1) Go to Start -> Settings -> Control Panel -> System -> Device Manager
   -> SCSI Controllers. 

2) Remove the 'AdvanSys ISA PnP SCSI host adapter' driver.

3) Turn off the computer and move DIP switch 3 on the back of the SCSI card 
   to the 'off' position.  All 4 switches should now be in the 'off' position.

4) Turn the computer back on and double-click on the 'Add New Hardware' icon 
   in the Control Panel. 

5) Select 'No' so Windows doesn't search for the hardware.  Click [Next], 
   and choose 'SCSI Controllers' from the device type listing. 

6) Click on [Have Disk], and put the CD Master floppy disk into the drive. 
   
7) Choose the 'AdvanSys ISA SCSI host adapter' (not the EISA, which is first 
   in the list alphabetically) and continue through the rest of the dialogs. 
   Do not restart the computer when prompted after the installation is 
   finished.

8) Go to Device Manager -> SCSI Controllers and write down the settings 
   (I/O, IRQ, DMA) that were assigned to the Advansys ISA SCSI host adapter.

9) Restart the computer in MS-DOS mode and run the "cfg5140.exe" from the 
   CD Master floppy disk. 

10) Under 'Adapter Configuration', match the Device Manager SCSI settings
    that you wrote down in step 8.

11) Save these settings by selecting 'Write settings and exit'. 

12) Remove the floppy from the drive, and reboot the computer back into 
    Windows. 

13) Go to the Device Manager.  Under SCSI devices there should no longer be
    a '!' mark next to the ISA SCSI host adapter, and under CD-ROMs, there 
    should now be an entry for the Ricoh RO-1420c.
