That means flashing the bios and make it a newer model than it is ? I did that with an early intel mac mini some years ago so that i could put in more memory, also i changed the CPU from a single core 1.8Ghz to a core 2 duo 2.16Ghz.. wow what a difference it made..
No.

That means using things like LeopardAssist, or using a different Mac to install Leopard (one that is officially supported) on to the HD.

BIOS is an Intel PC thing. While a PowerPC Mac is a PC, it is not an Intel Mac.
 
I went to lowendmac.com but i cant really se an obvious link for downloading this browser.. it seem like i have tweak it and do things to get it to work ? i am not in to hacking at all so i need something that is just plug and play...

No, an Open Firmware command is issued that will make the computer report it has an 867MHz or higher processor inside, which will allow the Leopard installer to boot. Once the operating system is installed and the Mac reboots, that command is no longer in use as it was stored in volatile memory, but Leopard itself does not check for the MHz count. Only the installer disc does, although there are ways to modify the disc to disable the MHz check. But the OF command is easier. LeopardAssist issues the command for you.

You should be able to drop in a 7455 dual 1Ghz CPU daughter card with L3 cache into your 2002QS if you are so inclined - Plug n play. The Dual CPU does take a specific heat sink however. I upgraded my single 733Mhz 2001QS to a dual 1Ghz which took it from a fun hobby file server box to a completely usable daily driver. It is by far, my favorite PPC mac I have + it runs OS9. If you're willing to hunt & take your time, you can certainly find some deals on parts to max performance.

Leopard runs great with a DP, max ram and CI supported video card and IMO will improve its usability thus your experience simply through the amount of still-supported or mostly current software for it. Anyhow, have fun with your quicksilver :)
 

Like someone said earlier... my G4 800Mhz will be slower with Leopard installed ? I can see now that there is not very much apps available and working for this old 10.4.11.. so maybe a upgrade will 11.5 will make it more usable ?

Leopard is very slow if you have stock GPU in Quicksilver, you need some graphic card with Core Image. Also it is good to have at least 1 GB RAM. You can also make dual boot with Mac OS 9. For OS 9 are lots of great games and productivity software

I have a ATI Radeon 7500 with 32Mb RAM... it has a fan on the heatsink as well, none of my other Power Mac´s have that... even this will be to slow for Leopard ?

Like I said, all depends on what you want to do.
Technically Leopard will be slower but you might not even notice - Leopard has lots of visual features to wow you with, these are normally handled by the graphics card, however your machine's graphics card is not advanced enough to cope, so those features are passed off to the CPU - hence the preformance hit.
You can turn all those extra features off (advised) and carry on regardless.

There's no way around it - you are using a 15 year old machine, if you want to be online and do modern stuff, there will be work involved.

Yeah i got that, i started to use mac back in 2006 so i have never really used those G4´s on a daily basis, i think Snow Leopard is what was installed on my very first iMac 24" core2duo that i bought in 2006 for music production. I would maybe say that a 867Mhz CPU is maybe even to weak for Leopard to get it running smooth. Maybe i just gona go and put in another HDD and install Leopard and see how it runs.. if i dont like it.. well i´ll just swap back for the one that i allready have in there..

It probably would have been Tiger, seeing as Leopard wasn't released until 2007, and Snow Leopard wasn't released until 2009.

Well.. i am sorry.. what i meant was, i upgraded to Snow Leopard 2009 and i used what was installed when i bought the iMac from 2006 to 2009.

Slow.

How much slowness is too much? It depends on you. However, there is a certain amount of slowness that ALL of us who use these old Macs recognize as part of using them. You can either have a very fast Mac that is incapable of doing anything modern and thus looks pretty on your desk, but does not do much.

Or you can accept some slowness for a Mac of this era but still get work done. That is your choice, but one all of us using these Macs have accepted.

