Sort of Off Topic... SeaMonkey on G4 Gigabit
This question is regarding a certain newsgroup, (I subscribe to Giganews), that I can no longer connect to. I know that the group is still alive as you can pick it up on google but that really sucks. I subscribe to twelve groups, (including this one), and have no problems with any of the others. BTW, Giganews tech support states that there is no problem on their end and I'm sure that they're right. Anyway, back in the old days when this happened, simply unsubscribing and resubscribing usually fixed the problem. But that was in the good old OS 9 days. Any suggestions?

Re: 64-bit question
-- Original message -- Subject: 64-bit question Date:Samstag 16 Oktober 2010N From:Arnel Tuazon a.tua...@gmail.com To: G-List g3-5-list@googlegroups.com I know my G5 is 64-bit (I have the late 2005 dual core PPC G5), but is Leopard (10.5.9) 64-bit? Yes and no. The kernel is 32-bit, but it can run 64-bit applications. Tiger could also run 64-bit applications, but not in the GUI i.e. Aqua → only console applications can be 64-bit under Tiger. Since Leopard also a GUI application (Carbon, Aqua) can be 64-bit. Keep in mind, that 64-bit is only useful for 4 GB of memory. You also have to distinguish between system memory and application memory. * A 32-bit application will always be limited to use as much as 4 GB of memory (physical or virtual). A 64-bit application can use all the memory you've got. * A 32-bit kernel can handle more than 4 GB of memory, so the kernel is not the real issue here. I've been looking on the net, but couldn't find a definitive answer. If you are really interested, read this article: http://arstechnica.com/apple/reviews/2007/10/mac-os-x-10-5.ars/6 Quote: “Apple has [with Leopard] gone 64-bit across the board, with two major exceptions. The first is the kernel itself, which remains 32-bit in order to maintain compatibility with existing drivers. …” Some more links: http://en.wikipedia.org/wiki/Mac_OS_X_Leopard http://www.appleinsider.com/articles/08/09/04/road_to_snow_leopard_twice_the_ram_half_the_price_64_bits.html I was told that only 10.6+ is 64-bit. True, when including the kernel. Snow Leopard can boot into a 64-bit kernel also on desktop computers and laptops, when you hold down the keys “6” and “4” but the default kernel is still 32-bit. This is due to compatibility to existing applications. Kernel extensions (.kext) will only work with the right kernel, so 32-bit extensions require a 32-bit kernel. A lot of desktop applications require specific kernel extensions in order to function. Snow Leopards defaults to the 64-bit kernel on servers, since extensions are not so importaint there, but memory is! If this is true is there an alternative OS that will run at 64-bit on the PPC G5? The only operating system I can come up with is Linux. There may be others though, like commercial Unices like AIX or so, but I'm not sure if they even run on a Power Mac. AmigaOS/MorphOS is also a PowerPC operating system, but I don't think it's 64-bit. Note that Linux has the same problem Mac OS X has when running a 64-bit kernel: extensions (Linux: kernel modules) will only run on the right kernel. For GUI applications 32-bit programs will require a 32-bit version library. So if your system is all 64-bit, you may not be able to run 32-bit programs at all. Of course, this is not so much of a real problem under Linux, since most applications are open source software anyway (and therefor 64-bit versions are possible with an estimated 99% of all open source software). Not that I would install it, I was just curious if there was one. I had Gentoo Linux running on my Power Mac G5 “Late 2005” with its 16 GB of DDR2 memory. It was great, only that Linux support sucks on the G5. This is true for both 32-bit and 64-bit, since this doesn't make that much of a difference with Gentoo Linux anyway. Okay, it doesn't suck, but there are some bits and pieces that aren't supported or that just don't work yet. The biggest problem is support for the graphics card. Most Linux drivers (like the X11 graphics drivers radeon for ATI cards and nv/nouveau for nVidia cards) require a PC compatible BIOS from the graphics card, which is not present in Power Mac versions of these cards, since they are made to work on Open Firmware instead of a PC compatible BIOS. Another is that closed source Linux applications –like Adobe Reader, Skype, Flash Player to name just a few– don't work on PowerPC. They are only available for Linux/x86 and sometimes (like Flash), but not always, for amd64 (the 64-bit version of x86). Some minor bits of hardware is not (yet) supported, like the ECC memory/EDAC driver for the CPC945 chipset of the “Late 2005” G5 (PowerPC 970MP). Thanks! Welcome! I hope that helped.

Re: Differences between single and dual G4 Quicksilvers
the boards are the same. period. you can certainly run a dual 800 from a QS 2001 in your '02 without any other modifications, and the benefit is not only two processors versus one, the single 800 on the QS 2002 (just like the single 733 on the QS 2001) has NO level 2 cache. none. there is a huge performance penalty from lack of L2 cache. that is why you cannot give away the processor cards from either a QS'01 733s or the QS'02 800s. virtually no one wants them. (i've got 5 of 'em if anyone is interested.) i have a QS'02 that originally had the 800 processor, and i replaced it with a dual 533 from a DA, and it works just fine. in bench tests with various utility apps and real work comparisons with real world apps, the dual 533 slightly outperforms the native single 933 that was available in the QS 2002. it is also a direct physical swap including the cooling fan and shroud, and no physical modifications are required. only drawback an minor hack is required to install 10.5.6. i have no clue what the other respondent to your question is thinking but ANY DP that physically fits the electronic connection will work. even the 450/500 DPs from a GE will work, except they won't have a power connector for the CPU fan. and all of the third part G4 DP upgrades work just fine, from AGP thru QS'02, no modifications necessary. the only DP CPUs that WON'T work are those from a MDD, because they physically won't fit, nor will the electronic connectors match up.

-- Original message -- Subject: Re: Differences between single and dual G4 Quicksilvers Date:Sonntag 17 Oktober 2010N From:Powermac teozen...@gmail.com To: G-Group g3-5-list@googlegroups.com So what are my options on the slow single G4-800 on a QS2002? As far as I know, every QS2002 processor card should work. I personally would grab anything that is low priced and a Dual processor for 133 MHz system buses. That is: * Dual-533 MHz from Digital Audio * Dual-800 MHz from Quicksilver * Dual-1 GHz from Quicksilver 2002 You cannot use a processor from an MDD or FW800, they are incompatible. You could use a Dual-450 or Dual-500 from a Gigabit Ethernet, but you'd have to move resistors, since these are for 100 MHz system buses. Examples: 4.5 × 100 MHz = 450 MHz 3.5 × 133 MHz = 465 MHz or 5.0 × 100 MHz = 500 MHz 4.0 × 133 MHz = 533 MHz You can see why the Digital Audio has a Dual-533 MHz instead of a Dual-500 MHz processor – the 133 MHz system bus. (Re)move the resistors like described in this link: http://power-mac-g4.com/g4clockup.html In the table “G4 JUMPER CHART”, set the Multiplicator CCU so that it gives the correct CPU speed for a 133 MHz bus. A CPU upgrade card from OWC, Sonnect, Newer Technology, FastMac, Giga Designs or PowerLogix is also a good option, but I recommend at least a Single-1.2 GHz for decent performance. These cards are often quite expensive, even used ones.
