CD Rom Basic RE-INSTALLATION information: 1.) Make sure that there is a C:\SCSI subdirectory on the bootup hard drive. There should be at least these files in that directory: NECCDR.SYS MSCDEX.EXE SCSITEST.EXE ------------------------------------------------------------------------ If you don't have these files you should get the latest version of the drivers from our BBS at 1-508-635-6328 (1200/2400/9600, 8,n,1).

First run SCSITEST which will test the hardware installation and integrity. Run the TEST HARDWARE selection. It should follow through several menus and alert you to any potential problems. 3.) Next make sure that the following statements are the first and second lines in your CONFIG.SYS file in the root directory on your hard drive. DEVICE=C:\SCSI\NECCDR.SYS /D:NECCD LASTDRIVE=Z 4.) Finally for standard setup be sure that the following statement is the first line in your AUTOEXEC.BAT file in the root directory on your hard drive. C:\SCSI\MSCDEX /D:NECCD /l:l Your CD-ROM drive will now be setup as drive L. If everything is setup correctly this should rectify any problems. ------------------------------------------------------------------------- ERROR MESSAGES ------------------- If you encounter a CDR 101 error this is a designation that there is a timing problem. 1.) Verify that the cable is secure at the PC and at the CD-Reader. 2.) If you have the termination block in the back of the CDR77 or CDR72, remove it. 3.) If you do not have the termination block in the back of the CDR77 or CDR72, put it in. 4.) Try placing the card in another bus slot in the PC. 5.) If the machine is running in a TURBO mode, try a slower clock speed. 6.) Make sure the CD-Rom is in right-side-up. 7.) Make sure the dip switch settings on the SCSI card are in the correct position. If you encounter a CDR 103 - Disk not High Sierra or ISO 9660 format error, this is a designation that something in the system is overwriting the memory map of the SCSI card. The card should come with all dip switches in the down position. Refer to page 13 in the SCSI installation manual for card memory map settings or see above switch settings. Check to see that no other card in the system is using the memory map area that is set aside for the SCSI card. (Page 13) Check VGA cards. Most will grab other areas of memory that they shouldn't. If the VGA card is the culprit, try placing it in an 8 bit slot. Check memory maps of memory boards. Make sure that memory managers (usually implemented in the CONFIG.SYS statement) have the memory area excluded that the SCSI card is using. Check with the computer manufacturer about how to disable video, disk, bios, and system caching. All these features need to memory addressed.
