Modem Upgrade
This chapter describes how to upgrade flash electrically erasable programmable read-only memory
(EEPROM) firmware on your Model XM128 ISDN Digital Modem.
Upgrading with Flash EPROM
Your Model XM128 modem employs a flash EEPROM that lets you conveniently download
updated firmware and program the modem with new features and enhanced functions. If you are
using Windows 95 or Windows NT, use the NETGEAR Internet Configuration Manager to
upgrade the firmware. For other operating systems, use a terminal program that supports the
X-modem Protocol.
Obtain the new firmware from the NETGEAR bulletin board system (BBS), WWW, or FTP site.
Refer to Customer Support on page -iii. The firmware is distributed in the ONETd.vvv file, where
the extension vvv denotes the version of this firmware.
Table 9-1 lists the definitions for the d
modifier in the file name.
