        README.TXT (This file) Added for uploading to PC OHIO as further 
                               explanation on the installation of the drivers.

These files are updated files for use with VL bus IDE hard disk controllers
based on the Promise PDC 20230C OEM chipset controllers (I have a generic
VL Bus controller with I/O sold as VLIDE which is based on the PDC 20230C
and UMC chips) or the Promise DC 2300 controller.

These updated drivers allow use of these controllers with motherboard bios,
or bios extensions (such as the AMISIDK 8 bit add-in card) that provide LBA 
(Logical Block Addressing) to provide support for large enhanced drives 
(Such as my Western Digital AC2700 730 meg drive).

The VLIDE.386 Windows driver is a replacement for the standard Windows
WDCTRL driver and supports enhanced drives with LBA in Windows 3.1 and WFW 3.11
and supports 32 Bit Disk Access and 32 Bit File Access.

Install the dos driver with a line in the CONFIG.SYS file:
        device=c:\vlide\vlide.sys     assuming the driver is in a subdir
                                      C:\vlide

Install the Windows driver as follows:
        Copy the VLIDE.386 file to C:\WINDOWS\SYSTEM directory
        Edit the Windows SYSTEM.INI file in the C:\WINDOWS directory
        carefully using a text editor such as DOS EDIT or Windows Notepad.
        Find the lines in the section:
        
        [386Enh]
        device=*int13
        device=*wdctrl

        remark out the line for the default WDCTRL driver by adding a
        semicolon in front of the line
        ;device=*wdctrl

        Add a line for the Promise Technologies driver VLIDE.386
        [386Enh]
        device=*int13
        ;device=*wdctrl
        device=c:\windows\system\vlide.386

        Save the file and restart windows

Although these updated drivers will not make these controllers into 
Enhanced Mode 3 PIO controllers, they do extend the use of DC 2300 and
PDC 20230C hardware.

Promise Technology does make a new Enhanced Controller, EIDE DC 2300 PLUS,
for VL bus systems that will provide hardware Mode 3 PIO support for enhanced
IDE drives.
