QUANTUM   ATLAS I/II TIPS

 =====================================================================
 Application Note
 INSTALLING ATLAS II DRIVES ON A DIGITAL SYSTEM

 Digital System               DEC UNIX/DEC OSF rev 3.2 or later
 -------------------------------------------------------------------
 This application note is to be used only as a guideline for the
 titled subject. The user assumes all responsibility for understanding

 the interrelationships of this information with other affected
 software or system products. Quantum Corporation provides this
 information as a service only, and assumes no responsibility for
 any damages which could result from the use of this information.

 The information in this application note is subject to change
 without notice and is not to be construed as a commitment by
 Quantum Corporation. Quantum Corporation assumes no responsibility
 for any errors that may appear in this document.

 This application note provides instructions for installing the Atlas
 II family of disk drive products on a Digital system running DEC UNIX

 / DEC OSF rev 3.2 or later.

 Note: Before placing any Atlas II drive on any of the following:

  KZPSA (Wide Differential PCI Slot Controller) or
  KZPSA (Wide Differential PCI Slot Controller)

 Set the Always Save Data Pointers (AlwaysSDP) bit. This bit is
 located in Mode Page 25h/Byte 2/Bit 7. Normally Byte 2 is set to
 00hex. To set the Always SDP bit, this must be changed to 80hex.

 - Adaptec 1740 Controller, usually found in the DEC PC AXP 150
   (Jensen)

 Set the Delay ESP (DlyESP) bit. This bit is located in Mode Page
 25h/Byte 5/Bit 3. Normally, Byte 5 is set to 00hex. To set the
 DlyESP bit this must be changed to 08hex.

 DRIVE INSTALLATION PROCEDURE
 1. Connect drive on the bus (keeping in mind not to conflict id).
    For this example, let's assume the Atlas II drive is at id1,
    system disk is at id0, host is at id7, and the bus is BUS 0.

 2. Type "show config" at the console level before the system
    comes up. The user should see all devices on all buses. If
    the device is on a Turbo Channel slot (for example, tc1),
    then the user must type "t tc1 confg" to see the devices on
    that bus. (Please refer to your Hardware Configuration Guide
    for any questions related to console commands.)

 3. After booting the system, type the following in any shell window:

    scu sho edt | grep "Direct Access"

 The "scu" command will show all available drives and CD-ROM on the
 system with their respective bus and ID number. It is important to
 note bus type, 8-bit or Wide, and target id of the drive.


 4. Then type
    file /dev/rrz*c

 This should also give a list of device files that each drive and/or
 CD-ROM is using; e.g., bus 0 ID 0 is /dev/rrz0c, bus 0 ID 1 is /dev/
 rrzlc. Rule of thumb: Devices files are numbered from rz0 - rz7 for
 all ids numbered on an 8-bit single-ended bus 0; from 8 - 15 for ids
 on an 8-bit single-ended bus 1, and so on_, e.g., bus 1 id 0 is rz8.
 If you don't have a device file for the drive, refer to the System
 Administration guide and the man pages on MAKEDEV to determine
 options. Typically, sysadmin will have to "cd /dev" then execute
 "./MAKEDEV rz#" to create the missing device files. For wide
 drives, the steps are the same except device files are 16 per
 bus; i.e., rz0 through rz15 for a wide bus 0.

 5. Once the device file has been identified (e.g., for bus 0 ID1,
    it would be /dev/rrz1c), type one of the following drive models:

    disklabel -rw rzl xp39100 - for 9GB, or
    disklabel -rw rz1 xp34550 - for 4GB, or
    disklabel - rw rz1 xp32275 - for 2GB

 At that point, the drive is ready to be used with the system.
 Type disklabel -r rz1 (to see the partition label of the drive).
 To set up the drive in any other way other than the standard
 disklabel, refer to the System Administrator's Guide and the man
 pages on disklabel to determine options.

 DRIVE INSTALLATION PROCEDURE
 1. Connect drive on the bus (keeping in mind not to conflict id). For
    this example, let's assume the Atlas II drive is at id1, system
    disk is at id0, host is at id7, and the bus is BUS 0.

