                      PCMCIA CDROM driver installation
                           for Windows NT Ver 4.0

Windows NT Ver 4.0 does not recognize PLUG & PLAY hardware adapters and
does not allow hot insertion or removal of PCCards (PCMCIA cards). 
You MUST therefore insert the CDROM PCCard before booting up under 
Windows NT. 

PCMCIA CDROM Driver Installation under Windows NT 4.0 :

   1.  Click Start, point to Settings, then click Control Panel.

   2.  Double click "SCSI Adapters."

   3.  Select the "Drivers" tab and click the "Add" button.

   4.  Click "Have Disk" and insert the CDROM Install diskette 
into the computer's floppy drive.

   5.  Click "Browse" and select the drive letter for the floppy drive.

   6.  Double Click on the icon of the folder WinNT, Click Open and 
Select OK. The path to the CDROM NT drivers should be 'A:\WinNT' or

   7.  When the list of adapters appears, highlight the adapter 
MINICD and click "Next" to continue.

   8.  Click "OK" for Windows NT to install the necessary adapter 
driver on your system.

   9.  Click "OK" to exit.  Note that you need to reboot your system for 
the new drivers to take effect.


On a number of notebooks (Toshiba's Tecra, Sony's Vaio, Fujitsu's Biblio...), 
Windows NT 4.0 fails to assign correct IRQ's to PC Card devices. 
For instance, it often happens that IRQ 7 or 9 are affected to a PC Card
peripheral whereas it has already been assigned to some internal peripheral.

If after having installed the CDROM driver as explained above, no drive 
icon is displayed for the CDROM drive and the driver is shown to be installed 
and running in, 'Control Panel -> PC Card -> ARC ATAPI -> Properties', then it 
is likely that some IRQ conflict has occurred preventing the drive from 
functioning properly.

Use the ARC_IRQ installer utility to remedy this problem.  If the problem persists, please contact your vendor.
