upgrading the ibook clamshell's L2 cache to 1MB

[alectrona6400]

welp, got the new chips in and well... it still isn't passing the mac os 9 built in memory test for cache. starting to think its either address lines or firmware related. dunno if the firmware on here has ever been updated, as a matter of fact. i know for certain these chips are good.

well, tested the computer some more and it does work, but disables the L2 cache for whatever reason. maybe lack of address lines or something. gauge pro also doesn't properly see my bus overclock, and assumes the CPU is running at 266MHz with the 66MHz bus even though i had set the bus to run at 100MHz...

Totally not directly related, but BITD, about a year and a half after I got my DA/733/1M Superdrive model, I started getting the same error you're seeing completely out of the blue in os9, but not in osx... I ASSUME there's some kind of integrity check but i doubt there's any diagnostics for this.

Definitely interested if you can pull this off tough!

OS X definitely does the checks, and you can check in system profiler if something is amiss or has failed.

Oh definitely- I just meant that on that specific machine, i didn't even know it'd failed because OSX doesnt do the popup, and classic wasnt notifying. Anyhow.. definitely gonna be following your attempts if you plan to keep trying!
