DESCRIPTION
___________
This README file contains important information on the usage and
installation of the Portable CD-ROM Driver version P2.0. This DOS
device driver is used to access the CD-ROM drive in a Compaq notebook
PC. If the notebook supports MultiBay devices, the driver offers the
Hot and Warm MultiBay Device Exchange feature under the DOS and
Windows 3.1 environments. Hot MultiBay Device Exchange is the
swapping of a CD-ROM drive, diskette drive and battery while the
notebook in ON and undocked. Warm MultiBay Exchange is the swapping
of a CD-ROM drive, diskette drive and battery while the notebook is
in suspend mode and undocked.
INSTALLING THE DRIVER
_____________________
To install the device driver,
1. At the DOS prompt (C:\), type
A:\CPQINST
2. When installation is complete, this README file is displayed.
3. Restart the notebook so the changes take effect.
ENABLING THE HOT /WARM MULTIBAY DEVICE EXCHANGE FEATURE
_______________________________________________________
To enable the Standby/Suspend device exchange features of the driver,
edit the CONFIG.SYS file in the following manner:
1. At the DOS prompt (C:\), type
EDIT CONFIG.SYS
2. To the line
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /D:IDECD001
add the /W switch so the line reads
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /W /D:IDECD001
3. Save and close the CONFIG.SYS file.
4. Restart the notebook so the changes take effect.
The driver behaves differently depending upon the computer as
follows:
USAGE OF DRIVER ON THE COMPAQ ARMADA 4100 SERIES
________________________________________________
This series support Warm Docking to the Mobile Expansion CD Unit (MCD).
To enable the Warm Docking capability, follow the procedure above to
enable the Hot/Warm MultiBay device exchange feature. Once enabled,
start the Armada notebook undocked, suspend the unit by pressing the
Suspend button, Place the notebook on the MCD, the CD-ROM of the MCD
is accessible.
DRIVER ON THE COMPAQ ARMADA 7000 SERIES
_______________________________________
This series support Hot and Warm MultiBay Device Exchange.
To enable the Hot or Warm MultiBay device exchange features of the
driver, edit the CONFIG.SYS file in the following manner:
1. At the DOS prompt (C:\), type
EDIT CONFIG.SYS
2. To the line
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /D:IDECD001
add the /W switch so the line reads
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /W /D:IDECD001
3. Save and close the CONFIG.SYS file.
4. Restart the notebook so the changes take effect.
USAGE OF DRIVER ON THE COMPAQ LTE 5000 SERIES
_____________________________________________
This series supports only Warm MultiBay Device support. The user
starts the notebook with a diskette drive in the notebook MultiBay
and the diskette drive is accessible. The user can then place the
notebook into Suspend by pressing the Suspend button, remove the
MultiBay diskette drive and insert either a CD-ROM drive or a
battery. If a CD-ROM drive is installed, it is accessible upon
exiting Suspend mode. When a battery is installed, the noteboook
recognizes the second battery as a power source.
To enable the Warm MultiBay Device Exchange feature of the driver,
edit the CONFIG.SYS file in the following manner:
1. At the DOS prompt (C:\), type
EDIT CONFIG.SYS
2. To the line
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /D:IDECD001
add the /W switch so the line reads
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /W /D:IDECD001
3. Save and close the CONFIG.SYS file.
4. Restart the notebook so the changes take effect.
Notes on the COMPAQ LTE 5000 SERIES:
___________________________________
1) This driver does not support audio on 2X CD-ROM drives with
Compaq spare part number 213561-001 (see barcode label on the
bottom of the CD-ROM drive). For audio support on these CD-ROM
drives, please use the Teac TEAC_CDI.SYS driver instead of
CPQLTECD.SYS.
Edit the CONFIG.SYS file line
DEVICEHIGH=C:\CPQDOS\CPQLTECD.SYS /D:IDECD001
so it reads
DEVICEHIGH=C:\AUDIO_CD\TEAC_CDI.SYS /D:IDECD001
2) When the notebook is docked in the MultiBay Expansion Base, the
Suspend device exchange feature is automatically disabled.
3) When the notebook is undocked, the driver prevents access to
drive B:. If you attemp to access drive B: (read, write or copy),
the message "Invalid media type reading drive B:." is displayed.
If you attempt to access Drive B: while in Windows 3.1 File
Manager, the message "Drive B does not exist" is displayed.
4) The A:, B: and CD-ROM drive letter icons are displayed in
Windows 3.1 File Manager. However, only the device present in
the notebook MultiBay can be accessed. If you select the B:
icon, the message "Drive B does not exist" is displayed.
5) Before removing the CD-ROM drive from the notebook, close all
applications (such as the Compaq Sound System) that continuously
poll (attempt to access) the CD-ROM drive. If these applications
remain open after the CD-ROM drive has been removed from the
notebook, system performance slows down. If you then close all
applications (such as the Compaq Sound System) that attempt to
access the CD-ROM drive, system performance returns to normal.
