Troubleshooting
Notes:
Windows versions 4.00.950 and 4.00.950A will not exibit this problem. These versions do not have
an IRQ steering tab or the option to enable Windows to steer IRQs. IRQ steering is done by the BIOS.
Windows versions 4.00.950B and 4.00.950C will exibit this problem only if the option to enable IRQ
Steering is enabled. Windows, by default, does not have this option enabled.
(Refer to Article number Q182604 in the Microsoft knowledgebase for a complete description of PCI
bus IRQ steering.)
Installer can not find the first file during Lexicon Studio installation
At the start of the installation process, after Windows has identified the new hardware, it searches for
the drivers. In some cases Windows will not search the correct drive, and you must manually specify
the path to the A:\ drive (if installing with floppies) or the D:\ drive if installing from CD-ROM by clicking
the Browse button. Once you have done this, click Finish. All of the drivers will be copied from the
proper drive.
Studio sharing an IRQ with 'IRQ Holder for PCI Steering' in Device Manager
This is normal. An IRQ Holder for PCI Steering may be displayed when you view the System Devices
branch of Device Manager. An IRQ Holder for PCI Steering indicates that an IRQ has been
programmed to PCI mode and is unavailable for ISA devices, even if no PCI devices are currently
using the IRQ.
Various problems if you have incorrectly updated your Lexicon Studio software
The following problems may appear if you incorrectly update Lexicon Studio drivers:
1. Clicking on the Launch Lexpanel icon in the System Tray causes the following message "Could
not bring up Control panel" (with OK button)
2. No driver file appear in the Lxstudio Folder
Reason:
Update Driver was performed incorreclty. Selecting NO, for 'Do you want windows to search for a new
driver?' causes the Device Driver Wizard to use the old .inf file from the previous version installed.
