SCOBTLD.EXE DOS Self-extracting Boot (BTLD) Diskette Image
SCOBTLD.Z UNIX Compressed Boot (BTLD) Diskette Image
To install the SCO ADV Driver you will need to create a
Boot Diskette containing the driver. You may create the diskette
using either a DOS or Unix system. Decide which system to use and
follow the directions below. After the diskette is created it can
be used to add the driver during an SCO OpenServer installation or
used to add the driver to an existing SCO OpenServer system.
Directions for both of these installation options are listed below.
Supported Adapters
==================
ABP940/ASB3940 UW Bus Master PCI ( Single Channel)
ASB3940 U2W Bus Master PCI ( Single Channel)
ABP950/ASB3950 UW Bus Master PCI ( Dual Channel)
ABP950/ASB3950 U2W Bus Master PCI ( Dual Channel)
ASB3950 U3W Bus Master PCI ( Dual Channel)
Instructions for creating the ADV Driver Diskette from DOS
==============================================================
The file scobtld.exe is a self-extracting archive which contains
an image of an SCO OpenServer EAFS file system. The image can be
copied to a 3.5" diskette to make an ADV Driver BTLD diskette.
1. Copy the file scobtld.exe from the AdvanSys DOS diskette
containing the directory SCO to a DOS system.
> copy a:\sco\scobtld.exe
2. Type the command scobtld.exe. The following two files will be
created:
btld.dat
unixfer.exe
3. Insert a blank formatted diskette in the 3.5" floppy disk drive
and create the diskette with the following command.
> unixfer btld.dat a:
4. To verify the contents of the diskette unixfer can also be run
in reverse. The file btld.dat should exactly match test.dat.
> unixfer a: test.dat
> fc btld.dat test.dat
Instructions for creating the ADV Driver Diskette from SCO
OpenServer
================================================================
The file scobtld.Z is a compressed image of an SCO OpenServer EAFS
file system. The image can be copied to a 3.5" diskette to make an
ADV Driver Diskette.
1. Copy the DOS file SCOBTLD.Z from the AdvanSys DOS diskette
containing the directory SCO to an SCO Unix system.
$ doscp a:/sco/scobtld.z scobtld.Z
2. Uncompress the file scobtld.Z with the following command.
$ uncompress scobtld.Z
3. Insert a blank diskette in the 3.5" floppy disk drive and use
"dd" to create the diskette with the following command.
$ dd if=scobtld of=/dev/rfd0 bs=64k
4. To verify the contents of the diskette run dd in reverse.
The file scobtld should exactly match test.dat.
$ dd if=/dev/rfd0 of=test.dat bs=64k
$ cmp scobtld test.dat
Installing the ADV Driver during SCO OpenServer Installation
=============================================================
1. Create an AdvanSys driver diskette as described above. Label
the diskette "AdvanSys SCO BTLD Diskette." Please also record
the version of the driver on the diskette. The driver version
number should be listed at the beginning of this file.
2. Set-up your devices to have the following SCSI Target IDs:
Hard Disk: 0, CD-ROM: 5, and Tape Drive: 2.
3. Boot the system with the SCO installation boot disk.
4. Type "link" at the boot prompt "Boot:". This will cause SCO
to dynamically link the AdvanSys driver into the install
kernel. The AdvanSys driver is a BTLD (Boot Time Loadable
Driver).
5. When the installation asks you what package to link, enter
"adv". This is the name of the AdvanSys BTLD driver package.
NOTE : When using both "asc" and "adv" drivers, type in
"asc" first. "asc" is the SCO-OpenServer driver for AdvanSys
Ultra/narrow SCSI adapters.
6. Insert the "AdvanSys SCO BTLD Diskette" into the floppy drive
when the system requests it. Note: The diskette should not be
inserted after entering "adv". The install procedure will ask
for it later.
7. The install procedure may ask for the "AdvanSys SCO BTLD
Diskette" more than once.
Installing the ADV Driver after SCO OpenServer has already been
Installed
=================================================================
1. Create an AdvanSys driver diskette ask described above. Label
the diskette "AdvanSys SCO BTLD Diskette." Please also record
the version of the driver on the diskette. The driver version
number should be listed at the beginning of this file.
2. Type the command "installpkg" from the SCO OpenServer command
line.
3. Insert the "AdvanSys SCO BTLD Diskette" into the floppy drive
when prompted.