 2. Type "show config" at the console level before system comes up.
    The user should see all devices on all buses. If the device is on
    a Turbo Channel slot (for example, tc1), then the user must type
    "t tc1 confg" to see the devices on that bus. (Please refer to
    your Hardware Configuration Guide for any questions related to
    console commands.)

 3. Boot system and the drive will be recognized. It is up to the user

    at that point to make sure that the necessary steps are completed
    to make the drive useful in Windows NT, i.e., formatting,
    partitioning, etc.

 AHA 154x, 174x and possibly some newer models:
 There is a timing issue in that old Adaptec host adapters cannot work
 at the full speed of the Atlas (specifically, hardware read cache
 hits in the drive are handled too quickly and the host adapter isn't
 ready for data when the drive starts to send, so bytes get lost.)

 Fix: Use DSP tools (PUBLIC\TOOLS\DSP) to set the ESPDLY bit in mode
 page 25h. How: See ESPDLY.TXT.

 AHA 2940UW:
 Installing NT4.0 over an AHA-2940UW onto an Atlas with XL912 may not
 work. We are also getting reports of XL912 not working up to par on
 other systems. Vcommunications, for example, is requiring XL915 for
 their System Commander software.

 In response to this, DSE techs have been informed as to how to
 identify Atlas module types and firmware revisions, and have been
 instructed to upgrade anyone with XL912 to XL915. The required
 upgrade materials (FW, DSPTools, instructions) can be found on our
 BBS in the XL915 library, on our FTP site at ftp.qntm.com/pub/
 Support/Firmware/Atlas, and by email per request.

 We stand firm that Quantum offers no service or support for customers
 who opt to upgrade their firmware without first consulting a
 qualified technician. The technician shall judge the technical
 ability of the customer before offering DSP Tools, and may work with
 the product specialist to have the drive sent to Quantum for a FW
 upgrade.

 There are two different hardware versions for wide drives, type 22962
 and type 60059. They can be distinguished via a different secondary
 option connector (the one at the back between the two LEDs.)
 Type 22962 has a 14-pin option connector, 60059 has 12 pins. Use
 firmware A?W14*.FUP for module type 60059, A?WXL*.FUP for all others.

 Adaptec 1740 adapter: System hangs during DOS installation

 Following a successful DOS format, the DOS installation starts,
 the system hangs, and the drive's green Busy LED stays on.
 This issue has also been found on the DECpc AXP 150 system running an
 Adaptec 1740 adapter.

 A feature called ESP_Delay was added on Atlas I drives to work around
 a problem with some Adaptec adapters (1740, 1540). The Atlas I was a
 little too fast for the Adaptec adapter and we, therefore, added the
 ESP_Delay via a mode page bit.

 We found that the ESP_Delay time was incorrectly set as we increased
 the clock speed on Atlas II. This issue was found on the DECpc AXP
 150 system running an Adaptec 1740 adapter.

 Firmware version XLXQ1 only increases the delay time. We will still
 be shipping into distribution with ESP_Delay off. If a customer has a
 problem with the adapter, we will supply the tool to turn on
 ESP_Delay instead of loading new firmware.

 Adaptec SCSI PCI Ultra 2940U/UW adapter: Serious disk errors under
 DOS Xcopy

 While running DOS Xcopy (especially with the large files - 1 to 2 MB
 in size), the system reports a serious disk error has occurred while
 writing to the drive.
 This issue occurs on the Adaptec 2940 U/UW with Bios version 1.21.

 Adaptec upgraded the Bios on SCSI PCI Ultra 2940U/UW adapter to
 version 1.23
 Therefore, this issue should be resolved with Adapter 2940U/UW Bios
 versions 1.23 or higher.
 =====================================================================

 Setting the ESPDLY bit with DSP tools (for Atlas and Atlas II drives)

 Start DSP tools. If it doesn't seem to do anything, check ERROR.LOG.
 DSP tools supports a mouse if a DOS mouse driver is present.

 Read the disclaimer.

 Setup/Select/select drive ID/Ok.
 Setup/Protection/turn off/Ok.

 Mode Page/Edit/Generic Page viewer/Page 25 (no 0x or h please)
 Set Bit 3 of byte 5 in page 25. Byte 0 is where the a5 byte is:
