Sorry, I missed that. How again? If you loose the LBA48 property Mac OS X will no longer be able to access beyond 128 GB. This is only dangerous if a partition starts before that limit and extends beyond this limit. How do you loose the LBA48 property? 1.) By zapping the NVRAM (pressing Opt-Cmd-N-V at the chime right after turning on your Mac). 2.) By resetting everything in Open Firmware. http://support.apple.com/kb/ht1379 3.) When your PRAM battery is weak it won't hold the information stored in NVRAM (time, start-up volume, LBA48-property, …)- 4.) When replacing the PRAM battery. What is important when partitioning for a non-LBA48-Mac? A.) Which Macs are non-LBA48? All before the Quicksilver 2002. B.) On which Macs does the OF hack work? All that use KeyLargo IDE chips. 1.) Partitions that contain any (Mac) OS should end at the 128 GB limit. 2.) Partitions that contain Data should start at the 128 GB limit. 3.) NO PARTITION should start before 128 GB and extend beyond. This is the ONLY danger: If a parition starts before the 128 GB limit, say: at 120 GB, and this partition has a size of 100 GB, so from 120 to 220 GB, and you loose the LBA48 property, but then access this partition… 1.) Mac OS X will see the first 8 GB of this 100 GB parition. It will read the contents of this file system and try to read beyond, and WRITE beyond, because this is what the partition and its file system HFS+ tell Mac OS X to do. 2.) All read/write accesses beyond the 128 GB limit will be “wrapped”. So, if Mac OS X reads the 100 GB partition's HFS+ file system, and wants to read a file which is, say, at 20 GB inside this file system, hence at 140 GB of the physical disk, this read/write call will be wrapped to the 140-128= physical 12 GB position of the drive. So you will corrupt the data of the first partitition. This very likely render your system unbootable some day! I hope this isn't too complicated. (I tend to write too much.) Just remember this: Using the LBA48 property on a Mac that doesn't support it (without hacking), ALWAYS end and start your paritions at 128 GB! Because then it won't see anything at all of the partition that extends beyond this limit, and so it cannot write-wrap anything, thus data corruption is not possible. Yes?

Re: Using HD 128GB in G4 Macs!
[ Excellent summary snipped ] I hope this isn't too complicated. (I tend to write too much.) Just remember this: Using the LBA48 property on a Mac that doesn't support it (without hacking), ALWAYS end and start your paritions at 128 GB! Because then it won't see anything at all of the partition that extends beyond this limit, and so it cannot write-wrap anything, thus data corruption is not possible. 1) The magic number is 131,072 megabytes. Partitions must be wholly below the 131,072 megabyte line, or they must be wholly above the 131,072 megabyte line. A partition which crosses the line, that is, it spans the line, is very likely to be useless on all pre-QS 2002 models. 2) If your Mac DOESN'T have a Key Largo ATA chip, but it DOES support MacOS X, then your alternative for large drive support is to use Intech's High Cap kext, which is in a much later revision, now, but was originally released back in the BW days, when 160 GB drives were first offered, when drives which exceeded 120 GB were first offered by manufacturers. At that time, the largest drive which Apple offered was 60 GB, which was FORMERLY the largest drive which was offered by manufacturers. You used to be able to get High Cap for free from OWC with the purchase of a large drive (120 GB), but no longer. Also, the old, free version of High Cap has been replaced by a version which supports the later MacOSes (later than 10.4.x, anyway). 3) Intech's software offerings include MacOS 9 support for large drives and MacOS X support for large drives. But this thread addressed the MacOS X issues, only. 4) It is possible to support large ATA drives by using a SCSIDE converter, and then attaching these ATA drives to a supported SCSI controller (Adaptec 29xx with Mac firmware, et. al.). SCSIDE has supported large drives for at least 10 years. SCSIDE was once the only way to support large drives on Macs, and I actually had a Beige G3 in which every hard drive was UW-SCSI or LVD/SE SCSI and used SCSIDE converters. An expensive solution, but it DID give large drive support when there was no other option. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Any fix for Safari slow-downs?
This is a G5 with 8GB of RAM running 10.5.8 and Safari 5.0.4. Why does Safari slow down more and more as you use it during the day? It works all right for a while, then when you want to scroll down a page or something, it throws up the spinning beachball, and there's a long delay before it does anything. And from that point the delays get longer and longer until the browser is so slow it's unusable. Emptying the cache makes no difference. Is there any way to fix this sluggishness when it happens?

