Installing a Flash-ROM Upgrade With ftp
You can upgrade the firmware on the 1765 LAN card by
installing a flash-ROM upgrade. Unlike other read-only
memory, flash-ROM is rewritable. This section describes
how to prepare for and install a flash-ROM upgrade
using ftp.
Preparing to Install
Before you install a flash-ROM upgrade, you need the
following
• You need a copy of ftp, the file transfer protocol
software. Ftp is included with Windows for
Workgroups, Windows 95, and Windows NT.
• You need to know the LAN card’s IP addr ess, which
is printed on the configuration page. See “Print a
Configuration Page” on page2-13.
• You can not install a flash-ROM upgrade across
LocalTalk. Remove any LocalTalk connections
before performing a flash-ROM upgrade.
WARNING! During the flash-ROM upgrade LAN
card settings restore to factory default values. Any
changes you have made will be lost. Use NEC 1765
software to reconfigure the Silentwriter. Be sure to print a
configuration page before installing the flash-ROM
upgrade so you will know what values have been
changed. To upgrade without restoring parameters to
factory defaults, use FWTOOL to perform firmware
upgrades. See “Installing a Flash-ROM Upgrade With
FWTOOL” on page B-5.
