Q. I have a SCSI Adapter or an IDE adapter and I am moving
my drive from another controller, It is not booting but
if I boot from a Diskette, I can see my drive.
A. Boot with a disk with FDISK on it and type:
A:>FDISK /MBR
Q. How can I improve on the Preformance of my SCSI Chain?
A. The preformance of the SCSI Chain is effected by
many Elements of the SCSI Chain including a
system component, a controller component, and a
system component. Let's explore each of the
system components:
1) System Component
Setting up the system bus to properly accept a BusLogic
controller is crittical to the speed of the SCSI Chain.
If you are using an ISA board make sure you are using the
maximum allowable bus speed that will work with your system.
The normal bus rate is 5.0Mhz but some systems permit up
to 8MHZ. Thsi setting will be set in your Main Board's
BIOS and in the toggle of BTDOSM.SYS in your CONFIG.SYS.
If you are using PCI or VL-BUS controller, make sure that
your controller is plugged into a Bus Master Slot, not all are.
Also, make sure that the Bus-Speed is correct.
2) Controller Component
For each of your high preformance devices, make sure that
Syncronous Support, FAST Support are turned on in AUTOSCSI
or by DIP switches. Make sure you load BTDOSM.SYS if under
DOS. Use the shortest cable possible and use active terminators.
Use high quality cables, shilded if external. Enable Disconnection
in AUTOSCSI. Verify that the system attributes (INT, PORT
address, BIOS) have UNIQUE values and are NOT shared. If a
drive was formatted on another brand of controller, back it up
and then delete the partition, recreate the partition, and restore
the data.
3) SCSI Device Component
The preformance of the slowest device on your SCSI Chain
will determine the speed of the chain. Do not mix SCSI-I
and SCSI-II devices if speed is an issue. Make sure that
each of your SCSI Devices is set properly, has updated
firmware, can support FAST and SYNCRONOUS Mode,
and if it uses an ASPI Driver, the current Driver as well
as current Firmware, BIOS, and Drivers for your BusLogic
adapter.
Q. I am running NetWare and I recieve a Lost Hardware Interput
Error?
A. This a passive error and can be corrected by adding the line:
SET DISPLAY LOST HDW INT ALEARTS=OFF
to your AUTOEXEC.NCF file.
Q. I have a Sound Board and a SCSI Controller and I am experiencing
Problems?
A. The MIDI Port Address is in conflict with your SCSI Card (Port
address 330h), so you need to change the port address on the
soundboard to 330h or lower. There may also be DMA conflicts
and Interpt conflicts.
Q. I have a 946C PCI SCSI Controller, and every time I load BTDOSM.SYS
my system hangs.
A. Verify the following:
1) The motherboard is a PCI 2.0 complient
motherboard and the jumpers on my card
are not jumperd. Or, my motherbard is not
PCI 2.0 complient and I have set the jumpers
to a free BIOS Address. Then, I try plugging
my PCI Card into the slot closest to the
power supply, go into AUTOSCSI and change
the Interupt to 15, and PIN Level to C.
2) My card is plugged into a PCI BusMastering Slot
3) I have Updated F/W and BIOS
4) I have downloaded the current version of my drivers
from the BusLogic BBS.
Q. Why does the "NO ROM BASIC" Message appear when Booting Up?
A. The Following reasons would account for the the "NO ROM BASIC"
include:
1) The SCSI Boot Drive is not on SCSI ID 0 or 1.
2) The Termination in the SCSI Bus is not propper and/or
an Active Terminator is needed.
3) The Boot Partition is not set to ACTIVE.
4) The SCSI BIOS is not active, or in multipal controller
configurations, more than one BIOS is active.
5) Interupt, Base Address, BIOS, or DMA conflict with another
controller in your system.
Q. Why is the Message "Missing Operating System" displayed durring
boot, but the hard drive is still seen by the controller.
A. You want to make sure that the Drive has an Operating System on the
Boot Drive. If under DOS, make sure the Drive is properly FDISKed
and FORMAT C:/S has been issued. If the OS is on the drive, you may
need to backup your data and delete all partitions on the disk and
recreate them.
Q. My System displays a HARD DISK FAILURE Message, what's wrong?
A. If you are using only SCSI, set CMOS Drive type to "NOT INSTALLED",
if you are mixing Drive types, set the SCSI Drive to NOT INSTALLED.
If you are using an BusLogic IDE Controller, set the drive type to 1 for
each of your IDE drives. If the message proceeded, check all controller
settings as discribed in your manual. Then, replace the data cable and
the the power supply voltage Levels. Lastly, the drive mak be defective
or in the case of IDE, the Master & Slave settings may be wrong.
Q. My SCSI Bus Scan shows 6 Devices and I only have one, what's wrong?
A. The termination on the bus is not proper or the data cable is defective or
too long or the device is on ID 7 ( The default for the controller).
