Windows 3.1 and Hardcard Plus 80 II

When you run Windows 3.1 on a computer with a Hardcard Plus 80 II, youmust have version 1.4 or later of the Hardcard driver to run MS-DOS-basedapplications in 386 enhanced mode. Earlier driver versions cause thefollowing error message:
Serious Disk Error:

A serious disk error has occurred while writing to drive C Continue will retry to the operation.

Press any key to continue
Use ATDOSHC2.SYS version 1.4 or later in your CONFIG.SYS file, and makesure VIRTUALHDIRQ=OFF is in the [386Enh] section of SYSTEM.INI file.

Windows 3.0 and Hardcard 40/80 II

ATDOSHC2.SYS version 1.3 has been known to cause erratic disk reads underWindows 3.0. According to Plus Development, this problem has been correctedin version 1.31 for the Hardcard II 40 and 80 cards.

The new driver has the following file date and size:
   ATDOSHC2.SYS     22310 05-17-90				
(According to Plus Development, the 1.31 drivers' disks have "Revision C"printed on the label.)

There are currently no Windows 3.0 drivers available for the Hardcard20 or 40.

General Information on Hardcard Plus

There are three separate types of Hardcard Plus cards and they fall intothe following categories.
Card & Size     Model       Driver          Version      VIRTUALHDIRQ=----------------------------------------------------------------------20 MB           8-bit       ATDOSHC2.SYS    1.31         yes40 MB           8-bit       ATDOSHC2.SYS    1.31         yes40 MB           Standard    ATDOSHC2.SYS    1.4          yes80 MB           Standard    ATDOSHC2.SYS    1.4          yes50 MB           XL          ATDOSXL.SYS     1.5 or 1.7   no105 MB          XL          ATDOSXL.SYS     1.5 or 1.7   no				
ATDOSXL.SYS version 1.5 requires a /W parameter. None of the XL modelsneed the Windows VIRTUALHDIRQ statement.The following table lists the address ranges that the specific HardcardPlus cards may use in the upper memory area (UMA). If there is a memoryconflict, try using an exclude statement on the EMM386.EXE line inCONFIG.SYS (X=A000-EFFF). If the exclude solves the problem, you can usethis table to further narrow down the exclude range.
