At this point, the device driver and utility software should be copied to the
hard drive. On the test unit, the QDRIVE.SYS driver was copied to the C:\SYS
subdirectory, and the QDRVLTR.EXE, QDRVCHK.COM and HXBIOS.COM
utilities were copied to C:\DOS. the CONFIG.SYS file was then edited to add
the following line:
DEVICE = C:\SYS\QDRIVE.SYS
This device driver acts as an extension of the drive handling capabilities of
MS- DOS, allowing the DrivePort to be recognized on boot-up. On the test
system, logical drives C, D, and E were already assigned to the internal hard
drives, so QDRIVE.SYS assigned logical drive F to the DrivePort. If the system
is booted without a hard drive cartridge mounted in the base unit, there will be
a pause while the device driver retries the DrivePort. It will then proceed with
the boot process without installing the device driver or assigning a logical
drive.
NOTE: Installing or removing a hard drive cartridge while the system is
powered on may result in severe damage to the drive, the DrivePort, or the
computer. Always turn the computer off before installing or removing the hard
drive cartridge.
QDRVCHK.COM provides technical statistics on the mounted DrivePort, similar
to the DOS CHKDSK command. HXBIOS.COM can be executed if the system
was booted with no hard drive cartridge installed and QDRVCHK needs to be
run. QDRVLTR.EXE will provide the DrivePort’s logical drive assignment.
The hard drive cartridge must be initialized on the LT-286e or LT-386SX.
The low - level format and partitioning cannot be done via the DrivePort. Also,
the DOS - level format must be performed for the first time on the laptop - it
may then be formatted while installed in the DrivePort.
In testing, the DrivePort performed as if an additional conventional hard disk
drive had been installed. File and directory copies, application program
execution and BACKUP/RESTORE functions were tested with no problems.
