Sorry to follow-up my own post, but I think I've found my problem. \o/ After trying more approaches than I care to mention, I finally started pulling out memory DIMMs and the problem disappeared. With some trial and error, I traced the problem to, oddly, my two *newest* DIMMs--two 128 MB FPM 4K refresh DIMMs that I purchased from Other World Computing-- see this link: <http://eshop.macsales.com/Catalog_Item.cfm?ID=2420&Item=OWC5MD128MB> Note: these DIMMs work *fine* with a slower G3 ZIF processor; they only appear to cause a problem in conjunction with my 500 MHz G3 ZIF. I ran memory tests (TechTool and ramometer) on these DIMMs with both the old and new processor, but they didn't find any problems. Whatever's causing the problem may only be happening at startup/restart. Anyway, I'm now running swimmingly at 500 MHz (cache at 250 MHz) with just my "old" DIMMs. The now system restarts like before. My TCP/IP preferences aren't disappearing. Solid. :) The other 7300 user(s) (or anyone else for that matter) experiencing any problems with restarts after upgrading to a faster processor might want to try pulling out some DIMMs, especially any newer DIMMs similar or identical to those mentioned above. -Jeff [EMAIL PROTECTED] -- "Remember that if the women don't find you handsome, they should at least find you handy." -Red Green in _The_Red_Green_Show_ -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
