                 Bravo MS Problem Reading Files from CD-ROM


PROBLEM

When executing a file from CD-ROM, the system may lock-up in DOS or cause 
General Protection Fault errors in Windows.


CAUSE

When using one or two hard disks on the primary IDE controller, and a CD-ROM 
on the secondary IDE controller, the second IDE controller "First Hard Disk" 
may be incorrectly set as "NONE" in system BIOS.


SOLUTION

When the CD-ROM is connected to the secondary IDE controller, the "First 
Hard Disk Type" must be set to "AUTO" in the SETUP Menu due to system 
BIOS design.
