i just got my first mac working. its a B&W G3 running 350MHz on a rev 1 board currently running os 8.6 (trying to track down osx). i had a 450MHz cpu lying around in a non working rev 2 board. i dropped the 450 into my B&W and now the chime is gone. also the system info still shows that its running at 350. whats going on? i've taken the 450 out and put the old 350 back in, but all chimes are still gone. is there any way to get them back and get the 450 working all the way? i've heard something about pressing a button near the battery. should i do this? if so when? before booting? after? w/ or w/o the system plugged in? hold it a sec or just press and let go? i've been building PCs for a while but this is my first mac. i have no idea what i'm looking at in there. thanks in advance for any help.



ps. sorry if this has been answered before, but my search came up w/ nothing.

    The chime can disappear simply by shutting down the computer while it is muted. I would test for that first. As for the processor speed, I think that is configured by jumpers and is based in proportion to the motherboard speed. I don't know the settings you want, but it is not that much of a boost IMHO.

    thanks for the mute info. i thought about that right after writing the post and it seems that is the case. as for the cpu speed, it is over a 25% increase which is significant IMHO.

    I am sure that http://www.xlr8yourmac.com has info on the jumper settings that you need.



    Moving to Genius Bar.

    In OS 9 that CPU speed would make a noticeable improvement, but in OSX, it doesn't much. OS X has a knack of adapting to your computer by turning off bells and whistles. My 400Mhz laptop is surprisingly similar to my Dual G5 in terms of response (5400PRM drive limitations not included) and other OS X related things. (When it comes to brute-force processing there is a obvious performance gap) I don't think your 25% would allow OS X to enable any other features that 350Mhz can't handle.



    I just think it is more trouble than it is worth, but then tinkering in a computer is sometimes fun. 8)

    Thanks, Ebby. More good info. i had hoped to see a difference in OSX, but the fact that your 400 (a g3 i assume?) responds as well as the G5 is very impressive. I still plan on using the 450 since the hole reason that i bought this old G3 was the learning experience before i drop the money on a dual G4 or maybe a mini. (i'm a broke college student, it makes me happy to pretend that the G5s just dont exist.) I've pretty much got the whole PC thing down now i'm tryin to master the hardware and software of a mac. i've got a way to go.

    now to see how much help that link offers...

    Well, the link worked, and so did my 450. while i was in there i decided to toss in some spare parts. heres my old and new specs...

    Look for Disk Setup on the CD or Utilities folder. Kinda the same thing as Disk Utility in OS X.



    Glad to see it all works.