Q. What do I need to use a SCSI CD-ROM under DOS:
A. Make sure your CD-ROM is on SCSI ID 2-6 and add the following to the
begining of your CONFIG.SYS:
DEVICE=C:\BUSLOGIC\BTDOSM.SYS /D /M
DEVICE=C:\BUSLOGIC\CDROM.SYS /D:MSCD002
Add the following to your AUTOEXEC.BAT:
C:\DOS\MSCDEX /D:MSCD002 /M:10
Q. How do I get non-Hard Drive SCSI Device to work with my system?
A. Remember 0,1, and 7 are reserved, so place your device on 2-6.
The Load the Following at the begining of your CONFIG.SYS:
DEVICE=C:\BUSLOGIC\BTDOSM.SYS /D /M
Then after BTDOSM.SYS, the ASPI Manager, loads, you will need an ASPI
Device Driver for your Device. This is provided by the device Mfg. or
in third party drivers kits such as Corel SCSI.
Q. I have more than 2 Disks on my SCSI Controller or my SCSI BIOS is
Disabled or I have more than one BusLogic SCSI Controller or my device
is a Removable Media Device (Like SYQUEST), how do I Access them?
A. In your CONFIG.SYS, load the following:
DEVICE=C:\BUSLOGIC\BTDOSM.SYS /D /M
DEVICE=C:\BUSLOGIC\BTMDISK.SYS
Then use BTFDISK to Partition the disk and DOS FORMAT to high level
format the Disk(s). (You will not beable to boot off of these drives if your
BIOS is disabled)
Q. Can I connect SCSI-I, SCSI-I CCS, and SCSI-II devices to my BusLogic
Controller?
A. Yes.
Q. How can I Maximize my Disk throughput?
A. 1) Use a Short, High Quality Cable.
2) If using an external uint, use an ACTIVE TERMINATOR
3) Enable Synchronous Mode on controller and device.
4) Enable FAST Mode on controller and device.
5) Remove SCSI-I devices.
6) Load BTDOSM.SYS if Under DOS.
Q. I can Only See 528 MB on my IDE Controller and my drive is >528MB.
A. In Disk Parameter Setup in AutoIDE (F2 or F6 on bootup), go to TRK REMAP
on the >528MB Disk Drive and enable it. Then, delete and recreate the
partion table using FDISK.
Q. Can I use DISK MANAGER with my BusLogic IDE Drive?
A. No, you simply turn TRK REMAP in AutoIDE to ENABLED
to access >528MB.
Q. I am using DOS and a BusLogic Adapter, what device drivers do I
need to Load?
A. You need to put the following at the begining of your CONFIG.SYS:
DEVICE=C:\BUSLOGIC\BTDOSM.SYS /D /M
No other drivers are needed, you will need APSI-aware tape
backup software to access the tape drive.
Q. Under Which operating systems do I enable >1GB Option on my
BusLogic Adapter.
A. Operating System Enabled?
DOS Yes
NetWare No
UNIX No
NT Yes
Q. I am connecting a Floppy Tape Drive to my SCSI Adapter,
and the Preformance is slow. How do I speed this up?
A. Add the toggle /n04 to BTDOSM.SYS
Q. How do I find the current version of Firmware and BIOS in my Adapter?
A. Call BusLogic Tech Support and ask the operator what the
current BIOS and F/W Level is current. You will need to know
the BusLogic Controller Model # and Board REV Level.
Q. I have a Sound Board and a BusLogic SCSI Adapter in my system, are
there any conflicts.
A. Yes. Interupt Conflict (Card Default is 11)
MIDI Port Address Conflict (Default is 330)
DMA Conflict (Default is 5)
Q. What kind of Memory do I need for my BusLogic IDE Controller?
A. You need 80ns or Faster, 1x9 SIMMS (9 Chip).
Q. I have a BusLogic SCSI Controller and a Hard Disk on not on
ID 0 or 1 and I cant see it.
A. To see the drive without driver or to boot on the drive, the drive
must be on ID 0 or 1, else you must load BTDOSM.SYS and
BTMDISK.SYS, and use BTFDISK to partition the drive.
Q. I am using ARCSERVE/ARCSOLO and Netware and my system is
locking up?
A. Specify the NOSCAN option in the Netware Driver.
Q. I am trying to partition my Hard Drive with >2GB and FDSIK
and it doesn't work?
A. DOS FDISK has a partition size limit of 4 drives by 2GB each drive.
To get larger partition sizes, load BTDOSM.SYS and use BTFDISK
to partition the drive and DOS' FORMAT to high level format the
Partition.
Q. I am using BSD UNIX and I have a driver problem.
A. Please contact Berkley Systems Drirectly for Driver
Support.
