Technical Frequently Asked Questions ================================================================================ Subject: T.1 What is the latest official ROM release(s)? -------------------------------------------------------------------------------- 1.04 For Elite 2864 model 1.09 For Elite 2864I model 6.15 For U-1496 modems with 1-Mbit EPROMs 5.05c For really old non-U-1496plus models with 1-Mbit and 512-Kbit EPROMs 6.23 For U-1496P (portable) model The ROM release previous to the 6.15 was version 6.14. The latest quick reference card and the release notes for the latest ROMs can be obtained via anonymous FTP from the Taiwan or USA FTP sites. When a new official ROM revision is released, it is available for *ALL* ZyXEL modems. Thus when the 6.14 ROMs were released for the U-1494E modems, it was also available for the E+/B/B+/S/S+ modems (and other ZyXEL models). Beta ROMs have been known to ship in modems supplied by ZyXEL USA, so you may have a newer version than those listed here. User Contributions:Section Contents