I ran Leopard on a PowerBook G4 400mhz with 1GB ram. It ran fine. We have a PowerMac G4 400mhz at work with less than 300mb of ram running Leopard. It's our print server so the MacPro can print to our Appletalk printers.

That G4 at one point had 1.75GB of ram and was doing production work from 2004 to 2013. Same thing I do on the MacPro. Ad design, page layout, legals, classifieds, scanning, word processing, email. It was a little slower than the G5 I used at the time, but it got the work done on time.

I hope you will act on your thought to try Leopard. There are people here who prefer Tiger and people here who prefer Leopard and people who have a criteria for what version of OS X gets installed on what model. Whatever type of preference or criteria you develop, do so because you've had your own personal experience with the OS in question. Some things may dissapoint you and some may surprise you but at least it will be your own assessment.
 
Slow.

Yeah you are right, i enjoy using those old mac´s for sure, i have several Power Mac G4´s, as for right now i am using my Quicksilver. Only thing that make me consider upgrading to Leopard is that it will open a door to alot more software that i can use.

I think i need a DVD burner that can burn on both sides to get the Leopard installed ? I dont think i have such thing at the moment, at least not a IDE one. Would be cool if i can just burn two DVD-R and use as installation disks, i saw that the Leopard file is over 6gb.. so thats alot.
 
This is how I install Leopard on my Mac:

- I split my HDD in two partitions (or I use 2 HDDs)
- I copy my Leopard copy .dmg file on it
- While running Tiger I open Disk Utility and restore the leopard dmg on the other partition (or the other HDD)

WOW.. that makes alot of sense.. i mean, it sounds like something i can do, i am going to put in another harddrive to test Leopard.. if i dont like it i just put back the tiger one. I am going to make 2 partitions and install tiger on it and try to do the same way you are doing it..

I was thinking.. how would that be possible ? in my case i can not just install Leopard because i have 800Mhz and it needs 867Mhz to install just like that.. otherwise i need that other application before i install Leopard.. is that possible with this method ?

That is how.

You're restoring a DMG of Leopard in Tiger, not installing Leopard. Once the DMG is restored, just boot.

Ohh yeah.. thats what i thought, well then its just to restore i guess, i have been thinking about overklocking this 800Mhz to 867Mhz... it seem simple and i cant imagen it would be any danger at all, its just 67Mhz more than it is now.. I guess a major overclocking is not a great idea due to overheating and such.. i think 800Mhz to 867Mhz would be just fine.
 
Well.. this is what i did, now i will not have any issues with installing Leopard.. its running nice and smooth.

Nice. How did you go about overclocking your QS?

This method?

http://power-mac-g4.com/g4quicksilverclockup.html

Since my DP1ghz is humming along, the above method is a weekend project waiting to happen with my single 733Mhz.

Yeah, pretty much but i did a different mod, i used a hole mounted resistor and soldered some tiny cables on to the PCB so that i can take the resistor out and go back to 800Mhz without taking out the CPU. In the past i have done similar things with dip switches and several resistors on some of my friends Power Mac´s so that its possible to choose what ever Mhz is wanted. We did not get the computer to start over 933Mhz though, i remember at 933Mhz it was getting very warm as well so i think with standard cooling 867Mhz is the best.
[doublepost=1492287794][/doublepost]Ohh.. this took me 35 minutes at the most..

Clean job - nice. Did you use an online resource or did you knock it out from memory?
 
It was getting more and more clear to me when i was thinking about this modell that this is what my friends used to have back in the days when i didnt know a **** about Mac OS, and i remember more and more when looking att the CPU, i had to check online where to put in the new resistor though, i could not remember that. Maybe i will put in some type of switch for the three stages that would possible be working for this model, 800Mhz, 867Mhz and 933Mhz, if this one will boot with 933Mhz i will have to get some more CPU cooling.

Right now with 867Mhz, its not getting even a tiny little bit warmer than with 800Mhz, so thats good.
