6.1 About Update via Internet
Question:
“Removable Disk” icon does not
appear in the catalogue of “My computer” after
the CF card reader/writer is connected to the
USB port of computer. Why?
Answer:
Possible cause:
there may not be driver for CF
card reader/writer in the computer. The default
driver is with the operating systems like
Windows Me/2000/XP, Mac OS 9.x/Mac OS X
and Linux 2.4.X. However, there is no such
default driver with Windows 98.
Solution:
Check if there is the driver for CF
card reader/writer in the computer. If the
computer uses Windows 98 operating system, it
is necessary to install the driver into computer
by using the CD-ROM provided with CF card
reader/writer.
When the CF card reader/writer driver is
installed successfully, a “Removable disk” icon
will appear in the catalogue of “My computer”.
Usually it is listed after original disk drive. For
example, if there were drives A, B, C and D
originally, the removable disk will be “E”. If there
were drives A, B, C, D and E originally, the
removable disk will be “F”. The rest may be
deduced by analogy.
