The fact that it is so easily rewritten with a change to the nvram (Non-volatile random access memory) makes me even more angry that the AppleKeyLargo kernel extension (.kext, aka driver) doesn't make this happen all by itself. To me (*IMHO*) this is a fake limitation, as there really is no limitation to New World Power Macs before the Quicksilver 2002.

large HDDs: 128 GB limit on Quicksilver 2001?
Hi! I would like to know if the limit of the pre-Quicksilver 2002 Power Macs is a hard limit or whether it can be managed to access beyond this barrier. I have a Quicksilver 2001, the 733 MHz model with an OWC Mercury Extreme G4 CPU Upgrade to 1,467 MHz and 1.5 GB of RAM. This doesn't look so bad, if only the hard drives could be larger. (The orginial disk is gone, an old 40 GB drive was installed which I removed.) My Power Mac: http://lowendmac.com/ppc/quicksilver-power-mac-g4.html The HDD I currently use was installed in a MDD Dual 1 GHz, which doesn't have the 128 GB limit. The size of the drive is 180 GB. Now in the Quicksilver 2001, the drive shows in System Profiler as a 128 GB drive. Mac OS X 10.4.11 Tiger is installed at the beginning of the disk on an 80 GB partition, so no problem there. I don't dare to access beyond, since the partitions are Ext2 filesystems (Linux) and I fear data corruption. I've read two contrary statements about the limit of 128 GB: Saying NO: http://support.apple.com/kb/HT2544 http://forums.xlr8yourmac.com/action.lasso?-database=faq.fp3-layout=FaqList-response=answer.faq.lasso-recordID=34188-search Saying YES: http://lowendmac.com/macdan/05/1024.html http://www.xlr8yourmac.com/IDE/big_ide_drive_support.html#storytop Although I cannot see if the Quicksilver users reporting that large drives work are really using the 2001 model. Anyone know more about this? Greetings to the g-list! I appreciate to be participating now. (This is my first posting.)

Search the G3-G5 list for LBA48 and you'll see several good discussions. Also get the free Mactracker from: http://www.mactracker.ca/ And it will show you your G4 does have the limitation. It can be overcome with an Open Firmware update, or an IDE PCI controller card.

Officially, the pre-QS 2002 ROM DOES NOT SUPPORT LBA48. Practically, is has been possible to add the required LBA48 properties to the Open Firmware facility for quite a number of G4 Macs, and possibly also for ALL New World Macs, of which the very first was the BW G3. Certainly, the High Cap kext works on all G3, ..., QS 2001 Macs. But, that kext works only after booting has been completed, and MacOS is fully operational. The LBA48 properties are always available, even during booting, as these are added to the ROM image. The High Cap kext is a useful tool, but it has had a number of revisions, and only the latest is usable on Leopard. The earlier versions DO NOT SUPPORT Leopard. The LBA48 properties are usable on ANY MacOS, even Leopard (but not on Snow Lepoard, as, obviously, Snow Leopard officially drops support for PPCs). You can choose to buy the latest version of High Cap, but I would not do so. The LBA48 properties are free, and work on any supported MacOS X. --~--~-~--~~~---~--~~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
