Version:      1.1f2
Released:     September 17, 1997
Requires:
PowerBook 3400 with Internal Modem/Ethernet 33.6 card
Description:
Contains "PowerBook 3400 Ethernet" version 1.1f2 and
"PowerBook 3400 Modem" version 1.1f2. Resolves issues with
the PowerBook Internal Modem/Ethernet 33.6 card not
resetting properly and intermittent Zmodem protocol
transfers. This software is provided "as is" and is not
supported by Apple technical support. A future System Update
is expected to include the final versions of these drivers.

This software consists of a Disk Copy NDIF (New Disk Image
Format) compressed image, which requires Disk Copy 6.1 or
later to use. Download this software to your hard drive and
then double-click it to use it. Disk Copy is available in
the Utilities folder.

Disk Copy 6.1 (or later) or Disk Image Mounter 2.1 (or
later) from Apple are the recommended applications to access
all disk images released by Apple and are the only supported
applications to access NDIF disk images.
