setup. Please consult your computer manual on how to change this setting
since it may be named differently according to the respective BIOS. In
most of the cases, you can find it under the name USB Legacy Support or
USB Keyboard Support (often under Integrated Peripherals or Advanced
Options).
NOTE: In some of the cases, problems with the PS/2 keyboard and/or
mouse occurred with an activated emulation for PS/2 devices. If you do not
use any USB input de-vices, please switch off the PS/2 emulation in the
BIOS setup.
General problems
Slowed down system
If you think the speed of the total system or the copying speed – also with
IDE and SCSI devices – is too slow, a USB controller can be the cause,
even if it is not used.
Read, write and verification errors
If EZ Gig reports errors, these are usually defective areas on the

noticeable by a very high number of displayed errors. First of all, try
to fix the problem via the help instructions for the respective hardware
types (IDE, SCSI, USB) because the causes are usually found there. If
the problems cannot be fixed this way either, deactivate step by step the
following options, at best in the indicated order:

Read cache and write cache
FastCopy

SharedMemory
If the problem does not occur any more after having deactivated a certain
option, the previously deactivated options can be reactivated as a test.
