Bad Photo CD Disc

If you can see a list of files from your Photo CD (after issuing a DIR command), but
cannot read them, or experience errors while reading them, you may have a bad Photo
CD disc. Try another Photo CD disc. If it works, you should have the defective disc
replaced.

Possible Causes and Solutions

Improper SCSI Device Driver Installation

Your computer needs a SCSI software device driver to link the SCSI interface board
to the CD-ROM drive. If this driver cannot be loaded properly, an error message will
normally be displayed on the screen.

Try rebooting the computer. Watch as the CONFIG.SYS file executes and look for an
error message to appear. You can press the Control and S keys simultaneously to
freeze the display in order to read the error message (use the Control and S
combination again to continue).

If the SCSI device driver cannot be loaded properly, either a software or hardware
conflict exists. Software conflicts are generally caused by memory managers; hard-
ware conflicts by two peripherals vying for the same DOS address space. Please read
the next two paragraphs on software and hardware conflicts.

Software Conflict with Other Device Drivers

The SCSI interface board normally designates the CD-ROM driver as the first device
driver loaded by the computer. When the computer has a memory manager (e.g.,
HIMEM.SYS, 386MAX.SYS or QEMM.SYS), in most cases the memory manager is
loaded first and the CD-ROM driver loaded directly thereafter.
