Problems Running CD-ROM Software
Drive Letter Mapping If you have inserted a CD-ROM successfully, but the software on it refuses to
run or produces error messages, the software may expect the CD-ROM data to
be at root level. This is often the case with installation programs.
In the NetWare and Microsoft & IBM networking environments, you then
need to map that disc to a drive letter of its own. In NetWare, the Show All
Volumes parameter must be enabled.
MSCDEX Driver Some CD-ROMs, e.g. the single user version of “Computer Select”, requires the
MSCDEX (Microsoft CD-ROM Extension) driver. The volume is usually
released in a network version as well. Axis has developed two MSCDEX
emulation programs:
• AXCDEX for Windows 95
• AXISCDEX for Windows for Workgroups
The required software is available on the Axis Web Site at
http://www.axis.com/products/software. The MSCDEX emulation makes a
CD-ROM on the StorPoint CD look as if it was locally connected to the PC.
Single User Version If the CD-ROM is a single user version, refer to your software license for the
terms of use. You can restrict the number of simultaneous users to one by setting
the User Limit parameter. Refer to “General Disc Settings ” on page 34.
Default Names Some applications look for information on the CD-ROM using its default name
- if you have set a volume name it may not recognize the disc and fail to run.
Difficulties Locating the StorPoint CD in NetWare
There are basically two different frame types on Ethernet networks, Ethernet II
or IEEE 802.3. The IEEE 802.3 frame can be encapsulated in an IEEE 802.2
LLC frame or a SNAP frame. All four frame types are enabled by default with
the value
auto , which means that your StorPoint CD automatically adapts to
the frame type used on the network. This will meet most requirements. Frame
types that are not in use in your network will not be used by the StorPoint CD.
However, depending on your network, you may want the StorPoint CD not to
operate on some frame types. If your network has multiple sections with
different frame types on some of the sections, then the StorPoint CD might log
on to the wrong network section and adapt to a frame type incompatible with
the intended network section. For this reason, you have the option to disable
those frame types by changing the parameter from
auto to off .
Alternatively, it is possible to use the eight digit network number appropriate to
your segment of the network, in the form xx-xx-xx-xx (e.g. 00-3F-B5-01). In all
normal cases this will not be necessary since autodetection will handle most
cases. However, this must be done by directly editing the
config.ini
file
located in the System/ServerProperties folder using a text editor. Although
you cannot enter the network number from a Web browser, you can display the
frame type and change the value to
auto or off , if required.
