TITLE: OpenVMS ALPDRIV10_071 Alpha V7.1 - V7.1-1H2 on DPWS ECO Summary
Modification Date: 04-FEB-99
Modification Type: DOCUMENTATION: Corrected Typographical Error
Updated Kit: Supersedes ALPDRIV07_071
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for OpenVMS Alpha V7.1 through V7.1-1H2 on OpenVMS
Alpha V7.1 through V7.1-1H2.
Problems addressed in the ALPDRIV10_071 kit:
o The new version of the DQDRIVER now provides support for the
Iomega ATAPI Zip drive. This drive allows use of the same
100MB Iomega Zip diskettes that are widely used as a backup
and transport media for personal computers and allows easy
data interchange with these systems.
The particular drives supported are Iomega part numbers
270928-003 (with a beige bezel) and 270928-703 (with a frost
white bezel). These drives are available from Compaq Computer
Corporation and contain firmware version "12.A".
o ATAPI discs, that had a maximum Logical Block Number (LBN) of
0x...1FF, were sized 0x100 2K blocks (1024 512-byte blocks)
too small.
o An ATAPI drive request to transfer an invalid amount of data
could possibly cause an allocated buffer to be overrun.
o The system hung when trying to load the SYSINIT.EXE image.
o During packack, a second command could be issued to a drive
while the first command was still executing.
o Support for the Compaq/Panasonic SR8583 was added.
o The device timeout was changed to 15 seconds to accommodate
the Toshiba XM-6302B CD-ROM drive.
o Autoconfiguring of the DQDRIVER was fixed so that either
autoconfiguration or a manual, explicit ISA bus I/O address
is accepted.
o A "can not mount ISO 9660 volume" error occurred so a change
was necessary for ISO-9660 (F11CACP) and High Sierra (F11DACP)
support.
NEW FUNCTIONALITY INTRODUCED IN ALPDRIV07_071 KIT
o OpenVMS IDE (ATAPI) CD-ROM Device Driver
DIGITAL is pleased to introduce the OpenVMS IDE (ATAPI) CD-ROM
Device Driver Kit for use with Digital Personal WorkStations (DPWS)
433au, 500au, and 600au systems. This software allows DIGITAL
OpenVMS customers to install OpenVMS Alpha Version 7.1-1H2 software
using the IDE (ATAPI) CD-ROM drives on DPWS 433au, 500au, and 600au
systems. In addition, this diskette contains a command procedure
to install additional software on system disks.
+ Most modern ATA/IDE/EIDE controllers implement two busses:
a primary bus and a secondary bus. You can attach up to two
units to each of these busses. The two units are known (for
historical reasons) as the Master and Slave units. This allows
a total of up to four units to be attached to most current
ATA/IDE/EIDE controllers.
OpenVMS software and the Console firmware implement the following
device naming conventions:
Device | |
Name | Bus | Unit
----------+-----------+--------
| |
DQA0: | Primary | Master
DQA1: | Primary | Slave
| |
DQB0: | Secondary | Master
Known Restrictions:
o If the IDE CD-ROM driver fails to install or configure properly,
please contact your DIGITAL customer representative to ensure that
your system hardware and firmware are up-to-date.
To check to see whether your system is current, do the following:
+ At the console prompt enter the following command:
>>>SHOW CONFIG
+ Your firmware is up-to-date and current with this driver
if the following revision information (or later) is displayed:
Firmware
SRM Console: V6.7-195
ARC Console: 5.65
PALcode: VMS PALcode V1.20-13, OSF PALcode V1.22-14
SROM Version: V5.15
+ Your hardware is current and compatible with this driver if
your device is shown as:
Bus 00 Slot 07: Cypress PCI Peripheral Controller
o When you boot using the OpenVMS IDE CD-ROM Device Driver Diskette,
the system displays a message that the SYS$CPU_ROUTINES are being
loaded from the secondary boot device (the diskette). A second
informational message is then displayed stating that the system
is unable to locate the CPU routines. For example:
Loading SYS$CPU_ROUTINES_1E05.EXE from the Secondary Boot Media.
%SYSBOOT-I-FILENOTLOC, Unable to locate SYS$CPU_ROUTINES_1E05.EXE
Disregard this informational error message. The system will load
the CPU routines from the primary boot device (the CD-ROM).
o If you boot an ATAPI device (for example, DQB0:), any other unit on
the same IDE bus (for example, DQB1:) will not be available. Units
on the alternate IDE bus (for example, DQA0: and DQA1:) will be
available.
o Supported CD-ROM Drives
The IDE CD-ROM Device Driver should work with a wide range of IDE
(ATAPI) CD-ROM drives. The following CD-ROM drives have been
tested by OpenVMS Engineering. Refer to the "Systems and Options
Catalog" for the supported drives.
+ Sony CDU711 CD-ROM
+ Toshiba XM-5702B 12x CD-ROM
+ Toshiba XM-6202B 32x CD-ROM
+ Toshiba SD-M1102 DVD-ROM (as a 24x CD-ROM drive)
o Console Environmental Variable os_type Set to OpenVMS
The console supports both the OpenVMS and Digital UNIX platforms.
The Console Environmental Variable os_type must be set to OpenVMS
in order for the console to display the correct device name for the
IDE CD-ROM driver. To ensure that the Environmental Variable
os_type has been set to OpenVMS, enter the following command:
>>>show os_type
If the Console Environmental Variable os_type displays as UNIX,
enter the following commands:
>>>set os_type OpenVMS
>>>show os_type
The Console Environmental Variable os_type should now display as
OpenVMS.
o Audio Features
This version of the IDE CD-ROM Device Driver does not support
playing audio (CD-DA) disks. Support will be added in a future
release.
o DVD Media
This version of the OpenVMS IDE CD-ROM Device Driver is capable
of reading DVD-ROM disks. This allows the mounting of a DVD-ROM
disk written with ISO-9660 formatting. However, as of this release,
OpenVMS does not support the UDF or Micro UDF (DVD-ROM standard)
file formats.
+ Restriction with DVD Media
After a CD-ROM or DVD-ROM disk has been mounted, you can use
the $SHOW DEVICE/FULL command to show the total number of
OpenVMS 512-byte blocks stored on the disk. This command
also shows a number of cylinders, tracks, and sectors on
the disk. For a CD-ROM or DVD-ROM device, these numbers
are synthesized based on the number of blocks on thedisk.
For DVD-ROM disks with more than 2,097,152 512-byte blocks
(about 1.05 GB), the number of cylinders reported will be
incorrect (truncated to 16 bits).
o Magnetic Disk Drives Not Supported
Although the IDE CD-ROM Driver is also capable of controlling
industry-standard ATA/IDE/EIDE magnetic disk drives, this is
presently unsupported in this version of the driver. In
particular, this version of the IDE CD-ROM Device Driver
does not implement Direct Memory Access (DMA) and, therefore,
magnetic disks will not achieve the full performance possible.
o Problem with Initializing Some Magnetic Disks
Some magnetic disks come pre-written with a data pattern that
contains all '1's in the last block (and a particular byte
in the last block). OpenVMS software interpets this pattern
as an indication that the disk is an ancient "diagnostic
pack", that is, a bad-block-free pack. OpenVMS will not
initialize these disks. You can restore a backup onto these
disks, even though you will still receive the warning.
You can also use the WRITE_PBLK physical I/O function to
over-write the last sector on the disk with a different data
pattern. Note that the address passed to WRITE_PBLK is *NOT*
an LBN; rather, it is in the form of cylinder, head, and sector.
See the "I/O User's Guide" for further information.
