The DPT driver for SmartCache Plus adapters ships with Windows 95.

Prior to installing Windows 95, it is recommended you set your CONFIG.SYS
FILES equal to 40 and the BUFFERS equal to 40.

After Windows 95 is installed and booting from your hard drive, edit your
CONFIG.SYS file and remove any lines that load the DPT 16-bit ASPI and/or
