3Com 3C509B ODI Driver Fails to Load in Windows 95 (132287)

This article was previously published under Q132287 SYMPTOMS
When you attempt to load the ODI driver for the 3Com Etherlink III 3C509B
Plug and Play network adapter, the driver fails to load or is unable to
find the adapter at the specified I/O address. However, if you restart
Windows 95 and choose "Safe mode command prompt only" from the Startup
menu, you can load LSL and 3C5X9.COM without errors.
CAUSE
This problem can occur if Windows 95 sets the adapter to Plug and Play mode
before the 3C5X9.COM driver is loaded. Because the 3C509B adapter is a Plug
and Play adapter, Windows 95 attempts to enumerate the adapter along with
the other Plug and Play devices on the system during the boot process. The
enumeration process sets the adapter to Plug and Play mode, causing it to
no longer maintain its manually specified hardware settings. This causes
the driver to fail to locate the adapter.
RESOLUTION
To resolve this problem, use the 3C509B configuration utility to disable
support for Plug and Play when using an ODI driver.
NOTE: You can also disable Plug and Play for the 3C509B adapter by
obtaining the latest EtherDisk (version 4.2) for the Etherlink III and
running the PNPDSABL.BAT file located in the root directory of the disk.
