Just in case it matters, here's half of the article at: http://www.lowendmac.com/musings/foot.html Firmware Upgrade Disables RAM by Dan Knight 2001.03.25 Before I even knew there was a firmware update for my PowerBook G4, the Mac Web let me know that a lot of users were having problems with it. These updates were posted late Friday, March 23. By Saturday morning, sites like Accelerate Your Mac, Mac Observer, MacCentral, and MacFixIt were reporting big trouble for some users. Big trouble. Some third-party RAM modules were no longer recognized after the firmware update -- but some non-Apple memory worked just fine. Apple branded memory (at about 4x the price) appears to be unaffected by this problem. The updates (v4.1.8 for Power Mac G4s, v4.1.8 for Cubes, v4.1.8 for PowerBooks with FireWire, v4.1.7 for slot-loading iMacs, and v4.1.7 for iBooks) are supposed to improve FireWire target disk mode, network booting, gigabyte ethernet (on models so equipped), and system stability. Note that this is not a required update. In reading the TIL articles about these upgrades, there is no warning that they may disable memory that has been working flawlessly in your computer until now. If the price of increased system stability and improved FireWire target disk mode is the possible loss of some or all third-party memory in your computer, it's a price not worth paying. In my case, all my RAM is third-party, so I could end up with a completely nonfunctional computer. I am not trying the update. As MacFixIt notes, there appears to be no way to test memory in advance, no way to know whether you'll get burned by this update or not. That's a risk no Mac owner should have to take. -- The iMac List is sponsored by <http://lowendmac.com/> and...
