEC.BAT files. If Yes, the system updates the
DOS configuration files and renames your old files
to CONFIG.BL and AUTOEXEC.BL. If No, you will
have to update your DOS configuration files manu-
ally. Proceed to Step 5.
BusLogic Net Ware Driver Installations:
-
If you are installing update drivers for NetWare
3.11, installation is complete. Proceed to Step 5.
-
If you are installing the NetWare 3.11 operating
system for the first time, you will need to contin-
ue with operating system installation. See the
SCSl Adapter Driver Software Installation Guide for
further details. Proceed to Step 5.
_
If you are installing update drivers for NetWare
3.12 or 4.X, driver installation will be complete
after you modify your STARTUP.NCF file to re-
flect the new driver names as indicated in the
message screen. Proceed to Step 5.
5. Once installation is complete, re-boot your system
to activate the new device drivers. You won’t be
able to access the new devices until you do so.
Refer to the BusLogic SCSI Adapter Driver Software In-
stallation Guide or third-party documentation for device
driver installation details.
Troubleshooting
Review installation steps for correct procedure.
Be sure all connectors are firmly seated.
Check cable orientation. Be sure that Pin 1 on the ca-
ble matches Pin1 on the SCSI device connector.
Be sure that you‘ve followed termination rules. If
the BT-54XC is in the middle of the SCSI chain, use
AutoSCSI to disable termination.
Check that you have correctly set the hard drive op-
tion to not installed in the system SETUP file.
Be sure that settings for the adapter I/O Port Ad-
dress, BIOS Address, IRQ and DMA Channel do not
conflict with those of other installed cards.
If you changed any parameters using AutoSCSI, use
the AutoCon& All Adapters option to return the
board to factory defaults.

n If necessary, repeat the steps to format, partition
and install the operating system on the hard drive.
Be sure to backup the drive before proceeding.