4. After installation, type the following commands to rebuild a
new kernel that contains the adv driver. For more information
refer to the SCO documentation regarding compiling the kernel.
cd /etc/conf/cf.d
./link_unix
Installing SCSI Devices under SCO OpenServer
=======================================
To create device files to access SCSI devices use the SCO "mkdev"
command. "mkdev" is an interactive command that will ask you
questions about your SCSI configuration, make kernel configuration
changes, and re-build the kernel. Type "mkdev hd" for disks, "mkdev
tape" for tape drives, and "mkdev cdrom" for CD-ROM devices.
"mkdev" will ask the name of the AdvanSys driver and AdvanSys SCSI
adapter number. The driver name is "adv" and adapter numbering
begins with 0. If there is one AdvanSys adapter enter "0", a second
adapter is number "1", etc. For disk devices "mkdev hd" should be
run twice. The second time it is run after the kernel has been
re-built and booted so that the disk can be partitioned and file
systems can be built.
The "mkdev" kernel configuration file is /etc/conf/cf.d/mscsi. It
can be viewed with an editor to verify "mkdev" has added the
correct parameters to the kernel configuration.
Here is a basic list of SCO SCSI device files:
Disk Device Files: /dev/[r]dsk/[0-9]s[0-9]
Tape Device Files: /dev/[nruh]Stp[0-9]
CD-ROM Device Files: /dev/[r]cd[0-9]
Installation Problems and Troubleshooting
=========================================
Problem 1:
----------
The AdvanSys SCSI Host Adapter controls the boot disk.
When the system boots the following warning message is printed
and, the SCSI disk is NOT recognized.
WARNING: hd: no root disk controller
Resolution 1: Make sure that the SCSI Disk is at ID 0.
Resolution 2: When there are multiple HBAs installed ( AdvanSys or
from other vendors ), the root hard disk is expected to be on the
first of these HBAs as detected by the OS.
To change this default, enter the following string after "link"
at the "Boot:" prompt. ( Step 4 of Installation procedure)
defbootstr Sdsk=adv(ha_num, SCSI ID, 0)
Example : link defbootstr Sdsk=adv(1,0,0)
Note :
The ha_num can be found from the line printed by the AdvanSys
Driver.
%adv 0x6000-0x6040 11 0 AdvanSys U2W/UW SCSI 3.2B ha_num=0
%adv 0x6000-0x6040 13 0 AdvanSys U2W/UW SCSI 3.2B ha_num=1
. .
. .
%adv 0x6000-0x6040 15 0 AdvanSys U2W/UW SCSI 3.2B ha_num=n
Problem 2:
----------
The AdvanSys SCSI Host Adapter controls the boot disk.
When the system boots the following warning and panic messages
are printed:
WARNING: hd: no root disk controller
PANIC: srmountfun - Error 19 mounting rootdev (1/40)
Resolution 1: These error messages indicate that the AdvanSys driver
is not compiled into the SCO OpenServer kernel being booted or on
an initial installation the SCSI hard disk is not set to target
ID 0.
If you are performing a first time installation make sure that
your SCSI hard disk target ID is 0. This is an SCO OpenServer
requirement.
To recover if you have rebuilt the SCO OpenServer kernel and the
previous kernel worked with the AdvanSys adapter, then at the
boot prompt "Boot:" type "unix.old".
This will cause the last kernel to be booted ("unix.old") instead
of the currently installed kernel ("unix"). After restarting
the system, rebuild the SCO kernel to include the AdvanSys driver.
Problem 3:
----------
The CD-ROM drive is not being recognized by the OS and the
following error message is displayed :
NO RESPONSE : There is no response from the controller for the
device that you have selected.
Resolution 1 : Make sure that the SCSI ID correct.
Resolution 2 : Make sure that the SCSI Adapter type is adv.
Resolution 3 : Make sure that the SCSI Host Adapter is correct.
When there are multiple AdvanSys HBAs this will take values
0,1,2....
Resolution 4 : Restart the Installation procedure and change the
default CDROM settings as follows.
To change this default, enter the following string after "link"
at the "Boot:" prompt. ( Step 4 of Installation procedure)
defbootstr Srom=adv(ha_num, SCSI ID, 0)
Example : link defbootstr Srom=adv(1, 5 ,0)
Problem 5:
----------
During SCO OpenServer 5.0 installation the keyboard locks
up and does not accept any keyboard input.
Resolution : This is a known SCO OpenServer 5.0 problem on faster
systems with an AMI keyboard BIOS. SCO has a solution for the
problem available from their technical support. The problem
can be identified as OSS424A. Here is the FTP location of the
solution:
