4. DOS ASPI DRIVERS & UTILITIES
Note:
With the More Than 2 Drives Support option enabled in the PCU, you will be able
to install up to eight drives without installing device drivers. Of course, your DOS
version must be 5.0 or higher.
LOCK/UNLOCK functions are crucial for data integrity of removable devices and need to be
supported by drivers. To prevent the data from being destroyed by improper operation of
your devices, it is recommended to use the DOS 4.x or higher SHARE utility for automatic
LOCK/UNLOCK support. This can be done by adding SHARE.EXE to your
AUTOEXEC.BAT file. After loading share.exe, the system will LOCK your media when
opening a file and UNLOCK it when closing the file. This means that removable media can
be ejected and changed at any time as long as no file is opened. This change is transparent to
the user, and DOS logical drive information will be updated automatically every time the
cartridge is changed.

Disk Partition Utility
TFDISK.EXE is a disk-partitioning program for modifying or creating partition tables under
DOS. Valid DOS partitions can be created by DOS FDISK only for drives controlled by
BIOS INT 13H. Drives controlled by TRMDISK.SYS must use TFDISK.EXE. After you
partition a disk device with TFDISK you must also run the DOS FORMAT command on the
device before you can use it. To run this program, you have to install the ASPI drivers first,
then add a line after ASPI driver, i.e., add two lines to the CONFIG.SYS file:
DEVICE=C:\ASPI\ASPI.SYS
DEVICE=C:\ASPI\TRMDISK.SYS
To partition a disk, simply type TFDISK.EXE at the DOS prompt (NOT the MS-DOS
Prompt under Windows). Two translation methods are available, depending on the disk
space: <1GB or >1GB.
• <1GB Translation
Method:
Heads = 64
Sectors = 32
Cylinders= XXX - Depends on drive’s capacity.
• >1GB Translation
Method:
Two methods available:
•
Using default disk parameters:
This method reads and uses the parameters from the master boot
record of drives used previously with other adapters. If no
previous settings are available, the 64Head/32 Sector parameter
scheme is used.
Heads = 64
Sectors = 32