A partition which crosses the line, that is, it spans the line, is very likely to be useless on all pre-QS 2002 models. Useless only when not hacking around this limit – either by using the LBA48 Open Firmware property or by modifying KeyLargo.kext to ignore this property. To be sure to start/end a partition at the 128 GB = 131,072 MB line, either leave some space inbetween or create your boot partition before applying the LBA48 hack, and then (using Linux mac-fdisk) make the rest of the drive usable in a partition which is in whole behind the 128 GB line. This may be a little complicated, but the best way to do it. There may be another way for the repartitioning after the LBA48 hack. But this needs to be tested/confirmed first. I only heard from users here in this forum that Disk Utility refuses to “activate” the rest of the disk for partitioning even with the LBA48 property, if it has been partitioned before without this property. This is due to the APM (Apple Partition Map) indicating the size of the disk, and this will simply say: 128 GB. The APM needs to be updated first, and the only way to do this so far is to use mac-fdisk in Linux. You used to be able to get High Cap for free from OWC with the purchase of a large drive (120 GB), but no longer. Also, the old, free version of High Cap has been replaced by a version which supports the later MacOSes (later than 10.4.x, anyway). Is there a location where this old and free High Cap has been preserved on the internet? What will the High Cap driver do on a G3 BW which has the buggy IDE chip CMD646, that has not only the slave drive issue, but also the UDMA incompatibility? Big drives are almost certainly UDMA (UltraATA) drives. 4) It is possible to support large ATA drives by using a SCSIDE converter, and then attaching these ATA drives to a supported SCSI controller (Adaptec 29xx with Mac firmware, et. al.). SCSIDE has supported large drives for at least 10 years. SCSIDE was once the only way to support large drives on Macs, and I actually had a Beige G3 in which every hard drive was UW-SCSI or LVD/SE SCSI and used SCSIDE converters. An expensive solution, but it DID give large drive support when there was no other option. Not an option for me. I got me an ACARD AEC-6280M ATA-133 expansion card that supports LBA48. It runs flawlessly so far, only S.M.A.R.T. is not supported. The drives are reported as SCSI disks, which is only ugly when using Mac OS X 10.5 (the drive icons indicate SCSI, but since they really are IDE, this isn't a good thing). But on the BW, obviously, I'm limited to Tiger anyhow.

This sounds either like a memory leak in Safari (some developer made a big mistake in Safari's program code) or maybe you have a memory problem in your G5.

ClickToFlash/Chameleon confusion
Recently I've noticed a couple cases where it appears two different software developers have created confusion by selected identical names for their products: The first is ClickToFlash where there appear to be two completely separate Safari products that do similar functions related to Flash content. The first I was aware of was this version, whose current revision is 1.5.5 stable and 1.6b9 beta: http://rentzsch.github.com/clicktoflash/ The second is this version, whose current revision is 2.2.1: http://hoyois.github.com/safariextensions/clicktoflash/ And this second version claims to be built upon a third version here, all with the same name ClickToFlash: https://github.com/mattball/ClickToFlash-safari-extension = The second case is on the Intel hackintosh side, where there is the case of Chameleon bootloader which is an all-in-one GUI bootloader for Intel PCs that can recognize and boot OS X, Windows, and Linux from a single GUI boot screen. Recently another developer decided to make some type of program for porting code between iOS and OS X, and this developer also selected the name Chameleon for their product. Again, there is no connection between these products, but just more confusion. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
