Hey..... Just ran across this the other day..... Tried to convert a 6500 (using dual Sup2-MSFC2-PFC2) from Hybrid OS to the newest version 12.1(8)E of the Supervisor (Native) IOS.... the image is larger than 16MB. Imagine my frustration as over and over I attempted to copy via TFTP and it would get 95% or so finished then throw up a read error and quit. I tried multiple TFTP servers, then realized what I bonehead I'd been when I was looking at the IOS download page and it's got a warning about files over 16MB with TFTP. Upon investigation, Cisco has a page that talks about the 16MB limit in all IOS TFTP facilites as well as most *nix TFTP server softwares. Strangely enough, tho, it doesn't mention the CatOS (which appears to have that same limitation like the IOS). They have a "fix" for the IOS "bug", but not the CatOS, so I was kinda stuck. I tried to setup an RCP server on a Solaris box to copy the file but ran into authentication issues that were not normal, and the only other option Cisco mentions is using FTP, which isn't available from the CatOS (Hybrid) (couldn't use the IOS on the MSFC to FTP the image because it needed to be in bootflash on the Sup and MSFC only saw it's own bootflash). Anyhoo.... the answer was to get the next oldest version of the Native IOS 12.1(5)C, which is under 16MB, perform the conversion to Native IOS, then at that point, use the FTP functions in the Native IOS to download and upgrade to the newest version IOS..... Geez.... Another problem I happened into was that we only had 16MB bootflash on MSFC (bootflash:) and 16MB PCMCIA (slot0:) memory, so running 12.1(5)C in sup-bootflash: took up almost 16MB and to download the newest IOS I had to wipe 12.1(5)C from sup-bootflash, then download the newest one (because they both wouldn't fit in 32MB sup-bootflash).... scary, but it worked! Just kinda FYI...... Mike W.
