Model: DS-XG PCI or WDM
Operating System: Windows 95 & Windows 98 (Note: might work with other versions of this os.)
These are the drivers that should fix the PCI parity error 0100h problem.
You need to run setup.exe instead of updating the driver from the control panel.
Make sure that you have the old driver disks as well as it asks for a file* that isn't included in these new files.
*Not every Sony laptop will require the file, but do search on your Windows98 CD, your CAB files as well as your driver disks.
