AXIS StorPoint CD Token Ring - User’s Manual 105
Problems Running CD/DVD Applications
Drive Letter Mapping If you have inserted a disc successfully, but the software on it refuses to run or
produces error messages, the software may expect the CD/DVD 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/DVDs, 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/DVD on StorPoint CD look as if it was locally connected to the PC.
Single User Version If the CD/DVD 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 32.
Default Names Some applications look for information on the disc using its default name - if
you have set a volume name it may not recognize the disc and fail to run.
Difficulties Locating StorPoint CD in NetWare
There are two different frame types on Token Ring networks, IEEE 802.2 or
SNAP. Both 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. If a frame type is not used in
your network, it will not be used by StorPoint CD.
However, depending on your network, you may want your StorPoint CD not to
operate on both frame types. If your network has multiple sections with different
frame types on some of the sections, then 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 a
frame type 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.
