Great. I've tested APEX 1.5.8 on my 128MiB slug. The default startup will scan for up to 256MiB of RAM (the maximum that the IXP42x can address). I recall that there was a thread of discussion about automatically upgrading APEX when a new package is installed. Was this resolved? In order for me to install a new APEX, I had to take the /boot/apex.flash image, byte swap it, and then put the sercomm header on it. I can also put a copy of apex with all of those steps already taken into /boot so that it is really easy to upgrade (or downgrade for that matter). Generally, I'm not in favor of redundancy of this sort. There should be a simple tool for handling this, but I haven't seen one. I suppose the alternative would be for me to write a small tool that is capable of installing APEX into flash. It would be easy to look for an existing version in the target partition and then do the swaps and headerization. Now that I write this, I think I'll do this in any case. If it's usefull, then so be it. Cheers. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
