The WRT54GL has a 4MB Intel Flash chip which is able to store CFE, NVRAM settings, an operating system (like OpenWRT or LinkSys' operating system (or even XINU), and optionally a file system. Currently the bleeding edge version of XINU in the flashmem branch has a working Flash driver, though it is not the one on this page and will be replaced with the driver described in this document. GL-series routers have 2 erase-block regions (8-8KB and 63-64KB).

Flash memory remains minimally tested on the WRT54G. XINU reports that the G-series has 2MB of Flash memory, separated into 4 regioins of varying erase-block sizes (1-16KB, 2-8KB, 1-32KB, and 31-64KB).
